"I would like to express my most sincere gratitude to this company for the excellent work they performed in replacing the bathroom in my home. From the very first moment, they proved themselves to be highly responsible, punctual, and professional. The quality of their work exceeded my expectations; they paid attention to every detail, and the final result turned out beautifully. Their dedication and commitment to what they do are truly evident. Without a doubt, I recommend them 100%. It is difficult to find people who are this reliable and committed nowadays. Thank you so much for doing such an impeccable job. If you like, my dear, I can personalize this with the name of the company or the person who did the work for you, to make it even more special."

"First - hire Keith & I hope you read the rest. If you live in the Keys, you know contacting a plumber on the weekend is almost impossible. I had a water leak that was turning into a serious situation. He came over and stopped it quickly. Once he figured out what was causing it we agreed to have the shower plumbing repaired and the fixtures replaced. Then, because Home Depot would not install the new dishwasher because of old plumbing, Keith suggested he could do it. On the same day, he fixed the shower, repaired the sink plumbing, installed the dishwasher along with a new faucet & disposal. Keep in mind that this is an old house with old plumbing, appliances, etc. Keith was incredible. Incredibly competent and great to work with. If I were you - I'd choose him first. Thanks for everything Keith!"

"Work was done ok however, on follow up when I wanted lines drawn in parking area, no one responded to multiple calls. As a client, even IF they were not available to do this part of the job, I deserved a return call. Had there been a problem, I’m concerned that they would not have responded to that either. Poor communication is the reason for low ratings"

"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 questions, answered by experts

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.
