"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

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.
