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

New Windows Sandfordhill
Quality Energy Efficient Double Glazed Windows & Doors




A drop in temperature throughout the house. Increasing heating costs. Condensation forming on or inside the windows come morning. Ring any bells?
If any of that rings familiar, your windows are telling you something.
The seal on older windows deteriorates over time.
The gas between the panes leaks out, the rubber gaskets stiffen and pull away, and what used to keep the cold out now barely makes a difference.
Living in Sandfordhill, you know that rain and wind can beat the sunny days, and worn-out windows make a proper difference to how warm and cosy your house feels.
Over 38 years in the trade, and The Advanced Group is still here, available to help. Whether it’s one room or the full house that requires new windows and doors, we’ll find the right solution and have everything fitted the right way.

Some signs are easy to spot, like cracked glass, rotten timber frames, and handles that won’t lock the right way.
But then there are the subtle signs. The ones you miss until they’ve already been costing you money for months, possibly years.

If you can see moisture or fogging between the two panes of glass, this is a sure sign that the sealed unit has failed.
The seal breaks, and with it escapes the argon gas that delivered the insulation. The window loses a large chunk of its thermal performance.
Don’t let climbing heating costs chip away at your budget. Restore your home’s thermal performance by choosing perfectly sealed new windows.

A windy day shows you everything. Place your hand near the edges of the window. Cold air getting through means the seals have gone.
Draught proofing strips can help temporarily, but they’re really a sticking plaster on a fault that’ll only worsen as the rubber keeps degrading.

Jamming windows that won’t close right aren’t just inconvenient, they’re a security risk and an insulation problem too. Warped frames, worn hinges, and failed mechanisms all signal a window that’s hit the end of its useful 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 provide further security.

Your windows are how a large amount of your home’s heat is lost. That thin bridge between you and the outside weather counts more than most people think.
If your double glazing is ageing, the energy ratings will almost always be significantly below what’s achievable today, even if they were a decent specification when originally fitted.
Fitting new double glazed windows and doors is one of the best ways to protect your house from high energy bills.

No two Sandfordhill homes are the alike, and the best window choice hinges on the building, the room, and how you live in it.
The Advanced Group supplies and fits a full choice of windows and doors in both double glazed and triple glazed configurations, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung types.

The most common window type in the UK. Side-hinged, opening outwards. Ideal for ventilation and easy to clean from inside.
Casement windows complement just about any property style, whether it’s a modern home or a traditional property! They are offered in a big selection of colours and finishes, and the woodgrain effects replicate real timber without the maintenance or warping risk.
The traditional look of wooden sash frames, recreated in every detail. That’s what our sliding sash windows offer, along with modern thermal efficiency and security.
Every proportion, sight line, and opening mechanism matches the traditional look. Whether your property is in a conservation area or you simply want to hold onto its character, these windows do the job.

These windows tilt inward at the top for protected ventilation and turn completely inward on a side hinge for effortless cleaning.
They’re particularly well-liked in upper-floor flats, where climbing up a ladder to clean the outside of the glass isn’t feasible.
The tilt mode lets air in without the security risks of having the window wide open, which is especially useful if you’ve got young children.

Hinged at the top, opening outward from the bottom. Smart for ventilation and great at keeping rain out.
You’ll often spot them in bathrooms, kitchens, stairwells, and bay window arrangements, places where both privacy and airflow are important.

Full-length windows that open outward like French doors. That’s exactly what French windows deliver.
In pairs, they work fantastic, and you can combine them with sidelights to open up a wide opening with glass and lots of natural light.

uPVC frame materials. That’s what The Advanced Group focuses in, and the reasons are sound.
Scottish weather is harsh. uPVC is designed to take it. Durable, resilient to wild, windy, wet conditions. No warping or rot concerns like timber.
uPVC is low maintenance too.
Soapy water and a quick wipe down. That’s all it needs to keep uPVC looking good as new.
But more significantly, our uPVC windows are highly energy performant. Engineered with multi-chambered uPVC, some of our frames can hit a U-value as low as 0.8 W/m2K, helping restore energy performance to your house.
On top of all that, uPVC double glazing is also the most budget-friendly option on the market.
That allows you can often go for premium-grade glazing without breaking the budget. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Scotland is cold, wet, and windy for a large chunk of the year.
In that environment, the energy efficiency of your windows makes a real difference to how much you pay on heating and how warm your home feels every day.
The thermal efficiency of a window is measured by its U-value.
The lower that number goes, the less heat gets through. Scottish building regulations set the maximum at 1.6 W/m2K for replacement windows at present.
Our standard double glazed windows deliver 1.2 W/m2K, and our premium options can hit 0.8 W/m2K! That’s performance at twice the regulatory minimum!
The evidence? It appears on your energy bills.
A-rated energy-efficient windows and doors feature argon gas filled sealed units and low-E glass coatings to bounce heat back into the room, all while letting natural light through.
If you’re moving from old single-glazed sash windows or early double glazing from the 1990s, you could see a significant drop in your heating bills within the first winter.
While many double glazing companies in Sandfordhill offer standard products, few can rival the calibre of the windows and doors we provide.
Triple glazing is one of the most regular enquiries our trusted installers get.
Triple glazing has an extra pane of glass, helping it to provide improved insulation and improved noise levels.
Exposed area. Up a hill. Facing north. Near a busy road or under a flight path. If any of that rings true like your property, The Advanced Group is here to walk you through the benefits of triple glazing.

New windows are an investment, and we understand that paying for them all at once isn’t always possible.

It means you get the windows you want and spread the cost of your new windows and doors in a way that works nicely for you!
