Stucco Repair St. George
Preventative Care

How to protect and maintain your stucco in the St. George sun.

Stucco is durable, but Southern Utah's intense UV rays, fluctuating temperatures, and dry climate can stress the finish. Consistent, simple maintenance can prevent small issues from turning into expensive wall repairs.

Seasonal Stucco Maintenance

Your exterior takes a beating from the elements year-round. Taking a proactive approach every spring and fall ensures the protective skin on your home stays intact.

Safe Washing: Dust and dirt build up on textured surfaces. Gently wash your walls once or twice a year using a low-pressure garden hose. Never use high-pressure power washing on stucco, as it can blast the finish right off the wall or force water deep into micro-cracks.

Irrigation Control: One of the biggest enemies of stucco in Washington County is chronic overspray from sprinklers. Make sure sprinkler heads are directed away from the base of the walls. Constant moisture will cause efflorescence (white, chalky stains) and eventually weaken the underlying material and framing.

Inspect Windows & Doors

The sealants around your windows and doors expand and contract and eventually dry out in the sun. Replace old, cracked caulk to prevent water from intruding behind the stucco skin.

Clear the Weep Screed

The metal edge at the bottom of your stucco wall is the weep screed. It allows trapped moisture to drain. Keep dirt, rock, and mulch several inches below this line so the wall can breathe.

Monitor Hairline Cracks

Not every crack is an emergency. Keep an eye on small hairline cracks (less than 1/16 inch). If they start growing or multiplying into a spiderweb pattern, it's time to call a professional.

When to call a professional

Routine washing and checking caulking are easy DIY tasks. However, if you spot any of the following, you need a professional repair scope:

Common questions

How often should I wash my stucco in St. George?

It's best to gently wash your stucco 1-2 times a year to remove desert dust, debris, and prevent staining. Avoid high-pressure washing which can damage the finish.

How do I know if a crack needs immediate repair?

If a crack is wider than a credit card (about 1/16 inch), if it runs diagonally from a window or door corner, or if you see signs of moisture around it, you should have it professionally inspected and patched.

Can irrigation damage my stucco walls?

Yes. Constant overspray from sprinklers can saturate the lower portions of stucco, leading to efflorescence (white salt deposits), cracking, and long-term water damage to the underlying sheathing.
