EJ Pro Construction is a Marlborough contractor focused on window and door installation. Thumbtack describes two years in business, 70 projects or media items, and window, door, and floor installation; BuildZoom places the company at 145 Pleasant St Apt 303 and lists Massachusetts HIC license #213000 as active in its directory. Recent Thumbtack customers repeatedly describe replacement windows, patio doors, rotten-wood repairs, trim, and careful cleanup. They mention Harvey windows, a ten-window porch project, a 29-window-and-sliding-door installation, and a storm response in which the crew quickly covered a shattered basement opening before replacement. Before booking, confirm the license directly with Massachusetts and spell out whether rotten-wood repair, exterior and interior trim, materials, and disposal are included. EJ Pro looks best suited to residential window and door replacement, including projects involving damaged framing; get the product specifications, warranty, and installation schedule in writing.
I would give EJ Pro 10 stars if that was possible. Enoc gave me an estimate which was much more reasonable than other contractors. His installers are professional efficient and cleaned up every day they were at my home. The windows that were replaced were quite old and the EJ Pro team installed Harvey Windows on my 3 season porch, replaced rotten wood, and used vinyl to frame all 10 windows inside and outside. I am so happy with his workmanship, the finished result and the job he did for me. Highly recommend
Enoc and his team did an amazing job replacing my two windows and patio doors from rotten wood frame to more modern looking construction.
I couldn’t be happier with the work EJ Pro construction did at my house. The team installed Harvey windows with exceptional craftsmanship and attention to detail. Every window was installed perfectly, and the quality of the workmanship exceeded my expectations. They also completed the delivery and installation ahead of schedule, which made the entire experience even better. From start to finish, they were professional, reliable, and clearly took pride in their work. I’m beyond satisfied with the results and will absolutely be hiring them again for future projects. I highly recommend them to anyone looking for top-quality window installation.
I wish I could select every category: Work Quality, Value, Professionalism, Punctuality, and Responsiveness—because Junior and his team excelled in all of them. From day one, Junior and his crew showed up on time and delivered exactly what they promised. They worked tirelessly for three extremely hot days to install 29 windows, including a sliding door, and their craftsmanship was outstanding. They bring exceptional skill and experience when it comes to window and door installation. They even wrapped the exterior with aluminum trim to protect the exposed areas from future rot and weather damage. The attention to detail was impressive. They left the job site spotless, both inside and outside, at the end of each day. One detail I especially appreciated was that Junior carefully installed the interior trim to allow for seamless cordless blinds to be mounted perfectly afterward. The finish, both inside and outside, was clean, precise, and high quality. Their pricing was also very competitive compared to the large national window companies. In many cases, those companies simply subcontract the installation to experienced crews like Junior’s anyway. By hiring Junior directly, you get the same level of craftsmanship, warranty, and quality installation while receiving more personal service and better value. I highly recommend Junior and his team. They exceeded my expectations, and I would not hesitate to hire them again in the future.
Praised Junior and his team for on-time installation of 29 windows and a sliding door, careful aluminum exterior trim and interior trim, spotless cleanup, competitive pricing, and excellent craftsmanship.
