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.

    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.

Project Location: Berkeley Drive, Hudson, NH 03051

Comment: My dehumidifyer does not adequately function to keep my basement dry to protect items stored in the finished basement of my condo. It is currently draining into the furnace drain, but when the furnace is off the dehumidifyer tank fills up and automatically turns off--and requires monitoring to be effective. I have been trying to tackle mold growth in one corner of my basement near a small downstairs "closet" which is bare concrete and has pump for "radon" removal etc. and a sealed floor water holder tank related to the underground radon pipe installations.

Project Location: Tanager Way, Londonderry, NH 03053

Comment: When we get a sigificant amount of rain or melting snow, our basement gets water in two areas. The first spot is right under the door to the outside and the second area is a little more concerning to me; less water but underground and leaks up through the floor. Nothing that has ever required a pump but we would like to finish our basement some day.

Project Location: South Shore Drive, Pelham, NH 03076
