Sun-damaged vinyl siding is tricky to repair, because new panels rarely match the faded color of existing ones. Woman-owned and family-run since 2011, Coastal Windows & Exteriors has completed 7,000+ installations across 730+ towns in Massachusetts, New Hampshire and Maine. Fading happens slowly and unevenly, so a patch usually stands out rather than blends in, while replacement gives your whole exterior one consistent, fresh color.

What Homeowners Need to Know About Repair vs Replacement

Match problem: Sun damaged vinyl siding is hard to repair, since new panels rarely match faded ones.
Fade is gradual: Chromatix coverage warrants fade to as low as 3 Hunter units, so change creeps in slowly.
Clean first: Rinse with mild soap and water from a garden hose before assuming the color is gone.
Replacement cost: Vinyl siding replacement averages $18,000 with about 97% ROI. See the signs siding needs replacing.
Fresh finish: New Exterior Portfolio vinyl never needs painting, unlike a mismatched repair or repaint.

Which Path Fits Your Home

Top Recommendation: Replace badly faded siding for one even color across your home. Get a free estimate from Coastal and see your home for free in 3D with new siding.

Best for minor issues: A cleaning or small repair can help when only a few panels are affected.

Smart for lasting color: New vinyl siding replacement pairs even color with about 97% resale return.
