"From the first visit to my home from Sean for an estimate, to the crew that arrived to do the project I was impressed. Everyone was extremely professional. The crew arrived on time, the crew leader introduced me to the rest of the crew and explained how they would proceed with the project. They protected the work spaces with plastic from my garage to the crawl space opening in side my closet. They went to work and kept me informed about the progress. The whole crew worked very efficiently and got the project done in one day. They left work area spotless when they were done. I would highly recommend this company for any waterproofing project!!"

"They came up with a list of things needed to be completed. I have decided not to have anything completed at the moment. He was professional and prompt for our appointment. Everything went very well. I would probably consider using them in the future. There was a leak in the toilet in the master bedroom. He ended up actually making it worse. My husband was able to fix this problem himself."

"They did an inspection of the attic, and basement.  Determined the possibility of mice in the attic.  Set traps and returned a week later. Offered a year long extermination package that included patching access holes etc... set more traps and 2 other employees removed mice the following week.  We we probably most disappointed in the lack of professionalism.  We provided the ladder so they could gain access into the attic.  On the follow-up visit employee didn't use a ladder and simply pulled himself into the attic. The mice seem to be gone.  We haven't purchased the program.  Very pleasant communication with the office in arranging the appointment.  It was offered as a $99 coupon which was a reasonable price.  We considered the package but decided to wait to see if we still had an issue.

"Larry and Glen did work for us - this was the third job. They installed a 40' block retaining wall to extend our back yard. Then they installed a patio and two walks. Once again they did a great job for a fair price. These guys are the greatest."

Basement Waterproofing questions, answered by experts

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option. 

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.
