Your Home faces Water Damage

1. Connecticut has humid continental climate with seasonal extremes. With precipitation year round and heavy rainfall occurs during the summer thunderstorm season flooding is an issue.

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

3. If you allow it to be wet, moldy, humid, smelly, and unhealthy, you're abandoning an entire floor of space in your home. Additionally, 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.

Bruce Toth was the Service Technician that came to our house. He called twice to give the time of arrival which was appreciated and was right on time. Bruce demonstrated a strong understanding of the work to be done. He was personable and willing to re-educate me on the inner-workings of the pump and the ventilation system we have installed. He was meticulous, asked questions for input and answered all my questions. I was impressed and eager to write a review.

By Sven V.
Dobbs Ferry, NY

Your company Representative, Glen inspected my slab and immediately knew the solution, which he explained very well. The technicians who arrived on time to perform the work were very professional and performed an excellent job. They were attentive to protecting walls and other items in the house, totally impressed me in their abilities to perform this delicate work and even cleaned up after themselves, which I told them was not necessary at that late hour. Glen quoted the job and to the credit of your company there were no hidden costs the difference between the Quote and deposit was all I was required to pay, which was quite refreshing as you can imagine. I would recommend your company and have already done so to my neighbors who I believe have to have the same problem with their slab as I did. Thank you to your entire company including Ownership you run a tight ship.

Overall, my experience was excellent and although the price tag was much much higher than I expected to spend it was well worth the money. This is one case where I have to say you get what you pay for in terms of professionalism, organization, superior product and most important for us, your warranty. We are preparing our house for sale and the wet basement was a huge issue and now it is perfectly dry and completely a non-issue as we can point to your product and your warranty.
