Job Stories From Hillsboro, OR
Proper Crawl Space Systems Restore Health and Value to You and Your Home

During times in the northwest when it just doesn't seem to stop raining (which is somewhere between 8 and 9 months of the year), do you every worry that your crawl space or basement is improperly waterproofed and water is seeping into your home? A little water won't hurt, but a lot can be detrimental to you, your family and your home's overall health.

Chris A. from Hillsboro, Oregon was experiencing some leakage in the crawl space and is concerned about the long term affects it might have. As this trend continues, you get standing water in the crawl space, which can lead to high levels of humidity and temperature. This will not only rot away at the wooden beams under your home, but can also lead to mold development which become airborne and breathed in by you and your family. 

Chris did the right thing and didn't hesitate to call us for help. By installing an effective drainage system leading to a sump pump for removal and a new 10ml vapor barrier, Chris can now be worry free that he is keeping the family healthy and restoring the value and health to the home.

Hello, I have two slabs of sidewalk on both sides of my property that needs to be leveled and pose a tripping hazard.

We have a dirt crawl space that is as deep as 6' and shallow as 3' in certain spots and we are interested to know if it's possible to dig it out for more space or if the cost outweighs the benefit. Would love for someone to talk me through the general costs or possibly come out for a paid consult to see our options. Thanks!

Concrete Driveway undermining. Will lead to problems in the future and would like to fill with expandable foam now.
Vicinity of NW Warren St in Hillsboro
My home is a little over two years old and the bottom right portion of the driveway has developed a crack. I didn't want to just patch it without figuring out what caused it as I am looking to get the driveway sealed. Looking to make sure there isn't a deeper problem and then if you are able to repair the crack. Please email me first but if you do call, do so after noon. Thank you.

I have/had a musty smell coming up through the floor into my living room and there still seems to be something lingering that is impacting air quality in the room. I would like to get the crawlspace checked out to see if there's a problem down there with moisture and/or mold or mildew.

We live in the downtown Hillsboro area. We have water entering the basement from an unidentified source. The basement is partially finished, which is complicating our hunt for the source of this water. We would like a bid on 1) seeking the source and 2) once the source is identified, a further bid on repair. Thanks!

Jeffrey Bryant front patio leveling.
Vicinity of SW Imperial St in Hillsboro
Our front porch slab has sunk 2-3 inches next to the front door. There may be other concrete in need of stabilization. I would like to know if it is worth trying to improve the earthquake readiness of the foundation and single-story ranch house on it.

I would like receive information on basement encapsulation and foundation crack repair.
Vicinity of NE Jackson Street in Hillsboro
We bought the house in Nov. 2017. The previous owners said there wasn't a problem with water in the basement. We had minor problems in Jan 2018 that seemed to go away with diverting downspouts. But this year, with heavy rain, we have had water seep up through the concrete and create a pool in the middle of the floor. There isn't a drain and there's nowhere for the water to go. We want to look at waterproofing options as well as sump pump.
Vicinity of SE Pine St in Hillsboro
