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.

My basement had a serious flooding problem and Green Frog's diagnosis was the only one that made perfect sense and was reasonably priced. This job involved cutting into the foundation, creating a drain system, installing a sump pump and discharging a long distance off of the property. It's been 9 months since the job's completion and the system is holding up well, performing as promised and has saved my home (and its value). Recommended.

Amazing. Just amazing. We had some serious stuff going on under our house & had called multiple crawlspace water "experts"... All the others (if they showed up) couldn't provide an assessment, much less a solution. We called Green Frog. They replied in a timely fashion. Gave us a fair assessment & quote. Arrived in time. NEVER left a mess. Adhered to our crazy yard wishes. Informed us of everything each day so there were no surprises. We have had many repairs done to our house and have NEVER had a company do what they say in a timely way for the price they said it was going to be like these guys. The little things that you think a contractor will do because it's just common sense, others ignore, but these guys do! One of the challenges was they encountered in the middle of the job that a previous contractor (Bainbridge - yuck!) had put a yard drain to help rainwater move from the gutters away from the house. Previous contractor had installed a drain box and a drain that just stopped at the box - there was no connection and it was covered with rocks so we'd never know. These guys halted work and pointed it out and fixed it without missing a beat. Hardest, honest, ethical workers we've ever worked with. Laura is an awesome project manager & her team were polite and attentive and truly engaged in the project. We are blown away by Green Frog!

Installed a french drain to address a flooding issue in our backyard. The team was very polite and professional and, most importantly, solved our problem. Highly recommend.

My driveway was flooding badly whenever it stormed, and I found four companies to bid on a drainage solution. Green Frog was one of the last two companies scheduled to quote, and Andrew showed up with his iPad. He listened to me, inspected my driveway, then carefully inspected the crawlspace of my house, my backyard drainage angles, and photographs I provided of an aerial view. He was there an hour at least, and I was beginning to think he was a bit obsessive about the quote. But he came in and sat with me, showed me diagrams of his proposal, a detailed quote, and a thorough knowledge of the issues. It was amazing. No other contractor had done anything like it, giving me quick oral estimates that in some instances seemed bizarre. I chose Green Frog, and their technicians showed up (on schedule in two weeks time) , worked incredibly long hours, and did a really spectacular job on the installation. It was all fantastic. I can't say enough about the old-school attitude of honest work and integrity that Green Frog embodies.

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.

We had issues with water entering our garage for years before we called Green Frog. Blair and his team were incredible to work with, and I'm excited to say we made it through the 2018 tropical storms/hurricanes (Florence and Michael) with no water in the garage!! Great, great work and I couldn't be more satisfied. Would highly, highly recommend this group to anyone.

Green Frog was a great choice for fixing our drainage issues tied extending our downspouts to the street. Blair was quick to respond and met me at my house to walk through the issues and solutions. The work was done on time, and the crew left the yard clean. The work was finished just before Florence, and everything worked great. I highly recommend Green Frog.

I had a wonderful experience with Andrew and his team. He came up with a plan to protect my garage from flooding and redirect water to a drain in my backyard. Everything works perfectly. The team was on time each day and cleaned up when leaving. Very professional all around.

Green Frog is THE BEST! I literally feel like the have dealt with our home as if it was their own. They are professional, responsible and the end result is something we have been super happy with. I am so thankful to have Green Frog to call for a variety of "homeowner needs"!

Blair and his team did an extensive amount of work at our home. Later, when we were selling our home, buyers wanted a lot of information on the work and Green Frog stepped up to provide details. They went above and beyond and we appreciate their professionalism. The systems they put in place have effectively controlled moisture under/near our home and we are confident that will continue to be the case for many years.

I have been crawling under homes for 13 years working in the pest control industry, and have seen the work of many moisture experts. I chose Green Frog due the quality of work and honesty that I have seen them give people over the years. I am very satisfied with the work they did at my house. I have been and will continue to recommend them both personally and professionally.

This company is FANTASTIC! Their service at my home was excellent and all their staff professional and courteous. Their pricing is reasonable. Blair helped me understand the water and moisture related issues that were occurring at my home better then any other contractor I spoke with. Green Frog performed a large project at my house. They encapsulated our crawl space and solved drainage issues in my yard and I could not be happier with the results. Whenever I had questions about the work they would provide timely answers to help me make necessary decisions. I highly recommend Green Frog Waterproofing to anyone in need of the services they offer.

Professional, polite, and knowledgeable. I received several quotes to address our yard drainage issues and while GreenFrog wasn’t the cheapest option, they offered the most detailed and inclusive plan to completely address all water issues. We are completely satisfied with the work performed by GreenFrog, not only has addressing the drainage issues protected our home’s foundation, the river rock walk way is a beautiful addition to our back yard and what was previously called “the mud pit” is now a functional, beautiful, and grassy play area for our kids. So thankful to have a backyard we can actually enjoy.

For anyone who thinks they need moisture control solutions for their home or business, please call Green Frog Waterproofing before you make your final contractor decision. Over a two-year span, I talked with FIVE companies, and Green Frog was the last one. They were the only one to correctly identify my basement floor as being a monolithic slab and recommended a beaver dam for waterproofing to keep the structural integrity of my basement intact. All FOUR of the other companies wanted to install an interior French drain, which is very invasive for my particular situation. It is scary that I had to call FIVE companies before I got the most knowledgeable one for the job. Green Frog looks at your entire property and not just the symptoms in one area. They are comprehensive, and the installers are friendly, contentious and hard working. If you need Green Frog to check something after installation, they respond promptly. I will only use Green Frog for moisture control solutions I may have on future projects and recommend them to everyone I know. Angela Berger Owner, Laurelwood Community Preschool

If you need any waterproofing work done, do not hesitate to call Green Frog! The company is honest and dependable and there were no worries with the job we had done. After our crawlspace was cleaned and sealed, it looked beautiful! Laura came by to check the completed job and even cleaned little bits and pieces of "stuff" on her hands and knees! I felt bad for her doing that and told her she didn't have to do it, but she told me that she wanted things left as they found them! Perfect customer service!!
