"Quackers was the 2nd vendor to review the problem. The first vendor proposed a much more expensive solution. Quacker's saw that I did not have a sump pump in my sump pit so they proposed that this be the first step to fix the problem which so far is working. He also advised me to run new drainage tile away from foundation near where the water entered the basement."

"Our experience with Atlas Foundation Solutions, LLC was excellent. Their staff was very professional, prompt and courteous. Their technician, Jacob was very knowledgeable and thorough. He found another crack under the deck that was covered in the basement with insulation and shelving, saving us another problem down the road. Great job, thank you!"

"First the problem was identified. I thought I had only 1 crack, but I was only seeing the "relief" crack. The big crack in the foundation was hidden behind wood paneling. The work was done to fix the cracks & provide proper foundation drainage. Because the main crack was around part of the basement window casing, at my request, they replaced the window. Also @ my request, they replaced my sump pump (which was about 20 years old). The work was very professional. They were prompt, thorough, very neat; the work was done in about 2 & 1/2 days.  Everything was explained to me. The added work was my idea, not something even brought up or "pushed" by the company. When the problem was identified, all possible solutions were discussed. I was very pleased with the work done. It has been a year and a half since the work was completed, and my basement is dry, the cracks remain sealed, and I have a very nice looking new basement window.

"Really great experience with Perma Jack all the way through for an external sump pump installation. Rich came out originally to assess and plan and was much more thorough than other bids. Price was reasonable too compared to others. After scheduling, Marcus and Sam came out on time and got started working and finished well ahead of what I was expecting. They were quick and thorough and left the place looking better than it looked before. Sump pump is well positioned and inconspicuous and I am very pleased with how it looks and performs. 10/10 experience"

"I saw them in the neighborhood, so I got their details and they gave me an estimate. They were re-repairing a crack from 20 years ago. They did their work and cleaned up afterward. I waited until after 3 or 4 serious rain storms before this comment. The basement still dry. No seepage through the cracks. I should have called them a long time ago."

"It went perfect. Gary and his crew are our go to contractors for everything. They have done work on our house and landscape many times. I would trust them with everything. My kitchen pipe under the sink rusted out on New Years Eve one time. I called Gary and he was at our house and went to Home Depot just before it closed, for the parts and fixed it that night. Best Contractor ever. Very helpful and knowledgeable."

Customers say: True professional

"Marlon Tuckpointing did a professional and seamless job on my chimney. I had missing mortar, discoloration, and a cracked and worn down chimney crown. Marlon came out right away and performed an assessment, made everything clear (including the price), and stayed in contact with me during the entire process. What impresses me most is their accuracy in workmanship, including the type/color match of mortar as well as the waterproofing work that protects my home from damage. When homes are 60+ years old, it is time to start thinking about the mortar and brick that holds your home together. While durable, over time, sacrificial mortar degrades and it's time to call in a professional to maintain the look and stability of your biggest asset. I am confident that you can trust Marlon Tuckpointing to do the job and am happy to recommend them."

"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!"

Basement Waterproofing questions, answered by experts

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

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.
