Bespoke uPVC Windows in Lancashire

At 313 Glass, we've fitted thousands of windows across Lancashire, making Lancashire homes warmer, quieter and more secure. Our range covers every style for everything from characterful stone terraces to coastal properties and modern estates — casement, sash, tilt & turn, bay and bow. Lancashire's varied geography from Pennine valleys to the Irish Sea coast brings diverse weather. All windows are internally glazed for maximum security.

The difference between good and great windows is in the details. In Lancashire, our fitters obsess over clean finishes, proper drainage and weathertight seals.

Lancaster's central streets carry significant Georgian and Victorian stock, much of it within the city's conservation area, alongside large 1930s and postwar semis in Scotforth, Bowerham and Bulk.

Whether you're in the LA1 part of Lancashire or just outside, our team is set up to survey, manufacture and fit windows without hand-offs.

Housing stock in this part of Lancaster has unique traits. Quite a few homes have had their original front bay altered structurally at some point, so a "like-for-like" replacement isn't always possible without minor adjustment.

A common job pattern here is replacing one or two failed sealed units while the customer plans a wider upgrade — we're happy to quote in stages.
