Brilliant service, saved us a fortune
Sealed units arrived within the week and were a perfect fit. Saved a fortune compared to ripping out the whole window. Can't fault them at all – would definitely use again.
Our go-to supplier for trade
We've been using these guys for about two years now on all our renovation jobs. Consistent quality, decent prices, and they actually deliver when they say they will. The argon Low-E units are spot on.
Misted units sorted in a day
Our Victorian terrace had misted windows all over the house. They replaced all 12 sealed units in one day and didn't touch the original timber frames. Massive difference in warmth – wish we'd done it sooner.
Helpful team, got the sizes sorted
I measured up wrong initially (my own fault) and gave them the wrong dimensions. Rang up, spoke to a really helpful bloke who walked me through measuring properly. Replacement units arrived bang on size. Top marks.
Great value for landlords
I've got six flats and needed sealed units across most of them. The trade pricing was genuinely competitive and they handled the whole lot without any fuss. Already booked them for another property.
Good product, delivery slightly slow
The sealed units themselves are excellent quality – no complaints there at all. Delivery took a day longer than expected which was a bit annoying as I had a fitter booked. But the end result is great.
Bay window looks brand new
Had a large bay window with a blown unit that was driving me mad. They came out, measured up, and fitted the replacement sealed unit within the week. Looks like a brand new window. Absolutely chuffed.
Whole house done, really pleased
We had every window in the house done – 14 units in total. They quoted quickly, delivered on time, and the fitter was neat and professional. Noticeably warmer already and our energy bill has dropped.
Conservatory units replaced perfectly
The conservatory roof panels had all misted up and it looked awful. Got all the sealed units swapped out and it's like having a brand new conservatory. Really happy with the result and the price was reasonable.
Reliable supplier, been using them for years
As a trade installer I need a supplier I can rely on and these lot haven't let me down yet. Good communication, quality products, and they understand the trade side of things. Wouldn't go anywhere else now.
Argon fill made a huge difference
Went for the argon-filled Low-E units on the recommendation of their team and the difference is night and day. The front bedroom used to be freezing in winter – now it's the warmest room in the house. Worth every penny.
Good product, website could be easier
The actual double glazing unit is excellent and fits perfectly. Only reason for four stars is the website could be a bit easier to navigate when choosing options. But the product and service? No complaints.
Bathroom window sorted quickly
Had a misted bathroom window that had been bugging me for months. Rang up on Monday, unit was delivered Friday, and my local handyman fitted it in 20 minutes. Crystal clear again. Dead easy process.
Perfect for our period property
We needed slimline units for our Edwardian semi because the rebates are quite narrow. They recommended the right spec and the units fit perfectly into the original frames. The house looks exactly as it should – just much warmer.
Use them on every job now
I'm a builder and I've tried a few different sealed unit suppliers over the years. These are the ones I stick with. Fair trade prices, they don't mess you about on lead times, and the quality is consistently good.
No more condensation!
Our kitchen window always had condensation running down it every morning. Got the sealed unit replaced with a Low-E argon unit and it's completely gone. Should have done it ages ago. Quick and painless service too.
Quick turnaround, impressed
Ordered on a Tuesday, units arrived the following Monday. For bespoke sizes that's really quick. Fitted them myself – straightforward job. Glass quality is excellent and the seal looks solid. Very impressed overall.
Great product, tracking could be better
Units are really good quality and the price was fair. Had to chase up the delivery tracking a couple of times as it wasn't updating. Once they arrived though, perfect fit and they look great. Would still recommend.
Road noise practically gone
We live on a busy main road and the old single-pane windows were useless. Upgraded to their acoustic sealed units and the difference is unbelievable. Can finally have a proper night's sleep. Money well spent.
10 windows done, faultless
Had 10 sealed units replaced across the front and back of the house. Every single one was the correct size, delivered on the day they said, and fitted without any problems. Really professional outfit from start to finish.

For heritage properties requiring slimline units, krypton gas delivers excellent performance in narrower cavities. We also offer xenon gas for specialist commercial applications.
All our gas-filled units are manufactured to BS EN 1279-3 standards with a minimum 90% gas fill level, ensuring long-lasting thermal efficiency and compliance with Building Regulations Part L.
