We’ve installed thousands of windows over the last 34 years, take a look at what we have installed more recently.

New Windows Eaglesham
Quality Energy Efficient Double Glazed Windows & Doors




A drop in temperature inside the house. Increasing energy bills. Condensation forming on or inside the windows each morning. Ring any bells?
Does that ring true? Your windows are sending a signal they need replacing.
As windows age, they gradually lose their seal.
The gas between the panes gradually escapes, the rubber gaskets stiffen and contract, and what once blocked the cold out now hardly slows it down.
In Eaglesham, where the rain and wind can feel more common than sunshine, worn-out windows really impact how warm and cosy your house feels.
No need to worry about it! The Advanced Group has been doing this for over 38 years. Whether you want new windows for just one room or the whole house of replacement windows and doors, we’ll guide you to the right choice and get it all installed the right way.

Some issues are obvious. Cracked glass, rotten timber frames, handles that don’t close the way they should.
But other symptoms are less obvious, and by the time you notice them, they’ve probably already been losing you money for months, maybe even years.

Noticing moisture or fogging between your two sheets of glass tells you the sealed unit has given up.
Once the seal has gone, the argon gas that provides insulation leaks, and the window loses a significant portion of its thermal efficiency.
Increasing heating bills don’t have to keep eating into your pocket. Well sealed new windows will recover your home’s thermal efficiency and help push those costs back down.

Put your hand near the window edges on a windy day. Cold air getting through? The seals have gone.
Draught proofing strips give you time, but they’re a sticking plaster at most. The rubber continues to degrading, and the fault only gets worse.

Windows that jam, bind, or won’t close properly are a safety risk as well as an insulation problem. Warped frames, worn hinges, and failed mechanisms all point to the window has hit the end of its functional life.
Multi-point locking systems on modern windows are considerably more secure than the single-point catches on older frames, and options like toughened glass give extra protection.
Windows are responsible for a considerable proportion of heat loss in any property. They are the bridge between you and the outside elements.
Double glazing from years ago is a thing of the past, and the energy ratings will be significantly below what’s achievable today, even if the spec was decent when first fitted.
New double glazed windows and doors will guard your property from high energy bills.

Every Eaglesham home is different, and the right window choice depends on the house, the room, and how you use it.
A full lineup of windows and doors, double glazed and triple glazed, is ready from The Advanced Group, including uPVC casement, sash, tilt and turn, and top hung designs, all provided and installed by our team.

The most widely fitted window style in the UK. Side-hinged, opening outwards. Ideal for ventilation and simple to clean from inside.
Modern house or traditional house, casement windows work with the lot. A wide choice of colours and finishes is provided, and the woodgrain effects capture the look of timber without any of the maintenance or warping worries.

The sliding sash windows we install replicate the style of original wooden sash frames, while delivering modern thermal performance and security.
The proportions, sight lines, and opening mechanism mirror the traditional design. That’s essential if your property is in a conservation area or you just want to keep its charm.

These windows tilt inward at the top for safe ventilation and turn completely inward on a side hinge for easy cleaning.
For those living in upper-floor flats, tilt and turn windows are a wise choice, as cleaning the outside of the glass from a ladder isn’t feasible.
The tilt feature provides airflow without safety worries. Particularly useful for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, offering a sensible solution for ventilation that also helps to keep rain out.
You’ll often see them in bathrooms, kitchens, stairwells, and bay window configurations, rooms where both privacy and airflow count.

French windows are full-length panels that open outward, operating in the same way as French doors.
They’re great in pairs and can be matched with sidelights to fill a wide opening with glass and natural light.
The Advanced Group concentrates in uPVC frame materials for sound reasons.
Scottish weather is demanding, and uPVC is made to be long-lasting and resilient to wild, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot concerns.
Better still, uPVC is really low maintenance.
Just a quick wipe with soapy water and it looks good as new!
But more significantly, our uPVC windows are extremely energy effective. Built with multi-chambered uPVC, some of our frames can hit a U-value as low as 0.8 W/m2K, working to recover energy performance to your house.
And you want to hear the best part? uPVC double glazing is also the most cost-effective option available!
That means you can often choose higher-specification glazing without blowing the budget. We also provide glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
Cold, wet, and windy. That’s Scotland for a good portion of the year.
In that climate, the energy efficiency of your windows makes a noticeable difference to how much you pay on heating and how warm your house feels on a daily basis.
The thermal performance of a window is assessed by its U-value.
A lower figure means less heat being lost through the glass and frame. Right now, Scottish building regulations demand a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows attain a U-value of 1.2 W/m2K, while our premium range can reach values as low as 0.8 W/m2K, working at twice the standard of the regulatory minimum.
And where does that difference show up? Straight on your energy bills!
A-rated energy-efficient windows and doors use argon gas filled sealed units and low-E glass coatings to push heat back into the room, all while letting natural light through.
If you are switching from old single-glazed sash windows or early double glazing from the 1990s, you should see a real drop in your heating spend within the first winter.
While many double glazing companies in Eaglesham offer entry-level products, few can rival the standard of the windows and doors we provide.

Our skilled installers are often asked about our triple glazing options.
With an extra pane of glass, triple glazing offers improved insulation and greater noise dampening.
If your property is sitting in an exposed spot, up a hill, facing north, or near a busy road or under a flight path, give us a shout! The Advanced Group would be more than happy to talk you through the benefits of triple glazing.

We completely understand that new windows are an investment, and paying for them all at once isn’t always practical.
To help with this, we have available 0% APR and up to 4 years of interest free credit.
This allows you to install the windows you deserve while spreading the cost of your new windows and doors in a way that suits your finances.
