"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"Stephen and Wendel's crew at Key Waterproofing Construction did an excellent job in waterproofing my basement with cement. They were extremely professional, and superfast. Completed the job in five hours, had a crew of six, to completed a foundation of 200 sq ft. The price was right and job was impeccable, crew left the site nice and clean."

"Our experience with DryCrete Waterproofing was excellent, 5 Stars. The basement flooded twice this past fall and spring prompting our search for a solution. This company provided everything covered in the quote, to the letter and exact price. I would recommend them to my family or friends."

"This business was professional, communicative, and on time from my initial inquiry to when the job was performed. When I initially called, they were able to get someone out to provide a quote within 2 weeks and had me booked within another couple weeks. I was provided a quote online, and that's what I ended up paying. No fine print. Everything was completely transparent. William and another person came to do the actual sump pump installation. They were on time and finished a rather challenging installation (the pipe exit needed to be in a different room than the actual pump) within 4 hours or so. He explained everything to me clearly and was friendly, courteous, and professional. I would absolutely recommend these guys if you're looking for any kind of basement repair/waterproofing."

"I hired Beantown Strong Construction for a shingle roof replacement and gutter drainage work, and the results were amazing. William and Tony worked very professionally and kept everything clean throughout the project. The new roof looks strong and perfectly installed. Their attention to detail really impressed me. Highly recommend them for roofing services and drainage solutions."

"We hired Leal Restoration to clean up water damage on three floors of our house. They came early on a Saturday morning, worked all weekend and finished the job on Monday. This included drying out the area, removing debris, and replacing a ceiling. The work was done efficiently and carefully. Leal turned a disaster area into a clean and back to normal living space in 3 days. Amazing!"

"Took waaaay to long. 6 months, albeit, we started in late November but it was the nicest winter in history. Promise was late February for completion. I finally conceded in June that they had finally met all contractual obligations. There were several reasons it took so long from my point of view: not showing up when they say they are, poor workmanship requiring lots of rework (all caught by me, not the so called Project Manager), no dedicated project manager, unclear instructions/requirements flowed down to the contractors sent to do the work, company too focused on the next jobs instead of completing this one, etc..I could go on and on...Damaged my driveway and blamed the driveway even though I asked upfront if there would be any harm to it. "No we do this all the time" was the response. Damaged my neighbors lawn and I'm still fixing that. Overall, a bad experience. I'd rate them a "D" but they did eventually fix most of the quality problems. The rest I have, or will take care of. Cutting the ties with this contractor. Would not recommend."

"We have been getting water in our basement since we moved here a couple years ago. This last time was the worst. Inner Boston came Take a look and figure out the issue. Were very quick to come in and give me a solid estimate. They walked me around the house showed me and explained in detail what the issue was and what needed to be done to ensure that we no longer got water in the basement. They saw that not so great weather was coming up so they came in and got the work done within just a couple days. I mostly spoke with Mark but all super nice and so great to deal with! Iâ m so glad that we chose them to do the job. Highly recommend!"

Basement Waterproofing questions, answered by experts

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

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.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.
