"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 FAQs, answered by experts

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.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.
