Work Requests From Longmeadow, MA
Briarcliff Rd in Longmeadow
During the recent rains, we had quite a bit of Water/mud coming up thru the basement floor where water main enters the house. We have a sump - the pump is new, but water level did not rise in basin, as far as we could tell. Also taking in lots of water in the corner where foundation wall meets the chimney in the basement.
Shady Knoll Drive in Longmeadow
I found water in my basement Saturday morning. I had a fan blowing on the area all day Saturday. When I checked it Sunday morning it was almost all dry. When I checked it again Sunday afternoon it was wet again. I have tried to get answers from two other service companies and no one has gotten back to me.

Problem with an exterior retaining wall.
Pendleton Lane in Longmeadow
Stamp-crete walk adjacent to concrete steps to house dropped by 1-1/2" to 2". Section which dropped is part of sidewalk which is already sawcut, so it is not cracking. It is approximately 10' wide by 4' long. Appears to be a good application for slab jacking. I can send photos which are self evident. Access is unhindered.

Lincoln Park in Longmeadow
Since moving the driveway from the east side of our home to the west side we've been getting constant water in on the east side of our basement. It appears the ground slope is attributing to the problem and apparently the old driveway's position did help the problem. Also have what appears to be a leaking gas vent on the roof as well that we need repairs. Would also like to see what sealing the floor/walls of the basement would cost.
