"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.

"Rick responded immediately to my e-mail inquiry through the website and called me to set up an appointment.  He was extremely professional, courteous and knowledgeable.  As it turns out, after making the arrangements for the sump pump, we discovered the source of our water was from our heating system.  When we informed Rick of this and the fact the sump pump would not be needed, he promptly refunded our deposit.  I would definitely recommend Rick Jackson and will contact him in the future if the need arises.

Foundation Drain Installation FAQs, answered by experts

Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn’t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a flood wall around the house if you live in a flood-prone area.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

A sump pump will drain a flooded basement if it has a horsepower strong enough to remove the water faster than it is entering the room. If you have the wrong type or size of sump pump installed–or if your sump pump has failed–you may need to take additional steps to stop the flow of water or remove it manually.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Grinder pumps alone cost $300 on average. The average cost to install a new grinder pump is between $2,000 and $4,000, including the pump and labor. This price can also change based on the exact type of grinder pump you choose, labor costs in your area, and the power system your home currently has.
