"Chris and his crew went above and beyond the contact we had with. While he was here we had him preform an additional contract which was also completed in a timely manner. I would certainly recommend him for the landscaping that he did for us. We have additional work that we want done in the spring and Chris will get the first call."

"We hired Tyler and his crew from Quantum Contracting LLC to build a 10 x 12 pool deck and they did an awesome job. Hardworking, pleasant and professional. They cleaned up the area every night when they left and when the project was completed. Very skilled in their detail and carpentry work. We are so pleased with the end result and look forward to using it this summer. We would hire them again for any project and we highly recommend them. Paula and Stephen Russell"

Basement Waterproofing FAQs, answered by experts

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.

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