Homeowner Reviews

“Alex MuscanellDevon Wells”

“JR is a good guy and very responsive. Mostly you are being let down by your gutter team, at least in my case.”

“The total experience was seamless from the selection of our Hardie board product, to installation. The entire staff was very professional and maintain communication though out the entire process. The installers are truly skilled craftsmen and are meticulous. After the install was complete, the only thing that was left was a Beautiful finished home.”

“I am unlikely to recommend the Unicorp Home Energy Service group that serviced my home.”

“Mr David Rohrer is available, courteous and efficien”

“Great job. Professional, efficient and caring.”

“Unicorp did windows replacement for us. They work in a professional and organized way throughout the process. The sales representative creatively looked up our house on Redfin or other MLS website to present an accurate quote for us. They installed 15 windows in one day, and kept our rooms (floors, walls, etc.) clean. The crew are easy to work with. The installation was in November, but because of the way they organize the installation process, our house did not get as cold as we initially thought. Highly recommend. b.t.w. They mark all the property that they have serviced on a map (somewhere on their website). I see this as a very positive signal that they are proud of their work, as I could directly ask my neighbors for reference.”

“I would like to recognize Alex M.”

“Don?t know any workers name. But the ones I Interact were very nice.”

“Brain W.”

“I was most satisfied with the quality of the workmanship, and the communication with the crew.”

“I would like to recognize JR, and the crew for their exceptional service.”

“The whole experience has been very pleasant. My roof was replaced by an excellent team. Any problem found was fully explained and permission to correct with an estimate was immediately presented. The workmanship was, to repeat the word, excellent, very clean and timely. Communication was tremendous and all members of the company are extremely polite. I couldn?t be happier.”

“Unicorp did an excellent job replacing the siding on my house. Very professional installation, and the work they did was very clean and tidy.”

“The crew was very proficient in what they were doing, and the finished product is excellent. The home looks beautiful.”

“A great experience from start to finish! Everyone was easy to work with, and great communication. The windows and door are fabulous, and the workers were terrific.”

“My roof looks fantastic and there were no problems - everything went very smoothly.”

“The entire process was good. The salesman was courteous, knowledgeable and patient. The installers were courteous and did a professional job. The windows are excellent quality. I did get what I was promised. I am a happy customer. Thank you.”

“The salesperson David Roher”

“I would recommend Unicorp HES for siding work, but would warn people to stay away from the gutters installation. Unicorp Home Energy Services did an awesome job installing Hardy siding on my house. Everything seemed fine, until the crew showed up to install the rain gutters. The crew did very poor job installing the gutters. There are places where the gutters are visibly bent or crooked (not by design). I made a mistake of purchasing gutter guards from Unicorp. I do not recommend this option for anyone. The gutter guards used by Unicorp have a huge design flaw. The holes of the many other gutter guard brands are oval like and wide enough to allow proper water flow. The gutter guards used by Unicorp, however, have small round holes. Those small holes work well with light rain, but heavier rain causes the water to overflow, which makes the whole gutter system somewhat useless.”

“Brian & Paul”

“Brian Weil, J.R. Burger and Mr. Cho”

“The craftsmanship met my expectations.”

“I'd like to recognize the CEO of the business.”

“High quality and great service!”

“They were all professional.”

“Brian, the CEO/owner, personally checked on our job and spoke with us directly. Grade A human being.”

“great”

“Brian Weil seemed personally committed to the success of this project.”

“Quick professional work, looks good, keeps the rain off”

“Paul was genuinely friendly and professional. He was an absolute pleasure.”

“Top quality windows and Hardee siding. Installers do great job.”

“Quality of workmanship, diligence, cleanliness of site area, ease of contracting process.”

“I would like to recognize Brian for his exceptional service. As well as one of the siding techs, I cannot remember his name. However, he was terrific, very responsive, and efficient.”

“I was most satisfied with the quality of the work. I really like them addressing the things that did not look just right. They came back to make sure we were happy. They went above and beyond and I really appreciate it.”

“I would like to recognize J.R., the site coordinator, and David, the salesman. The crew did a really good job. They worked as quickly as they could under bad weather conditions.”

“Alex M. and JR provided exceptional service.”

“We love the way our home looks. Our friends drive by and admire the siding, windows and shutters.”

“Not only are we pleased with the quality and appearance of the windows themselves, but were also very impressed with the job your installation crew did.”

“I used Unicorp to replace my windows and siding? I still can?t believe how incredible my house looks.”

“We are thrilled with the results. You and your employees delivered exactly what you promised.”
