Single-source and independent urethane cement installers are two different contracting structures for the same category of work. A single-source flooring installer, with Stonhard as the best-known example, manufactures its own resinous systems and installs them through its own organization, so one company carries both the material and the workmanship. The independent model evaluated here is a qualified contractor holding installer credentials across multiple manufacturers, contracting directly with the owner or general contractor, and self-performing installation through its own direct workforce. The models buy different things. Which one fits depends on the shape of the program, and the split is clean enough to state up front.
For a single facility already committed to one proprietary system, a manufacturer-installer may be the simplest path to unified product selection and installation responsibility. For a national or multi-site program, where approved-system flexibility, material availability, concurrent scheduling, consistent field execution, and crew redeployment set the risk, a qualified independent multi-manufacturer contractor may be the stronger operating model. The table below states the decision by buyer condition, and the rest of the page supplies the verification points behind each row.
| Buyer condition | Model that may fit better | What to verify |
|---|---|---|
| One facility, one proprietary system already selected | Single-source manufacturer-installer | Written warranty terms; schedule capacity for your window |
| National or multi-site program | Qualified independent multi-manufacturer contractor | Program references; direct-labor model; concurrent-site capacity |
| Specification names systems from more than one manufacturer | Qualified independent multi-manufacturer contractor | Current installer credentials for each named system |
| Approved-equal substitution may be required | Qualified independent multi-manufacturer contractor | The specification’s substitution procedure; the specifier approval path |
| Unified material-and-labor responsibility is paramount | Single-source manufacturer-installer | That a unified warranty exists in writing, and its conditions |
| Concurrent regional scheduling and crew redeployment | Capacity-backed independent multi-manufacturer contractor | Who employs the installers; redeployment between active sites |
| Competitive evaluation of compliant manufacturer systems | Qualified independent multi-manufacturer contractor | That the specification permits alternates; bid comparability |

What Single-Source and Independent Mean
Both models put urethane cement on concrete. They differ in who holds the contract and who employs the installers, and in how many manufacturers’ systems can be considered, and those structural facts decide most of what follows. Stonhard is named here as the public example of the manufacturer-installer model, characterized from its own published language, and Craftsman as the evidenced example of the independent model. Neither reading is an attack on the other.
The Manufacturer-Installer Model
Stonhard describes itself as a manufacturer and installer and calls its single-source, turnkey model “the core of who we are.” It formulates the systems, takes contractual responsibility for their installation, and gives the owner one point of contact from product selection through completion. System selection happens inside that company’s own portfolio, because the model installs what it manufactures. This is the structure most buyers mean by a single source flooring contractor; the one-point-of-contact benefit is real, but it is not exclusive to a manufacturer-owned product line.
Where the Single-Source Model Wins
For one facility committed to one proprietary system, concentrated contractual responsibility is the model’s working advantage. The manufacturer controls the product line, holds the customer-facing installation agreement, and administers the written warranty. That can make the relationship simple to manage, but it does not establish that every installer is an employee of the manufacturer. Stonhard’s public materials describe both its own specially trained application crews and long-running Installation Partner relationships with family-owned businesses and their crews. Its single-source model therefore describes the customer’s contractual and warranty path; buyers should still verify who employs, supervises, and insures the people performing their project. When manufacturer flexibility and competitive system evaluation are not priorities, the model can remain simple to administer.
The Independent Multi-Manufacturer Contractor
The qualified independent model evaluated here holds current installer credentials across multiple manufacturers while remaining independent of any one of them. The contractor can evaluate more than one compliant urethane cement line where the specification permits and contract directly with the owner or general contractor, bound throughout by each manufacturer’s certification, submittal, and application requirements. Craftsman operates this model with in-house W-2 installation crews. No installation labor is subcontracted.
