"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."

"Pedro and his team were excellent. They were professional and timely, hard-working and meticulous, and trustworthy. Best of all (at least for me), is that Pedro is VERY responsive and his team is assigned to get your job done and done correctly. They show up on time every day, and were willing to work late into the evening to hit the project milestones. Pedro was 100% clear about the costs, and he made sure I fully understood the areas where the costs were not known or where the costs could possibly change. For example, he said, "If you open up this wall, I'm not sure what we are going to find." I told him to proceed and his team opened up that wall and found that the previous contractor had installed literally zero insulation. Pedro met with me, reviewed what his team had found, went over all of our options, gave me his recommendation, and only proceeded when I completely approved the additional work that would be done and the additional cost entailed. Pedro is a true partner and his team does great work. I cannot recommend them enough. My wife and I have already booked them for another job renovating a first floor porch and creating a roof over the open-air second floor porch."

We are a full service residential construction and remodeling company. Our goal is to exceed all of our clients expectations through exceptional customer service and quality craftsmanship. We work with some of the best tradesmen in the industry to deliver a quality finished product. From deck and porch builds to siding and windows, we can do it all.

"I recently hired Coen Brothers Construction on a thorough bathroom renovation, and the outcome was outstanding. Their quality was excellent, and I am delighted with the final result. Their sub-contractors were also great and worked at the same high standards as the Coen Brothers. Although we faced some communication issues at the outset, we eventually worked through them, and it significantly improved throughout the project. They paid attention to detail; when my project manager saw me stripping the trim for reuse, they recommended buying new trim and a lumber yard to get it. And it makes a big difference having new trim with clean, sharp lines. Their tile work took longer than expected, but the miter cuts the trim cuts, and the finish is excellent. They were consistently punctual, respectful of my home, and very tidy - tidying up at the end of each day. While the project took longer than anticipated, the reasonable cost and the team's meticulous attention to detail compensated for it. Coen Brothers Construction also expertly handled all necessary permits and inspections, keeping me informed every step of the way. Overall, I am satisfied with their work and would hire them again for my next project."

Basement Leak Repair questions, answered by experts

While it’s possible to live in a damp basement, it’s usually not healthy to do so. Damp air affects your breathing, and it also promotes mold growth and pest infestation that can make living in a damp basement dangerous. You should plan to resolve any moisture issues and set up preventative measures before using your basement as a living space.

While both a channel drain and a French drain serve a similar purpose, a French drain is designed to prevent groundwater from causing flooding issues. This type of drain system goes underneath the soil and is completely surrounded by soil and rock. A channel drain, also called a trench drain, removes surface water before it ever enters the ground—hence the concrete and above-ground installation method.

Although waterproofing your basement may not directly increase the value of your home, it will protect the value you already have by preventing water damage. A basement without any signs of water will be more appealing to prospective home buyers. A leaky basement is a major red flag during a home inspection, and it will likely reduce the amount that buyers are willing to pay.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

The cost of installing landscape drainage with the help of a professional can vary widely depending on factors like the scope of the project, your location, and the specific services needed. Smaller tasks, such as installing a French drain, may range from $10 to $50 per linear foot, while more extensive projects like installing a catch basin can cost several thousand dollars to tens of thousands. Obtaining multiple quotes from qualified professionals is recommended to get a precise estimate for your specific drainage issue.
