"Northern basements was able to fit us in quickly, pulled our crooked cement wall back in-place and sealed the wall to prevent future leaks.  The work was timely, communication was friendly and detailed, and price was as to be expected for the large amount of work that needed to be done.  We are very pleased with the whole process as well as the results.

"The work itself, the actual basement waterproofing appears to be working but our flood season hasn't come yet so, I'm reserving judgement. But, the way the work was done was a problem and the initial way that they got with the problem wasn't satisfactory. Eventually, months after work I did get some resolution but is wasn't a smooth transaction. We moved some of the finished portions of the basement to do their work and the way that that was handled was very sloppy and rushed, and very expensive to repair. And then, when the initial point of having somebody come and look at all my questions, it was not the owner, it was his foreman and it was not dealt within a professional manner. After 2 contacts, tried to explain what the problems were and has offered that they have an annual service to make sure that everything is working and there's a fee for that, though he offered 2 years of that with no cost, so that was a nice gesture. He tried to make up for the problems but like I said, there were problems."

"I hired Twin State Basement Services to install perimeter drains in my basement after experiencing a water problem caused by hydraulic pressure under the floor. From the time I placed the phone call to the completion of the job it was clear to me that I was in excellent hands. I promptly received a call back within 24 hrs of it being placed. In all phases of the job from the size up and quote to the the completion of the job their work was beyond reproach. Refik and his crew were timely, efficient, courteous and professional. What impressed me the most was Refik's attention to detail and his personal commitment to "doing the job right". Nobody likes to have a water problem in their home but doing business with Twin State Basement Services made it much more palatable. This company was a great find for me. Highly recommend."

"Kyle was on time, honest and an extremely hard worker. He cleaned and sanded down our foundation then used cement to seal the footing and the foundation and also went the extra mile to go to home depot and get something for a huge crack he pointed out in the foundation from top to bottom. He fixed that and then sealed it. Gave the estimate same day he was out. Excellent work. Would highly recommend"

"We contacted Richard regarding the job, and had a quote back within the week - good quote.  He quickly responded to any questions  we had, and scheduled the work.  They completed the demo in one day, a few days before the cabinets showed up - if I had to do this again, I would hold off on the demolition until the cabinets were in, as it is difficult to live without a kitchen, especially with children.  It took approximately two weeks for the kitchen to be completed, with slight delays due to a damaged cabinet, time for the new countertops to set, appliance delivery, etc.  One hitch developed when the dishwasher was hooked up incorrectly, and water ran into my basement - I called Richard, and once I got through the answering service, he contacted the plumber, and we resolved the problem immediately over the phone, and the plumber was at my house at 8 the next morning ( a Saturday of a holiday weekend) to permanently fix the problem.  At the end of the two weeks, we had a great new kitchen, well installed, and we were thrilled!"

Basement Waterproofing questions, answered by experts

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.
