Our exterior painting process starts with a full inspection and color consult, then an itemized proposal. We wash, scrape, sand, repair carpentry, caulk, and mask. Premium acrylic finishes are applied in two coats within proper weather windows. We specify primers by substrate, schedule seasonally, then walkthrough with you and back workmanship with a written warranty.

Step 1: Inspection and Color Consultation

We start by walking every elevation: checking for peeling, chalking, mildew, failed caulk, and rotted trim, and noting which surfaces need the most preparation. Then comes the fun part — colors. We provide large-format samples and can reference your siding, roof, and stone tones so body, trim, and accent colors work together. Sun exposure matters too: south and west faces fade fastest and influence product selection.

Step 2: The Detailed Proposal

Your estimate itemizes everything: washing, square footage of scraping and sanding expected, priming, linear feet of caulking, carpentry repairs, the exact product lines and number of coats, and masking/protection. Prep is where cut-rate bids hide their shortcuts — an itemized proposal lets you compare bids honestly, line by line.

Step 3: Washing

Paint cannot bond to dirt, chalk, or mildew. Every project starts with a thorough power wash using appropriate pressure for the substrate, plus mildewcide treatment where growth is present. Surfaces then dry fully — typically 24-48 hours — before any coating is applied.

Step 4: Scraping, Sanding, and Carpentry Repairs

Failed paint is scraped and feather-sanded to sound edges. This is the slowest, least glamorous, and single most important step of the entire project: paint applied over loose paint fails with it. Rotted fascia, window trim, brickmould, and damaged siding are replaced by our own carpenters — no separate contractor to coordinate — and all bare wood is spot-primed with the correct primer for the substrate.

Step 5: Caulking and Masking

We re-caulk failed joints at trim, windows, doors, and penetrations with high-performance elastomeric sealant that flexes through extreme seasonal temperature swings. Windows, fixtures, roofing, concrete, and plantings are masked and covered — a clean job site is the visible sign of a careful crew.

Step 6: Application

Finish coats are premium 100% acrylic products from Sherwin-Williams or Benjamin Moore, applied by spray-and-back-roll or brush as the surface demands, within the manufacturer's temperature and humidity windows. Two finish coats are our standard on body colors. In our northern painting season — roughly May through October — application timing matters, and we schedule around weather rather than pushing through it.

Step 7: Walkthrough and Warranty

We walk every elevation with you at completion, touch up anything you flag, and leave you labeled touch-up paint for each color. Your project is backed by Weatherguard's written workmanship warranty against peeling and adhesion failure, alongside the paint manufacturer's product warranty.

Choosing Products by Substrate

Different exteriors demand different systems. Engineered wood like LP SmartSide takes 100% acrylic topcoats beautifully over its factory-primed surface. Cedar and redwood need stain-blocking primers to stop tannin bleed-through. Previously painted vinyl requires vinyl-safe colors that won't absorb heat and warp panels. Stucco and fiber cement call for masonry-rated primers and elastomeric-friendly caulking at joints. Our estimators specify the exact primer and topcoat system for each substrate on your home in the proposal, so the coating chemistry matches the surface it has to protect.

Why Prep Discipline Pays

In a freeze-thaw climate, the difference between a paint job that fails at year three and one still crisp at year ten is almost entirely preparation and product quality. That's why our proposals itemize prep instead of burying it — and why we'd rather lose a bid than skip the steps that make the finish last.

FAQ

Frequently Asked Questions

How long does an exterior paint job take?

Most homes take 3-6 working days: washing and drying, prep and repairs, caulking and masking, then two finish coats. Large homes or heavy-prep projects can run longer. Weather windows are respected — rushing application ruins longevity.

What prep work is included?

Power washing, mildew treatment, scraping and feather-sanding failed paint, spot-priming bare wood, carpentry repairs, re-caulking failed joints, and full masking. Every prep item is itemized in your proposal so you can compare bids honestly.

Do you repair rotted wood before painting?

Yes — our own carpenters replace rotted fascia, trim, brickmould, and damaged siding as part of the project, then prime all bare wood before finish coats. You never need to coordinate a separate contractor.

What paint does Weatherguard use?

Premium 100% acrylic exterior products from Sherwin-Williams and Benjamin Moore, selected for the substrate and exposure. These formulations flex through extreme temperature swings and resist fading far better than builder-grade paint.

How many coats do you apply?

Two finish coats on body colors is our standard, over spot-priming (or full priming where the surface requires it). One-coat 'paint and primer' shortcuts don't survive northern freeze-thaw cycles.

When can exterior painting be done?

The season runs roughly May through October, when surface temperatures stay within manufacturer application windows. Premium products can extend the season slightly, and booking in late winter secures the best dates.

How long will the paint job last?

With disciplined prep and premium acrylic paint, expect 8-12 years on siding and 6-10 on trim and high-sun exposures — roughly double the life of a low-prep, builder-grade job.

Is the work warrantied?

Yes. Weatherguard provides a written workmanship warranty against peeling and adhesion failure, alongside the paint manufacturer's product warranty, and we leave labeled touch-up paint for every color used.
