Comments: Johns Roofing Siding and Windows recently replaced our old roof, windows, siding, and gutters. Their work & work ethic is spectacular! The price and product warranty cant be beat. All work far exceeded any expectations we had, and the finished product is absolutely stunning. They were always accommodating to any thing we asked of them. All work was immaculate, and each day the crew did an excellent job cleaning up all work areas. We have future work that we will be having them do because they are simply the BEST!

Comments: John's work was well done, finished on time at quoted price. Crew was very efficient and worked very and clean. New roof solved an on going problem with roof leak on the porch roof. New gutters were also installed. I would hire John's company for any future projects.

Comments: John is professional and friendly. He arrived on time for the quote. He sourced replacement siding that was an unbelievably good match for my 20 year old original siding. He was on time for the job and finished early. His installation was top quality. I give him top rating and strongly recommend him.

Comments: In the many years I have been a widow, and one who stands on her owntwo feet, I have been overcharged and not well served to the extent I s toped trying get help and "did for self". :John" was the most surprising, pleasant, competent person I have met. In an area of 62 300K and up homes many others have been of the same opinion.g MY GRANDSON FOUND THE BUILDR HE USED FOR HIS NEW GARAGE THRU YOU; WHEN I NEEDED HELP (HE CANNOT DO HIMSELF BECAUSE IT REQUIRED AN EXTENSION LADDER ETC) HE REFERRD ME TI TIO YOU. JOHN CALLED ME AT ONCE; HE CAME EARLY THIS MONRING QUOTED A PRICE I ACCEPTED AT ONCE AND MADE THE REPAIR IN SHORT ORDER. I WILL HAVE NEED OF HELP "COME SPRING" DUE TO MY HAVING BEEN IN AN ACCIDENT SO CANNOT DO ALL M YOWN WORK AS USUAL; PAINTING AND SO ON. I WILL MOST CERTAINLY CALL HIM. MRS DUTTON; ELLINGTON

Comments: We were very satisfied with John and his team. They were all very courteous and very professional. I would highly recommend them to anyone. They were very neat and left no signs of our roof repair anywhere on our property.

Comments: Had John in about 18 months ago for a vinyl siding repair. He was very prompt and extremely reasonable on the price. Had a minor issue crop up yesterday and I called and he was at my house this morning to address the problem. Very please with the work and the responsiveness.

Comments: John and his crew were very professional and always on time. Their work was admired by all my neighbors and family and I hope he gets more business out of this as well. He not only did my roof for my house and garage, but he installed 20 replacement windows and 3 exterior doors for me and the price was great. My house looks so new now thanks to John. Great company.

Comments: I thought I had an ice dam and my garage ceiling was leaking. John came right on time, very professional and knew right away that it wasn't the roof but the furnace. Being a recent widow, I was so impressed with him, he took time to answer my questions, guided me what I needed to do. John, i found your other business card (i was so out of sorts I couldn't find the first one he gave me) and my father took it - he was so impressed too - I highly recommend John! I plan to hire him in the spring to do my ceiling in the garage. John is a man you can trust.

Comments: Excellent service

Comments: I was very happy with the work John and his crew did to repair my roof. He initially came to give me an estimate on the work but between the weather forecast calling for heavy rain tomorrow and a last minute cancellation from one of his other customers, John gathered his crew and got the job done on the same day! Can't ask for better service! And now I won't have to worry about another ceiling leak when in pours tomorrow. Thanks so much!

Comments: Great price great service, courteous and respectful. Great start to finish. Would use again and highly recommend

Review Date: 03/28/2015 | Author: a Neighbor

Comments: Even though they were prompt and did good job they cheated with the materials. We agreed on buying 6 bundles from home depot. When I was away, they started working on the roof and they used some third grade materials and they had no receipts for the materials. Further they only used 3 or 4 bundles. If you are not buying the materials dont trust these guys otherwise they do good job. They still did not send me any receipt for the work done and also for the materials that they is an update to what I rated before (0.5), like I said before they were here quickly and did good job. I got all the receipts now and looks like they spent little bit more than what we agreed before for the materials.

Comments: John came within 30 minutes of my call. He and his worker thoroughly removed all the snow/ice/ice dams and tarped my roof. The leaks have all stopped. We will definitely hire John again in the future - excellent work!

Comments: John was extremely responsive and prompt when handling an ice dam with our roof. He called me within an hour of my request for a quote and was at my house shortly thereafter! He shoveled off the snow during a blizzard, at night to make sure our leak was taken care of and helped recommend future action.

Review Date: 02/09/2015 | Author: Scott D.

Comments: john came out on a Sunday morning, a little over an hour after calling. He was up on my roof, cleaned it off, fixed the vent, and was thoroughly pleasant. The leak seems to have stopped, all looks good. I would call him again.

Comments: John and his group were easy to work with. They were able to finish the project in less than a week and managed to do a great job with everything. There was excellent communication and he knew exactly what to do. I would HIGHLY recommend him to do any job. My family was very happy with the way things came out.

Review Date: 12/03/2013 | Author: Christina F.

Comments: John and his crew worked so hard throughout the entire job. They had to remove 2 layers of asphalt shingles and the original layer of cedar shingles, put down plywood and then re shingle. He put new flashing and new gutters. He was the only quote we got that recognized that the roof would no longer meet the house shingles and he was prepared to solve that problem.

Comments: John from Home Improvement was prompt, fast, and fair in all areas of his business on the project.

Review Date: 04/20/2013 | Author: Bob S.

Comments: John returned my calls promptly, unlike many contractors today. He even came out the same day looked at the job and called me with an estimate. The job was in Connecticut and I live in another state and couldn't be there for another week. John showed up and completed the job when he said he would and to my complete satisfaction. I will definitely use him again.

Review Date: 05/19/2011 | Author: a Neighbor

Comments: I was pleasantly surprised that the job was done so fast. They cleaned up after the job was done and did not have to do it myself as it has been the case with other home improvement people in the past.
