This Lebanon, CT crawlspace used to be damp and dirty. When it rained, water would collect here. After putting in the CleanSpace vapor barrier around the crawlspace, we installed a SmartSump sump pump and a Sanidry CX. The SmartSump and SaniDry CX are specially designed to fit in a crawlspace environment, and to keep the space dry for years to come!

This old dirt crawlspace used to have water problems. It was humid and wator vapor would seep into the house via the crawlspace. We installed the CleanSpace vapor barrier in the home. This durable, bright white crawlspace liner was installed on the walls and floors, preventing water vapor and humidity from passing through. By keeping this crawlspace dry, we protected the structure from mold and rot.

When we got here, this crawlspace was wet, moldy, and filled with debris. The old fiberglass had fallen because it absorbed water and got heavy. We installed the durable, bright white CleanSpace liner on the walls and floors, preventing water vapor and humidity from passing through. With its mold-resistant additive "UltraFresh", CleanSpace will never support mildew or mold growth on its surface. Now the owner of this Lebanon, CT home will have a clean, dry crawlspace for years to come!

Work Requests From Lebanon, CT
Project Location: Lebanon, CT
Built a new construction home, after a couple years of settling I have a couple of cracks in the foundation that occasionally get water coming through them during periods of sustained heavy rain. I'd like to get these filled. In addition to that, I also get water coming in where my Bilco door is (also only during sustained heavy rain). I would like to get a quote on what it would cost to fix these issues.
Project Location: Lebanon, CT
Slanted floor on second floor and doors that sometimes don't close on first floor. Home has high humidity and, based on what I read, it may have shifting soil under foundation (we have 5 sump pumps). The main focus is to ensure the structural integrity of the second floor, starting with the analysis on how the foundation or other systemic issues like humidity or water control are causing the slanted flooring on second floor.
Project Location: Lebanon, CT
I have a walkout basement door. When it rains heavily (such as 4/23/23), I have ponding outside the door which enters the basement. FYI, I have an existing drain & sump system for part of the basement, which you installed.

This is not for a basement, but we need your skills! We need to have a trench cut, the kind of trench you would cut for water drainage in a basement. We have a slab of concrete and need the trench to drain water away that pools after heavy rains. The slab is the foundation of a building that has been razed and there is no cover to the slab and exposed to rain. The original concrete flooring of course was not designed to be outside and exposed to rain. We would need two trenches, each about 20 feet, but looking to you to advise. We might just have the bare trench, or maybe you could suggest additional things. This is VERY urgent for us! It is keeping us from moving onto other aspects of renovation. Please get back to me soon.

We live in a split-level ranch, so our lower floor of the house is half underground. The floor and some of the walls are cement. In the summer is it very humid and mildewy down there. I run a dehumidifier all summer long. There is also very occassional small-scale flooding, but we don't know the source. I'd like advice on what steps we can take to make it a more temp/humidity-controlled space so that it is more usable throughout the year.
