Stucco exteriors around the Ranchos in Portola Valley, CA sometimes start cracking while others look solid year after year. The condition of stucco depends on timing and understanding our unique microclimate here in Portola Valley, CA. Heavy moisture rolls off the hills in winter, and dry heat bakes west-facing walls in August. Stucco takes a beating from these weather patterns. Homeowners planning any Stucco work or trying to keep their Stucco in good shape must work with the weather.
Timing Your Stucco Work Around Our Climate
Stucco work cannot be applied to a wall whenever it fits a calendar. Temperature and humidity dictate everything for Stucco. Here in the valley, crisp and foggy mornings are followed by warm afternoons, especially closer to the open space preserves. If the temperature drops too low at night while the Stucco material is curing, moisture gets trapped inside the mix. Trapped moisture leads to weak spots and premature crumbling in Stucco.
Late spring through early fall is the best time for any major Stucco application. The air is dry, the rain has stopped for the most part, and Stucco walls have time to cure properly without baking too fast in extreme heat. When the temperature is over ninety degrees, water evaporates out of the fresh Stucco coat way too quickly, robbing the cement of the strength it needs. Neighborly Stucco always checks the upcoming week's forecast before scheduling anything outdoors for Stucco work in Portola Valley, CA.
Protecting Your Investment Through the Wet Months
Winter brings its own set of challenges for Stucco in Portola Valley, CA. Seasonal rain hits our sloping lots and works its way down, putting pressure on retaining walls and lower sections of your house. Water is the absolute enemy of traditional lath and plaster Stucco. Check your flashings and make sure your gutters are not dumping overflow directly against the base of your Stucco walls. Preventative sealing around windows and trim goes a long way before the first big storm hits.
- Walk your perimeter after a heavy rain and look for dark, damp patches that stay wet too long on your Stucco.
- Keep landscaping shrubs trimmed at least a foot away from the Stucco walls so air can circulate and dry out the surface.
- Address hairline cracks immediately in your Stucco before winter rains turn them into deep fractures.
Year-Round Maintenance Routine
Homeowners do not need a complicated checklist to keep their exterior Stucco healthy. Once a season, take a garden hose with a gentle nozzle and rinse off the dust and pollen that collects on Stucco, especially under roof overhangs. Avoid high-pressure washers because they can easily gouge the Stucco finish coat or force water right through minute gaps. If you notice a strange powdery residue or small chips falling off your Stucco, give Neighborly Stucco a call. Catching small issues early means you avoid major structural repairs down the road, keeping your Portola Valley home looking sharp for 15 to 20 years or more.
