Understand the Health of Your Cold Room

Cold rooms are often under porches, patios, or walkways. When water seeps into the ground, excess moisture can enter the cold room which encourages mold growth and threatens your home’s structural stability. We recommend contacting a waterproofing expert if you notice any of the following:

Water & Moisture Problem Signs

  • Efflorescence (a white, chalky substance on cold room walls and floors)
  • High humidity
  • Musty smells

Control Cold Room Wall Moisture

What We Do

Unwanted water in your cold room might cause mold, damage your belongings, and ruin fabric, wood, and other materials. This moisture doesn’t just enter your cold room through open doors and windows but gets through the smallest cracks in your walls, meaning you need a reliable vapor barrier to keep everything dry.

What We Do

Trying to keep all water out of your cold room might increase pressure on your home from the outside. Instead, you’ll want to control the amount of water accumulating in this area and stop it from damaging your property. Our interior drainage and sump pump systems redirect excess water from your cold room, resulting in a drier and healthier space.

Had some water infiltration couple of weeks ago after some serious rainfall. I knew my previous owner had used them before and i use them to service my sump pumps.

From the initial quote to the actual work – everything was professional. I am in the construction industry for over 20 years. I can tell you the installers of Dave and Ryan were fantastic. Care for the work.

We had this backup system in our last house. I would highly recommend as we had 6 years with no issues with water and minimal to no maintenance.
Fantastic business super easy to deal with and professional.

George brought his wealth of knowledge to the table and educated me on everything about a wet basement. I would recommend him to any one suffering through this predicament. He was able to calm us first time homebuyers and advised us on the best course if action.

Rob was able to come pretty quickly. We discussed what occurred and Rob was able to identify the probable cause of our flood. So we have a little bit of work to do and Rob will be staying in touch to ensure this solved the problem. Best news I’ve had all week!!!

Had them in to redo a horrible, installed wrong, ineffective waterproofing system. Thrilled with the workers and the install. They do have a wait period to get the install but you don’t want to hire a company that doesn’t these days! I wish we were able to have tried some of their more high tech solutions but our house is very old so it wasn’t possible. But know they have new very cool options that might work for you!
