"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"Amed and Antonio did a wonderful job installing the pump system. What was going to be done was explained and I could observe if I wanted to. Steve who accessed the job was excellent. I was very happy with Dryzone and would gladly use them again if needed."

"I was very pleased with the job they did. They resolved the water problem I had I my basement. They were very professional. The owner spent quite a lot of time initially determining where the water was coming from and then with his crew resolved the problem. I highly recommend this company."

"I can't say enough about Watchman Waterproofing and the owner Dave. I got a few estimates for a drain because of water coming into my basement and decided to go with this company based on speaking with the owner Dave (Great Personality) and a fair price. He was very through walking me through each step of the process and didn't try to sell me something I didn't need. I needed to have the work done as soon as possible as I'm in the process of moving and with all the rain we've had and the rest of the week was not looking good with more rain to follow. He told me they were extremely busy and wouldn't be able to squeeze me in for a couple of weeks.The other company could start in a few days and their price matched Watchman by a hundred dollars. The next morning I get a call from Dave and he told me they had a cancellation and could start the work the immediatley I was thrilled! The crew showed up and they were very professional from start to finish. Great Company and fantastic owner!!! Thanks Dave :)"

"I've come across some very unprofessional contractors. I would say 90% of the contractors I have dealt during the remodeling of my home never called back or looked at my job and never returned an estimate as promised. The good news? ALL PRO Waterproofing isn't one of those companies. They were AMAZING. They sent someone to give me an estimate immediately - they called quickly to conform the install and they always showed up on time and ready to go. ** I would have given them 5 stars, but I found the price a little too high - but other than that - if you need basement waterproofing done right, don't waste your time with anyone else and call A"

"We recently had a radon system installed. Thomas was easy to work with, reliable and seemed deeply knowledgeable about radon and radon systems. The process went as described and the basement radon reading decreased in the first few days and has stayed reduced. We had the system installed over a month ago, but I wanted to be sure to give a review."

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
You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home.
However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
