"We are first time home buyers and Greg was recommended by my real estate agent. It was immediately evident he knew what he was talking about and has a wealth of knowledge and experience. He went above and beyond answering our questions after the actual inspection about different aspects and getting his advice. We got a binder full of resources as well. When we got a first heavy rain of the season and some water appeared in our garage, he came back immediately and hopped on our roof to see what was going on and diagnosed the issue. He even brought my fiance up on to the roof with him to show him some tips on maintenance. He is a true gem of a professional--I will be holding on to his card as he will be our trusted go-to if we ever need his services again or have a friend to pass his information on to."

"Immediate call back when requested quote, and great service. Crew workers are hard working and respectful. The work performed went way beyond the basics... from cutting down 3 ft weeds, removing debris, spraying for weed control, trimming under bushes, cleaning up edges of flower bed, and then spreading bark. I would hire them again, and recommend this company ?."
