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.

    Customer Testimonial

              Hi to Tim Wicks and the 2 nice men who worked on our basement;Well, it's been 6 weeks of a dry basement and everything is back in its normal place.  The pump does come on maybe once a day now, but early on it was every several minutes, then after 2 weeks, every couple of hours, dwindling down to what we have now...maybe once a day. Our cats enjoy having that basement space back and we enjoy the "peace of mind" of a never-again wet basement! Thank you all for the work, advise & help.  Best wishes for the future, Judi & Tim Root

    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.

    Customer Review

    By Nancy H.
    Bomoseen, VT

    This was a very good company to work with. I worked directly with Matt Clark and he was very responsive and accommodating. The only service I had was encapsulation of a basement that has a dirt floor and "knee walls" in a seasonal residence. I needed to reduce a very bad humidity problem that developed. The crew did a very good job of leveling the dirt and removing large stones prior to installing the mat and liner. I highly recommend the mat, as it provides an additional layer of protection to support the liner.It has been one week since the installation. Unfortunately, while the musty smell is gone, the humidity problem is still an issue because the surface of the liner is wet from condensation (no pipes are leaking). I believe the purpose of the liner is to reduce, not completely eliminate, the temperature difference that leads to the humidity. So I will use a dehumidifier for awhile and see if that eliminates the condensation problem. If it does, it will leave me wondering whether I spent a lot of money to encapsulate the basement when all I needed was to run a dehumidifier! The basement walls have some foam insulation that runs the perimeter at the top of the walls, but it may turn out that I need to add more insulation. Time will tell - one step at a time!

    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.
