Needed a drainage solution in my backyard to avoid water in my crawl space. GF provided a variety of recommendations and price points and guided me to a solution that was best for me. Workers arrived on time, did a great job on the installation, and left the area in good order. Definitely recommend!

I hired Greenfrog to take care of a drainage issues around our foundation. Their communication and follow through were top notch from the very start. Their plan was logical and aesthetically pleasing. Their workers were respectful and careful. Greenfrog is not the cheapest company, but they doing very high quality work, use high quality materials, and hire high quality people. Highly recommend!

I had French drains installed in my back yard and down both sides of my property, to the street. Starting with Laura, who did a great job in reviewing the job and cost and sending updates, to Luis and his crew, who did the actual work so fantastically. They were professional, caring of my property, and considerate to me - in so many ways. Luis explained to me what they were doing each day. When they were finished, it did not look like they had dug trenches in my yard. They were amazing. And - the cost was very reasonable. Green Frog is a super company.

Hired Green Frog to do a mold cleanup and encapsulation of my crawlspace. I highly recommend them based on the combination of high quality of work, fair pricing, and very responsive customer service.I had reached out to and received proposals from at least six contractors. Including Green Frog, who had come recommended by a real estate agent friend who had seen their work. After a thorough evaluation of all the contractors, Green Frog stood out. For all of the reasons listed above.Blair, the owner, is both very knowledgeable and graciously accommodated my many questions. Even went so far to invite me to his home to inspect his crawlspace. Laura, my point of contact once the project started, was a pleasure to work with and very responsive -- email, text and phone. And their crew was quite professional. Particularly appreciated that they cleaned up the work site each day before they left.During the final walkthrough inspection, with both Blair and Laura, we found just one small item the crew had overlooked. Laura had them out first thing the following morning to take care of it. Can't ask for anything more than that.Doing an encapsulation is not a small ticket. I determined Green Frog's pricing to be very fair. Not the lowest, but those guys tend to be schlocks. But materially below the overpriced big names (e.g., MoistureLoc), with as good or better quality of materials and work.I highly recommend Green Frog.
