These two photos show the before and after of the chimney piering job Matt Clark's Northern Basements did.  The homeowner was concerned about the chimney falling away from the house and worried that the chimney could collapse.  They contacted Matt Clark's Northern Basement Systems to find a solution because of the companys excellent reputation with such situations.  Northern Basement Systems were able to not only stabilize it using our patented piers, but also lift the chimney to it's original position.

Crawl Space Repair & Encapsulation Expert

Your home’s crawl space is often neglected. It’s usually too small to be seen as valuable and most people dread going into their crawl spaces because they are often damp and dark spaces that are so low they hurt your back. However, we feel like crawl spaces can be more valuable than that. We offer a variety of crawl space services that are guaranteed to turn your crawl space, regardless of the condition that it’s in, into an inviting and safe storage space. We can make any repairs that are needed and also encapsulate the space with a durable white plastic that brightens it up and creates a barrier from moisture.

Hi - Looking for help regarding sagging floors and a crawl space. The sagging floors seem to be in multiple rooms throughout the house and I believe it could be due to (or at least accelerated by) a lot of the heavy rain this summer. I believe the crawl space was built in 1977. The house was my grandparents' from 1982-2016, when I bought the home from my grandmother. A lot of the house is still "original" (some strong 70's vibes in some rooms), so I imagine this might be somewhat expected wear and tear, with the added help of the heavy rains. Thank you & hope to hear from you soon, Jessica

Wet basement. Water appears to be coming up through the floor.

I have water leaking in the basement/ garage of a house that I bought 5 years ago. It never leaked previously. I had the septic pumped, but it is still leaking especially when it rains. There is a drainage ditch outside that may need an update, and a crack outside in the foundation opposite of where the leak is, that looks like it had a previous "patch" done once. I am happy to send photos.

Can you fix the small leaks/cracks in my basement garage wall from the outside if necessary? I think previous owner tried to seal two small cracks and put tar on the outside wall. This week, I noticed small rain puddles making their way along my basement garage exterior wall in two spots. I'd appreciate you coming out and giving me an estimate. Thanks.

Modular home, replace vinyl skirting with insulated wall structure. Prevent mice etc from getting in. Also inspect and repair fiberglass bat in floor joists under home. 1990 modular home, 24 x 44 home is on a thick, flat. concrete pad supported by 26" cement block piers. I want to reduce air infiltration to the crawl space, increase thermal efficiency to keep house warmer in the very cold snaps ( 0 degree F) we often have during the winter. Any suggestions are appreciated. --Art
