The folks I talked to are very nice and patient. I contacted them to give me a quote to level the concrete slab in Mid October. Dave visited my house in early Nov, he was very kind and spent an hour on the site to help me figure out the scope of project and give me many useful tips, and they later followed me up with more suggestions and a more detailed cost estimation.

I can't believe I get to be the first to review these guys! I had a chance to work with Ephraim. All I really needed was a few bags of gypsum concrete floor underlayment (aka Gypcrete) to repair some flooring in my condo due to flood. I did not expect to meet the god of gypsum concrete floor underlayment himself. Talking to Ephraim makes you wish for future floods just so you can go by some more gypsum cement from him. He took the time to carefully explain why he recommended a product, how to install it, and answer all my technical questions about it. Really great experience overall.

Jeff and Co are truly professionals, as good as you can get. I have contacts with many contractors and Jeff attitude and approach is at the top. He and his crew have leveled my two level concrete floor. When crew came to do the work, after pouring material, it turned out not to be "workable". It was getting hard too fast. Jeff worked with material supplier on issue and did not charge me for performed work.

So crew had to come second time to complete job. Crew meticulously protected street, pavers and entrance outside of house with nylon sheathing, and they spend time afterwards to make sure everything is in mint condition. I would say they spent on work itself an hour and additional 2 hours to make sure everything was properly cleaned. They did all "small" things without me telling them what to do. They simple took care of business.
