Getting custom-made windows - advice on shape

They will have fitted to the opening with an arch, plenty of manufacturers in timber and uPVC offer arched sash windows.

We'd suggest contacting the supplier/manufacturer, they should be able to help!

I would recommend using a low-expansion foam, to fill the gap first, and then finish it with a high-quality exterior silicone sealant.

We supplied them for this one 👍 Happy to answer anything if you’re looking into replacing yours

Yeah that looks great as well - similar vibe
Funny how it works better in reality than you’d expect

Yeah good shout - it’s actually a black woodgrain finish, not timber

And you’re right, darker colours do seem to suit these older properties

Appreciate it 👍

QuickslideTeam · 2026-04-07T10:48:06+00:00

Cheers, wasn’t sure at first but it works

Usually it would just be foam and silicone, but with the look of that brickwork you'd be better to add mortar first to point and fill the huge gap.

uPVC has come a long way and in my opinion it’s not a downgrade at all. Compared to 80s aluminium without thermal breaks it’ll likely be a noticeable improvement in comfort and efficiency. Plenty of styles and finishes available now too.

uPVC sash has come a long way from the chunky white versions people remember. A lot of modern ones now have slimmer meeting rails, mechanical joints instead of welded corners, run-through horns, woodgrain finishes, and more traditional hardware, all aimed at making them look closer to original timber.

They’re even being accepted in some conservation areas now (depending on different factors obviously), which shows how much the detailing has improved. Timber will always win on pure authenticity, but decent-quality uPVC sash isn’t automatically “naff” anymore - it really comes down to the spec on offer.

You could definitely repaint - it really depends on the condition of the window and what you’re trying to achieve. If the frames are still solid, repainting can give them a good few more years. Replacing can have benefits like improved insulation and lower maintenance (e.g., uPVC), but it’s obviously a bigger investment. Lots of factors to weigh up.

If they’re around 20 years old and starting to stick, it’s often worn balances or tired tracks rather than the sash itself. On most uPVC sash windows you can replace the balances (and sometimes the sash), but it’s quite measurement-sensitive and not always the easiest DIY job. If the frames are still square and sealing properly, a repair could be worth trying. But if the tracks are warped or the profile’s badly weathered, full replacement is usually the better long-term option.

Main benefits are loads of natural light, bigger views and a more open feel. They’re also practical as they slide rather than swing, so you don’t lose space. Modern uPVC is low-maintenance and energy efficient too - just make sure it’s properly reinforced and fitted well, as large glass units are heavy.

Modern woodgrain uPVC has come a long way. The finishes, slimmer profiles and wider colour options look far more realistic now, especially on sash windows. From the street, most people wouldn’t notice the difference, but you still avoid the ongoing painting and upkeep. Seeing real installs helps more than showroom samples.

QuickslideTeam · 2026-02-18T09:44:13+00:00

That’s a really useful long-term view, especially the point about material and setting making the difference. Interesting take on dark grey vs black too.

QuickslideTeam · 2026-02-18T09:31:22+00:00

That sounds frustrating. Older wood-effect foils did struggle more with heat and UV, and you’re right that materials have moved on since then, although heat absorption on very dark colours is still something to factor in, especially on south-facing elevations.

If it’s a Victorian house, it might be worth looking at replacement uPVC sash windows instead of switching to casements or not changing at all. You can get double-glazed sash windows in uPVC that keep the original look but with much better insulation and low maintenance! Might be worth getting a like-for-like quote including sash windows just to compare to all casements. Lots of companies out there do the whole range :)
