Salt air
Airborne salt settles on siding and trim and keeps working at the film and at fasteners. Washing it off is the difference between a coat that bonds and one that lifts.

How we work
How does an exterior repaint work?
A repaint in Wilmington is not the same job as a repaint two hours inland. Salt air, strong sun, and humidity attack a finish from every direction, so the coating is only as good as the surface underneath it. We rebuild that surface first, then topcoat.
Our five-step exterior process
- Walk the exterior. We check every elevation for failing paint, soft wood, open caulk joints, and mildew, then write the scope around what we find.
- Wash. Coastal siding carries salt film, pollen, and mildew. Nothing gets painted until the surface is washed and dry.
- Repair & scrape. Rotted trim, fascia, and siding are replaced; failing paint is scraped and sanded back to a sound edge.
- Caulk & prime. Joints, windows, doors, and penetrations are re-caulked, and bare wood and repairs are spot-primed.
- Topcoat & walk it. Two-coat 100% acrylic finish on siding and trim, staged around the forecast, then a walkthrough with you before we pull off.

Coastal conditions
Why exterior paint fails faster near the coast.
Four local conditions drive how we specify and schedule every exterior in New Hanover and Brunswick counties.
UV exposure
South- and west-facing elevations chalk and fade first. We check those walls closely and, where budget is tight, prioritize them over shaded sides.
Humidity & mildew
Summer humidity slows dry times and feeds mildew on shaded north walls. Those areas get cleaned and treated before coating, never painted over.

Project snapshot
What to expect at a glance.
The details Wilmington homeowners ask about first — timing, coatings, warranty, and what happens when the weather turns.
Best seasons to paint
Spring and fall are the most reliable windows here: surface temperatures stay in range, humidity is lower than midsummer, and there is less risk of an afternoon storm reaching a fresh coat.
Storm season planning
Atlantic hurricane season runs June 1 to November 30. Open caulk joints and failed trim are where wind-driven rain gets in, so sealing is scoped before topcoat.
Weather delays
We stop before rain reaches wet coatings and resume once surfaces are dry. Weather moves the schedule, not the scope or the estimate, and you get the new plan the same day.

Surfaces we paint outside
What each exterior substrate needs
Siding type decides the prep and the product. Here is what we look for before we write a scope.
| Substrate | What it needs | Watch for |
|---|---|---|
| Wood siding & trim | Scrape, sand, replace rot, spot-prime bare wood | Soft fascia and window sills, open end-grain joints |
| Fiber cement | Wash, re-caulk butt joints, acrylic topcoat | Failed caulk at joints and trim boards |
| Vinyl siding | Wash, bonding primer, vinyl-rated color | Dark colors not rated for vinyl can warp panels |
| Brick & stucco | Clean, patch, breathable masonry coating | Trapped moisture behind non-breathable films |
| Porches, railings & doors | Degloss, prime, durable enamel | Foot traffic, hand contact, and standing water |
Where we paint exteriors
Homes & buildings across the coast.
The same prep standards cover an inland ranch, a beachfront rental, and a commercial building envelope.
Wilmington & Leland homes
Older wood exteriors in Forest Hills and Sunset Park, newer fiber cement and vinyl in Mayfaire, Leland, and Castle Hayne — each gets the prep and coating system its siding actually calls for.
Beach & waterfront properties
Wrightsville Beach and Carolina Beach homes and rentals take the worst of the salt air and sun. Work is scheduled between bookings where owners need it, with photos sent as elevations finish.
Commercial building envelopes
Tilt-up, brick, stucco, and metal panel exteriors get cleaning, caulking, and coatings that resist salt air and UV — see our commercial & industrial services.
Exterior FAQ
Exterior painting questions Wilmington homeowners ask.
Straight answers on timing, coastal durability, prep, and siding types before we start.
01When is the best time to paint a house exterior in Wilmington?+
Spring and fall are the most reliable windows in Wilmington. Surface temperatures stay in range for exterior acrylics, humidity is lower than midsummer, and there is less risk of an afternoon thunderstorm reaching a fresh coat. Summer work is possible when we start early and stay ahead of the heat, and we plan around the Atlantic hurricane season, which runs June 1 through November 30.
02How long does exterior paint last on a coastal home?+
Coastal exposure shortens the cycle compared with inland homes. Salt-laden air, direct sun, and wind-driven rain wear finishes fastest on south and west elevations and on anything facing open water. Prep quality is the biggest variable: a washed, repaired, primed, and properly caulked exterior holds far longer than a repaint applied over chalking paint.
03What prep do you do before painting an exterior?+
We wash the exterior to remove salt film, pollen, dirt, mildew, and chalking; scrape and sand failing paint; replace rotted trim and siding; re-caulk joints, windows, and penetrations; and spot-prime bare wood and repairs before topcoating. On the coast the prep is the job, and paint is the last step.
04Do you paint vinyl, fiber cement, brick, and stucco?+
Yes. Wood, fiber cement, brick, stucco, and vinyl all take coatings, but each needs its own prep and product. Vinyl requires colors rated for vinyl so panels do not warp, masonry needs breathable coatings, and fiber cement needs sound caulk at butt joints. We confirm the substrate and specify the system during the estimate walkthrough.
05What happens if it rains during my exterior project?+
We stage exterior work around the forecast and stop before rain reaches wet coatings, then resume once surfaces are dry. Weather delays move the schedule, not the scope or the estimate, and we tell you the new plan the same day rather than leaving a half-finished elevation exposed.
