"I received a phone call from Forest Excavation within 1 hour of my request. They were very professional. The complaint I have is that home advisor contacted a professional no where close to the town I live in. I think if you are going to recommend professionals home advisor needs to correct how their location searches and apply what the person has entered for the demographic info."

"So I live in a older house (1947) so the plumbing is older too. Anytime I used my sink dishwasher or laundry the water would all but flood my basement making it almost unusable. I called and talked to Seth he was able to get to my home the next day and diagnose the problem my pipes in the concrete were old and clogged beyond repair well he managed to completely redo all of my plumbing brand new and have it up and running in a matter of a few hours! I now have a dry usable basement. He gave me a very decent price as well! Now hopefully I don't need another plumber anytime soon but if I do I'm calling seth at SWB!"

"I have an old farm house. It is at Least 200 years old. It has a stone foundation. Every spring my cellar fills with water. I was given a quote in November on 2022. They installed the water proofing that December. They kept to quoted price with no surprises The crew kept to the schedule I was given. They were professional and left my cellar looking better than I have ever seen it With the soft winter and dry spring I was afraid that their work would not get a good test. However, last night We got four to five inches of rain. In the past this would at least left a foot of water in my cellar. Today it is bone dry. Basement Improvement is a local family run business that I would highly recommend to anyone."

"I called Octagon the day after we had an upstairs water leak. The next day, Octagan had scheduled a technician to assess the damage and set up the mitigation solutions to dry out the damage before mold could set in. Everyone from Octagon was friendly, professional and very responsive. If you need a fast, reliable and effective response, you will find it with Octagon!"

"Though Rob was extremely courteous and prompt, he quickly diagnosed that we would need to drill into the basement floor to create a sump basin to prevent further flooding, at a total cost of about $4500.00. Wanting a second opinion, I called my plumber. Within seconds of walking into our basement, he found that we already HAD a sump basin, and that an old house trap was clogged and causing backup to the basin. For $1000.00, the plumber removed the house trap and ran the line directly to the sewer, cleaned the sump basin, and we have not had an issue since. In the end, we saved thousands of dollars and a lot of unnecessary drilling which would not have fixed the issue. I do not think that Rob was being deceitful in any way, but I was disturbed that he did not find the existing basin which was under a large, loose tile in the utility room where we stood discussing the issue for 30 minutes. In my desperation to fix the problem, I very nearly did not get a second opinion; boy, am I glad I did!

Basement Waterproofing FAQs, answered by experts

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

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.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.
