"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."

"Angel and Andrew did a great job on raising the concrete on my patio. One side was sinking which caused the other side to lift up. They were able to even out the cement so now it looks great. Thank you for working so hard to fix it."

"I bought the Big Deal which was just for a single top coat to reseal the deck surface.  However, my deck was in a little bit worse shape than the deal allowed.  However, Ryan was awesome and added in sanding and then did the reseal for no additional charge.  The surface is not perfect but that is due to the rough pre-condition it was in and not his fault.  Shortly after the reseal the deck drains started leaking in to the garage below.  Ryan and crew came out again to fix the drain at no additional cost.  Again, this was not in the deal I bought but they provide such great customer service.  I would definitely use them again and will recommend them to friends and neighbors!

"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."

"The whole process was very smooth. They came out and spent a couple of hours assessing the problems...turns out we had several. The water heater burner had failed and was under warranty. But they also discovered our pressure regulator had failed, our gate valve was frozen, and we had a pipe leaking in the wall! They found the necessary part for the warranty repair and drove 50 miles each way to get it rather than make us wait 1-2 days for for the part to be shipped. They stayed until all the problems were resolved which was greatly appreciated! (My wife and three daughters were not relishing cold showers!)"

"The plumbers were very knowledgeable and quickly figured out the problem with the faucet installation and how to fix it. They also spotted that the “new” faucet contained parts that had been used before, and we got the store to provide new replacements for them."

Basement Waterproofing FAQs, answered by experts

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.
