"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."

"Barn Rescue – My barn was hit by a vehicle, which broke a large post and pushed section of siding out from under the roofline, plus major damage at ground level. Brad shored it up for the winter with an array of jacks and an enormous chain to ensure the thing wouldn’t fall down till they could return in the spring. Come spring, they fully replaced the damaged section’s support members and facade, and added bracing to the attic, rendering it stronger than before. Foundation support: The sagging beams and jerry-rigged support columns in the dirt basement of our 18th century house were inadequate. They dug and poured a dozen footings and lally columns, supporting a line of new 6x6 and 9x9 beams that provide solid support to the house above. They showed up promptly every day, worked fast, and left the site clean and finished. Both Brad and Chad have a deep knowledge about old houses and the techniques that were used, and I felt my historic register property was in good hands."

"We have had an intermittant water problem in our basement primarily when it rains heavily in the Winter.
I was very happy with the quick response from Mike Sears when we initially called to ask about repairing a water leak problem in our basement.  Mike explained how his proposed solution would work to alleviate the water problem. 
Mike left us with a detailed estimate and informational materials about the proposed repair.  He also explained what wasn't included in the job such as tearing out the current sheetrock, insulation and framing from the wall.  I did  this part of the work and the reconstruction after the drain had been installed.
We spoke to Mike a few days later, agreed to the price and set a date for the repair.
On the scheduled date, two of Mikes employees arrived on time and began to prep for the repair.  They did a good job of hanging plastic sheeting around their work area so that the dirt and dust would not get into the rest of the basement.
We had discovered a crack in the basement wall which wasn't visible when the original estimate was given.  Scott Lee gave  us a written estimate to repair it with carbon-fiber cloth and sealant.  While this was an unexpected expense, there was no reason to put in a drain and leave a crack in the wall.
Taking out a basement floor with a jackhammer and installing a drain is a hard, dirty job.  Scott and his co-worker completed this job in about 6 1/2 hours including the additional work for the wall crack.
They did a good job of cleaning up the old concrete and all working materials 
Scott explained how the pump would work when the water table under the house rose.  
My only issue with quality was the uneven concrete finish work on the basement floor above the drain.  Because this was leveled by hand, there is a somewhat noticeable depression in this area of the floor.
Overall, I am happy with the work and looking forward to a dry basement when the rains come this spring.

Foundation Repair FAQs, answered by experts

Most single-story homes don't have foundations strong enough to support a second story, but they can be reinforced for an addition. A structural engineer can assess your foundation and what needs to be done to get it ready. They'll look at any cracks or unevenness in your current foundation and consider any special framing or beams your home needs, especially if it’s in a high-wind or hurricane area.

“To support a second story, many structural engineers will require that you install additional concrete piers in the crawlspace,” says Tschudi. “This involves hand excavating, pouring a large concrete footing—usually with specially coated rebar—and then building concrete piers right up to the girders.”

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

Although some concrete cracks are cosmetic, others can be more serious. Cracks wider than ⅛ inch or that extend through the slab are serious and can cause structural damage. If you notice these types of cracks in your concrete patio, contact a local contractor who installs concrete patios to inspect the damage and determine how to fix it.

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.
