"Mount Valley is the epitomy of an honest, fair, reliable, efficient, professional, and customer service oriented company. Our coordinator, Ryan McAlister, was extremely knowledgeable and informative during inspection of our crawl space water issues, and his subsequent repair recommendations. Ryan was like a professor explaining retrofitting encapsulation of the crawl space and basement water issues with a slab, along with discussing such encapsulation during a new build vs. standard floor insulation in a crawl space in a climate above 60% humidity. Fascinating and educational discussion for me as an homeowner with very limited knowledge of the subject. Ryan was patient and is truly an expert. He also provided additional advice on other ground water issues and recommendations for us as homeowners to try, outside the crawl space, in order to save us money. His crew was extraordinarily hard working and diligent, personable and friendly. They did a great job in every detail relative to trench digging, gravel, wrapping, wall insulation, sump pump, dehumidifier, and drainage. Very well done and much appreciated professionalism and expertise. Very impressed with the coordinated team work demonstrated by the whole crew, Damian (foreman), Mac, and David. Very impressive young men. My wife wanted to adopt them and Ryan upon completion of the project, which was done in grueling heat, humidity, and wet conditions. Job well done. Great company.

"He tried to see if the water heater could be repaired, but it was too damaged from rust. He replaced it with a new one with a six year warranty. He protected the floor with plastic from possible leaks before he removed it and was careful to clean everything up before he left. He also made sure it was working before he left. He was very nice."

"They didn't end up doing the work. They were really high on what they wanted to do. Other people who looked at the porch said that it was not causing an issue with any water intrusion and that there doesn't seem to be any signs on the posts that this could have been recent, it could have been long ago. So no work was done. It was a front porch that had just the level concrete on one side was dipping just a little bit. I think they were going to pump it up from underneath or something like that to level it out. I would say that their response time and their professionalism of getting the quote to us on a timely manner was good. The quote was high and yet the work was not necessary according to other quotes. They should be honest to say when repairs are necessary and when they are not. The guy who showed up was nice and professional and was on time. There was a decent response time."

"Everyone we dealt with from Cantey Foundation Specialists were very professional, timely, and caring throughout the entire process from job estimate to the actual work done. While the work done did not bring all areas back completely to their original states, with the exception of one area, they were all pretty close. Realistically, It's very difficult to fix in two days what has taken place over a period of years. I am very satisfied with the job done. Grayson (job estimator) and Estevan (crew leader) were very helpful and great to work with through the entire process."

"Bought this in the spring to use before burning in the fall/winter.  Ended up moving in December and did not use it.
I'm wasn't sure how to score a company I didn't use (and not reviewing isn't really an option), so I just picked a score consistent with the average rating.

Basement Waterproofing questions, answered by experts

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.
