"I contracted with Mount Valley Foundation to encapsulate my crawlspace. I worked with Trey to define the project work. He along Christian provided a competitive estimate and were available to answer my questions. The project included removal of all fiberglass insulation, fully encapsulating the space with top end vapor barriers, replacing the door, and installing a dehumidifier. The team worked for two days to complete all the work with the exception of wiring the dehumidifier which is being done by a third party. Cody led a team comprised of Cory, Zy, Billy and Lamont. They worked steadily and demonstrated they knew what they were doing. I was most impressed by their willingness to answer any questions. All of them were so polite. I would highly recommend Mountains Valley Foundation based in my experience. "

HydroHelp911 has been helping property owners repair their foundations and solve their moisture problems in North Carolina for many years. The company started out as Advanced Ventilation Solutions which grow quickly in crawl space repair and basement waterproofing, but we did very little in terms of ventilation services. This caused our company to re-evaluate the brand to reflect our core services and companies future direction, thus HydroHelp911 was born and ready to service the residents of beautiful North Carolina!

"Stay away! My project date was postponed 3 times and with each email notification I received, it stated this is a TENATIVE DATE. Frustrated, I canceled the contract only to discover that in the fine print of the contract language, HydroHelp911 gets to keep 35% of the total project cost. They chose to enforce the contract to the letter. My initial deposit was gone! All terms and conditions in their contract are written to defend HydroHelp911 legally. Again, they chose to enforce these terms even after 3 delays. Potential customers beware."

Sturdy Homes LLC specializes in structural repair and water mitigation. Bouncy floors, erosion around your footer, horizontal cracks on your basement walls, we can repair these issues for you. We have been fixing all issues associated with foundations for the past 10 years. I spent the first 4 years of that time being trained to properly fix these issues by a licensed engineer.

"Micah came to my home gave me a price and arrived to do the work when he said he would. He did an excellent job installing my French drain and waterproofing the house. The work was neat and clean when he was done. I highly recommend Sturdy Homes LLC for good work at a reasonable price."

Established in 1933, Olshan Foundation provides cost-effective foundation solutions to residential and commercial property owners. Services are backed by an available lifetime warranty, friendly customer support and convenient financing options. Free, no-obligation structural assessments are performed by Certified Structural Technicians. Since no two homes are alike, our Technicians carefully inspect the problems affecting your home before developing a comprehensive repair plan designed uniquely to your property. Olshan is the exclusive provider of the Cable Lock ST Plus repair system. This hybrid design combines the penetrating power of concrete with the long-term durability of steel, providing a longer, deeper more secure repair. We also offer drainage and root barriers to help prevent foundation damage. Schedule a free, no-obligation assessment now. Your home’s structural integrity depends on the strength of your foundation. It supports everything else – walls, windows, floors, doorways, roof – so when your foundation is damaged, it can cause serious problems throughout your home. Like most things in life, your foundation is subject to environmental stress. Expanding and contracting soil, excessive moisture and inadequate drainage are some of the most common threats to your home’s foundation. Over time, environmental stressors can cause a foundation to shift, crack or settle unevenly. And homeowners often miss early warning signs of foundation damage. Homeowners spend about $4 billion annually stabilizing faulty foundations, and those costs may increase as more homes are built in areas known for shifting soil. Understanding risk factors and signs of foundation problems can help you protect your most valuable asset from irreversible damage.

Basement Waterproofing questions, answered by experts

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option. 

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.
