Wet crawl space, 36 x 29 feet, about 1044 square feet. 4 ft. standing height. 2 inches standing water. No sump pump or perimeter drain. I would like a suggestion and estimate of repairing or encapsulating this space to keep it dry. May also be some exterior drainage issues from small sloping hill toward house.

Insulation install under the house and how a rats getting into that crawl space? We have insulation under the house but our concern has been that it was installed upside down.
Vicinity of Norman St in Sequim
We have noticed rodents in our crawlspace area,they have also been able to access parts of our home. The insulation below has been pulled down in much of the crawlspace. I am inquiring about how much it would be to replace the insulation, haul away the old stuff, and seal any places that rodents could enter the home/crawlspace.
