Sean Decker and his team did an amazing job. He fit us into the schedule so quickly and was a pleasure to work with. Our steps are now safe and look great!Posted on Matthew FratelloTrustindex verifies that the original source of the review is Google. Sean & his crew replaced my front door and porch. Sean was honest and kept me up to date and was always responsive to any questions I had. I could not have been happier with the work that was done. I highly recommend. Thank You Sean and Crew.Posted on Bill EtzelTrustindex verifies that the original source of the review is Google. Sean (and his crew) go above and beyond every time I've used them. Work is meticulous and precise. Clean up is outstanding. His "can-do" attitude is infectious. Will use his services every time !Posted on F DeckerTrustindex verifies that the original source of the review is Google. We had Sean install a much needed handrail on our back stoop. We didn’t want wood because we didn’t want to have to paint it. Sean suggested Trex and we had a nice selection of colors and styles. After 2 days, Sean completed the project and it was beautiful! We were surprised how it changed the whole look of the back of the house. It really has enhanced the look of our craftsman home. We are very satisfied with Sean’s design ideas, suggestions, work ethic, meticulous workmanship all at a reasonable cost. We will be calling Sean back for our other planned projects.Posted on Wayne BellucciTrustindex verifies that the original source of the review is Google. Words cannot begin to express how happy we are with our new front porch. We have done several large home renovations in the past year, Sean Decker and his team were by far the most professional and enjoyable to work with. Sean is professional, punctual, courteous and an excellent communicator. His attention to the details and finishings were above and beyond. The porch was completed ahead of schedule. My only regret is not knowing about him sooner! If you are looking for home improvements or decking, Decks by Decker is the company to contact. You will NOT regret it.Posted on Nicole HayesTrustindex verifies that the original source of the review is Google. Decker and his crew did a phenomenal job on our deck! Their work completely exceeded our expectations. We met Decker for an estimate a year ago for this project. But based alone on his professionalism, honesty, expertise and innovative ideas we immediately recommended him to my mother for a deck project which is just another glowing review. Fast forward a year later when we were ready to get started, Decker was considerate of our budget, honored the timeline and was responsive throughout the whole process. He arrived with his crew on time everyday until the job was done and they finished 2 days early! We are so grateful for their hard work and attention to detail. They went above and beyond to truly make sure we would enjoy the deck by doing a great job cleaning up and even taking a HUGE pile of broken fences that was near the deck to the dump for us!!! We honestly couldn’t be happier and look forward to more projects with Decker!Posted on Patricia MartinezTrustindex verifies that the original source of the review is Google. Sean and his crew built a beautiful deck, we were very pleased how it turned out. They were always respectful of our property and cleaned up every day they were done. When the deck was completed they even washed down the entire deck. Sean was professional and always responded to my texts or calls. If you need a deck call him, you will be very pleased.
