"I strongly caution anyone considering doing business with this company. I gave them a deposit of $4,428.65, and when I canceled a week later they kept almost $900 of it even though my service was not for another 6 weeks. You do sign a very simple, clearly stated document that says, “Should you cancel beyond three business days, you understand your deposit is non-refundable. Northern Basements may choose to refund depending on cancellation circumstances.” I fully acknowledge that I canceled a few days outside that window, but I hoped an honest company that cares about customers and referrals would choose to provide a full refund. I am a sucker for hoping that. They chose to risk my impression, referral and review for $885.53. If nothing else comes out of this, I hope everyone reading at least goes in knowing that this statement on their contract is a real threat and your deposit is hostage. Even Airbnb’s offer full refunds on deposits within just a few days of people’s arrival date. 3 days to cancel with service not scheduled for 6 weeks out, “C’mon man.” No materials were used. No service workers’ time was taken. The manager justified the 20% withholding as credit card fees, restocking fees, time and resources for the estimate, and administrative fees. I wholly accepted responsibility for the credit card fees and time of Paul, the gentleman who performed the assessment, and I offered to settle at 10%. I still believe any reputable company would have provided a full refund at this point in a project, or at most deduct the credit card fees, because nothing more went into this beyond what would have normally been a free estimate. The further arguments the manager made for the additional fees were the scheduling of their team and allocation of materials for my project. Complete nonsense, especially when the project was not set for 6 weeks away. Because they had my deposit hostage, they had control of how much they decided they wanted to keep, it was completely arbitrary, and they kept almost $900 of my money without providing anything. If they wanted to cover their credit card transaction fees, fine, at most 6%, but the rest is absolute robbery. The only solace I can find in this loss of almost $900 now is that I didn’t spend another $13,000 with them. I tried to call Paul after speaking with the manager to ask if he could do me a favor and try to reason with the manager on my behalf because he seemed like a nice enough guy. No answer. No call back. I will never seek out this company’s services again and I will actively discourage others from doing so but, based on my experience, I expect they really don’t care."

"Basement Improvements waterproofed my basement and poured a new concrete floor. Both my basement steps were ruined by Basement Improvements, LLC. I have steps from my garage to the basement that they removed and destroyed. They also ruined the step from my house to the basement by cutting the steps instead of putting the concrete around the step. They cut the steps 2" high. They also buried the lines from my oil tank and heater in concrete. I filed a complaint with the BBB and expect to be reimbursed. The communication was incredibly poor throughout the entire process. I did not know my steps would be cut or that my lines from to the oil tank and heater would be buried in concrete. Nothing about the process was communicated to me until I asked a series of process questions. My questions about the process were treated as a burden. It was never communicated to me that my steps would be cut. It was never communicated to me that my connections would be buried under concrete. It is never communicated to me that my steps up to the garage would be damaged. I regret using Basement Improvements and wish I had chosen a more professional and responsible business. I regret not choosing TC Hafford. I choose Basement Improvements because the cost was lower, but with all the poor workmanship, my cost is higher. Don’t make the same mistake I made, choose a professional company to do this work."

Foundation Repair questions, answered by experts

Ensures structural stability and long-term safety of the building.

Mudjacking is usually reserved for light-duty slabs, like patios, driveways, and sidewalks. However, it can be an effective way to lift garage slabs and concrete around the perimeter of the home, which could harm your foundation if it’s not done properly. The risk of damage is why having a professional mudjacking company carry out the work is important. This type of slab or foundation repair is relatively inexpensive, especially if you consider that a DIY job requires that you pay to rent the necessary equipment.

Most of the time, normal foundation settling will present as thin cracks in the foundation and minor creaks in the floorboards. In contrast, you can identify foundation issues by wide or uneven foundation cracks, horizontal or step-shaped gaps on the foundation wall, or cracks that go around corners of your foundation. Foundation problems can also cause changes in your living area, like increased humidity, uneven or sloping floors, nail pops in drywall, countertops pulling away from the wall, and windows and doors getting stuck. When in doubt, call in a professional to identify the underlying cause.

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

Foundation problems are costly to repair, but if you already own the home, you can either handle the issues or allow the property to (literally) sink into disrepair. The opposite is true when buying a home. Walk away if the seller refuses to lower the asking price once foundation issues are exposed or if they refuse to handle the problems before the completion of the sale.