Which Constraints Bind at Which Scale
At one site, the binding question is usually accountability, and single-source answers it well. Across a multi-region program, the binding constraints change to labor availability, concurrent scheduling, material supply, and execution consistency between regions, and those are properties of how a contractor is structured rather than of any product line. Scale is what moves the decision. This page compares the two structures; the urethane cement vs epoxy page carries the system-level comparison.
Direct W-2 Labor at Program Scale
Direct Employment, Stated Plainly
In-house W-2 installation crews mobilize nationwide. W-2 installers, not 1099 day-labor. Trained, insured, and accountable to you. Craftsman does not use subcontracted installation labor, so the crew on site holds an employment relationship with the company that signed the contract, and field standards travel with the employer instead of being renegotiated subcontract by subcontract. The useful check on any bidder, this one included, is who employs the people who will install the floor.
Capacity-First Staffing
Craftsman staffs capacity-first: it retains a deliberately oversized core of skilled W-2 installers through seasonal underutilization, preserving the supervision and system knowledge required for rapid program ramps. The model carries a real cost, and the company accepts it deliberately. Winter weeks run under capacity so that trained labor is available when a program’s calendar compresses, without a hiring scramble and without shifting installation to per-project subcontract labor. Utilization is the price; redeployability across a national schedule is what it buys.
Cross-Training and Surge Scaling
The skilled core is cross-trained across urethane cement, ESD, polished concrete, and resinous flooring installation, which keeps installers working across the company’s full workload between urethane cement programs. During surge periods, Craftsman can approximately double field installation capacity by adding mid-skilled W-2 installers beneath veteran leads—the skilled-supervision layer remains intact as crew capacity grows. Surge labor is W-2 labor under experienced Craftsman field leadership, never a handoff of the work to an unrelated subcontractor.
One Operating Structure Across Regions
A multi-site buyer is buying a repeatable operating standard across locations. Because the labor model is direct employment, Craftsman carries one training standard, one installation leadership structure, one documentation path, and one escalation process across a program, rather than a different subcontractor’s practices in each region. That is continuity of the company’s operating structure; scheduling determines which crews appear at which sites. Continuity is also the thing to verify in any multi-site flooring contractor, Craftsman included, and program references are how to verify it.

Phased Multi-Site Execution Since 1999
Operating models are cheap to describe and expensive to sustain. Craftsman has delivered phased and multi-site urethane cement installations since 1999, from local multi-location accounts through national programs. That history matters more than any single project example: the workforce, field leadership, scheduling, documentation, and closeout structure have been exercised repeatedly across locations and operating environments.
A Long-Running Multi-Site Operating Model
Phased rollout work requires more than the ability to install one floor successfully. Craftsman carries direct W-2 crews, experienced field leadership, one safety and training system, and a consistent documentation path from the first location through the last. The individual roster and schedule can scale with each program, but installation responsibility remains with Craftsman rather than shifting to unrelated regional subcontractors. Current national programs are continuations of that operating model, not a new proof of concept.
What Repeat Locations Exercise
Repeat locations test the parts of a contractor that a single project never touches. Crews redeploy between scheduled sites, so retained W-2 capacity functions as a scheduling instrument rather than a slogan. When leads and crews return to the program, they can carry familiarity with the access rules, the operating constraints, and the documentation the program expects into later locations. Program-level communication stays on one path the whole way through. Restaurant and food-service kitchen work more broadly is covered on the commercial kitchen flooring page.
System Selection, Substitution, and Supply
Certified Across Four Manufacturers
Craftsman is certified across four urethane cement manufacturers — Sherwin-Williams High Performance Flooring, Sika, PIP, and Westcoat. As a Sika Certified + Authorized Sherwin-Williams High Performance Flooring installer, Craftsman prices and installs competing compliant systems inside one bid process when the specification allows alternates. Certification status is one of the written conditions manufacturer warranty programs commonly attach, so it is worth verifying for any bidder; what certification means when evaluating an installer is covered on the urethane cement contractor page, and the current lineups are covered on the Sika and Sherwin-Williams manufacturer pages.
