"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!

"Really well! I had them replace all the supply lines to our toilets because 2 out of 3 original lines had leaked/were leaking. They replaced all of them with sturdy, updated lines. The next day one of the toilets needed adjusting because the float valve wasn't set quite right. They came back and cheerfully adjusted it, at no charge. I will definitely use them again."

Basement Waterproofing FAQs, answered by experts

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

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.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts
