"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!"

"The team arrived on time to do extensive work on my basement floor and walls and outside underground drainage issues. They worked tirelessly all day to remove old concrete, lay a new pipe system, pour new concrete, install sump pump, and seals. They prepped the walls and sealed and painted with Loxon paint. Radon seals were included in the redone areas. The outside work included installation of a new underground drainage pipe with pop up exit drain. A rubber membrane was installed behind the house siding. We?ve had several days of heavy rain since the waterproofing work was completed and the basement floor and walls have remained dry. We recommend Basement Gurus to other homeowners experiencing waterproofing problems for dependable and satisfying solutions."

Basement Waterproofing questions, answered by experts

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.