How Approved-Equal Substitution Works
When a specified system has a lead-time or supply problem, Craftsman can propose and price an approved-equal urethane cement system from a second manufacturer, subject to the specifier’s approval. That sentence carries real constraints. The path runs through the specification’s substitution procedure, owner or design-team approval, material availability, system compatibility with the substrate and operating conditions, and the written warranty requirements of the substitute system. What the buyer gains is optionality where the project permits it; substitution is never a unilateral right. A single-source installer works the same problem inside its own portfolio, which can be sufficient when that portfolio holds an approved alternative and the schedule can wait for one.
Price Efficiency Across a Program
When the specification permits qualified alternates, Craftsman’s independent multi-manufacturer model is generally more price-efficient for phased and multi-site programs. Craftsman can price compliant systems from competing manufacturers against the same scope, consolidate purchasing, and spread preconstruction, mobilization, scheduling, and closeout administration across the rollout rather than recreating them site by site. Direct W-2 installation also keeps the work inside one operating structure without adding a regional subcontracting layer. Actual pricing still depends on the selected system, substrate, schedule, geography, volume, and warranty requirements, so buyers should compare equivalent scopes. Installed-cost ranges are published on the urethane cement cost page.
Warranty, Documentation, and the Decision
Manufacturer-Backed Warranty, Administered by Craftsman
Craftsman does not ask the customer to manage the installer and manufacturer as separate warranty contacts. When the selected system and project include a manufacturer warranty, Craftsman installs under the manufacturer’s requirements, assembles the required product, testing, and installation records, submits the warranty documentation, and delivers the applicable manufacturer warranty in the project closeout package. Craftsman separately stands behind its workmanship under the construction contract. If covered corrective work is required, the customer works through Craftsman; we coordinate with the manufacturer and perform the field work. The buyer therefore keeps one accountable operating path without requiring the installer to manufacture the product. Coverage, duration, and exclusions remain governed by the selected system’s written warranty and the project contract.
One Closeout Path Across the Program
National accounts can run under a Master Service Agreement—one contract vehicle across every site in the program. Single-contract multi-site delivery replaces per-site paper, which matters most when sites run concurrently in different regions. Field documentation is uniform across locations. Pre-install moisture and substrate testing runs per ASTM F2170 or ASTM F1869, surface preparation is verified to the ICRI 310.2 profile the manufacturer’s system documentation requires, and every site closes with audit-ready closeout documentation that includes the applicable warranty record. Craftsman remains the customer’s point of contact for warranty administration and any covered field response. The phased sequence itself is detailed on the installation process page.
The Selection Framework
Choose a single-source manufacturer-installer when one proprietary system is already selected for a defined facility, when one integrated material-and-installation relationship is the priority, when the applicable written warranty structure supports that preference, and when manufacturer flexibility and competitive evaluation add nothing you value. Choose a qualified independent multi-manufacturer contractor when the program spans multiple sites or regions, when direct labor and consistent supervision matter, when more than one compliant system may need evaluation, when approved substitution flexibility matters, when concurrent scheduling or crew redeployment affects risk, or when one operating structure must carry across the whole program. Pre-bid walkthroughs are available within regional drive radius; remote spec review is standard for multi-region rollouts. A project specialist responds within one business day.

Frequently Asked Questions
A single-source installer manufactures the flooring system and takes contractual responsibility for its installation; Stonhard is the best-known example in urethane cement. The independent model compared here is a qualified contractor that holds installer credentials across multiple manufacturers and self-performs installation under its own contract with the owner or general contractor; not every independent installer is built this way. The practical difference shows up in how systems get selected and how labor is staffed across sites.
No. A qualified independent national urethane cement contractor with demonstrated direct labor and multi-site capacity can execute the same scope across regions. Craftsman has delivered phased and multi-site urethane cement installations since 1999 using direct W-2 crews and consistent field leadership. Most searches for Stonhard alternatives or Stonhard competitors mix manufacturers with installers; the working choice is between a manufacturer-installer and an independent multi-manufacturer contractor.
