Flooding basement
Vicinity of Gloucester Dr in Harrow
Basement has 2 leaks, 1 in crawl space and the 2nd beside our fireplace.
Vicinity of in Harrow
Hi there, I purchased a home last summer that has a crawl space. We noticed last year that after a heavy rain the crawl space would have water in it which would eventurally dissappear. In the fall I had Warkentins dig a sump pit in the lowest area of crawl space and hook up a sump pump. I also laid down a vapour barrier (did not tape seams). Recently we have noticed a distinct odour coming from crawl space (not sure if something to do with spring thaw?). I would like to have someone from your company look at crawl space and recommend any steps that should be taken to deal with issues? ie. should i have vapour barrier professionally installed? should seams be taped? should we waterproof edges of crawl space and have tiles tied directly into sump pit? Any other courses of action Thanks Shawn
