"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."

"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

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

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.
