Your company did an excellent job in our commercial building. The work was accomplished in a very short amount of time and the result was a perfectly leveled floor. The polyurethane system you use is very impressive!

"Dusty was excellent. He was efficient, considerate, and worked very hard to install the push piers. He is an outstanding employee. His crew also was excellent - courteous, efficient, and most helpful."
Mr. P.

"Amazing Amazing Amazing. I hired Yellowstone Structural to reinforce my deck pillars and to add a Sump pump in my basement. I was out of town when the work was done. When I returned there was no sign they were ever there. Except for the installed pump in the basement. Despite needing to move landscaping, plants and grass in the areas around my deck, everything looked untouched. Everything was cleaned up perfectly. They took detailed pictures of the work so I clearly could see what they did. I was amazed by the level of care they took. The great customer service started with the initial estimate and continued beyond final payment. This really is a great company with obviously fantastic leadership. I highly recommend this company."

    To stop moisture from passing through your floors and porous concrete walls, a crawl space vapor barrier should be installed. A durable liner will allow for servicemen to use the space without damage while transforming your crawl space into usable storage space. This is also the best time to install crawl space insulation on your walls or floors. Installing crawl space drainage matting underneath the crawl space liner will help direct water to the drainage system and sump pump.
