"First attempt at remediation was disappointing, but subsequently a more aggressive effort was made. I must say I was pleasantly surprised at the level of customer service and concern. In a time when warranties and customer satisfaction are just lip service, it is a refreshing experience to deal with a company that values its customerâ s concerns. I would recommend you consider Once And Done for your basement waterproofing needs.."

"Dave with 2 other workers were prompt and efficient. They came when they said they would and finished everything in 2 days. Everything looks fantastic because they protected my personal space with a plastic shield and cleaned everything up. Dirt and rubble was hauled away and they even sprayed my walkways outside. They installed the basement system and connected all my outside downspouts. I would highly recommend Highlander to anyone who needs waterproofing because they went above and beyond to make sure I was happy."

"This is the second time we have hired Groundworks (formerly Bakers Waterproofing) to perform work at our house. The first project was in 2017 when we had the waterproofing system installed. We called Groundworks a few weeks ago to get an estimate on lifting our front sidewalk and stairs that have sunk a lot over the past year. The steps had sunk to the point that the railings were not connected to the house, making it very unsafe for anyone coming into the front of our home. Aaron Lenker & Corbin Gillichbover were very professional and knowledgeable when they arrived to assess our sidewalk and steps to lift them. They left our sidewalk and the surrounding area better than when they arrived. Our steps and sidewalk are now level, and the railings are securely attached to the house again. We are thrilled! I would highly recommend Groundworks if you need a basement waterproofing system or any concrete lifted."

"The basement experts came in and patched up my wall around my well pump line that was leaking. I was getting water all along my front wall and two side walls when we got good rains. We’ve had several hard downpours the past few weeks since they did their work and haven’t gotten a single drop of water! Best price I found and great work. Can’t beat it thank you!"

Basement Waterproofing questions, answered by experts

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

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

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.
