How to Hire a Bathtub Refinisher: Checklist and Red Flags

Bathtub refinishing is a small job by remodeling standards, but the chemistry involved is not small. Contractors spray isocyanate-based coatings in an enclosed bathroom, sometimes strip old finishes with aggressive chemical strippers, and leave behind a surface your family will step onto wet for the next decade. The gap between a qualified professional and a weekend operator with a spray kit from the internet is wide, and it’s not always obvious from a quote or a website.

This isn’t a field with a single national license. There’s no universal certification that tells you a contractor knows what they’re doing. What there is: a set of concrete questions, documents, and signals that separate contractors who have their operation together from those who don’t. Work through these before anyone shows up at your door.

A quick note on terminology: “refinishing,” “reglazing,” and “resurfacing” mean the same thing. Contractors use all three interchangeably. Don’t let terminology differences distract you from the questions that actually matter.

Licensing: There Is No National Standard, So Check Your Own State

This is the part most homeowners skip because they assume a licensed contractor is a licensed contractor. It’s not that simple.

Contractor licensing for bathtub refinishing varies dramatically by state. California requires a license through the Contractors State License Board (CSLB) for most home improvement work. Florida’s Department of Business and Professional Regulation (DBPR) has a specialty contractor framework that may apply. Texas runs licensing through the Texas Department of Licensing and Regulation (TDLR). Other states have no statewide license requirement at all and rely on local business permits.

Don’t assume. Look up your state’s licensing board before your first call. Ask any contractor you’re considering to provide their license number, then verify it yourself on the board’s website. A contractor who can’t give you a license number in a licensed state is already a problem.

In states with no statewide requirement, the bar shifts. Local business registration, general liability insurance, and workers’ compensation coverage become your primary verification tools, as NAHB Remodelers notes. More on insurance verification below.

Insurance: Get the Certificate Directly from the Insurer

General liability and workers’ compensation are both non-negotiable. General liability covers damage to your property if something goes wrong. Workers’ comp covers the technician if they’re injured in your home. Without workers’ comp, a technician hurt on your job can potentially come after your homeowner’s insurance.

Don’t accept a copy of an insurance certificate the contractor hands you or emails you. Copies can be outdated. Policies lapse. Ask the contractor to have their insurance company send a Certificate of Insurance (COI) directly to you before work starts. This takes one phone call on their end, and a contractor who pushes back on this request is telling you something.

PRG Membership: What It Means and What It Doesn’t

The [Professional Refinishers in Brooklyn](../cities/brooklyn.html) Group is the recognized trade association for the bathtub and surface refinishing industry. You can verify a contractor’s claimed membership through the PRG’s online directory.

PRG affiliation signals that a contractor has connected with the industry’s primary professional body, which provides training resources, technical guidance, and a code of ethics. That matters. An operator who doesn’t know the PRG exists is unlikely to be current on industry safety protocols.

PRG membership is not a license. It’s not an insurance guarantee. Treat it as one meaningful positive signal in a broader picture. A contractor who has PRG membership, current insurance, verifiable licensing, and can answer the questions below is in good shape. PRG membership alone doesn’t get them there.

EPA Compliance: Two Separate Issues, Often Confused

“EPA certified” is one of the most misused phrases in this industry. When a contractor says their products or methods are “EPA certified,” ask exactly what program they’re referring to. There is no general EPA certification for refinishing chemicals or techniques.

The one EPA certification that genuinely matters for many jobs is RRP firm certification under 40 CFR Part 745. If your home was built before 1978, any refinishing work involving sanding or stripping original surfaces may disturb lead-containing paint or enamel. The contractor’s firm must be EPA-certified under the Renovation, Repair and Painting Rule, and the individual technician must be a certified renovator. Ask to see the firm’s RRP certification number and verify it through the EPA’s database. Failure to comply carries significant civil penalties, and more importantly, it means lead dust in your bathroom.

For homes built after 1978, RRP certification is not required. In that case, “EPA certified” in a contractor’s pitch is probably marketing noise. Don’t let it substitute for asking about actual chemical handling practices.

