Water entered crawl space and garage during rain storm

Project Location: Saint Helena, CA

Crawl space had water leak-now repaired-but there's a slight mildew smell in house. Need estimate for vapor barrier. House is 1,800 square feet.

Project Location: Saint Helena, CA

Hello, You did a great job on our rental house last year and want to do the same on our main house. Noticed that the soil is damp which is unusual, and i have had a plumber out with tools to cover off that their isnt any leaks from the plumbing. Could you guys figure out what is causing it as well as the vapor barrier? Thank you!

Project Location: Saint Helena, CA

We have moisture in the crawl space. The crawl space is quite tight and filled with the HVAC ducting.

The First sump under our sons room (installed by clean crawlspace) has been going strong for 5 years. We expect the New one under the kitchen area (which replaces the cheap quality "joke" we had installed by a private plumber, earlier) will last just as long or longer.. My advice is to hire only someone who does this work every day as their specialty, like clean crawlspace ! tom galligar

Quality Product / Quality Service - clean and efficient installation. Workers were courteous and took time to explain reason for length of time to do work, etc... Hardworkers - they deserve a raise! Have told a lot of peoples and friends (about your company)

I'm impressed by one of the owners coming back to fix a problem. He dug in and developed a solution and then got in and did most of the work himself.

Recently bought a new home it has many rot and mold issue as well as a standing water issue in the crawl space that will require a sump pump many areas throughout the home need attention for other issues thanks for your time

Project Location: Saint Helena, CA

Our home was built in 2000 and from the start our hard wood floors cupped. I'm planning on getting them redone but I'm told I should put down a moisture barrier first so I'm looking for a quote for that. The crawl space is about 2 1/2 to 3 feet with plenty of vents but always damp.

Project Location: Saint Helena, CA

We have one existing sump pump in our crawl space. We are remodeling our kitchen, and in that process our kitchen remodeling contractor thought we might need another sump pump or other crawl space work and recommended that we talk with you.
