Stucco Repair & Painting in the Phoenix Area

Stucco repair is the first half of every exterior repaint we do in the Phoenix area. The order matters more than the paint: pressure wash, elastomeric patch on the hairline cracks, re-stucco wherever the finish has let go, Loxon conditioner, then two coats of 100% acrylic sprayed and back-rolled into the texture. Skip a step and the cracks come back through the new paint in a season.

I’m Robert, the owner of Maricopa Valley Painting in Mesa. Stucco is most of what we paint, across more than 3,300 projects in the Valley since 2020. Here’s exactly what we do to it, and what we don’t.

How we repair stucco before painting

1. Pressure wash. Chalk, dust and the loose edges of the old paint come off first. Patching over chalk is patching over dust. Skipping the wash is the single biggest mistake I see on other painters’ work.

2. Elastomeric patch on hairline cracks. Small cracks get filled with an elastomeric patching compound. It stays flexible, so when the wall moves in our heat the patch moves with it instead of splitting. We use the same product to fill imperfections in sun- or water-damaged wood on fascia and pop-outs.

3. Re-stucco where it’s flaking. Where stucco is hollow, lifting or crumbling, a patch won’t hold. That section is cut back to sound material, re-stuccoed and retextured to match the wall. You’ll find this most at the bottom few inches of a wall where sprinklers hit, under roof drip lines, around hose bibs and electrical boxes, and on south and west walls.

4. Loxon conditioner. On all the stucco, especially where the old paint is faded or chalky. It binds what’s left of the old surface and gives the new paint something to grip.

5. Re-caulk windows and doors. A standard step on every job.

6. Two coats, sprayed and back-rolled. The back-roll pushes paint into the texture instead of leaving it on top. Two coats is our standard; a dark-to-light color change usually takes more, and every coat it takes is in the quote.

All of it is itemized on the quote before you sign, so you can see what your walls need and what it costs. Our guide to hairline vs. real stucco cracks shows how to tell the difference yourself.

What we don’t do: whole-wall elastomeric coatings

You’ll see elastomeric paint recommended for cracked stucco. We use elastomeric for crack fill only. A thick elastomeric skin over a whole house can trap moisture in the wall, it’s difficult to repaint over later, and it doesn’t fix the reason the wall is cracking. On most houses the body coat is Sherwin-Williams Latitude over Loxon conditioner; we also use Duration, A-100 on budget jobs, and Dunn-Edwards Evershield where an HOA requires it. Doors get the same product in semi-gloss.

The cracks a painter shouldn’t fix

Most stucco cracks on Valley homes are hairline: thin, random, the same width year after year. Those we patch and paint. A straight diagonal crack from the corner of a window, door or garage opening that’s wide enough to take a business card, stair-step cracks along block courses, or a crack that keeps growing after you mark it mean the wall is moving. We’ll point those out at the estimate and suggest a stucco or foundation contractor look before we paint, so we paint it once.

Is it time?

• Hairline or spiderweb cracks showing through the paint
• Chalky white powder on your hand when you rub the wall
• Faded or blotchy color, worst on the south and west walls
• Paint bubbling or lifting at the base of the wall
• White, powdery streaks after monsoon rain (salts pushed out by water moving through the wall)
• Stucco that sounds hollow when you tap it, or lifts at the edge of a crack

After a wet monsoon, “new” cracks usually aren’t new; the wall dried unevenly and the hairline cracks showed up. What is worth checking is where the water is getting in, because that’s where the prep needs to go. We don’t paint on monsoon days, and after rain we wait until the following day.

What it costs and how long it takes

Stucco repair is part of a full exterior repaint and is itemized on the quote. In 2026 a typical single-story home generally runs $3,000 to $4,500 and a two-story home $4,500 to $8,000 in the Phoenix area; a house with heavy stucco repair lands toward the top of its range. The full breakdown is in our exterior painting cost guide.

A typical exterior takes about three days: wash, cover and repair on day one; finish repairs and start painting on day two; second coat, fascia by hand, clean-up and a walk-through with you on day three. We’re usually about ten days out year-round, a little longer in spring. Fall (October through November) and spring (February through April) are the two good windows; the month-by-month version is in our exterior painting calendar.
