"Northern basements was able to fit us in quickly, pulled our crooked cement wall back in-place and sealed the wall to prevent future leaks.  The work was timely, communication was friendly and detailed, and price was as to be expected for the large amount of work that needed to be done.  We are very pleased with the whole process as well as the results.

"Mitch was asked to do a small install in the bathroom. He gave an estimate with cost detail that turned out to be accurate. He was quick, efficient and neat, providing the exact install requested. I would hire him again in an instant."

"I called Rowells Services to have an in-house drain unclogged. I was able to get an appointment that afternoon which was great. I was told that I would get a call when the techs were on the way. That did not happen , but they arrived that afternoon as planned. They immediately assessed the situation and elected to run a camera on a snake through the drain pipe. To do this they had to remove the toilet. They found the clog and cleared it. Verified that the drain was open and then reinstalled the toilet. They did a very nice job of cleaning up after themselves and left within one hour after arriving. This is all the good news. The bad news is they did not check for leaks when they reinstalled the water line to the toilet. The next morning we had water dripping from the slow leak in our finished cellar. I found the source of the leak and tightened the connection myself."

Customers say: Quick response

"Mr. Dolloff was prompt in his response to our inquiry into landscaping projects we were considering. He gave us a free estimate on several projects. The cost seemed very fair and we had him complete a quarter of the entire project ~ grooming a hillside with severe erosion and creating a parking area for 2 cars. The hillside is beautiful. Exactly what we wanted and better than we expected. The parking area was not what I would call satisfactory. But in all honesty, they completed both jobs on time but unfortunately it was just the day before we got all that heavy rain the weekend of October 21st. We are planning for him to complete the other landscaping we need down and he offered to clean up the parking area as soon as the weather settles down."

Foundation Drain Installation FAQs, answered by experts

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

No, you can’t drain your sump pump into your home’s sewer system. In fact, it’s against the law in many places because dumping extra water into a municipal water system can disrupt or overwhelm the treatment process. And for similar reasons, you shouldn’t discharge a sump pump into your septic system, either.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.
