Areas Where We Provide Solar Diagnostics and Maintenance

Serving Westford, Lexington, Andover, Dracut, and Nearby New Hampshire Towns

Sun Diagnostics Company is based in the heart of Middlesex County, with our main office in Westford, Massachusetts. We focus on a select group of communities: Westford, Lexington, Andover, and Dracut. These towns have many older solar arrays that need skilled diagnostics, repairs, and re-roofing support. By concentrating our efforts locally, we can respond quickly to urgent issues, whether it is a leaking roof after a Nor’easter or a sudden equipment problem in the summer. We know the unique needs of homes in these neighborhoods, from historic Lexington properties to newer solar installations in Andover. Limiting our service area means every client gets direct owner involvement, fast response, and careful workmanship. Our reputation among Middlesex County homeowners, especially those with solar systems over a decade old, is built on trust, technical expertise, and a commitment to getting the job done right the first time.

Our service extends into select towns in Southern New Hampshire, including Nashua, Salem, and Pelham. Homeowners in these areas benefit from the same high standards that define our work in Massachusetts. As solar systems age and warranties expire, many find it difficult to get reliable repairs or re-roofing. Sun Diagnostics fills this need by offering manufacturer-certified diagnostics, safe module removal and re-installation, and watertight hardware replacements. We never use subcontractors, so every project is handled by our own trained team, ensuring clear communication and technical accountability. Whether you live in a classic Westford colonial or a modern Dracut home, we bring a restoration-first approach to each job, protecting your investment and your property. From urgent leak repairs after spring storms to annual performance checks before summer, our service areas are chosen to provide prompt, dependable help where it matters most.
