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.

              Steve Galvin installed my new pump and battery backup system. I couldn't be happier with his professionalism, timeliness and workmanship in this latest installation. The reason why I hired your company to come back. Perhaps in a few years we'll finish the basement as well. Thanks again guys! Great job.

    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: North Wilmot Road, Wilmot, NH 03287

Comment: My basement has water 11 months of the year and I'd like to get it dry. There is a large crack in the cement floor, and the cement block walls leak on 2-3 sides where they meet the floor. I have a sump pump now that is a DIY installation, but it works fine at keeping most of the water out [at least until the power goes out]. I'd like to know the method(s) you might have available to fix this issue, and how much it would cost.

Project Location: Highland Mountain Rd, Tilton, NH 03276

Comment: My basement gets very wet especially early spring with all the snow melting and the rain we usually get. It can be an inch or so of water. Is this something that would help?

Project Location: Francesca Way, Nottingham, NH 03290

Comment: Just wanted to know price

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'.

Project Location: Sunnyside Drive, Greenland, NH 03840

Comment: Looking to waterproof my basement to hopefully finish it in the years to come.

Project Location: Pease Rd, Meredith, NH 03253

Comment: There is a poorly installed and plummed sump pump already there. It is a 1900s cape. Beasment is extremely damp but no standing water currently.

Project Location: Perkins Road, Rye, NH 03870

Comment: Wet basement and sump pump issues

Project Location: Hare Rd, Milton, NH 03851

Comment: We need a new sump pump hole. We have water issues in the basement. The current sump hole is not adequate and I think it is in the wrong place. I know part of our problem is the water coming up from under when the water table is high (like right now) but parts of the base get very wet but near the sump hole it is still dry. Right now though it is really all wet.
