"Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason. Waterproofing the basement and super sound and solid work! Doug was professional and very good at keeping me in the loop with the project over the 3 day visit, and created a solid system that we are confident will keep water out of the basement forever. Above and beyond as well with problem solving when having to find solutions to fit our basement layout, all with a solid financing option/great price and 5 year warranty/ yearly inspection plan. If you are stuck with water in your basement, get Groundworks working for you ASAP!"

"Morton Excavation was GREAT! I asked for 2 estimates, one with a small retaining wall, one without. After receiving the estimates, I contacted Morton and asked how soon could they get started? “Next week, and we should be done in a couple days.” They did have to put me off for one day, but they completed the job in 2 days, cleaned up the work area, and did an excellent job. Thanks!!"

"We had an area in our yard where we had removed a tree and grass would not grow. We tried reseeding for several years, and they result was always the same... a big bare patch. Dustin came up a great plan...stones, pavers and some plants, but plenty of room for us to personalize it. BTW...far right of the photo is a drainage ditch that he had to work around....integrated it nicely into his work."

"I have an old farm house. It is at Least 200 years old. It has a stone foundation. Every spring my cellar fills with water. I was given a quote in November on 2022. They installed the water proofing that December. They kept to quoted price with no surprises The crew kept to the schedule I was given. They were professional and left my cellar looking better than I have ever seen it With the soft winter and dry spring I was afraid that their work would not get a good test. However, last night We got four to five inches of rain. In the past this would at least left a foot of water in my cellar. Today it is bone dry. Basement Improvement is a local family run business that I would highly recommend to anyone."

"When I first called, I was surprised at how quickly they returned my phone call to set up an estimate. He was able to come over the next evening to check out our basement. He was punctual and provided us information about what would need to be done. He stated that he would provide us with an estimate that evening. I waited, but the estimate never came. I called the following week to see the status of the estimate. They stated that they were busy, but I should have it by now and would email it ASAP. After a second week, I called again. They said they would get it to me again. After the third week, I called again and was told the same thing. I gave up at that point and contacted someone else, who will be fixing the basement tomorrow. It's been over a month now and never received an estimate for the work. I understand that it's a busy time of year, but was disappointed to never get the estimate and didn't feel like I should have to pester them for it.

Basement Waterproofing FAQs, answered by experts

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.
