I had 3 other basement companies come out to give me quotes on stopping water from coming into my basement and fixing one of my bowing walls. Bill from Greentree was the only one to look outside my home during the inspection after taking a look inside to see if there were any issues they could take care of outside as well. He was also the only one to notice my egress window did not have a drain installed. The quote was $2000-$4000 cheaper than other companies and more work was to be completed by Greentree (drain for egress, sealing egress window from outside, re-sealing all other basement windows, sealing a noticeable crack in foundation on outside, installed 2 I-beams on bowing wall and installing the waterproofing system around the whole basement). The other companies were just going to install the waterproofing system and put up I-beams. Bill seemed the most knowledgeable and caring about the situation, not just wanting to sell the waterproofing system like the other companies. The crew that did the work was sure to contain the dust in just the basement. They were also sure to inform me of what they would be doing each day so I could decide if my infant daughter needed to be somewhere else for the day. They covered everything with plastic (including furnace/AC/water heater) and moved a few things to ensure dust wouldn't get all over everything. The foreman (Kevin?) explained the sump pump and back up before they left at the end of the week and made sure to answer any questions I had. For anyone having water troubles in their basement and not wanting to spend the fairly large amount of money to fix it, just do it and you'll be glad you did. Once you see all the work involved, you will understand the price better. And once you have flash flood rains and have NO water in your basement for the first time, you will be wishing you had fixed the problem sooner. I no longer have to run my dehumidifier 24/7 and already seeing the savings on my electric bill as well.
