"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

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Yes, a crawl space can add value to your home. However, there is a higher chance of it adding value if it is an enclosed crawl space, as this reduces issues caused by excess moisture in the home. That being said, a basement does add more value than a crawl space.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.
