Common FAQs About Sash Windows in Leicester

What are Sash Windows?

Sash windows are a traditional window design and consist of two vertical panels (sashes), one placed in front of the other. They slide up/down smoothly via counterbalance springs or weights, creating authentic period style with excellent ventilation and light.

Can I Use Sash Windows To Make A Bay Window?

Yes, absolutely. If you’d like to combine several sash windows into a bay window configuration, we can certainly help with that.

Are Sash Windows Different To Casement Windows?

Sash windows slide vertically for classic heritage styling. Casement windows hinge sideways like doors for maximum ventilation. Sash suits period properties in Leicester, whilst casement fits modern homes better.

How Much Do Sash Windows Cost?

uPVC sash windows in Leicester cost £550-£1,200 per window installed (supply + fit), depending on size, glazing, and custom features like woodgrain finishes or Georgian bars.

Professional, skilled, great communication from the on-site team - honestly, the best workmen I’ve ever had. They left the place tidy and neat. Thanks guys! They did a great job on a dreary, winter’s day with a smile. I love the new porch, which was a decent price. Honestly though, the sales guy Tom and the crew of Cal, Jake and Aaron were great. After having had a bad experience before with a different company, I’ll be using Phair Windows to replace my windows in the near future as well.
