Why sash windows

The timeless look, with none of the draughts

Sliding sash windows are one of the most recognisable features of Swindon's period homes — and with modern engineering, they no longer mean cold rooms or high heating bills.

Outstanding thermal performance

A++ rated glass and properly fitted frames keep the warmth in and the draughts out — homeowners see savings of up to £400 a year on heating.

Stay-Safe security, as standard

High-spec multi-point locks come fitted to every sash window we install, so the classic look never comes at the cost of peace of mind.

Built to last a lifetime

Sustainably sourced timber or premium uPVC, time-honoured craftsmanship with modern durability — easy to use and built to last.

Local knowledge, honest pricing

We know Swindon's diverse property types inside out — and give clear, transparent, no-fluff quotes with no nasty surprises.

Choose your material

Traditional timber, or maintenance-free uPVC

Both keep the authentic sliding sash look — the right choice comes down to upkeep, budget, and whether your property sits in a conservation area.

The classic sash profile, in a virtually maintenance-free frame. Ideal for homeowners who want the heritage look without the upkeep of timber.

Common questions

Sash windows: what homeowners ask us

Should I choose timber or uPVC sash windows?

It depends on your priorities. Timber gives the most authentic period look and is built with sustainably sourced wood and a traditional weights-and-pulleys system. uPVC gives you the same sliding sash profile with less ongoing maintenance. We'll talk you through both options for your specific property during your free quote.

Will new sash windows actually reduce my heating bills?

Yes — our sash windows are fitted with A++ rated glass and installed to the latest building regulations, which keeps the warmth in and the draughts out. Homeowners typically see savings of up to £400 a year on heating versus older, single-glazed sash windows.

Are your sash windows secure?

Every sash window we install comes with our Stay-Safe security approach, including high-spec multi-point locks fitted as standard — so you don't have to trade character for security.

How much does a sash window replacement cost?

Costs vary depending on size, material, and the number of windows. We provide free, no-obligation quotes that are clear and easy to understand, with no nasty surprises — get in touch below and we'll give you an honest figure for your home.
