Job Stories From Happy Valley, OR
Liu Happy Valley, OR Crawl Space Encapsulation

    Happy Valley, OR is located in the hills on the eastern border or Portland with a collection of beautiful homes overlooking the west side of the city. Happy Valley is also the location of multiple "Street of Dreams" events. The "Street of Dreams" is a home builders dream in which million dollar homes are built to inspire creativity and wow the imagination with a focus of home efficiency. So it is no wonder that Happy Valley home owner Henry Liu was interested in encapsulating his crawl space. Henry searched the internet for a qualified installer and called TerraFirma for a free estimate. 

    By encapsulation your crawl space you achieve many things. One of which is energy efficiency and healthy air conditioning. The goal of encapsulating your crawl space is to condition and control ALL the air under your home. By controlling groundwater seepage, isolating the earth from the home and blocking off the vents, Henry is able to control 100% of the air in his crawl space. Crawl space air accounts for 50% of the air on the first story of your home, and 50% of that for each additional floor. With healthier, mold free air, we have achieved one of Henry's main goals. By insulating the crawl space, air stays warmer under the home. This means less energy is used to heat the house making it not only more comfortable but cost effective to maintain. 

    A simple three day project gives home owners, like Henry, healthier, more comfortable and cheaper living. The project pays for itself after a few years.

Hi, I am the real estate agent representing the buyer for the above property. Will it be possible to have someone inspect the house this week, as our inspection contingency is up on Friday? thank you!
Project Location: Happy Valley, OR
I would like to schedule a time to meet with a Terra Firma representative to review two conditions at m y home. 1. A sagging beam that needs to be shored up with a new post and footing to eliminate a sag in our front porch. 2. Raising a sinking portion of our front walkway which also serves as a footing for the front porch stairs. I'm hoping that foam jacking will work for this condition. Can you call me to schedule a time to review these conditions and provide a quote? Thank you.

Very similar to the sample on your website with the Portland area high crawl space. Original vapor barrier not put down very well, some standing water, had previous water intrusion into crawl and puddling has never abated. Home is 22 years old and the issue needs to be looked at and addressed.

Patio has dropped about 2 inches and the concrete is cracking around posts that support our deck. Would like to have someone look at it and get their opinion on what can be done and the cost.

I have a daylight basement with a musty smell. We thought it was due to a leaky window in the basement, but that was fixed and the musty smell persist. Today, I looked in the crawlspace and there appears to be water coming in from where the driveway and garage meet. I was hoping someone could come out to determine if that is the source of the problem or not and provide a quote to remedy the problem.

The template made me select a "Main area of concern" but concrete leveling isn't an option so i selected Crawl Space. I actually need to get a quote for concrete leveling at the entryway of my home.
