Addon Construction LLC

A recent customer said Addon Construction replaced their roof and put on new gutters, and that Chris and his crew communicate very well. The company says it serves Hooksett, NH, and the surrounding areas, and its BBB page shows an A+ grade and accreditation. A 2025 customer said the company helped with a roof leak repair and installed Hardie siding on their house. A 2025 customer said the company did an addition on their house. A 2023 customer said Chris provided pictures of where the roof was damaged and the options to repair it, and left the area very clean after the repair. A 2023 customer said the company sided their home and built a front porch, with Chris keeping them informed when getting materials was hard. A 2022 customer said the team tarped the house and cleaned everything during a re-roofing replacement job. A 2021 customer said Chris followed a verbal quote with a formal quote by email within an hour, and that the roof cap repair was completed within a few hours once started. A 2025 customer said the crew sent to install their Hardie siding had admittedly never installed it before, and that a roof the company did needed to be immediately redone upon finishing due to poor workmanship. That 2025 customer said a promise to come back and fix each issue was made a year earlier with no return visit, and that they were charged far more than the original quote. A 2024 customer said the crew installed drywall where they had asked for a pine ceiling, and that the cork flooring was not installed correctly and bubbled. That 2024 customer said Chris never showed to do the punch list, including a $500 propane hookup that ended up costing an additional $2,000 from a separate contractor. A 2021 reviewer complained of a total lack of communication over a bid and disputed being told their 14-year-old roof needed replacing. A 2016 customer on Angi said the work was good but a one-week project missed its schedule by a few weeks.
