"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."

"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!)"

"On Thursday, Cesar gave me an estimate. Since it was a very reasonable price (based on another estimate I got) I decided to call them back Friday morning to schedule and appointment. I was pleased they were able to come that afternoon to install the new water heater. Both Cesar and Dylan were very courteous and professional. They answered all my questions and finished the job in a timely manner. I looked at what they did and it looked good and the water heater is working very well."

Basement Waterproofing questions, answered by experts

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
