"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"The whole process was very smooth. They came out and spent a couple of hours assessing the problems...turns out we had several. The water heater burner had failed and was under warranty. But they also discovered our pressure regulator had failed, our gate valve was frozen, and we had a pipe leaking in the wall! They found the necessary part for the warranty repair and drove 50 miles each way to get it rather than make us wait 1-2 days for for the part to be shipped. They stayed until all the problems were resolved which was greatly appreciated! (My wife and three daughters were not relishing cold showers!)"

"Raul did a great job for us. He took over a bathroom remodel job that had been started by another contractor. We know contractors don't like to do this, but Raul was willing to take on the challenge! He was excellent at communicating with us throughout the project, and kept to the budget. We would definitely recommend him!"

I purchased a big deal for this service and it worked out good. I just did not really jell with the designer so I did not use them. I did not like his ideas and did not like how they threw out the dollar amount for the project without knowing what I wanted to do. They are good, but it just did not work for me.

Basement Waterproofing FAQs, answered by experts

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. 

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
