Keller and sons repair my roof about 14 months ago (great job) and I just recently had some wind damage to an area that was close to where they had been working but did not need replacing at the time, I contacted Keller and sons and informed them of my situation the next day I was contacted by both mike and dan Keller letting me know someone will be out the next day to make my repair NO QUESTIONS ASKED!!!!! The next day my repair was completed free of charge. It’s nice to know there are some businesses still doing business the old fashion way. Thanks Keller and sons. John hopatcong nj

Roof was 25 years old and was due for replacement. I also had old LP fiberboard siding that needed replacing in some sections mainly the chimneys. The rest was ok and I couldn't see spending the money to replace it all. George Keller did a terrific job on the roof and worked with me to match the LP siding using James Hardie siding. Carl the estimator took his time gave me a detailed estimate with pictures showing all the sections of siding that would be replaced. George Keller had done other houses in our neighborhood and one neighbor, an architect, used them, so that speaks to their reputation. I would highly recommend them. They are very efficient and neat and will finish your job in a day or two.

I am rating these guys a D because of the way they handled the quote and scheduling of my job. The actual work they did was great. I had used them in the past to have my roof replaced and that experience was fantastic, so I went with them again to repair rotted trim and replace my gutters prior to having my house painted. Carl came to do the estimate in June, and I walked him around to show him generally where the damage was, but was very clear that I wanted any and all rotted trim and gutters replaced before I brought in painters, who would be coming in right behind them. A few days later he emailed me a quote that had a laundry list of items to be repaired. Shame on me, I didn't walk around my house and reconcile everything that was on the quote to everything that was damaged, I trusted that he had followed my instructions, and had quoted me for all the damaged trim. Now the fun begins. I paid my deposit in June, and it took until the second week of August for the trim crew to show up. Within 5 minutes, the foreman was at my door telling me that there several damaged areas not included in the quote, but not to worry, he would take care of it, wouldn't be that much more. I said OK, because I had already scheduled the painters for the following week. When the revised estimate came back, it was $2800 more for two corners of my garage and one piece of rake (fascia). This was half what the original quote for all the damaged trim was, and there was still more that wasn't included. After a couple of angry emails, I finally got them down to only $900 more (still not happy), but ended up fixing the remaining damage myself (two full corners of my house and a piece of soffit, all of which I had pointed out to Carl) so that the painters could finish. Total cost for me to do it...$125 in material and 6 hours of work. On top of all this, my understanding was that the gutters would be done right after the trim, so I scheduled painters in mid August. Wrong. The trim was done in early Aug, the gutter crew didn't show up until early September (again, after several angry emails), so I spent a month and several thunderstorms without several gutters/leaders, and water pouring down the sides of my newly painted house. And now I need to go back and paint where the other leaders were removed, because different hardware was used for the new leaders. Icing on the cake was that after everything was done, it took another two weeks (and more emails) to get the 16' pallet of extra material out of my driveway. Long story short, I could have done most of the trim myself, but I brought these guys in because I am 50+, and don't want to be hauling and scaling to the top of 32' ladders anymore on my weekends, but that is exactly what I ended up doing, twice. Once to fix the trim they left out of the quote, once to repaint parts of my freshly painted house. Its a shame too, because I have a bunch of windows that will need to be replaced in the next year or two, but after this debacle, someone else will get the job.

Received excellent service and a high-quality siding installation from George J Keller & Sons. Our historic home has cedar bevel siding, which had failed prematurely due to another provider’s poor quality materials and workmanship. We hired G J Keller to replace the shoddy installation we had inherited, and to “do the job right” with new cedar material, which is precisely what they delivered. From the initial consult meetings/proposal, through the the scheduling, installation, closeout and cleanup, my end-to-end experience with G J Keller was top-notch. Every interaction I had with the team was a pleasure; with Dan (proposal/contract), Jaime (back-office/scheduling), Ray (project manager), Jesus (crew foreman), Mike (senior installation expertise). There were a couple challenging/tricky installation details on our job, and I felt those were handled by Mike/Ray very thoughtfully, patiently and creatively, with a high focus on making sure I was going to ultimately be satisfied with the end result. Across the board I found the entire staff to be accommodating, competent, responsive and communicative professionals who delivered a high-quality install, with great customer service, at a fair price. Highest marks to Dan, Mike, and the extended team at GJ Keller. Would strongly recommend to others, and would use again myself, without hesitation.

Hi [Member Name Removed] - Thank you for leaving this review. After researching your review I found out that I have not been receiving the email notifications from Angies List since May. I spoke with my Angies rep and our notifications has been updated. I was also informed from my rep that Angies List now has an app for iphones. I downloaded the app and now have immediate access to any Angies List information. Thanks, Dan

George J. Keller is a very professional company that stands by its work. We had leak the day we took over our new home. They sent someone out very quickly and did a repair to stop the leak. We later used them to install a new roof. They did a great job with the installation and all the trim work. They stand by their work making a small adjustment when needed and inspecting the roof for a leak that turned out to be masonry.

