A great exterior paint job is about 70% preparation and 30% painting. The paint itself only lasts as long as the surface underneath it, and in Dallas–Fort Worth, where summer sun, spring storms and the occasional hard freeze all take their turn, skipping prep shows up fast. Whether you plan to hire a crew or tackle part of the work yourself, here is what needs to happen before the first brush touches the siding.
1. Pick the right season and check the forecast
Most exterior paints need temperatures between about 50°F and 90°F, with no rain for at least 24 hours after application. In North Texas, spring (March to May) and fall (September to November) are the sweet spots. In midsummer, we start early and follow the shade around the house, because paint that dries too fast in direct sun can blister and leave lap marks. Avoid painting right before a cold front; overnight dew on fresh paint can leave a cloudy, sticky film.
2. Inspect the whole house
Walk every side of the home and make a list: peeling or chalky paint, soft or rotted wood, cracked caulk, gaps around windows, rust on metal, and mildew on shaded walls. Push a screwdriver gently into suspicious trim; if it sinks in, the wood needs repair or replacement before painting. If you are not sure whether your house is due, our article on the signs your home needs a fresh coat of paint walks through what to look for.
3. Wash every surface
Dust, pollen, cobwebs, chalk and mildew all stop paint from bonding. Every exterior needs a thorough cleaning, and the method matters. Brick and concrete can take higher pressure, while wood siding, Hardie board and older homes need a lower-pressure wash with the right cleaner so water is not forced under the boards. Professional power washing removes the grime without damaging the surface. Then the house needs at least a full day of dry weather before painting.
4. Scrape, sand and repair
All loose and flaking paint has to come off. After scraping, the edges are sanded so the old paint feathers into the bare areas instead of leaving visible ridges. Rotted wood is cut out and replaced or filled with an exterior-grade epoxy, nail heads are set and spotted, and dents or holes in siding are filled. This is the slowest part of the job and the part that most often gets rushed by low bids. It is also the part that decides whether your paint lasts three years or ten.
5. Caulk and seal the gaps
Old caulk that is cracked, shrunken or pulling away is removed and replaced with a high-quality, paintable elastomeric sealant. Focus on window and door trim, corner boards, where siding meets trim, and any penetrations for pipes, vents and wiring. Good caulking keeps water out of the walls, lowers cooling bills and gives the finished job crisp, clean lines.
6. Prime what needs it
Bare wood, repaired areas, new siding, stains and chalky surfaces all need primer. Primer seals the surface, blocks tannin bleed from cedar and redwood, and gives the topcoat something to grip. If you are making a big color change, such as dark to light, a tinted primer saves a coat and helps the new color look even.
7. Choose your colors and paint carefully
Exterior colors look very different in strong Texas sun than they do on a small paper chip. Always test samples on at least two sides of the house and look at them in the morning and afternoon. Think about your roof, brick or stone, and the neighborhood, too. Our post on painting to match your home’s exterior has tips, and a color consultation takes the guesswork out completely. When it comes to the paint, a premium 100% acrylic exterior product is worth the extra cost; it flexes with temperature swings and resists fading.
8. Protect everything that is not being painted
Cover plants, walkways, AC units, light fixtures and vehicles. Trim back shrubs and branches at least a foot from the walls so they do not brush against wet paint, and move patio furniture and grills away from the house. A professional crew handles all of this and cleans up at the end of every day.
