"I was very impressed with George and the father/son team at MagCor. I asked for a quote on some exterior work and George was prompt and thorough in his response. He walked me through the sequence of the repairs and delivered on every aspect of the project. The quality of his work was outstanding. I appreciated his flexibility in scheduling, and his reliability. When the project was completed, George took the initiative to repair and touch up some other parts of the exterior of our home that needed attention. Why? Because he had extra material and paint and didn't want it to go waste. He made several trips to a local paint store to be sure the paint color matched, according to our HOA's standards. He went above and beyond what I even asked for or expected. A true professional!"

"After flushing the toilet, my sewer backed up into the shower. I called Thornton Plumbing from the Angie's List magazine. Kris arrived promptly. He unclogged the main line explaining to me exactly what he was doing and why he was accessing it from the roof. I had a similar problem 5 years previously, but the rotor rooter person who came was not that thorough or neat. Kris explained to me how the plumbing was probably installed under the house. Kris impressed me with his thoroughness so I asked him questions about my tankless water heater. Kris said it should be cleaned at least once or twice a year. It was installed two years ago and I had never had it cleaned so Kris said he could do it on this visit. Once again he did an excellent job, explaining to me what he was doing, and what I could do to make the job easier the next time. Two weeks later, my sink next to the toilet plugged up. I called Thornton Plumbing again and they said they would send Kris between 2-4 PM that day. However, Kris was detained on other jobs and never arrived. Brent called me about 4:30 PM and explained Kris was detained. Brent said he was at the office and he was willing to come out and fix the problem, but it would take him about an hour to arrive. I had taken the day off work so I could be at home when they arrived, so I asked Brent to come out. Brent did not arrive until 7 PM, two hours later. We were both tired by that time. The work they did was always very professional. I did feel that the second problem should probably have been solved on the first visit. Brent said he would not charge me for the extra service trip. I will call them again, but I will ask them to be sure and let me know if there is any chance they won't be able to make the scheduled time. I have to take off work to be home for repair people, and it was upsetting when Brent did not arrive until 7 PM."

"He was awesome.  He called back, but he was working in Reed field, North Carolina and he could not get to us for a couple of days.  By the time, he got to us we had already gotten the other estimates, and we were pleased with him.  Hampton guy was great.  He was really quick to get back to us, but he had other projects that he had already lined up.  The experience was very satisfactory.  He was very courteous, and prompt.  He was very honest in saying that he cannot get to us, and if we needed to have this work done now, then we need to have to get somebody else.  I appreciated that."

Basement Waterproofing FAQs, answered by experts

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

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.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.
