Why Sash and Case
Looks like 1890. Performs like today.
A modern sash and case window keeps the proportions, the astragal bars and the vertical slide that make a Scottish tenement look right, then quietly adds the sealing, the glazing and the balances that the original never had.
The rattle stopsModern brush seals and spiral balances kill the draught and the noise, while the sash still slides the way it always did.
Warm Where It Was Cold
Sealed double or slim double glazing in a period profile. The bay stops being the coldest seat in the room.
Slim double glazingQuieter Street
Sealed units and proper brush seals cut traffic noise dramatically compared with a single-glazed original.
Acoustic optionsNo More Repainting
Timber-effect finishes hold their colour without the scaffolding, the sanding and the two coats every few years.
Maintenance freeTilts In To Clean
Both sashes tilt inwards, so a top-floor flat can be cleaned safely from inside the room.
Tilt-in cleaningLocks That Work
Concealed multi-point locking on both sashes, rather than a single brass catch anyone can slip from outside.

FAQ
Sash Windows questions, answered.
The questions we hear most often from Scottish homeowners replacing sash windows. Pricing, conservation areas, heritage details and maintenance.
Not what you were after?
Speak to a real designer, no chatbot, no call-centre. We typically answer within an hour, 7 days a week.
Call 0800 029 3875How much do replacement sash windows cost?
A single heritage sash window typically costs between £750 and £1,400, fully installed including rip-out, disposal and certification. The final price depends on size, glazing bar configuration, foil colour, and whether structural remedial work is needed. Every Ultimate Home Solutions quote is free and without obligation.
Will heritage sash windows be accepted in a conservation area?
In most cases, yes. Our heritage sash profiles replicate the proportions, sash horns, bottom rails and glazing bars of traditional timber sash windows. We check your local conservation area requirements during the survey and, where consent is needed, can supply technical drawings and specifications for your planning application.
How do heritage uPVC sash windows compare to timber sash windows?
Visually, our heritage profiles are very close to timber originals. Performance-wise, they outperform timber on thermal efficiency, maintenance, and longevity. uPVC sash windows will not rot, warp, or need painting. They achieve A-rated thermal performance and last 25+ years. Timber sash windows require regular sanding, priming, and painting every 3 to 5 years.
Can you match the original proportions exactly?
Yes. Our surveyor measures every detail of your existing sash windows, including the meeting rail height, horn length, bottom rail depth, and astragal bar pattern. We then specify a heritage profile that replicates those proportions as closely as possible in uPVC.
How long does sash window installation take?
Most projects are completed in 1 to 3 working days depending on the number of windows. We give you a written day-by-day schedule before we start and your home is wind-and-watertight every evening.
Can I finance sash windows?
Yes. We offer Buy Now Pay 12 Months Later, flexible credit up to 24 months, and longer-term flexible credit up to 10 years. The initial eligibility check is a soft search with no impact on your credit score and gives an instant decision.
