We had an emergency situation when our roof was being replaced—the condition turned out to be much worse than expected, with rotten rafters and wood that all needed to be replaced. With rain expected the very next day, the company immediately took control and handled the situation without hesitation.In a time where many contractors don’t show up or don’t follow through on what they promise, this company was the complete opposite. They showed up when they said they would and got the job done right.One of the owners, Achilles, personally came to explain everything clearly to me and my husband. He made promises—and more importantly, he delivered on every single one. I have honestly never seen such a fast and professional response from any contractor.Achilles is a wonderful person, and his leadership truly showed during this stressful situation. The entire crew worked incredibly hard and were always respectful and professional.What impressed me the most was how they handled the emergency. On the very first day, they made sure our home was secure and safe, which gave us real peace of mind.I highly recommend this company to anyone looking for reliable, honest, and responsive roofing professionals.
Response from the owner: Thank you so much or your heartfelt review and for trusting us during such a stressful emergency! We're incredibly grateful that our team stepped up quickly to handle the situation, especially with rain on the way.A special thank you to Achilles for personally explaining everything and delivering on every promise-- its feedback like this that motivates us to keep going the extra mile. We truly appreciate your kind words and are thrilled everything turned out right. Best regards, The Seci Construction Team

Although I’ve already written a superb review of SECI, I think a follow up is in order, having lived with the roof they rebuilt in the summer of 2024. We have an antique house, with an 18th century foundation that was rebuilt in 1880, and then added on and updated in the 1960’s. What we thought was going to be a change of asphalt shingles turned out to be a major overhaul as the previous roofer had not removed the original wood shingles and they and the rafters underneath had rotted and also ruined the insulation. So essentially SECI rebuilt the roof, removing all rotten materials, installing good and new insulation, and making sister rafters (doubling) for the old ones, as well as new premium GAF TImberline HDz asphalt shingles. We also replaced 11 Skylights.Over the almost 18 months since completion, we have had a much more silent, solid house. Cooler in the hottest days of summer, and cozy and warm today in the coldest day in years. We had assumed that “this old house” was subject to drafts and exterior noise. WRONG! SECI has changed not just the exterior appearance of our house for the better but also markedly improved the quality of our lives. I might add that all their workmen were courteous, polite, respectful, and took care for us to have the least inconvenience during a major construction project. The manager Cobra and construction supervisor Manny were always courteous at our beck and call-and have remained so for any questions.
Response from the owner: Hi Kenneth, Thank you for the wonderful review and all the kind words. We appreciate your business and for allowing us to work on your beautiful home. I will Relay the message to the team! Thanks- Seci Construction, Inc.
