Exterior Painting
A.G. Williams Painting Company plans exterior painting around the things that decide how long the finish lasts: substrate condition, prep, weather windows, and the products that suit the surface. Houses, trim, shutters, doors, and porches are all part of the scope.
- Wash + prepScrape, sand, caulk, prime
- Weather-awareCoats planned to conditions
- 5-yearWorkmanship warranty
- Lead-SafeCertified for older homes

What exterior work includes
Surface prep
Washing, scraping, sanding, caulking, and spot-priming so the finish bonds instead of peeling early.
Carpentry review
We flag rot, failed trim, and moisture concerns before paint, so repairs happen in the right order.
Color and sheen
Guidance for siding, trim, shutters, doors, and porches that holds up against sun and weather.
Clean transitions
Careful work around windows, trim, and masonry edges where exterior jobs usually look rushed.
How exterior projects run
Condition review
We assess peeling areas, trim, moisture, lead-safe needs for older homes, and access.
Written estimate
Prep, carpentry, and finish are separated so the plan is clear before the crew mobilizes.
Prep then paint
The surface is washed and prepped first; coats are scheduled around weather windows, not a fixed paint day.
Final walk
We review trim, edges, and touch-ups together and confirm the workmanship warranty terms.
Why prep beats a fast paint day
An exterior finish fails from the surface up. Prep quality, the right primer, and clean transitions around trim and windows matter far more than how quickly the color goes on. Painting over a surface that was not ready is how a house ends up repainted years too soon.

Exterior painting questions
What if there is rot or failed trim?
We flag carpentry concerns during the estimate so repairs happen before paint. Painting over failed wood only hides the problem.
How do you handle weather?
Coats are scheduled to real conditions and surface readiness rather than a fixed calendar date, which protects the finish.
Do older homes need special handling?
Yes. Homes built before 1978 are treated with EPA Lead-Safe practices, and we plan prep around those requirements.
