"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."

I am a self employed General Contractor with subs who work under me, but also with me. I work on every job and I handle all my affairs. I always work under contract and with estimates. By the hour is exactly that, by the hour! I specialize in all phases of construction. I have been in construction for over 30 years and I am fully insured and registered with the State of NH. I am lead certified and I have a mold remediation company that does all my mold work. I do not charge for travel, as that is something you have to do to get to work. I work every job differently on the billing procedures, as not every job is the same. I work with customers on all phases such as design, paint schemes, window layout, lighting, doors, and general footprints for small additions and garages. I do all my own dirt work straight through to the finish work. And most importantly, when you call my phone, I answer it, day or night!

Foundation Repair questions, answered by experts

Yes, it is worth repairing concrete cracks. Concrete cracks are normal, and they can be hard to keep from appearing. However, it is worth repairing cracks in concrete for many reasons. For example, it’s possible to repair concrete to the point where the repair is almost invisible. Also, if the crack is left alone, it can become bigger and more expensive to fix over time.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

Home foundations are designed to last a lifetime when properly constructed and well-maintained. A poured concrete slab can last 200 years, while concrete blocks can last 80 to 100 years. A pier foundation can last about 75 years. Brick or stone walls can last 100 years or more.

Yes, you can fill cracks in concrete if you’re a somewhat handy homeowner. It’s important to know which concrete patching method to use, as small cracks require different approaches than large ones. It might seem challenging to determine which product to use and the tools necessary for the project, but with a bit of background, homeowners can restore their cracked concrete easily.
