I will recommend AA Action to anyone in need to basement waterproofing, crawl space improvements and related items."

"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!"

"We have been working with Affordable for a couple of years now. To put it lightly, we have the basement from hell. When they arrived, we had some water in the basement and they quoted us based on their normal pricing. Once the concrete came up, we couldn't believe what we were dealing with. It is a constant flow of water that required two sump pits and an insane amount of work to install our drainage system. Every time they tried to dig a pit it would backfill with sand and water- they had to dig this up painstakingly- foot by foot. We thought for sure we were in for additional costs, but they stuck by the original estimate. Since then, any time we have had an issue or a question, they are quick to answer. Poor Kelly and Bobby probably recognize our number on the caller ID but whenever we make a call or send an email, we always get a response- usually with a visit on the same day. We highly recommend this company for their honesty, customer service, and quality work."

"We had a basement waterproofing issue. Shopped around a couple of companies. With the best rating on google, and with good reason, Best Buy Waterproofing was our choice. Rob was knowledgeable, diligent, patient and open towards our questions and concerns. Best experience I had with any company rep to date. He came out twice to our place (once the first time to look at the issue, second before he took the work to make sure we all are on the same page.) And then he was there before the work was started to make sure all of us were on the same page. The crew that came out (Darwin, Juan, Raul, Hammie, Chilo) were very careful about their work, respectful, and meticulous. They plastic sealed the work area to prevent dirt, and broom cleaned the area after they were done. Even after the work was done and the transaction was completed, Rob came out to check the work and to make sure it was up to his standard. He olso brought with him the mold treatment up on my request and took care of that as well. Thank you Rob! I highly recommended Best Buy."

"Wendell truly lives up to his Companies name. He can be trusted to get the job done right. I needed help quickly as our house was on the market and the record rainfall was taking a toll on our basement. Wendell had his team come in within the next few days after the initial consultation and waterproofed the basement walls. They did need to come back and secure a few leaks, but he took care of it immediately. I'm very pleased with the work they've done and would refer them to my family and friends. He also offers a 3 year warranty, which gives me peace of mind for any future needs."

"Juan and his team did another great job for us. They performed this necessary repair in a timely fashion and were very professional. They had to coordinate their work with the basement waterproofing people and they have no problem doing that. We intend on using this company for several other repairs in the future, and I would strongly recommend them!"

"Yes. Jay was great! He came and did an inspection and suggested I wait for the heavy rain that was coming to see if I had any issues. I called him back about 2 weeks later and he returned to drill into 2 areas in my basement. Put a camera or scope in to see if there was water in the walls? none! He cleaned up and caulked the holes. And would not take any money. He said only call him back if there were more problems"

Basement Waterproofing FAQs, answered by experts

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.
