"I have a very old house and the basement drain has clogged twice in the past two and a half years.
The first time the clog left two inches of water on the floor. Noah Ball came the same day I called and flushed the drainpipe.
He also gave me tips on how to try to keep the drain clear.
Two years later he had to come back for the same reason, although the damage wasn't as bad. This time it was determined that there were roots in the pipe; he cleared it and we have discussed what my next steps will be. At some point the line will have to be repaired or replaced, but prior to that he will do a TV scope to get to the specifics of the problem.
I was very impressed with Noah. He is professional but easy to talk to - and appears to be sincerely interested in doing the best job possible at a reasonable price. I wouldn't think of using another company for rooting. AND, in both cases, he came the same day I called. Now that's good customer service!

"Shane was very responsive and knowledgeable to address the humidity problem in the crawl space and odor being emitted through the vents. His team of professionals installed a dehumidifier, replaced the vapor barrier, and sealed the vents. I'd highly recommend MSG team of professionals for your next repair project ."

"Insulating a crawl space is incredibly expensive (especially for a space that hardly anybody ever sees or goes into), but they did a good job and it has helped in keeping the pipes warmer in winter and reducing damp feeling inside the house."

"Nearly three years ago, I asked JES to install a waterproofing system around my basement (in 2016). After they did this, there was no further flooding or leaking of ground water into my basement. In addition, the dehumidifier makes the whole house smell fresh."

Basement Waterproofing FAQs, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

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.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.
