We’ve installed thousands of windows over the last 34 years, take a look at what we have installed more recently.
Fitting Scotland Perfectly
New Windows Eccles
Quality Energy Efficient Double Glazed Windows & Doors




A shift in temperature throughout the house. Rising energy bills. Condensation sitting on or inside the windows each morning. Ring any bells?
That familiar feeling? It’s your windows letting you something.
As windows age, they start to lose their seal.
The gas between the panes escapes, the rubber gaskets stiffen and contract, and what used to keep the cold out now barely makes a difference.
Living in Eccles, you get that rain and wind often outnumber the sunny days, and tired windows make a proper difference to how warm and cosy your home feels.
Over 38 years in the industry, and The Advanced Group is still here, available to lend a hand. Whether it’s one room or the full house that requires new windows and doors, we’ll find the right fit and have everything fitted just right.

The obvious ones stand out. Cracked glass, rotten timber frames, handles that refuse to lock the way they should.
Other symptoms, however, are harder to spot, and by the time you spot, they may have been costing you money for months or even years.

Seeing moisture or fogging between your two sheets of glass means the sealed unit has broken down.
The seal breaks. The argon gas seeps out. The window loses a significant amount of its thermal efficiency.
Why waste money away on rising heating costs? Recover your home’s thermal efficiency with perfectly sealed new windows instead.

A windy day shows you a lot. Put your hand near the edges of the window. Cold air sneaking through tells you the seals have worn away.
Draught proofing strips can help temporarily, but they’re really a sticking plaster on a fault that’ll only get worse as the rubber continues to degrading.

Windows that jam, won’t close properly, or refuse to open are both a safety risk and an insulation concern. Warped frames, worn hinges, failed mechanisms. The window has reached the end of its functional life.
The single-point catches on older windows don’t compete with the multi-point locking systems on modern windows. Factor in toughened glass, and your home gains a proper security upgrade.

Did you realise that windows are behind a large amount of heat loss in any home? They’re the link between your house and the outside elements.
Double glazing from the past is just that, in the past. The energy ratings sit significantly below modern standards, even if the original spec was reasonable back then.
High energy bills don’t have to be the norm. New double glazed windows and doors work to shield your property and pull those costs down.

Every Eccles house is different, and the right window choice depends on the building, the room, and how you use it.
The Advanced Group offers a full selection of windows and doors in both double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung types.
The casement window claims the crown of the UK’s most common style. Side-hinged and opening outwards, they’re practical for ventilation and a doddle to clean from inside.
Suitable for most property styles, from modern builds to traditional properties, casement windows are available in a wide selection of colours and finishes, including woodgrain effects that recreate the look of timber without the maintenance or risk of warping.

The sliding sash windows we install mirror the appearance of original wooden sash frames, while offering modern thermal performance and protection.
Every proportion, sight line, and opening mechanism matches the traditional design. Whether your property is in a conservation area or you simply want to keep its personality, these windows do the job.
These windows offer two functions: tilting inward at the top for protected ventilation, and turning fully inward on a side hinge for simple cleaning.
They’re particularly popular in upper-floor flats, where getting up a ladder to clean the outside of the glass isn’t an option.
The tilt mode enables airflow without the security concerns that come with a fully open window, which is especially useful for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, making them a smart choice for ventilation while working to keep rain out.
They are often fitted in bathrooms, kitchens, stairwells, bay window setups, and other spaces where privacy and airflow are both valued.

French windows are full-length windows that open outward just like French doors.
Ideal in pairs. Combine them with sidelights to flood a wide opening with glass and natural light.

The Advanced Group’s speciality is uPVC frame materials, and this decision is supported by good reasons.
Scottish weather can be brutal, but uPVC handles it all! It’s durable, resists wind, rain, and the roughest of it, and you won’t get the warping or rot problems that timber frames come with.
Beyond that, uPVC delivers the benefit of being low maintenance.
Soapy water and a wipe. That’s all it needs to get uPVC looking good as new.
Here’s the genuinely big part: our uPVC windows are highly energy efficient! Designed with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, which seriously works to boost your home’s energy efficiency.
On top of all that, uPVC double glazing is also the most budget-friendly option out there.
Higher-spec glazing without exceeding the budget? That’s what uPVC offers. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.

Scotland’s weather is cold, wet, and windy for a large portion of the year.
With that weather, your windows’ energy rating genuinely impacts your heating costs and how cosy your house feels daily.
Thermal efficiency is measured by U-value.
The lower the value, the less heat gets out through the glass and frame. Scottish building regulations currently demand a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows perform at 1.2 W/m2K, and the premium range can achieve as low as 0.8 W/m2K. That’s double glazing and triple glazing working at twice the level of the regulatory minimum.
The difference is reflected on your energy bills.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are amazing at bouncing heat back into the room while still letting loads of light through.
If you’re upgrading from old single-glazed sash windows or early double glazing from the 1990s, you could see a real drop in your heating spend within the first winter.
Eccles has its share of double glazing firms, and most offer entry-level products. Few, however, come close to the quality of the windows and doors provided by The Advanced Group.

We get asked about triple glazing a lot.
With an extra pane of glass, triple glazing provides stronger insulation and better noise dampening.
Exposed location. Up a hill. Facing north. Near a busy road or under a flight path. If any of that fits like your property, The Advanced Group is on hand to guide you through the benefits of triple glazing.

New windows are an significant spend. Paying for them all at once? Not always practical. We know that.
That’s why we provide 0% APR and up to 4 years of interest free credit, making the purchase much easier!
This helps you get the windows you want by spreading the cost of your new windows and doors in a way that fits for you.
