How to Prepare Your Home for Exterior Painting: A Cape Cod Homeowner's Guide

The most important part of any exterior paint job happens before a single brush touches your home. Proper preparation is the difference between a paint job that lasts 8+ years and one that starts peeling in 12 months.

Why Prep Matters on Cape Cod

Cape Cod's coastal environment is brutal on exterior paint. Salt air, humidity, freezing winters, and intense summer sun demand thorough preparation to ensure your paint adheres properly and lasts.

The industry standard: 70% of the work is preparation, 30% is painting.

Step-by-Step Prep Process

1. Inspection and Assessment

Before anything else, we assess:

• Current paint condition (peeling, blistering, chalking)

• Wood rot or damage

• Moisture issues

• Previous paint type (oil-based vs. latex)

2. Power Washing

Every surface gets professionally power washed to remove:

• Dirt, mildew, and algae

• Loose and flaking paint

• Salt residue (critical on Cape Cod)

• Cobwebs and debris

Drying time: 24–48 hours before painting begins

3. Scraping and Sanding

All loose paint must be removed:

• Hand scraping for detailed areas

• Mechanical sanding for large flat surfaces

• Feathering edges where old paint meets bare wood

• Spot sanding glossy surfaces for better adhesion

4. Repairs

Any damage discovered during prep needs fixing:

• Wood rot — Replace damaged boards and trim

• Caulking — Re-caulk all joints, seams, and gaps

• Nail pops — Reset and fill

• Gaps around windows and doors — Seal properly

5. Priming

Raw wood, repaired areas, and transitions need primer:

• Bonding primer for glossy surfaces

• Stain-blocking primer for tannin bleed (common with cedar)

• Rust-inhibitive primer for any metal surfaces

6. Protection

Before paint goes up:

• Cover plants, landscaping, and decks

• Mask windows, doors, and fixtures

• Protect driveways and walkways

• Move outdoor furniture and décor

What Homeowners Can Do to Help

• Trim vegetation — Keep bushes and trees 12+ inches from the house

• Clear the perimeter — Move grills, furniture, and decorations away from walls

• Secure pets — Ensure animals have a safe space away from the work area

• Plan access — Ensure we can reach all sides of your home

• Notify neighbors — Especially in close Cape Cod neighborhoods
