J.C. Tonnotti Window Company

J.C. Tonnotti Window Company is a family-owned exterior remodeling contractor that has been in business since 1979. It installs replacement windows in many styles, including double-hung, casement, bay and bow windows, along with entry, interior, patio and storm doors. The company also does siding, roofing, sunrooms and patio enclosures, and exterior painting, with its own in-house crews rather than subcontractors.

The company works across the state of Connecticut and handles a project from measuring and design through installation and warranty. Free estimates are offered, financing is available, and many window and roof replacements are finished in one day. The office is on Bristol Street in Southington.
