"John the owner was very professional. He explained all aspects of the waterproofing work that was to be done. Any questions we had, he answered so that we understood what was to be done. He was respectful and pleasant during the entire process. When we left messages needing to speak to John, he was prompt in returning our calls or texts. John's crew was also professional and resp0ectful. They were thorough in performing the waterproofing job as John had explained it. The work was completed within the timeframe. The crew did a great job on the waterproofing as well as cleaning up the areas. We are very pleased with the completed. There has been an extremely heavy rain for an extended period of time since the work was completed. I can honestly say the water problem is no longer an issue--basement is totally dry. We believe we made the best choice in choosing John's company, Brother's Waterproofing, LLC, to do the work,"

"Basement Waterproofing Nationwide did excellent work in a timely and proffessional manner for a reasonable and appropriate fee. They said they would complete the work in 1-2 days and were done in one day. They were very careful and left things neater than they were before they came. We have used them before with great success and would use them again. So far, the problem we had, water in our basement, has not recurred, and our basement is bone dry. Tnank you Basement Waterproofing Nationwide."

"We are the 2nd owners of a 15 year old home. Don't know why the original owner/builder did not put a sump pump in the basement, as it would have been a cheaper option in the end. If you are building a new home with a basement, put a sump pump in, don't scrimp on what is a very valuable insurance policy. After looking at a handful of other companies to retrofit a sump pump in our cellar, we picked All Aspects Waterproofing, LLC. They did a great job! Very high quality work, and outstanding service. They did a great job! We enthusiastically recommend All Aspects Waterproofing to any homeowner!"

"I contacted AquaGuard when I noticed signs of water in my basement. John Riley contacted me the next day and did an inspection of the area. He explained the issue and solution and within 3 days workers were on site fixing the problem. John kept in touch throughout the process. The work to dig a trench and water proof the basement was completed in 2.5 days. Iâ m very satisfied with the work and would recommend AquaGuard Waterproofing, ask for John Riley."

Basement Waterproofing questions, answered by experts

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

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.
