Windows That Suit Marylebone's Homes
Plenty of homes around Marylebone were built with generous bays and tall openings, and squeezing a standard white casement into them rarely does the house justice. We spend time at the survey getting the style, proportions and finish right, because a window you look at every day should be one you actually like.
Everything we fit is A-rated for energy efficiency, so the kerb appeal comes with warmer rooms and quieter evenings thrown in.
Sash, Bay and Casement Specialists
Modern uPVC sash windows give you the traditional sliding style with none of the rattling, sticking or repainting that comes with old timber. Bay window replacements are handled properly too, including new structural posts and jacks where the originals have sagged.
Prefer a cleaner look? Flush casements and slim-frame designs keep sight lines tidy on more modern homes. All styles come in white, anthracite grey, black and a range of woodgrain foils, with dual-colour frames available.

Our 10-Year Guarantee
Every window we fit in Marylebone is covered for 10 years, frames, sealed units and workmanship alike. With more than 25 years in the trade and over 750 5-star reviews, we intend to still be here answering the phone if you ever need us.
And because we never take deposits, you only ever pay for finished work.

Booking a Survey
Surveys are free, take under an hour and come with zero obligation. Paul measures every opening himself, talks through the options with samples in hand, and follows up with a written quote. From acceptance, made-to-order windows are typically fitted within a few weeks.

Frequently Asked Questions
Do you fit sash windows in Marylebone?
Yes, uPVC vertical sliding sash windows are one of our specialities. They keep the traditional look that suits many Marylebone homes while giving you A-rated double glazing, smooth balances and easy-clean tilt functions.
Can you replace a full bay window?
We can. Bay replacements are more involved than flat windows because the bay often carries structural load, so we fit proper support posts and jacks where needed. It is a job we do regularly and quote for accurately after seeing the bay.
What do new windows cost in Marylebone?
Prices vary with size, style and glass specification, and sash or bay windows sit above standard casements. We give a free written quote per house rather than guessing over the phone, and with no deposit you pay nothing until the work is done.
Will I need planning permission to change my windows?
For most houses, replacing windows is permitted development and needs no planning application. Rules differ if a property is listed or in a conservation area, and we will flag that at the survey if it applies to yours.
How disruptive is having a whole house of windows replaced?
We replace one opening at a time, so no room is ever left exposed. Carpets and furniture are sheeted, and a typical house takes one to two days. Most customers are surprised how quickly it is over.
Do you cover the streets between Marylebone and Swinley?
Yes, our patch covers the whole north side of Wigan including Marylebone, Swinley, Whitley and out towards New Springs. We are based in Atherton, so nowhere in the area is far away.
Can I mix window styles on one house?
Absolutely. Plenty of customers put sash windows on the front elevation and casements on the side and rear where nobody sees them, which keeps the cost down without spoiling the look of the house.
How energy efficient are your windows?
All our windows are A-rated as standard, with efficient double-glazed units, warm-edge spacer bars and multi-chambered frames. Compared with 20-year-old double glazing the difference in warmth and draught-proofing is significant.
Do new windows reduce outside noise?
Noticeably, yes. Modern sealed units with well-fitted frames cut a surprising amount of road and neighbourhood noise. If a room faces a busy road we can also spec acoustic glass for extra reduction.
Who actually fits the windows?
The same firm that quotes them. We supply and fit ourselves rather than passing your job to a subcontract crew, which is how the finish stays consistent and why the guarantee is straightforward, one company responsible for everything.
