"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!"

"Guys were professional and knew their stuff. Arrived on time,too. Solved my issue in 15 minutes. 'Was completely unprepared for the over $500 bill! My regular electrician was too busy but this was a fire hazard which demanded immediate attention. Wouldn't book with Baker's company again just because of outrageous price."

"Eastern Maine Drainage was quick to assess our problem and Nate was able to set up an appointment within a few days to remedy our drainage issue. He was on time, communicated clearly, and was tidy with his work. Since I was at work while he was installing the new sump pump and drain line, he kept me in the loop about his progress. He had a detailed estimate that he stuck to, and he even deducted the cost of some PVC when he realized he didn't need as much as he initially planned. I would recommend him to anyone needing work in their basement."

"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!"

Basement Waterproofing FAQs, answered by experts

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.
