"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."

"Mike was great. He took his time to explain what he was doing. I had a sediment filter installed and he replaced the pressure tank. He showed me how to check/replace filter as needed. He came by and diagnosed my problem without charging a service fee. He was very thorough and was not in a rush. His price was fair. He gave his professional opinion and did not try to "sell" me products that were not needed when I inquired about a water softener for my house. Great guys both him and his partner. I highly recommend giving them a call for your next plumbing job!"

"Gage is as professional as they come! He works efficiently, his rates are great and he left the site clean, clearing out any debris lying around. I am actually having him back today to do some other plumbing for me. When you find a professional that works above and beyond you keep them knowing that all your future jobs will be handled thoroughly and correctly. In my opinion Gage is 2nd to none. He is a keeper!"

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"Adam and his team did an amazing job on completing a backyard fence for my family. He was hardworking and detailed with the work. Kept me updated through every step of the way from the permit process, ordering materials and check-ins as the build was happening. Our fence is great! He also completed a custom railing and gate to attach to our existing deck. Will definitely be using we do it all again for future projects."

"Mike was able to fit me in the same day for an estimate which surprised me because I'm sure a lot of people are needing his services with all the rain lately but he was in the area that day and came by. Although the company is a nation wide chain, its a franchise and a small business. He is an honest Vermonter with Vermont values which I appreciate. He gave me options but didn't try to talk me into something I couldn't afford and is doing the work within two weeks which I was also happy about being a very busy time for this type of thing."

Foundation Drain Installation questions, answered by experts

A range of certified professionals can install French drains, from foundation specialists to plumbers. However, you’ll want to make sure that the professional has a breadth of experience installing the specific type of drain you need in or outside your home. Your contractor should also have experience with sump pumps, waterproofing, and flood-proof landscaping.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

The cost to install a new sump pump, including materials and professional labor, typically ranges from $1,000 to $3,000. The average cost is often cited between $1,200 and $2,500. Several factors influence the final price, including the type of pump, the complexity of the drainage system, and the installation location. For instance, installing a sump pump in a basement may cost around $1,200, while a more complex installation in a crawl space can cost an average of $3,900. It is important to hire a licensed professional for the installation to ensure quality work, which can impact the pump's lifespan and warranty. Note that these costs are for a new installation; replacing an existing unit is less expensive, typically costing $308 to $748.
