"Excellent! I could not have asked for a better crew. JT, Shaun, Pedro and Kayla were my direct contacts and all were very professional. Western Pacific Roofing came to the rescue just before this last big rain. They were not prepared to repair my roof upon first observation, however, they were able to secure the exposed area so as not to allow further damage from the impending rain storms. We survived the rain, they returned the next business day after the rains. Roof is repaired and I’m completely satisfied with my overall experience. Western Pacific Roofing has become my go to company for all of my properties’ roofing needs..."

Basement Waterproofing FAQs, answered by experts

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.
