Painting warranties

Do not accept a warranty length as a quality signal on its own. A long warranty from a company with high staff turnover, or one written with broad exclusions, is worth less than a shorter one you can actually enforce. Read the exclusions before the number.

Common exclusions are reasonable and worth understanding: failures caused by moisture intrusion, structural movement, substrate rot, mildew, fading from UV, and surfaces the homeowner asked to be painted against the contractor's recommendation. Horizontal surfaces — decks, railings, sills — are often excluded or covered for a shorter period because they hold water.

For manufacturer warranties, ask for the actual written warranty document from the product's data sheet. Do not accept a verbal description of coverage from a salesperson. Coating warranties commonly cover the product only, require proof of purchase, and depend on the product having been applied per the manufacturer's instructions.

Ask one practical question: what does the claim process look like? Who do I call, how fast do you respond, and does the warranty transfer if I sell? A contractor with a clear answer has handled claims before.

How to choose

Get the warranty as a document, not a sentence

Length, what's covered, what's excluded, how to claim, and whether it's transferable.

Read the exclusions first

Moisture, substrate condition and horizontal surfaces are the usual carve-outs. Know them before a failure, not after.

Ask for the manufacturer's written warranty too

Request the product data sheet and warranty PDF for the exact product line being used. Never rely on a spoken claim.

Understand what voids it

Homeowner-supplied paint, homeowner touch-ups, or bringing in another painter to fix a failure will usually end the coverage.

Report failures in writing, early

Photograph the failure, email the contractor, keep the thread. Verbal complaints don't create a record.
