"It went very well.  He never varied from his estimate of labor costs and there was only a few extra supplies that needed purchasing after his original materials estimate but that was usually for extra work we asked him to do as the project progressed.  There were a few times when we observed things that we preferred another way (such as the color of paint used on the vents) and when they were brought up with him he adjusted very quickly.  Much of the work was done while we were on vacation and we trusted Ceaser with the keys to our house.  We're very happy with the final result.

"Doug and his son were super professional, but friendly. They did an excellent job of installing my new water heater and went over and above in explaining how to take care of it, etc. I will for sure be calling them if any other plumbing issue in the future. I am THE PICKIEST person on the planet and I HIGHLY recommend Doug and his son!"

Basement Waterproofing FAQs, answered by experts

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. 

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.
