David did a great job explaining everything, and Pedro and Ricardo were able to answer my questions when they were working on site. We had support jacks put in to stop the house shifting, and to support a floor where the beam wasn't built correctly. They poured concrete footers a few days before, so I know the support is good. Now the floor is much more solid. They ran flexible ducting to replace some old torn/leaking duct work. And they installed a new crawlspace door since our existing one wouldn't open without a prybar. I had to do some work under the house right after they finished everything, so I personally inspected all the work and everything was professionally done and just as advertised.
