Executive Summary: Metal Siding Painting Houston
Metal siding painting in Houston cleans, rust-treats, primes and repaints metal siding, fascia, flashing and trim.
Metal gets rust-inhibiting bonding primer + topcoat with 2 coats of exterior acrylic over an estimated 2 to 7 days, handled by a 3 to 6 painter crew. Houston-area work typically costs $2 to $4.50 per square foot, or $4,000 to $9,000 for 2,000 sq ft of surface (estimates).
Rain stops primer work on bare metal, and loose panels need fixing before paint. Pre-1978 buildings need lead paint testing before scraping.

Stop Letting Fading & Damage Hurt Your Property Value
Paint peeling off smooth metal
Paint will not stick to glossy or galvanized metal without the right primer. We scuff-sand and use a bonding primer made for metal.
Rust spreading under paint
Rust keeps growing under new paint if it is not removed. We wire-brush to sound metal and prime with a rust-inhibiting primer the same day.
Chalky, faded factory finish
Houston sun breaks down factory coatings into chalk. We wash it off before primer so the new coat bonds.
Schedule a Walkthrough
We check every panel and trim run for rust, chalk and loose fasteners. The written estimate lists prep, primer and coats by area.
Our Process: Done Right the First Time
- 1Detailed Estimate & Color ConsultationWe look at every panel, fastener and trim run, note rust and loose sealant, and confirm color with you. Older painted metal gets lead testing if it predates 1978.
- 2Expert Prep & PaintingMetal gets washed, rust gets wire-brushed and treated, and glossy areas get scuff-sanded. Bonding primer goes on bare metal the same day, then 2 coats.
- 3Final Walkthrough & Clean-UpWe walk the building with you and recheck any rust spots we treated. Wire-brush dust and masking come off before we leave.
What to Expect: Your Project Timeline
| Stage | When | What Happens |
|---|---|---|
| Estimate & booking | 1 to 2 weeks ahead | Panel-by-panel rust check and written estimate |
| Prep day | Day 1 | Wash, rust treatment, scuff-sanding, bonding primer the same day |
| Paint application | Days 2 to 5 | 2 coats, shaded sides first in summer |
| Dry & walkthrough | Final day | Rust-spot recheck and touch-ups |
| Curing | First few weeks | Coating hardens; avoid pressure washing the panels |
These are estimates. Rain or heavy rust can add a day.
The Right Time to Schedule Metal Siding Painting Houston
You see rust spots.
Treat rust while it is on the surface. Once it eats through, panels need replacing.
Paint is flaking off.
That usually means no primer was used. A proper system fixes it.
Wood trim is on the same house.
Paint both in one visit; see Wood Siding Exterior Painting.
Avoiding Peak Heat
Metal painting runs best from March to May and September to November. In summer we start early and paint shaded sides first.

Frequently Asked Questions
Yes, we do. Metal siding usually needs washing, rust treatment, a rust-inhibiting bonding primer and a UV-resistant topcoat. Skipping the primer is the main reason paint peels off metal. Loose panels and failed sealant need fixing first, because paint will not hold them in place.
Metal gates and railings follow the same system; see Fence & Gate Painting Services.
The short answer is about $2 to $4.50 per square foot of paintable surface, or roughly $4,000 to $9,000 for a 2,000 sq ft home, based on typical Houston-area pricing. Square footage, stories, siding type and repairs move the number. Your written estimate sets the exact price.
Two-story metal buildings cost more per square foot because of lift time. Heavy rust treatment adds labor.
Metal siding painting usually requires a wash to remove chalk and dirt, wire-brushing or sanding rust to sound metal, treating rust spots, scuff-sanding glossy factory finish, fixing loose panels and failed sealant, then a rust-inhibiting bonding primer on bare metal the same day before the topcoat.
Galvanized metal needs a primer made for it, or paint will flake.
The short answer is several years for a properly primed acrylic system on metal, and longer for lighter colors that absorb less heat. Dark colors on south and west walls fade and chalk faster. Rust left under the paint is the main cause of early failure.
Metal gets hot enough in Houston summer to blister paint applied in direct afternoon sun, so we paint shaded sides first.
The short answer is rust is wire brushed or sanded back to sound metal, then spot-primed before the finish coats. Painting over active rust lifts the new coat within a season. Any panel that has rusted all the way through is a repair, not a paint job.
We point out panels in that condition at the walkthrough so they are not a surprise mid-job.
