"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

DIY is possible for basic setups. Professional installation ensures proper drainage and reliability.

Not all window wells have a formal drain, but they all require a method for water to flow away from the window. Some wells are connected to an interior or exterior drain tile, which is the most effective solution. Others rely on a deep layer of gravel or crushed stone that allows water to filter down into the soil.

However, if a window well lacks a proper drainage system, it can lead to basement seepage, costly water damage, mold growth, and potential foundation damage. This is especially true in areas with heavy rainfall or expansive soil.

If your window well doesn't have a drain or is not draining quickly enough, you have a few options. For gravel-based systems, the stone may have compacted and needs to be improved. For a more robust solution, you can hire a plumber or window installer to connect the well to a drainage system. This can also be a DIY project using a shovel or auger.

A sump pump is one of the most common ways to get excess moisture out of your home, but it’s not the only way. If your home doesn't have a sump pump, other options to get excess water out of the basement include trash pumps, submersible pumps, service pumps, and hand-crank pumps. However, it’s worth calling a pro in to assess your situation and potentially install a sump pump for you.

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.

There are a few possible sump pump drainage locations, including a neighborhood storm drain, into a creek or pond, or underground. Don’t let your sump pump water go into your sewer or septic system. Ideally, your drainage spot should be on a downhill slope that’s at least 10 to 20 feet away from your home’s foundation. Before choosing a location, check your local codes and regulations.
