"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.

"After interviewing many others we decided on A-1. They were far above average in knowledge, and knew how to get the job done with the least amount of disturbance to the surrounding areas. We would not hire anyone else for waterproofing. An extra plus was that they are Super nice people!"

Basement Waterproofing FAQs, answered by experts

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. 

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

While a standard gutter system is widely considered the most effective way to prevent water damage to your home's foundation, several alternatives are available. These options can be used on their own in certain climates or as supplementary protection.

Common alternatives include:

  • Rain Chains: These are decorative chains that hang from the roof's edge, guiding rainwater to the ground.

  • Drip Edges: These metal strips are installed at the edge of the roof to direct water away from the fascia. While often used with gutters, they can be paired with a ground-level solution but are typically not sufficient on their own.

  • Rain Dispersal Systems: These systems work by breaking up the heavy sheet of water flowing off the roof, dispersing it over a wider area.

  • French Drains: This ground-level system uses a perforated pipe in a gravel-filled trench to collect and redirect water runoff away from the house.

  • Drip Paths: Placed directly below the roofline, these paths made of concrete, stone, or other materials prevent soil erosion and guide water away.

It's important to note that some alternatives like rain chains and dispersal systems may not be adequate in regions with heavy rainfall because they don't divert water away from the foundation as effectively as a full gutter system. Ground-based solutions like French drains can be very effective but are often more expensive and can affect your landscaping and curb appeal. Many experts recommend installing a full gutter system for maximum protection and using alternatives as supplementary measures.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.
