Isai with American Group Construction is just wonderful. I first found Isai about 9 years ago when had a leaky skylight when we first moved in to our home (we bought >100 year old house). I went through about 20 contractors before I found Isai. He was the only one to actually get on the roof to check and found it was the roof, not the skylight, causing problems. His crew replaced the lower roof with new skylights in just a day. He also has a great guarantee on his services.When we thought we had a leak in the roof when it started pouring like a waterfall from the dining room, he came right out the next day to check it out. Turns out, the HVAC left a hole in the side of our house when HVAC guy installed a new unit upstairs (that is a whole other story). But Isai also determined that the upstairs roof had some issues that needed to replaced. Once again, his crew replaced the upper roof in a day and did a great job. He also replaced our garage roof at a later date.We then had a leak through one of the skylights that we replaced. Isai came out the next day. He determined that the skylight was fine but found that an upstairs window was leaking in water (whoever originally fixed up this house just literally put bandaids over everything and now everything was coming off). We saved up the money to fix our whole outside of our house. We needed a general contractor to do the outside porch/deck, mudroom repair, and stone foundation. Isai did all the siding, windows, and doors. Isai has made our house look beautiful - a red farmhouse type.Isai is great to work with, especially as a woman. I have had so many contractors treat me poorly or ignore me because of being a woman. But he treats everyone with respect. He is very detailed, reasonable, and gives many options. He was willing to work with us when we had hiccups and delays with the first general contractor (too bad Isai is not also a general contractor). He will fine tune until you get your vision. I now have my dream home. Trust Isai, Harry, and American Group Construction and you will not be disappointed.

I HIGHLY recommend American Group Construction, with Isai and his crews! We were recommended to Isai and his company from another contractor, and I'm very happy with this project and the results. I'll cover the phases of the process and discuss how we addressed challenges along the way:For our project, we needed to address leaky doors, high interior moisture penetration, and improper siding and water drainage. We replaced three exterior doors with brand new ProVia entry and slider, removed all existing siding, and replaced with 1/2-inch foam sheathing, tyvek wrap, window aluminum cladding, new shutters, and new vinyl siding:1) project initiation: Isai met with us several times to go through the project details, options, rationale for choices, and to confirm our materials order. We were very satisfied with the approach to upgrading our 1960's exterior as well as the old and leaky doors. Isai uses high-quality vendors, including ProVia doors (industry best), at prices that we found to be expected and fair.2) scheduling: initially, we were looking at a project start approx. 8 weeks after materials order. We collaboratively decided to delay our project several times, due to cold and rainy weather. Ultimately, we were very happy that Isai proactively worked with vendors and his teams to move the project dates, and once we started it went as-expected and on-time. One hugely positive note: Isai's team shows up reliably EVERY DAY! 0730 they were ready to go. I applaud this incredible dedication and professionalism.3) project work: Isai's team did great work, they very quickly removed the old siding, and got the new materials prepped and ready while installing efficiently! We ran into several issues with "field conditions" (existing state of the house), and worked through them while reviewing additional options and insights for how to deal with the problems - things like odd-shaped vents, or insufficient space to place things. One problem cropped up, where although I had warned the team about some fiber-optic cables on the exterior, they unfortunately got damaged. Isai promptly took responsibility, asked me to coordinate with the original vendor for repairs, and told me that he would cover the repair costs - this is true accountability!4) completion and wrap-up: as the project came to a close, and the finishing touches were being made, we clarified any last-minute items and ensured that the punch-list of small items was followed. Isai ensured that his crew made all the final details correct, and they cleaned up both the project debris and ensured that they removed nails from the ground with a magnet as well as by walking around and manually searching. Upon completion, it all looked new and stately!Overall, we are super pleased with Isai's team and the final result! When we encountered issues, his team worked to fix them right away, and are so happy that it was collaborative. If you need exterior doors, roofing, siding, and window work, CALL American Group Construction, and chat with Isai. He will truly wow you and you'll end up with an awesome result. Thanks!(pictures include some before, during, and after views)

The company replaced my shaker shingle siding with Hardie Board siding! What a difference it makes! The team was outstanding and they were meticulous and did a thorough cleanup every day!! I can not say enough great things about this company!! Timely, courteous, respectful and their team worked like a well oiled machine!

American Group Construction was recommended as a good roofing contractor. When the president of the company, Isai Fonseca, sat with me and explained the details of his estimate, I felt confident that the work they would perform would be expertly done with quality materials.Their team arrived early and did a wonderful job. They were professional and very friendly. They replaced some rotten boards under the old roof. They installed new drip edge around the entire roof as well as new flashing around a skylight, plumbing vents and chimney. And they installed a new gutter cover.I am thrilled with the job and the new roof looks great! I will recommend American Group Construction to anyone who asks.

We highly recommend American Group Construction. I found them through Angie’s list, because we needed to replace our roof. I called them on a late Saturday for a quote and they came the next day, on Sunday. They were the only company who agreed to work on my schedule. At the beginning, I had in my mind to do repairs only and replacing the roof in a couple of years, because my 3 previous quotes to replace the roof were too expensive for my budget. When Isai came he took several pictures of my roof, and his quote for replacing the entire roof was very, very, very affordable. Then, he explained to me the process and we discussed about any hidden damage that he could discover when replacing the roof, so everything was crystal clear. He found 5 damaged plywood, sent me the pictures and proceeded to replace them. After finishing the job, they gave me the certificate of completion for my insurance company, that lowered my annual insurance premium from $2800 to $928. We are very happy with American Group Construction, a family owned company, they were very professional, reliable, and with the lifetime warranty on my roof, we couldn’t ask for more. Call them, they will go above and beyond and you’ll end up with an extraordinary result. Thank you!
