Painting in Houston

Houston is a difficult painting climate for reasons that are not obvious. It is not the heat alone; it is the combination of heat, relentless humidity, intense UV and a thunderstorm pattern that gives you a narrow reliable window to get a coating on and cured.

Mildew Is the Defining Problem

Houston's humidity supports mildew growth on virtually any exterior surface. It shows as black or grey streaking, worst on north elevations, under eaves, and anywhere shaded by trees.

Two things must happen, in order:

1. Kill the growth. Pressure washing alone knocks off the surface layer and leaves the hyphae in the substrate, where it grows back through the new paint within a year. A bleach solution or a proprietary oxygenated cleaner, dwelling long enough to work, is what actually kills it.
2. Use a coating with a real mildewcide package. Premium exterior acrylics carry substantially more mildewcide than economy lines. This is one of the places where the price difference between product tiers genuinely buys something in Houston.

Homeowners often ask for mildewcide additive to be mixed in at the store. It works, but it is a supplement to a good base product, not a substitute for one.

The Weather Window

Two constraints define when exterior work can happen:

• Surface temperature. Most acrylics specify a maximum surface temperature, commonly around 90°F. A sunlit Houston wall in July reaches 130°F and above. Paint applied to it flashes off before it can flow out and bond, leaving lap marks and poor adhesion.
• Dew point and rain. Applying paint in the afternoon before a surface drops below dew point overnight causes surfactant leaching, which shows as brown or tan streaks. Afternoon thunderstorms in summer wash uncured coating off entirely.

The practical seasons are late October to early December, and March to early May. Summer work is possible if the crew follows the shade around the house, starting on the east elevation in the morning and finishing on the west in the evening. Ask any bidder how they plan to sequence a summer job. A good answer tells you a lot.

Hardboard Siding

A very large share of Houston housing built between roughly 1975 and 1995 has hardboard composite siding — Masonite and similar products. In this climate it fails predictably.

• Swelling and delamination at the bottom edge of boards, where water sits.
• Soft, punky material that will not hold a fastener or a coating.
• Failure at the butt joints and around window openings.

Paint will not save a failed board. It has to be replaced. This is the most common reason a Houston exterior painting quote comes in above expectation, and it is the most common thing a cheap quote leaves out. Ask explicitly whether the bid includes siding repair, how it is priced, and what happens if more damage is found once work begins.

Where hardboard is sound, the critical detail is sealing every cut edge and butt joint, and keeping the bottom course clear of grade and mulch.

UV and Colour Retention

Houston's UV load fades deep colours quickly, particularly reds, dark blues and dark greens on south and west elevations.

• Choose 100% acrylic products over vinyl-acrylic blends.
• Prefer inorganic pigments in deep colours; the manufacturer can advise which of their bases hold up.
• Expect south and west elevations to need attention on a shorter cycle than the rest of the house. Refreshing two elevations at year six is far cheaper than repainting all four at year eight.

Interior Considerations

Houston interiors have their own humidity issues:

• Bathrooms and laundry rooms need a coating with mildewcide and, more importantly, a working exhaust fan vented to the outside rather than into the attic. Venting a bath fan into the attic is common in older Houston homes and it causes mould above the ceiling.
• Closets and exterior-wall corners in an under-conditioned house can grow mildew. That is a humidity control problem, not a paint problem.
• New drywall should have a dedicated drywall primer; wall paint used as primer over new board gives uneven sheen.

Tips for Houston Homeowners

1. Kill mildew, do not just wash it. This is the single most common Houston paint failure.
2. Ask what the bid assumes about siding repair before signing anything.
3. Schedule for the shoulder seasons and book early, because so does everyone else.
4. Buy the premium exterior line. The mildewcide difference is real here.
5. Check that bath fans vent outside, not into the attic, while you have a contractor in the house.
