Great paint jobs start long before the first brush stroke. If you want to know how to prepare a house for exterior painting in MA, the answer is simple: clean it, repair it, and protect it. Skip those steps and even the best paint will peel early. Since 1972, Painters Etcetera, one of the trusted exterior painting contractors in Massachusetts, has prepped and painted homes across the state. Here are the eight steps our crews follow, plus what you can do yourself before the painters arrive.
Why You Should Prepare a House for Exterior Painting in MA
New England weather is hard on paint. Humid summers, heavy snow, and freeze-thaw cycles push moisture into wood and cracks. Paint applied over dirt, mildew, or loose old paint cannot grip the surface. It blisters and peels, often within a few seasons. With proper prep and quality paint, an exterior finish can last 7 to 10 years. Prep decides which end of that range you get.
How to Prepare a House for Exterior Painting: 8 Steps
1. Choose the Right Weather Window
Late spring through early fall, roughly May through October, is the best time to paint in Massachusetts. Most exterior paints need air and surface temperatures above 50°F, so check the label on your can. Avoid days with rain in the forecast and mornings with heavy dew. Wet surfaces trap moisture under the paint.
2. Check for Lead Paint First
If your home was built before 1978, the old paint may contain lead. Do not dry-sand or scrape it without a plan. The EPA’s Renovation, Repair and Painting rule sets lead-safe work rules for paid work on older homes. Ask any painter how they handle lead-safe prep before you hire.
3. Wash the Exterior
Dirt, chalk, and mildew block paint from bonding. Wash siding with a mildew cleaner and a soft brush, or use a low-pressure washer. High pressure can gouge wood and force water behind siding. Let the house dry fully, often 24 to 48 hours, before moving on. Read our guide on what to pressure wash before painting for more detail.
4. Scrape and Sand
Scrape off every bit of loose, peeling, or bubbling paint. Then sand the edges so they blend smoothly into the sound paint around them. Paint applied over a rough edge shows every ridge. Lightly sand glossy areas so the new coat can grip.
5. Repair Damaged Wood and Surfaces
Probe trim, sills, and corners with a screwdriver. Soft wood means rot. Replace rotted boards or fill small areas with exterior wood filler. Set popped nails and patch cracks and holes. Skipping repairs only paints over a problem that will come back.
6. Caulk Gaps and Joints
Seal gaps around windows, doors, trim, and corners with paintable exterior caulk. This keeps water out of the wall. Never caulk over wet or dirty surfaces. Let the caulk cure as the product label says before you paint.
7. Prime Bare Wood and Stains
Spot-prime any bare wood, repaired areas, and stains. Primer seals the surface and helps the topcoat look even. Without it, patches show through as dull or blotchy spots. A stain-blocking primer also helps with water marks and tannin bleed from cedar.
8. Protect Plants, Windows, and Surroundings
Trim back shrubs so painters can reach the walls. Cover plants and walkways with drop cloths. Move patio furniture and grills away from the house. Mask windows, light fixtures, and hardware. Good protection also keeps the job site clean.
What Professionals Check Before the First Coat
Homeowners can handle some prep. A trained eye catches the hidden problems. After more than 50 years of painting, our crews know where Massachusetts homes tend to fail: under window sills, along trim ends, and on shaded walls that stay damp. We also test how well old paint is holding on, and we match primer and paint to your siding. That is why prep is never an add-on with professional exterior painting from Painters Etcetera. It is built into every job.
When to Hire Pros to Prepare Your House for Painting
DIY prep can work on a small home with newer paint. Hire a pro if your home is tall, has peeling or rotted areas, or was built before 1978. Licensed painters bring the right equipment, insurance, and safe-work practices. Painters Etcetera is licensed in Massachusetts (HIC# 195388) and insured, and every exterior job carries a 3-year workmanship guarantee.
