"I had a fantastic experience with Greene Solutions! Every point of contact was professional, from office associates to the company's owner. I own an old house (100 years old) with knob-and-tube wiring. That old wiring threw a spanner in the works, i.e., the old wiring had to come out in order to install insulation. I had a devil of a time finding an electrical company to do this job. Finally I called Greene Solution's owner (I was in tears) and said I was giving up; no one would do the job. He told me he'd try to find a company while I was vacationing in VT. Well, when I got back, he'd located a company and my contacts with that company (Brett Short Circuits) were completely satisfactory. There were several phases to my project, and all went splendidly. The solar attic fan was installed and I'm very pleased. Basement ductwork was sealed (Aeroseal). My goodness! Positive results were immediate: I moved one entire category higher in efficient usage with both the gas and electric companies! The old attic insulation was removed before the electrical work started. Greene Solutions did this attic cleaning. What a dirty job! Given the age of my house, the workers had to contend with a mega-buildup of old coal dust. Yuck! The electrical company (Brett Short Circuits) then did the rewiring of my entire house. This was a huge job and I was completely satisfied with their work. The team of electricians assigned to my job was excellent, extremely hard workers. They were very conscientious about cleaning before they left each evening. They used canvas drop cloths to cover my furniture as they moved from room to room. Finally, they kept me entirely 'in the loop' re their schedules. I appreciated their courteous and respectful attitudes. Their work was approved and signed off on immediately by city inspectors. New wiring in place, the project then moved to the insulation phase of the project. Greene Solutions did this phase of the project. It took two days to get this job done. Attic, walls, and basement were insulated. This was another hugely dirty job, given the old coal dust in my house. For those of you who don't have experience with coal dust ... thank your lucky stars. It gets into everything (even wood grain) and it stays. This particular phase of the project took two days. I was very pleased with Greene Solution's team of workers. They were courteous, respectful of my space, and were heads-down workers. Another great team! Door installation awaits delivery of the doors. Of course, all had to be custom-made, given the age of my house. Greene Solutions will do this phase of the project and I anticipate no problems. I highly recommend Greene Solutions. I am very pleased with the partnership we forged as I took steps towards reducing my carbon footprint."

Muth & Company Roofing
Muth & Company Roofing
Since 1992, Muth & Company Roofing has installed the highest quality roofing systems for homes and businesses in Central Ohio. When it comes to product knowledge, customer service, workmanship, and warranties, no other roofing contractor can compare to us. It’s no wonder that we were the first roofer in Columbus recommended in Angie’s List, and we’ve had hundreds of rave reviews for 16 consecutive years! WHY WE’RE DIFFERENT Here’s what makes the Muth team stand out as local roofing contractors: •We’ll install your roof as if it were our roof. •We’ll treat you with respect as if you are a member of our own family. •We’ll review our innovative Pre-Work Checklist with you, so there are no surprises. •We won’t finish until you are 100% satisfied. 18 employees. We do use some subs for installation. Cost is determined by the job. Travel charges may apply. May contact through e-mail. Family owned & operated. Additional DBA - Muth & Co Roofing Inc. Award winning. Senior discount is 5% up to $300.
"We had a great experience with Muth & Company Roofing for our roof replacement project. Our sales contact was Kelly, He was excellent to work with all the way through the process. Regarding the demo, the crew took great care to protect my house and property while removing the old roof. They made sure all old materials went into the dumpster as soon they were removed from the house. I was impressed with the install crew too: Right tool for the right job by using a crane to lift the new materials onto my roof VS running them all up manually. They were very efficient and worked in pairs as they put on the new roof. Job was completed in one long day which impressed me as i thought for sure it would take more than a day to complete. The GAF Timberline UHDZ shingle with the extra shadow line is a huge improvement from my old shingle. Really makes my house pop. We love the improved curb appeal of our house with the new roof. The crew made sure to clean up before the project was completed and Brian our project manager even did touch up painting for me. Hard to tell they were even here! Overall, clearly a 5 star performance!"

"Wonderful experience from start to finish. They added insulation to our upstairs attic, wrapped the attic space above our garage, and sprayed foamed our basement. Very pleased with the end results! The loft located above our garage has significantly improved. The room and the floor itself were always too warm during summer months. Now it’s like a whole new space. Our son uses the loft as a playroom and it’s an area our whole family can enjoy. Additionally we had a humidity issue in our basement we couldn’t figure out. Other companies wanted to install large dehumidifier systems which would’ve cost thousands. It felt like they weren’t even looking at our basement just simply suggesting the most expensive service. Then we met with the Edwards/Mooney rep and that all changed. He seemed very honest and trustworthy. He pointed to an area of concern in our basement and was confident spray foam would seal the basement and resolve our humidity problem. He was right. While workers were removing our old basement insulation, they found daylight where outside air (not to mention bugs!) were likely getting into our home. Once they sprayed foamed the basement, our dehumidifier numbers dropped significantly. It was a drastic change and we’re so happy the issue was finally resolved! We are extremely grateful for this company’s honesty as well as their service. We would definitely recommend them to our family and friends."

"Absolutely terrible! Worked with them on a $14,000 home A/C project that they botched. They caused damage to my house and didn't finish the project but proceeded to charge my credit card for the full amount without even contacting me. I then tried to contact them several times but they ghosted me. 1) They sold me on a unit that was 3X bigger than what I could have possibly ever needed. 4 tons for 1300 square feet. 2) They failed a city inspection because of poor installation and charge me for the reinspection. 3) Incredibly sloppy work. See photos. That is how they left it. Messy, unsealed holes into the house, damage to building... 4) Their installer put a nail through a wire causing $1,200 in rework that they refused to pay. 5) When they were finished, the A/C was installed in a way that shook the entire house causing dishes to rattle as it ran. Please avoid. These guys are unprofessional, disrespectful, dishonest, and simply not good at what they do."
