"Paul Swann evaluated our foundation problem and referred us to an engineer who provided a detailed repair plan. Unfortunately, the nature and scope of the proposed repair plan was outside the parameters of what Northern Basement System's themselves could provide. We appreciated their honesty and have been looking for a contractor to take on the project."

"When I first called, I was surprised at how quickly they returned my phone call to set up an estimate. He was able to come over the next evening to check out our basement. He was punctual and provided us information about what would need to be done. He stated that he would provide us with an estimate that evening. I waited, but the estimate never came. I called the following week to see the status of the estimate. They stated that they were busy, but I should have it by now and would email it ASAP. After a second week, I called again. They said they would get it to me again. After the third week, I called again and was told the same thing. I gave up at that point and contacted someone else, who will be fixing the basement tomorrow. It's been over a month now and never received an estimate for the work. I understand that it's a busy time of year, but was disappointed to never get the estimate and didn't feel like I should have to pester them for it.

"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."

"A half hour after I hit the online contact button, Brian Locke called. He was here in an hour to look at the problem and two days later he brought in a dump truck load of stone to fix the water problem in my basement. I no longer have a problem with pockets of water and slippery mud. Excellent service!!!!!"

"NE Renovations is a general contractor whose network of contractors provided services to me as I was getting ready to sell the house.  The electrical service went very well with Mr. Martucci doing great work and advising me about things that did not need to be done.  I feel that he was a great advisor!
The flooring in the basement also went very well with the NE folks advising me about the best way to approach the installation.  Everything was perfect when they left.  I truly appreciated their workmanship.

Basement Waterproofing questions, answered by experts

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.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.
