"Extensive work beneath subfloor required. Peter and Oleg were very responsive and accommodating to our schedule. They worked later than normal to complete the job in one visit. Could not have asked for better service or more friendly, courteous, professionals."

"I had previously used this plumbing company to install new faucets after I had tried to repair on my own. The owner, Mike, came after I found it impossible to complete the job. He worked (in a very cramped space) with difficulty and got the job done. I was so pleased by the service, I called upon him again as we gave the master bathroom a makeover and new faucets were in the plan. We provided the faucets and Mike once again crawled into the small cramped spaces and got the job done. I would normally give the company my highest marks all around, but the item that needs remarking about was the phone communication aspect of the service. Mike was forced to leave after one faucet was completed to address another waiting job (The first faucet was more difficult to remove than anticipated and took much additional time). He said he would return later that night. I felt it unnecessary for him to work at night and agreed for his return the next day. He never showed up and neither he or his office did not call. I called the office and received no call back (his wife takes his office calls). It wasn't until the evening that I heard back and was told that he would be there the next day. He did arrive and I was told of a particularly difficult job that kept him from returning the next day. He has a cell phone. I felt a call back would have gone a long way toward a more satisfactory communication.
As to his work, he is an experienced plumber with a high level of attention to the task at hand. Upon completion, he left us with a high level of satisfaction. On his way out I inquired about some leakage coming from the downstairs toilet that had just begun. He quickly identified the problem. We made a new appointment. He arrived on time and got the job of installing a new seal quickly. Again we were satisfied with his work. On this job, phone issues were not present. I would hire him again without question.

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.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.