The second chemical issue is isocyanates. Most professional two-component polyurethane refinishing coatings contain them. The EPA identifies isocyanates as the leading attributable cause of occupational asthma in the United States. They off-gas during and after application, and the risk doesn’t disappear the moment the contractor packs up. The coating needs to fully cure before the space is safe for regular occupancy. How long that takes depends on the specific product, the ambient temperature, and the humidity in your bathroom. A contractor who quotes you a single universal number without referencing the product’s Technical Data Sheet doesn’t have a firm grasp on what they’re applying.

Coating Products: Ask for the TDS and SDS Before You Sign Anything

This is one of the clearest separators between professional operators and weekend warriors.

Reputable coating manufacturers publish Technical Data Sheets (TDS) and Safety Data Sheets (SDS) for their products. Ekopel 2K, Napco, Multi-Tech, and similar professional-grade coatings all have this documentation. The TDS specifies mixing ratios, required application thickness, VOC content, coverage rates, temperature and humidity conditions required for proper adhesion, and cure time before the surface can be used. The SDS covers the chemical hazard profile.

Ask the contractor: “What coating product are you using, and can you provide the TDS and SDS?” A professional should answer the first question without hesitation and have the documents accessible. If they can’t name the product, or they name it but won’t provide the documentation, walk away.

One specific question worth pulling from the TDS: slip resistance. ASTM F462-79(2020) sets a minimum wet static coefficient of friction of 0.04 for bathing surfaces. A refinished tub surface that doesn’t meet this threshold may actually be more slippery than the original factory surface. Ask whether the coating the contractor proposes has been tested against ASTM F462.

A word of caution here: ASTM doesn’t certify contractors or products. It publishes test method and performance standards. A contractor claiming their coating is “ASTM certified” is using imprecise language. What you want is test data showing the applied coating meets F462 performance requirements, not a vague certification claim.

Ventilation and Safety Protocol: The Questions That Reveal the Most

Ask these directly. The answers tell you more than almost anything else.

“What ventilation do you set up before spraying?” Under OSHA 29 CFR 1910.94(c), spray finishing operations require solvent vapor concentrations to be kept below 25 percent of the lower explosive limit through engineering controls or combined respiratory protection. In a bathroom, that means exhaust fans actively moving air out of the space, not just a window cracked open. A contractor who says “we open the windows” without describing any mechanical exhaust equipment is describing a setup that’s likely out of compliance.

“Are your technicians fit-tested for their respirators?” OSHA 29 CFR 1910.134 requires contractors using respirators in spray-coating operations to maintain a written respiratory protection program, including medical evaluations and fit testing for each technician. A contractor who can say “yes, we have a written program and our techs are fit-tested” understands the regulatory environment they operate in. One who looks confused by the question doesn’t.

“Do you use any chemical strippers containing methylene chloride?” Some contractors still use methylene chloride-based strippers on stubborn old finishes. OSHA’s standard at 29 CFR 1910.1052 sets a permissible exposure limit of 25 ppm as an 8-hour time-weighted average and requires air monitoring, written exposure control plans, and appropriate respiratory protection. If a contractor uses these strippers, they need to describe their compliance program. If they don’t know what you’re asking, the answer is effectively “no, we’re not compliant.”

Reading Online Reviews Without Being Fooled by Them

Reviews are useful but require some interpretation.

Response patterns on complaints matter most. The BBB notes that a pattern of unresolved complaints is more diagnostically significant than the presence of complaints alone. Every contractor who does enough volume will have a dissatisfied customer eventually. What separates professional operations is whether they respond and resolve. A contractor with 4.2 stars and 80 reviews who responds professionally to every negative review is more trustworthy than one with 5.0 stars and 6 reviews.

Very few reviews with a perfect score deserves scrutiny. The BBB specifically flags this. A brand-new profile with a handful of glowing reviews tells you almost nothing about a contractor’s track record.

