"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."

"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.

"Eric did what he said he would do on the schedule he said he would. He is very professional. They did a good cleanup after their work. Both the Condo Association manager and my contractor felt he did a good job. In fact, a neighbor has already hired Granite Piping to do the same fuel tank replacement in their unit based upon the manager's recommendation. I recommend Granite Piping highly. Don"

"I contacted Jackson and Company to obtain
a quote; Mr. Jackson contacted me within a few hours! Rick was polite and very
professional during our conversations. He came out to see the cracks to ensure
that my quote was accurate, especially since I had explained that someone had
attempted to "repair" the cracks previously. Rick arrived promptly at
my home and reviewed my situation. He answered all of my questions and
addressed all of my concerns. He also explained that his work would be covered
under a transferrable warrantee! I had several other quotes however no other company
offered any type of warrantee.
Rob arrived on time to do the job. Rob
was so nice and professional; I was greeted with a smile and a handshake. I
really wanted to see the process and he took the time to explain each step to
me. He worked tirelessly to clean up the mess of the failed ?repair? I could
not believe how much better it looked! He then proceeded to perform the repair allowing
me to watch and take pictures, it?s quite the process. He left both areas that he
worked on immaculate!
I have such peace of mind now knowing
that I will no longer have to worry about there being a huge puddle in my
garage or basement or water spouting out of the cracks! I am so glad that I
chose Jackson and Company to perform this work for me and I would recommend them
to anyone!

Basement Waterproofing questions, answered by experts

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.
