Cleaning as needed to remove dust, chalking, mildew, or debris
Scraping and sanding loose or failing paint
Spot priming bare wood or exposed substrate
Caulking gaps and seams where appropriate to reduce water intrusion
Repair recommendations for wood rot, damaged boards, or substrate concerns
Masking and covering to keep lines clean and prevent overspray or splatter

Prep is where long-term performance is won. We don’t rush it.

Exterior Painting FAQs

How long does exterior paint typically last?

Longevity depends on surface condition, prep quality, sun exposure, and product selection. During your estimate we’ll explain what to expect based on your home’s materials and condition.

Do you power wash before exterior painting?

Cleaning is often part of proper prep, but the method depends on the surface and condition. The goal is a clean, stable surface that paint can bond to reliably.

Can you paint over old paint?

Yes—if the existing coating is stable. If areas are peeling or failing, those spots must be scraped/sanded and properly primed before repainting.

Will you fix wood rot or damaged boards?

We can include repairs if needed, or we can recommend the best path depending on the extent of the damage. Any repair scope is clearly listed and approved before work begins.