They have done an excellent job on the roof! The estimate was detailed and included pictures to highlight the roof issues. Other estimates were just a vague list of estimated costs and couldn't tell if they were going to resolve the roof issues. The team was responsive and the work was done beautifully. They did an excellent job with cleanup and we could barely tell that they were even there. Highly recommend them.

Dan came for the initial estimate. Went up on the roof and inspected the condition. Gave a presentation of the three different options on his tablet. Showed initial pics of troubled areas. The three options differed in the type of underlayment used in the roofing process. Installation day went smoothly. Mike and crew was punctual and there was no hiccups. They were able to complete the job in one day. Clean-up of the nails in the yard initially was ok. I went to a local hardware store a bought a $10 magnetic sweeper and found about 50 nails and a broken saw blade. I called the next day and Mike came back immediately and did another sweep of the yard. I would recommend going out and buying a cheap magnetic sweeper and every few days do another sweep. Granted there was probably 10,000 nails and they did get 99% of it. In the scheme of things this is a minor issue. Overall the roof looks great and the office personnel were wonderful to work with as well.
Description of Work: Total roof replacement [two existing layers] on a bi-level house. Installed ridge vent system. Added two new bathroom vents and flashed pipes and chimney. Also added 12 soffit vents. Removed two old satellite dishes. After tear-off had to replace 4x4 foot area that was rotting.

George Keller is great, he did a great job. I don’t remember their cost, but it was reasonably priced. They were just professional, responsive. They worked with us in creating a solution. They didn’t have to do nothing like replacing our whole roof. They came out and did the job quickly and did it right. We haven’t had to call back.

Our house was re-roofed in July 2016 by George J Keller & Sons. We had estimates from 7 roofing companies and felt most comfortable with Keller. We felt Keller was the most honest because they didn't try to low ball the work. Our roof had been leaking on and off so my husband walked the roof and knew that we had some warped and/or soft sheathing. The other companies that came out told us only 3 to 4 sheaths would require replacement but we knew there were many more. We didn't want to select a roofer who wasn't honest from the beginning, Our sales person was Mike Koty and we liked him from the beginning. He went into the crawl space to check the interior condition of the roof which was something the majority of the other roofers didn't do. He also walked the roof. We had tons of questions and he answered each one fully and completely. The work took almost 2 days because there was so much sheathing to replace and, yes, they did show (without us asking) the rotten/warped sheaths. The workers were all professional and quiet and there was no debris left after the job was completed. The roof looks great and there are no more leaks. Just an excellent job from start to finis ...in fact, my neighbor was so impressed, he just had Keller reroof his house.

From the minute I called for an estimate till the time the job was completed these guys were great. They worked with me to schedule a date to start the job and they were here at exactly 8:00am the day of. There were 6 guys that showed up. 4 guys were always on the roof and 2 guys were on the ground constantly cleaning up. They wrapped my house in tarps and none of my shrubs or items were damaged. In about 1.5 hours they had my old roof removed. I then walked on the roof with Mike (whose the roofing crew supervisor) and noticed that 2 panels had to be replaced. Mike also said that he would have to remove at least 2 rows of siding to properly put the ice barrier shield under it. This company cuts a groove into your brick chimney to properly seal the chimney which I found out not all companies do that. They ice wrapped a majority of my roof and started putting on the new shingles. At around 4:00pm the job was done and completely cleaned up. Since my siding is older, Mike did not want to install the siding back on, but wanted me to have it done by their siding crew. The next day it rained so the following day, Dan and his siding crew, arrived at 8:00 am on the dot and within 3 hours had all my siding back up. Both Mike and Dan were great and answered all my questions. I believe this company went above and beyond to get the job properly done. I would definitely recommend this company.

George J. Keller & Sons was highly recommended on our local community Facebook page. We received excellent service during every step of the process. They were good to work with, did quality work, and we would be comfortable recommending them to family and friends.
Description of Work: Removed existing pitched roof shingles from the entire house except for the rear upper low slope Liberty roof. Installed ice and water shield on all gutter edges extending up the roof surface 3 feet and where roof meets side wall of the house. Installed GAF algae resistant shingles, ridge caps, and new pipe flanges on all roof plumbing vent pipes. Built cricket behind the chimney and installed copper flashing on chimney. Removed all debris and walked around the entire house with a magnet to pick up any loose nails.

I am overall satisfied with the work except couple points. 1) The installation dragged out longer than expected. I signed purchase (not lease) contract in early December 2015 and was expecting it to be done in March. Instead, it was done in the end of April. I didn't receive any status updates unless when I inquired. While I understand the permit process could be out of their control, better communication would had been helpful. 2) The installers are not from George J Kellers & Sons. The contracted the actual installation to someone else. I am neutral about their work. I found nails on the driveway, and I said to the head person please be careful not to leave any nails since I have a baby running around outside. I had to pick up more nails in the afternoon myself. They were ok, not great, not bad. My dealings with GJK after installation has been smooth. They scheduled inspection, and informed me when the meter will be replaced by the utility company. GJK's meter (tied to the solar control panel) broke, and they promptly ordered a new one (although not yet arrived). I rate them A overall.
