"Matt was up front about the cost and understood our policy to obtain estimates from 3 companies before proceeding with work in our home. He itemized the estimate and explained the procedure and warranty. He was pleasant to work with! He did not require an hour of my time or insist that both my husband and I be present in order to give us a sales pitch. The price was competitive and not inflated to cover marketing expenses. I like that the company is family owned & local, and that the workers are employees, not sub-contractors. The men who did the work were efficient and we have had no water in our basement since the waterproofing was done. I believe the contractors who followed Acculevel's work were a little surprised at the materials used, and they had to adjust their plans somewhat, but all is good in the end. Thank you!"

"Fast professional and friendly. Spot on when it came to the estimate all the way around. Job site was clean and looked better than it ever did before Buxton started the job. We would recommend Buxton waterproofing every time! Raymond Buxton is what I would call an honest hard working family man, he treats you like a family member! Kind of a Jack of all trades!!"

"My husband and I began notcing cracks in our basement walls within the last few months so we contacted Frank to diagnose the problem. He was very knowledgeable and promptly told us what needed to be fixed. His crew began work within a week of us meeting, they worked quickly and efficiently and the job was done in 4 days. They knocked out 30 feet of our basement wall that had been damaged and the work was done in an extremely clean manner. They left the area meticulously clean. We also had 38 feet of wall on the other side of our house piered because it was settling. Frank lifted the house and piered the wall with a jacking system. We were extremely surprised as to how quickly all of the work was done and appreciated the professional manner in which it was completed. Frank even provided us a lifetime tansferable warranty. We highly recommend using Frank for any foundation repair work.

Basement Waterproofing FAQs, answered by experts

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.
