"Anyone who has waterproofing needs should hire Bill and his team. They are fantastic. I am the President of our HOA ( 5 townhome building) and a resident in one of the 5 units. The building had a number of areas in our underground common area and one resident's garage in particular where water was draining from outside of the foundation of the building. There were no less than 4 separate areas where water was entering the interior of the building. Of all the contractors we interviewed for the job, Bill was the most honest, practical, thoughtful and analytical in his approach to the job. He was more like a surgeon carefully dissecting the problem and then fixing the issues, one a time rather than what most of the other contractors wanted to do, which was tear up the east side of the building and "we'll then see what the problem is." He and his team showed up everyday they said they would - on time. They worked hard and cleaned up their work area every time they were there. He tested his work (flooding areas and letting the water sit for 48+ hours) to make sure he had done the job right and completely. He explained what he was going to do and then he did it. I highly, highly recommend 21st Century Waterproofing. One of the best contractors I have ever hired - for ANY JOB - in my 30+ years of managing properties."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"After the large windstorm we had here in Lancaster, CA my roof suffered some major wind damage. I called them and they set me up with someone to quote us for the job. The price seemed fair and once I had signed the contract they scheduled the repair for the end of the week. The work was done well, and the employees were very professional. I was pleased with their punctuality, and the fact that they cleaned up after themselves. I would recommend Western Pacific Roofing Corp. to all my friends and family. my rof."

Basement Waterproofing questions, answered by experts

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.
