Getting stucco ready before monsoon season

Monsoon rain in New Mexico does not arrive gently. It comes in short, heavy bursts, often driven sideways by wind, and it finds gaps that ordinary rainfall never would. Most of the stucco damage that shows up afterwards was not caused by the storm so much as revealed by it. A walk around the house before the season costs nothing and is worth doing.

Start at the top

If your home has a flat roof with parapet walls, the caps along the top of those walls take more weather than anything else on the building. You will not see a failing cap from the ground. What you will see is cracking or staining concentrated near the top of a wall below the roofline, sometimes appearing on a stretch that looks unrelated. Treat that as a reason to have the cap checked rather than to patch the wall.

Check every opening

Windows, doors, vents, hose bibs, light fixtures, and anywhere a pipe or cable passes through the wall are the places wind-driven rain gets in. Look for gaps where the stucco meets trim or frame, and for sealant that has hardened, shrunk, cracked, or pulled away. These are small, cheap things to put right before a storm and expensive to ignore afterwards.

Follow the water down

Look at where roof runoff actually lands. A downspout discharging against a wall, or splashing off a hard surface onto the base of one, will work on that stucco every storm. The same is true of irrigation that sprays the same patch of wall daily. Damage low on a wall very often traces back to water that is being aimed at it rather than to the stucco itself.

Note anything that changed

Compare what you are seeing with what you remember. A crack that has widened, a stain that has appeared, a patch that has started to feel soft, or paint or finish beginning to lift are all worth writing down. If a contractor does come out, that history is genuinely useful, and it is easy to forget by the time anyone arrives.

If the walk-around turns something up

Describe what you found in the quote form, including which wall and where on the home. A local contractor will follow up to arrange a look. Going into the season with sealed openings and a sound cap is a much cheaper position than coming out of it with water behind the finish.
