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: Hogg Hill Road, Bradford, NH 03221

Comment: Humidity and mildew

Project Location: Lois Dr, Hudson, NH 03051

Comment: It is down-pouring and water was leaking in through the windows in my unfinished basement. It happened for about 20 minutes but it is still raining just as hard but now it's not leaking's as if it just happens for the first little bit of the storm but it was a decent amount of water.

Project Location: Hillside Drive, Henniker, NH 03242

Project Location: Dearborn Road, Auburn, NH 03032

Comment: Need sump pump replaced, it appears to have been installed improperly by previous homeowner

Project Location: Haverhill Rd, Chester, NH 03036

Comment: Thinking of buying a home but there is water throughout the basement, not flooded but active water entering the house. It looks like there is a sump pump but I'm not sure how effective it is. The backyard seems wet throughout and there is even a small pond that formed from what looks like drainage from the houses roof. I'm not sure if it's a drainage problem outside, bad foundation, bad pumping or what. Just curious on an estimate. Thanks Brian
