Manufacturing & Fitting High Performance Windows and Doors For Over 40 Years.

Costello Windows manufactures every facet of the final product in-house from a 13-acre factory located in Glin, County Limerick. We have been in business since 1979. Costello Windows employs a set of 50 skilled employees. We have a specific belief that quality, innovation and service are vital to success, every day we look to improve.

Innovative Products

We measure, manufacture and fit all our window and door products which are designed to be aesthetically pleasing and to add a massive wow factor.

Costello Windows’ latest patented design is the Townhouse Sash Window. This window is designed in the style of a sliding sash window but opens in a different way. The Townhouse Sash Window does not slide up and down but rather the top sash opens out and the bottom sash opens in. This gives full fire escape access and ensures that the window has a compression seal.
