Your Home faces Water Damage

1. The years 2005 through 2009 have been some of the wettest on record for the state of New Hampshire and many residents are concerned that this trend will continue indefinitely.

2. When storms & flooding hit your area, your basement is most likely to be the prime target for water damage.

3. Your basement is likely the largest single space in your home. If you allow it to be wet, moldy, humid, smelly, and unhealthy, you're abandoning an entire floor of space in your home. Additionally, a home with water in basement is nearly impossible to sell, and the basement air - filled with odors, dust mite feces, humidity, and mold spores - will rise into the rest of the house, ruining the healthy environment of the home.

Waterproofing your basement, however, can be a very extensive job and finding a responsible and trustworthy contractor is even more challenging, but that's something Basement Systems wants to change. What's important to you becomes a priority to us.

    Matt T. of Bedford, NH

    Customer Testimonial

              I just had Jimmy, Jack, and Steve install some Waterguard, Trench Drain, and Water Guard port. They were very professional and fun to have here. They sealed off the work area as tight as a hospital isolation unit so that nothing in the basement had a speck of dust on it. In fact, after they done, the work area was cleaner than it had been prior to their arrival. It was all easy breezy and at a good price. I'd also like to thank Dan Doyon for coming to the house and explaining what would be done and leaving me with a professionally done proposal and autoCAD like depiction of the work to be done.

    I thought the work to install the system was outstanding. The only thing I think could be improved is the finish work. rough cement work and an old piece of wood to support the sump pump drain pipe.

    The installation crew found a potentially expensive problem that I was hidden behind insulation that I was unaware of. They repaired it at a fraction of what it might have cost had it gone unnoticed.

Comment: Have a house on a lake near Rumney NH with a basement that has residual mold and damp basement. Basement is about 900 sq ft. Am in process of drylocking the basement walls, adding foam panels, and have heard that your product might perform better than dehumidifier. In the spring, water levels are near the basement floor, looking at installing sump pump.

Project Location: Surrey Lane, Laconia, NH 03246

Comment: We have a sump pump system that works well. The outlet from the house is 1-1/2" PVC. From there it goes into the ground and into a smaller diameter flex hose. This is prone to freezing. We would like a Freeze Guard installed on the outlet and a LawnScape discharge at the other end. The underground pipe inbetween can be sized as you deem appropriate. The run underground is about 18'.
