"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!"

"Highly recommend! Guardian Foundation LLC is a professional company, with a professional workforce. The work crews are knowledgeable, courteous, and answer any questions completely. The job was completed exactly the way it was bid. There were no hidden fees, add-ons or extras that were not in the bid. The company came sooner than expected. Their workspace was cleaned each night. Our project included a trench drain in the basement with a sump pump and dehumidifier, installation of 8 steel beams and jacks, and burying a gutter system to divert the flow of water away from our house. Overall, the work crew was good natured, pleasant, and just really enjoyed making our hosue more stable."

"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 questions, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

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.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly
