"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."

"I was impressed with his knowledge and professionalism. He installed a French drain system with a vapor barrier on the walls. He prepped the area to protect our belongings, made sure everything was cleaned up after the end of each day, and provided exceptional service and quality. I would highly recommend him!"

"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!"

"Mixed review I had spoken with other radon remediation companies and received quotes before meeting with Erickson Foundation Solutions. The salesman, Chris, seemed much more thorough in his approach and he gave a presentation explaining radon, its danger and the process to remove it. The quote was slightly higher than another quote, but I felt more confident. And with the added fan moisture guard, the system came with a 10-year warranty. So I agreed to the proposed plan and paid a deposit. Later I decided to not install concrete in the adjacent (but not connected) basement/crawl space. I asked Erickson to quote installation of plastic sheeting to seal that space. John, the sales manager’s quote doubled the total price. I already had found durable plastic sheeting for about $300. So how would that become $2000 extra? John explained that there would be a drainage mat under the plastic and it would be attached every few inches to the walls and then sealed with caulking. But besides sealing the area, the quote also included another extraction hole and piping to connect it to the fan. This seemed to me like over-kill for a 1200 square-foot house. But he said without the second extraction location, they would not warranty the job. So I accepted the “up-sell” and signed. Today the office called to tell me when the crew would arrive and they arrived on time and were very pleasant. However, they did not have the drainage mat. They called their supervisor and was told that it was not included in the quote and would be an additional charge. In fact it had been a verbal inclusion, not written. The crew was surprised that a second extraction hole was quoted, since the radon levels were not very high to start (3.8 and 5.4). So I feel that I accepted a possibly unnecessarily elaborate system, more elaborate than I probably really need, for twice the price. And didn’t receive the drainage mat that I was told would be part of it."

"We recently had our entire brick building tuckpointed in Brookline and the results were outstanding. The crew was professional, clean, and extremely detail-oriented from start to finish. They matched the mortar perfectly and made the whole building look brand new again. They showed up on time every day, kept the site organized, and finished the project exactly when promised. If you need full building tuckpointing done right, I highly recommend this company. Top quality workmanship and very fair pricing."

Basement Waterproofing questions, answered by experts

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.