Look for specificity in positive reviews. Generic “great job, very professional” reviews carry less weight than ones that describe specific details: what the tub looked like before, how the tech handled prep, whether the quoted price matched the final invoice. Specificity is harder to fake and harder to manufacture in bulk.

Complaints about smell, health symptoms, or re-occupancy confusion are red flags. If multiple reviewers mention being forced back into the space too soon, or describe headaches and respiratory irritation following the job, the contractor is not handling curing protocols appropriately.

If you’re comparing local options, professional tub refinishers in New York can often be cross-referenced against state licensing databases to confirm the names you find online.

Red Flags in Quotes and Contracts

Some problems announce themselves before work starts.

Large upfront cash payment required. The FTC recommends never paying the full amount upfront, and a cash-only demand with a large deposit is a classic exit strategy for operators who don’t intend to stand behind their work. A reasonable deposit for materials is normal. Half or more upfront in cash is not.

No written contract, or a vague one. A legitimate contract should specify the coating product by name and the number of coats, all prep work included, the total price and payment schedule, start and completion dates, the re-occupancy timeline from the product’s TDS, and what the warranty covers. “1-year warranty” without exclusions is meaningless. Get the exclusions in writing.

A warranty that doesn’t define what voids it. Most professional coating warranties are voided by cleaning with abrasive products, by using bath mats with suction cups, or by impact damage. Those are reasonable exclusions. A warranty that says “damage from normal use” is a warranty that won’t pay out. Read it before signing.

Quoted cure time that’s shorter than what the TDS specifies. If a contractor tells you the tub will be ready in 4 hours and the TDS for the coating they’re using says 24 to 48 hours under your humidity conditions, that’s not a scheduling convenience. That’s a contractor who either doesn’t read product documentation or doesn’t follow it.

No mention of prep work. Surface prep is where most refinishing jobs fail or succeed. Etching, cleaning, and adhesion promotion take more time than the spray application itself. A quote that doesn’t describe prep steps, or that seems priced too low to include them, is a quote for a job that will peel in 18 months.

Before You Book

Once you have quotes from two or three contractors who’ve passed these checks, the decision gets simpler. Price matters, but it’s rarely the right primary criterion when you’re comparing operators who’ve demonstrated competence against those who haven’t. A refinishing job done correctly should last 10 to 15 years. The math on paying a bit more for a contractor with proper documentation, verifiable insurance, and clear safety protocols tends to work out.

If you’re comparing providers in your state, start with your state’s licensing board, then layer in the questions from this checklist. The contractors who answer without hesitation are the ones worth hiring.

Frequently Asked Questions

What’s the difference between bathtub refinishing, reglazing, and resurfacing?

Nothing, for practical purposes. The three terms are used interchangeably across the industry and all describe the same process: cleaning, etching, and applying a new topcoat to an existing tub surface. The word a contractor uses tells you little about their quality.

Do I need to verify EPA certification even if my home was built after 1978?

If your home was built after 1978, the EPA RRP Rule does not apply to your job, so lead-safe certification is not required. For homes built before 1978, any refinishing work that involves sanding or stripping original surfaces triggers the RRP requirement, and the contractor’s firm must hold current EPA certification under 40 CFR Part 745.

How do I verify that a contractor actually carries current insurance?

Ask the contractor to have their insurer send a Certificate of Insurance (COI) directly to you. A contractor-provided copy can be outdated or altered. NAHB Remodelers recommends this step specifically because coverage can lapse between when a copy was made and when work begins.

What is PRG membership and does it guarantee quality work?

The Professional Refinishers Group is the main trade association for the bathtub refinishing industry in North America. Membership signals that a contractor has affiliated with the industry’s recognized body and agreed to its code of ethics. It is not a license, not an insurance guarantee, and not a formal quality certification. Treat it as one positive signal among several, not a substitute for checking credentials and references.

What should a written contract for tub refinishing include?

At minimum: the specific coating product by name, the number of coats, prep steps included, total price, payment schedule, start and completion date, re-occupancy timeline from the product’s TDS, and what the contractor’s warranty covers and excludes. The FTC recommends getting all of this in writing before work starts.
