A. Ramos construction did a fantastic job. Roberto, Gonzalo, and the rest of the team were great to work with. Reliable, respectful, on time, and always communicated what was going to happen. Roberto kept in contact about changes in weather and letting us know what he found at each stage of the project. The price quoted was reasonable and the work that they provided was above and beyond. The quality of work and cleanliness of their team was pleasantly unexpected. Everyone was polite and professional. Any questions or concerns that we had were quickly addressed and taken care of. We will be hiring them again for all of our repairs and maintenance.
A Ramos Construction is a professional, Dependable company. We called them late at night and the owner Roberto Ramos answered and was very pleasant to speak with. I told him about our problem with the over flowing toilet that damaged 5 rooms. Right away he sent his guy Gonzalo Chayrez to meet with us with in a few days. Gonzalo was very friendly and professional, dependable. He pointed out somethings that he noticed that needed to be addressed to the insurance company. He spend over 3 hours really giving those rooms a good inspection. His report was 20 detailed pages long and included 80 pages of images to go along with that as well as his 2 drawings that he made into computer images of the layout of our home. I was very impressed with GONZALOS work. He was very friendly and went right to doing his job. He even shared pictures with me of other work that they had done on jobs as it's always good to see those images to be comfortable about work being done to your house. The images looked nice. I even checked out their website for more images. A Ramos has been the 2nd company to do a nice theral job! The nicest thing is we didn't have to wait long for our estimate during Gonzalos Chayez, busy schedule he was able to get it to us. If your looking to get a bid/estimate you can't go wrong with this company. We have been waiting to get this project moving for 3 months now. The insurance wanted 3 bids before they would settle. All three bids were pretty much on the nose for the damage done to our home. I want to Thank Gonzalo Chayez for doing a nice job! I wanted to post the drawings but no option for that. He measured and drew the upstairs and down stairs area. It is a nice drawing and explains things well.
Excellent service and above and beyond quality of work. Roberto is highly skilled in the work he does. They built a custom in house entertainment center for my home and I cant express how awesome and fantastic the quality is. I highly recommend using A . Ramos Construction for your next project. Ask for Roberto!

We recently completed a commercial project in the City of Niagara Falls with United Thermal Systems. I would like to commend the efforts of the entire company in with their professional mannerisms. From the initial start of the project, they were there to assist with their extensive knowledge of the foam insulation systems and the standard building code requirements, to assure a successful completion. When U.T.S arrived on site, we were immediately greeted by 3 gentlemen. They were highly professional in their mannerisms and their immediate knowledge of the scope of work & how they were going to proceed. They take great pride in their work, through any means necessary to accomplish it. Hard-working, dedicated & knowledgeable employees that work for U.T.S. Would highly recommend establishing a line of communication with Larry, to ensure that you will be getting exactly what your project requires. He will offer great assistance to your project needs & offers many suggestions to ensure a quality job from start to finish. Thank you, Larry.
Hard working, genuinely great people.
Great contractor to work with/for. Most experienced/qualified applicators in the area.

Hello, Thank you for insulating my home. I can feel the warmth. Out of all the years I have been here (30 +). I finally can be warmer. Words cannot express what I feel. Your company has an excellent team of workers beginning with the first two who showed up on Thursday January 28, 2026.. Boomer and everyone has done an excellent job. As a homeowner I am truly and honestly satisfied. my taxes has doubled this year. I am on a fixed income and cannot afford to do the repair that your company has done. I am reaching out to other agencies for help also. I highly recommend this team who has been here for me. This means the world to me. 💯 🙏👌

Excellent experience working with Evan at Hughesco! Evan guided the process with knowledge and skill. I’d rate 10 stars, if possible. The level of support was everything a customer seeks and needs. All questions were answered. Any concerns quickly resolved. Through Evan’s guidance, we were able to proceed with the NYSERDA’s electrical upgrade and heat pump dryer incentive, smoothly. It made an otherwise daunting and confusing process understandable and possible. So happy and highly recommend!!
Shout out to Justin for setting up this installation and making it all happen. The crew of Nick B, Nick C, Isaac and Orest did a phenomenal job on the installation. Absolutely professional, detail oriented and on time. Highly recommend this company.
Evan was a pleasure to work with, responsive and friendly and helped make the process for heat pump and electrical upgrade incentives through NYSERDA as smooth as possible. He went above and beyond to resolve an unforeseen issue with the new heat pump technology after it was installed and it is working great! Definitely recommend!

I was referred to MIG Insulation by a friend. Mike the sales person came and quoted the job was very professional and knowledgeable. I was quoted a good price. I was presented with a detail summary of what work would be done. Today the crew showed up Andy, Sean, Pete, and Antoine were courteous professional. Andy kept me informed step-by-step of what he was doing with the Insulation and resolving some vent issues. Andy was very knowledgeable, Thorough and precise on what needed to be done. I highly recommend MIG and it’s crew if you’re looking for professional first rate job.
I should start with fact that I'm a building inspector. I see every level of workmanship... or lack thereof. We bought a derelict house to fix up and help restore a neighborhood. We knew it would be an uphill battle. When we removed the drywall to insulate, it was apparent that every stud cavity dimension was different. Spray foam insulation wasn't in the budget, but it was the only viable solution. We obtained six quotes for the roof, walls, and band joists. Derek Minscher(?) from MIG gave us a quote, plus great advice and helped obtain a grant to offset the emergency in our budget. The crew they sent to apply the spray foam was amazing. George (pretty sure it was really Jorge) and James got straight to work, protected every surface and made certain conditions were optimal for the application. James sprayed and George made sure that there was no spray anywhere but where it belonged. These guys worked hard and efficiently- every move was measured. They worked steadily, politely and without comment or complaint. They were a finely tuned machine. I'm used to being underwhelmed lately, so getting this effort was a really big deal. After witnessing their professionalism, I had the same crew insulate an addition on my own home. I recommend, without reservation, MIG for closed cell insulation.
MIG helped remove and reinsulate my attic. They were fast and efficient. They also offer low rates and helped me keep the cost down. Derek was my rep and he was excellent to work with. Responded fast and was kind. I highly recommend their services. I will be using them again for my fireplace. Thank you MIG!
