Crawl Space Repair & Encapsulation Expert

Your home’s crawl space is often neglected. It’s usually too small to be seen as valuable and most people dread going into their crawl spaces because they are often damp and dark spaces that are so low they hurt your back. However, we feel like crawl spaces can be more valuable than that. We offer a variety of crawl space services that are guaranteed to turn your crawl space, regardless of the condition that it’s in, into an inviting and safe storage space. We can make any repairs that are needed and also encapsulate the space with a durable white plastic that brightens it up and creates a barrier from moisture.

Project Location: Fitzwilliam, NH
I have a small area (about 3 ft) where ground water enters. It seems to be the cold joint between the footing and the wall. The wall above the leak was repaired in the past.
Project Location: Fitzwilliam, NH
We recently moved into an older home in Fitzwilliam and realized we have a few leaks in the basement when it rains/snow melts. One is coming through the stone and there is another coming down from the side of the wall in the basement. We were wondering if this is something you might be able to help us with? We do have a sump pump currently but the water levels have been rising well above it and I'm not sure how old the pump is. Please let me know. Thank you!

Basement flooding hydrostatic pressure pushes water up through cracks in the floor. Small ranch.
Project Location: Fitzwilliam, NH
15x15 dirt floored basement area. Used to be only a bit damp, now taking on considerable water after melt off and rain. Old well there but water appears to be from runoff. Did some regrading in the fall but that doesn't seem to have done much. Field stone walls need hydraulic cement, sump pumps needed, perhaps drainage pipes. I'd love a temporary solution to make it better through the winter since I'm presently carrying buckets. Perhaps schedule full job in the early spring.
