Services Available

✅ CHANGE THE PANE, NOT THE FRAME

We specialise in removing “misty” broken-down glass sealed units and supplying and fitting new ones into most PVCu double glazed windows and doors. With the average cost of a brand new window being £680 – £850, it makes sense to just replace the glass unit (average cost being £130).
It really is a no-brainer!

✅ WINDOW UPGRADE

If your existing PVCu double glazed windows are in good condition, we can upgrade the energy proficiency of them by changing all the double glazed glass sealed units with our up-to-date A-rated quality glass sealed units, consisting of specially treated glass, warm edge technology spacer bars and Argon gas-filled cavities.

✅ HANDLE UPGRADE

Why not let us lift and improve the look of your existing PVCu double glazed windows with our range of new stunning lockable window handles? Choose a colour to suit your decor.


Colours available: Black, Chrome, Gold, Satin Chrome, and obviously White.

✅ INTERNAL PVCu TRIM RENEWAL

Sometimes the trims around the inside of your existing windows can be dirty, discoloured, covered in old paint, or even loose and draughty. We can remove the old trims and then supply and re-trim using our range of PVCu trims. This will definitely lift and enhance the look of your windows, especially when re-vamping or decorating your rooms.

✅ ADDED SECURITY AND OPENING RESTRICTION

We can supply and fit our cable window restrictors to most PVCu opening windows.
They are made to British standards, are key lockable, and restrict how far a window can be opened out for added security.

Available in the following colours: White, Black, Brown, and Gold.

✅ ADDED SECURITY TO PVCu DOORS

When you move into your new home, it is always advisable to change the locks on the doors. We have a full range of Euro Cylinder (barrel) locks which we can supply and fit to most PVCu doors.
We can also fit our Sash Jammers to inward-opening back doors for more improved security.

What are Misty or Broken Units?

When the seal between the two panes of glass fails, windows become “misty” from moisture and condensation inside the unit.

Not only does it look unsightly, but the window no longer performs 100% thermally. This is obviously the same with broken units.

If your PVC windows are in good condition and you do not want the expense, hassle, or mess of having your whole window(s) replaced, we can replace your glass sealed units with up-to-date A-rated quality new ones, which consist of specially coated glass, warm edge technology spacer bars, and Argon gas-filled cavities. Most glass sealed units can be replaced in existing frames.

Freshen and Modernise your Existing Windows

If you would like to freshen up the look of your existing windows, an easy and affordable way is for us to simply change your handles.
They come in a range of colours and are all lockable.
Colours available are:

  • White

  • Silver/Chrome

  • Gold

  • Brushed Silver/Chrome

  • Brushed Gold

  • Black

Another way of freshening up your existing windows is by us re-trimming the inside of them.Old trims are often discoloured, dirty, covered in old paint, loose, or draughty.Re-trimming is affordable, clean, and fresh—also helping the window be draught-free.

Security and Safety

As discussed previously, our range of new handles are all lockable.
So if your existing ones aren’t, or you have lost the keys, let us replace them.

Our range of cable restrictors serve two purposes:

  • They are great on lower-floor windows, as they restrict the opening to help prevent unwanted guests.

  • On upper-floor windows, they are great for preventing children, animals, or other items from falling out.

When it comes to doors, our range of Sash Jammers—both lockable and unlockable—are great as extra locks, giving you extra peace of mind during the day and especially at night.

Also, we have a full range of barrel locks for PVCu doors (you really should change them, especially when you move into a new home).

Frequently Asked Questions

Do I need to replace my entire window if the glass is misty?

No, not at all! If the frame is still in good condition, we can simply replace the glass sealed unit. It’s far more affordable and causes much less disruption than a full replacement.

How much does it cost to replace a misted or broken glass unit?

On average, a replacement glass sealed unit costs around £130—compared to £680–£850 for a brand new window. It’s a cost-effective solution that makes a big difference.

Can you improve the energy efficiency of my existing windows?

Yes! We can upgrade your current glass units to A-rated energy-efficient sealed units using modern materials like warm edge spacers, argon gas, and coated glass.

Are your window handles lockable?

Yes, all our replacement handles are lockable and available in a range of colours including white, black, chrome, satin chrome, and gold.

Do you offer added security features for windows and doors?

Yes. We install cable restrictors for windows and sash jammers and new barrel locks for doors, adding extra security and peace of mind.

Can you fix draughty or discoloured trims?

Absolutely. We offer internal PVCu trim renewal, removing old trims and replacing them with clean, fresh ones—improving both appearance and insulation.

Do you work on all types of double glazed windows and doors?

We work on most PVCu double glazed windows and doors. If you’re unsure, we’re happy to take a look and give advice during a free survey.

Is there a charge for a quote or survey?

No, we offer a free, no-obligation survey and quote so you can make an informed decision without pressure.

How long does it take to get the new glass units fitted?

We’ll contact you to arrange a fitting—usually within a week or two.

Are you insured and experienced?

Yes, we are fully insured and have over 43 years of experience in the double glazing industry. We’re a local, family-run business you can trust.
