"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."

"While I am pleased with the quality of the job, I didn't like the owner trying to add more than I agreed on. I got a call in the am from owner Anthony Stanko telling me he had a canceĺlation. He asked if they could do my driveway that afternoon. I okayed it. He responded, but left once his crew started working. He returned when the 3" layer of asphalt we agreed on, was in place. It was then he tried to sell me an additional layer, saying it would prevent water damage. He offered it for an additional $ 2500 initially, but when I hesitated he dropped the price first to $2000, then $1500, without any negotiating by me. I became suspicious his "am" cancellation called for more asphalt than was needed to do my driveway and felt he was trying to recoup his losses by dumping it on me."

"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

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.

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.

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

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

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.
