"I have a mid century home with a concrete floor. I had multiple settling points and voids underneath the team at saber got it stabilized and leveled in a matter of hours. They were prompt, kept everything clean, and did everything I was expecting and hoping for."

"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!

"I recently hired JP Plumbing to address a clogged main line drain and the experience was exceptional. John (JP), the technician, provided outstanding service from start to finish. He was punctual, arriving right on time and ready to tackle the issue. John’s honesty and transparency really stood out. He took the time to explain the problem in detail and even went the extra mile by attaching a camera to inspect the pipes. He showed me exactly where the issues were occurring, giving me peace of mind and confidence in the work he was doing. What truly impressed me was his dedication to going above and beyond. Not only did he resolve the clog efficiently, but he also provided helpful maintenance tips to prevent future issues and keep my drains running smoothly. If you’re looking for a professional who truly cares about quality and customer satisfaction, I can’t recommend John (JP) and JP Plumbing enough. This is the kind of service everyone hopes for when hiring a plumber—professional, thorough, and completely trustworthy."

Basement Waterproofing FAQs, answered by experts

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

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.

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.
