Hi, we have a crack in the foundation in our basement that leaks in one area with snow melt on that side of the house in the winter months. Definitely not a rush or an emergency, but whenever you have time to come take a look, I would love to get an estimate for the crack repair. Thanks!

We recently purchased a house about 2 years ago. We have a sump pump but have still occasionally ended up with water in the basement. We would To have someone look at it and give us a quote to prevent water from getting into it in the future

Water pooling up in basement during heavy rain.

I will be re-flooring the basement office soon and have noticed that I had moisture under my computer matt. I want to make sure that there is not moisture between the concrete and the laminate that I put down to prevent mold from growing.

High humidity and "musky" in basement due to water seepage thru concrete near floor. I would like an estimate (following in house inspection) for a sealing job. Thanks.

We are purchasing this property and there is an issue causing water in the basement. We would like to get an estimate on fixing the problem.
Project Location: Merrimack, NH
I sometimes get water on the floor in my basement when it rains. I don't want water to come into my basement when it rains.
Project Location: Merrimack, NH
Just bought first home, found out there had been previous termite damage (termites have been dealt with but damage done.) Main support beam was chewed up and probably rotted causing the floors in the house to shift really badly. We would like to redo the floors but cannot until they are leveled out. There is definitely mold and a lot of moisture in there as well which is putting a lot of strain on the furnace as well as getting mold spores into our HVAC system. I would like to see how much the cost of repairs might be so we can get these issues resolved sooner than later. Thank you for reading my concerns.
