Know what your paint job *should* cost — before you ever talk to a painter. PaintTap is an honest, AI-powered exterior paint estimator built for homeowners who are tired of "we'll send someone out for a free quote" sales pitches. Tell us where your home is and snap three photos. We measure the walls, count the trim, score the surface condition, then price it against local labor and paint costs. You get a fair-price range — yours to keep for 90 days, with no salespeople attached unless you ask for one. WHAT YOU GET • A specific fair-price range — not a national average • Cost breakdown: body paint, trim paint, primer, prep labor, paint labor, materials, disposal • Recommended paint brand and finish for your surface type • Prep checklist for the painter to follow • Three color palettes that fit your home's era and roofline • Local rates baked in — Bay Area labor ≠ Tulsa labor WHY IT WORKS PaintTap uses AI to measure your home's exterior the same way a contractor would on a site walk — but in 60 seconds. If you can't get clean photos (or just don't want to bother), we'll use satellite imagery and public records to estimate from your address alone. You'll see exactly which method we used. WHEN YOU'RE READY FOR A PAINTER Tap the button. We'll connect you with a vetted local painter who already sees your estimate and the fair-price range — no high-pressure sales calls, no haggling on a number we already agreed on. NEVER SOLD WITHOUT PERMISSION Your contact info doesn't go anywhere unless you explicitly opt in. Everything stays inside PaintTap — your estimate, your data, your decision. Whether you're prepping for a sale, planning a refresh, or just sanity-checking a contractor's quote, PaintTap gets you a defensible number in the time it takes to walk around the block.
