3 Pros Basement Systems did an excellent job from their sales personnel to the installers. The installers were very courteous and considerate. The installation took four days and they worked very hard. They listen to everything I had concerns about and corrected any issues that I may have had. In addition, they cleaned up after themselves and put everything back in place. I couldn’t have asked for a better team

"I just wanted to provide feedback that Brent was the service person that came to correct the issues he found. He is extremely professional and a great representative for your company. He deserves a raise. It is quite unusual to find someone that is so committed to the company they work for and puts customers first. He is a great person to invest in as a company."

"Brent  did a fantastic job! What a professional....He called the day prior to verify the wall had been demoed and was ready for the repair the leak coming thru my foundation. He sent a text message that morning with an ETA and arrived as expected. Prior to starting the work he ran thru the details and asked if I had any questions. Throughout the process he showed the work that had been completed and continued to ask if I had any questions. Great experience and will call them again if I have another leak in my basement."

  "This company did an outstanding job under our house which was soggy and very badly mildewed. The odor penetrated our entire house. They cleaned it up and placed a strong secure lining with a waffled flooring underneath. Later we found out after quite a bit of rain the lining turned into a waterbed under the house lol. But they came out and installed several sump pumps and we've been great ever since. No one minds when they have to go under the house to work. I highly recommend this company for work around your house."
Victoria Z.
Clifton, VA
"I am so relieved that my new basement system is installed and running to provide a cleaner air environment in my basement. Brent was very patient and professional, taking time to explain everything about my new system and answering my questions without frustration. I really appreciate when a service tech takes time to explain the way things work to the consumer so I know what to do and when to call in the future."

    Sump Pump service visit in Winchester VA

    Having a sump pump can save you from potential basement flooding.  When a sump pump is working, it handles more than just water.  It also pumps in the loose dirt and sediment that comes along with that unwanted basement water.  Annual service is the key to keeping your sump pump clean and working the way it is supposed to.  Here you have a great example of a sump pump that has been doing its job.  Taking it apart and cleaning out the corrosion, dirt, and nastiness that is collected while it pumps out water is part of our service and maintenance coverage.  We service clients who had their units installed by us and clients with old units that need service.

    Winchester VA Sump Pump Service

    This Winchester VA home had a sump pump installed as part of a basement waterproofing project we performed last year.  The homeowner called to ask about an annual service check after some recent rains had caused the sump pump to run for a long period of time.  Our Service Tech Brent went out to visit and checked the whole system.  The sump pump had been exposed to lots of water and had sediment building up inside.  Brent took the unit apart and gave it a full cleaning before putting it back in place.  We service all sump pumps, even if we did not install them.

    This Boyce, VA homeonwer was looking for a healthier, cleaner home with less mildew odors.  The 3 Pros team found the biggest issue was the damp crawl space beneath the home.  The crawl space was encapsulated using dimple matting, TerraBlock insulation, CleanSpace vapor barrier, and a beautiful Smart Sump Pump.

    Boyce VA Crawl Space Transformation

    This home in Boyce VA had a large crawl space that had been treated with old school, traditional methods to address water and moisture issues.  The old methods of installing a layer of plastic covering the floor and some insulation on the walls did not work.  The homeowner was experiencing a musty smell in the crawl space which was noticeable in the living area of the home above.  Our Sales Pro Stephen inspected the home and identified a solution.  Installing Terra Block matting on the dirt floor, covered by a layer of Clean Space was what did the trick.  Silver Glo insulation panels were used for the walls of the crawl space.  This helped to control the moisture and water in the crawl space and improved the air quality in the home above.

    Berryville VA Wet Basement Floor Solution

    This unfinished basement in Berryville VA had wet floors throughout most of the space including an attached crawl space.  The existing sump pump wasn't placed correctly so water was building up all around the dirt floors making mud and wet spots.  The water was coming in through the walls and under the foundation whenever it rained and the basement was too humid and smelled musty.  Our production crew laid down Terra Block and drainage matting to cover and seal in the dirt floors, allowing air to flow beneath and the water to keep from collecting anywhere in the basement.  Clean Space was used to cover it all and to wrap the foundation piers and lower parts of the wall.  This created a proper moisture barrier and kept the musty smell from being able to develop further.

    Protecting a Home with a Reliable Sump Pump System

    Homeowners in Markham, VA had water intrusion in their basement on multiple occasions and were ready to fix the problem. After receiving a free evaluation, they decided to take the steps needed to ensure their basement stays dry all the time. The 3 Pros Basement Systems team installed CleanSpace on the walls, WaterGuard around the perimeter of the basement, and our TripleSafe Sump Pump. WaterGuard is an interior basement drainage system in which water enters via inlet holes and flows through the drainage pipe to the sump pump. Most sump pumps fail because of either a failed pump, a pump that can't handle high volumes of water or power failure. The TripleSafe assures protection from all three sump pump problems.
