"We couldn't be happier with Dave's overhaul of our fireplace. His attention to detail, and commitment to excellence. We feel so lucky to have found him after another contractor flaked out on us. He came to the rescue & did whatever it took to get the job done on time and on budget. He is highly skilled and capable. Several times during the job he suggested things that would enhance the finished product. In doing so he created more work for himself. These upgrades probably added a full day of additional work. He didn't change the cost for the job, he just wants his customers to be happy. His attention to detail and cleanliness blew our minds. He spent a full day getting the room taped off to prevent dust from spreading throughout the house. A full day!?!? And it paid off when the work was done...we're not even hiring a cleaner. More than anything Dave's got a good heart, my wife and I genuinely enjoyed meeting and working with him. (Note: no AI was used in writing this review!)"

"professional and very quick!"

"Dave was very professional. He & his team took care my roof problem as promised on time."

"This company is easy to work also fast clean and good communication. I really recommend."

"I've completed previously several projects on my property with half a dozen different contractors, and I've never had an experience as poor as the one I had with Stella. 1. Subcontracted Work: Stella subcontracted 100% of the work to third-party contractors except for trash removal, which I'll address later. They likely hired cheap subcontractors and added a 20-30% markup for their own profit. 2. Lack of Communication: Communication was minimal. I was rarely informed about the next steps or timelines. 3. Unannounced Workers: Subcontractors (painters, electricians, carpenters, etc.) frequently showed up without notice and began working. 4. Billing Issues: Stella issued invoices for partially completed work and expected immediate payment. If not paid right away, they charged interest even though the work wasn't finished. 5. Final Advice: Save yourself 20-30% of the cost and a lot of headaches, hire a reliable local contractor instead."

"Mighty Dog Roofing did a great job fixing the rake and installing gutters on my house. Work was done in a day, work crew was neat and efficient. "

"Very impressed with Sprague, Mark was very knowledgeable and straightforward. Crew was first class closing roofing and Clean Up in four days and cold weather. Justin was terrific, personable and responsive, and was always on site or available. Crew and especially Foreman were excellent. I would recommend GF Sprague for a high quality Job, their technology and customer service."

"Called On top roofing for an estimate, it took several weeks to get back to us, got the estimate and agreed to have the work done. A few guy showed up one day and started working, we were not notified they were coming to work,good thing we were here that day. They did the job and left without ever communicating with us about the work. We did a walk around and discovered that some of the work was not completed. So called the company back and the owner came out to look at the job, he said it would be about another $100. To complete. We were not happy because this was supposed to be in the estimate we agreed on. The workers show up again unannounced and did the job. We then received a bill for $200. More, again this was not what was agreed upon when talking to owner. We were hoping to form a relationship with this company for future work, but that's not going to happen, there was no communication and even with a written contract they will somehow charge you more than agreed on."

"I recently had Ad Roofing and Siding repair and replace the vents on my roof and fix a leak, and I couldn’t be happier with the service. They arrived on time, worked efficiently, and delivered great value for the cost. The team was professional and courteous, and their customer support was excellent throughout the process. I would highly recommend them to anyone in need of reliable roofing services"

"Home repair gone wrong… Do NOT use Connell for any home repairs! If you do make that mistake, do NOT hand over your final payment until ALL work has been completed to your satisfaction. A large dead tree uprooted and fell on the corner of my house during a rainstorm in December 2023. It caused damage to my siding, roof and chimney. A neighbor came to look at the damage and suggested a company to repair the roof and siding. It was Connell Roofing. I had not used them previously and would NEVER use them again for any work! They told me it would take 4-5 days to complete the work. They brought in a dumpster and began setting up their equipment in June 2024. Things seemed to be good. I was working remotely so could monitor the progress. On day 1, I had a woman contractor ask if she could use my toilet. Then the next day the same thing. Then a man asked to use my toilet. I decided to call the head company and they told me that workers should be going to the bathroom when they leave my house for their lunch break. In the 7 days that they worked on my house, they NEVER left for lunch. They were there at 7:00 am and left around 7:00-30 pm. When I went downstairs to my kitchen, I several times witnessed male workers walking towards the woods on the side and rear of my property looking over their shoulders. Then I saw them at least twice standing in the woods on my property about 25-50 feet from my lawn urinating. I reported that to Connell. You would think that if a company was going to spend 5 days working at your house they would bring a port-o-potty. I can only imagine them defecating in my woods had I not been working from home. Who knows, they may have done that while I was not looking. I prefer NOT to think about it. They played a boom box super loud! Even with my windows closed and A/C on, it was noisy to work in my office. One of my neighbors actually moved out of their house on the 3rd day and did not return until after the work was finished. The workers worked too long a day. I am used to getting things done after work in the evening in my yard like mowing and gardening, but that was all but impossible with the crew working until 7:30 pm each night. To replace my roof, they needed to remove all the old nails. Although they used a tarp to catch them as they were removed, and a magnetic equipment on wheels to gather them each night, I spent the next several months picking up nails all over my yard which must have numbers at least 200! I have a 9 year old daughter who often runs in the grass barefoot. I could only imagine the hospital visit if and bill if she stepped on one and it went through her heel. I have a small mudroom in which I built a beautiful wooden bench that I stained. When the men came in to reside that area (it was previously sided by the former owner), I watched one man feel how smooth the bench surface was. The workers then proceeded to stand on the bench the next 2 days working without a blanket and scuffed the heck out of the surface! I had to sand it several times and recoat it, but the dents and scrapes will remain. All of my gutters and downspouts needed to be replaced. It sounds easy to put 2 pieces of gutter pipes together, but if your workers are not properly trained, and there is a lack of supervision and inspection by Connell, problems will arise. The day the gutters were finished we had a heavy downpour. I went outside to see how the new gutters held up. The one by the garage was gushing water out of its sides for who knows why. When I looked a little closer I could see that the pipes were connected backwards, so the top piece was outside the bottom piece. Had that gutters been inspected, the problem would have been noticed before it rained. Although the workers used a tarp to shield my front door while removing the old siding, they did not protect when they put the new siding up. I had scuffs all over my black door so it needed to be repainted. When Connell sent a painter, he was not a professional. He clearly missed spots with the brush, and you could see that he did not have enough paint on his roller when he rolled the paint on. I called Connell several times then and then months later to get it repainted again. A few days after he painted it, the paint started shipping off. I had not touched it, not had there been a storm, it just was not painted right. 14 months of excuses and my door remains unfinished. I wanted to delay a portion of my final payment at the end of work in June 2024 until my door had been repainted to my satisfaction, but was heavily pressured to pay every penny then, and was guaranteed that the repair would be made to my satisfaction and soon. The workers in the head office talk a good game and are great at making excuses for their workers’ work but are slow/unresponsive to fix problems. Final opinion: DO NOT USE CONNELL FOR ANY REPAIR WORK."
