"The work was excellent. The project was completed in the exact time frame that I was told when I hired them. I had numerous estimates given and M&W charged me a third of what had been quoted by other contractors. AND THEY QUOTED ME FIRST. They were also kind enough to work in a few other small projects I hadnt previously planned. The owner William is very professional and his crew is as well. They did a wonderful job and I will definitely call them first before any other contractor when I'm ready for more work in the future!"

Basement Waterproofing FAQs, answered by experts

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 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.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option. 

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.