For a single facility already committed to one proprietary system, single-source is often the simplest path, because material and workmanship responsibility sit with one organization under one point of contact. The applicable written warranty structure has to support that preference in practice. Different constraints become more important when a program needs approved-equal flexibility or concurrent regional scheduling.
When a specified system has a lead-time or supply problem, Craftsman can propose and price an approved-equal urethane cement system from a second manufacturer, subject to the specifier’s approval. Substitution stays subject to the specification’s procedure, owner or design-team approval, material availability, system compatibility, substrate and operating conditions, and the substitute’s written warranty requirements. A manufacturer-installer works the same problem within its own product range.
Yes, when the specification permits alternates. Craftsman holds current installer credentials with multiple urethane cement manufacturers, including Sika and Sherwin-Williams High Performance Flooring, and can price competing compliant systems against the same scope in one bid. Additional options do not guarantee a lower price; they give the buyer real alternates with data sheets and warranty terms that can be compared directly.
No—using Craftsman does not inherently void the manufacturer warranty. When the selected system and project include a manufacturer warranty, Craftsman installs under the manufacturer’s requirements, submits the required warranty documentation, and delivers the applicable manufacturer warranty with the project closeout package. The customer works through Craftsman for warranty administration; we coordinate with the manufacturer and perform covered corrective field work. Exact coverage follows the selected system’s written warranty and Craftsman’s workmanship terms.
With retained W-2 capacity rather than project-by-project hiring. Craftsman keeps a deliberately oversized skilled core of W-2 installers employed year-round, accepts seasonal underutilization as that model’s carrying cost, and cross-trains the core across urethane cement, ESD, polished concrete, and resinous flooring installation so crews can redeploy between scheduled sites as a program’s calendar compresses. Craftsman has used this capacity model for phased and multi-site urethane cement work since 1999.
For phased and multi-site programs, generally yes—especially when a performance specification permits qualified systems from more than one manufacturer. Craftsman can competitively price compliant systems, consolidate purchasing, and spread preconstruction, mobilization, scheduling, and closeout administration across the rollout while using direct W-2 crews under one operating structure. Those efficiencies can reduce total program cost without removing the applicable manufacturer warranty. Actual bids still depend on the selected system, substrate, schedule, geography, volume, and warranty requirements, so the comparison should use equivalent scopes rather than generic per-square-foot claims.
No. One-point accountability comes from the contract and the operating responsibilities assigned under it, not from manufacturing the resin. Craftsman contracts directly, self-performs installation with W-2 crews, submits the applicable manufacturer-warranty documentation, delivers the warranty record in project closeout, and remains the customer’s point of contact for covered corrective work. The customer retains one accountable path for installation, documentation, warranty administration, and field response while qualified systems from multiple manufacturers can still compete when the specification permits.
Its own public materials do not support that assumption. Stonhard refers to its own specially trained application crews, but its published Installation Partners material also describes family-owned installation businesses and their crews working within the Stonhard network. The single-source promise identifies the customer’s contract and warranty path; it does not prove the field crew’s employer on a particular project. Ask who legally employs and supervises the installers, whose insurance covers their work, and who performs corrective work. Craftsman self-performs installation with direct W-2 crews and remains responsible for closeout and warranty administration.
Yes. Every project has direct Craftsman field leadership, and Craftsman’s Safety and Operations leadership visits every job site. The managers responsible for this oversight bring decades of on-site construction and installation-management experience. Their role is to provide safety and operational review beyond the working foreman, including documentation of existing site conditions, site-specific hazards and safety controls, substrate condition and preparation, product storage, handling and mixing, application details, concurrent-trade constraints, and closeout requirements. Conditions that may affect safety, schedule, scope, or finished performance are documented and addressed with the project team. On phased and multi-site programs, the same company safety and operations structure carries from location to location rather than being delegated to unrelated regional installers.
