"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

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.

Home improvement grants are available for various groups, including individuals with very low-income housing, elderly people, older adults, and veterans. These grants can cover a range of needs, from accessibility modifications to addressing critical issues that may affect a resident's health or safety.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

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. 

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.
