What We Do
Life’s Too Short for Window “Panes”
From energy-efficient systems and Passive House designs to historic window replication and full building-wide replacements, WindowFix brings expert craftsmanship to residential, commercial and architectural projects. We also supply and install storefronts, curtain walls and window wall systems.
Installations
Premium window and door installations by certified technicians, customized to meet code requirements for residential and commercial properties.
Repairs
Window and door repairs backed by a deep inventory of hard-to-find parts and glass, from spring balances to safety hardware.
Replacements
Windows last 25 years or more, but high energy bills, condensation or rotting frames can signal it is time. We restore comfort, efficiency and performance.
Landmarks
Experienced with NYC Landmarks Preservation Commission filings, we deliver code-compliant windows and doors for safety, sound, fire and energy performance.
