Improving Crawl Space Storage in Mill Creek, WA

William wanted to turn their crawl space into extra storage and improve access. The crawlspace was quite tall at around and did not appear to have many water issues according to him. We found signs moisture during our inspection and designed a solution. We installed our CleanSpace vapor barrier, SmartSump, and Foamax insulation panels to help create the safe, dry storage that he desired.

Mill Creek, WA, Crawlspace Sump Pump System

After living in her home for several years, Sandy of Mill Creek, WA, decided enough was enough. Her sump pump was running constantly and driving her nuts. She believed the underlying cause might have been a creek under home causing it to continuously run. After her free inspection, we devised a plan to get rid of her water and sump problems for good. We upgraded her bucket sump with a TripleSafe sump pump system. The water gets pumped from the low spot of the crawlspace out and away from the home through a freshly installed discharge line. We lined the entire crawlspace with a 20mil thick CleanSpace encapsulation system.

TripleSafe Sump Pump Installed in Mill Creek Crawl Space

Sandy D. had been living in her Mill Creek home for 13 years, all the while battling a humid and musty crawl space. She had a sump pump, but it was very outdated and she complained about how it constantly ran and the sounds it would make drove her nuts. She had done some personal research online for solutions and ended up on our website. She was very intrigued by the look and functions of our sump pumps, as they were much different than the bucket she was previously using.

Sandy decided to have her pump replaced by Rainy Day with their TripleSafe Sump Pump. This incredible pump is three pumps in one, allowing the owner to rest with ease by knowing that if one pump fails or cannot handle the volume, another is there to help; and a third, battery operated pump is there to run in case of a power outage, this is all done automatically without any obligation from the owner. The pump is also equipped with the WaterWatch Alarm system, a product that will alert Sandy if it comes in contact with water so they can handle the matter right away before it could cause serious damage.

Rainy Day is pleased to have replaced Sandy’s sump pump and contributing to the healthiness of her crawl space and ultimately her home.
