Fitting Scotland Perfectly
New Windows Prestonpans
Quality Energy Efficient Double Glazed Windows & Doors




You’ve spotted the temperature changing in your home. Bills are up. Condensation gathers on or inside your windows each morning.
That nagging feeling? It’s your windows signalling to you they need attention.
Over time, older windows gradually lose their seal.
Between the panes, the gas seeps away. The rubber gaskets stiffen and shrink. What once blocked the chill now hardly registers.
In a location like Prestonpans, where rain and wind are sometimes more regular than sunshine, worn windows have a noticeable impact on how warm and cosy your home feels.
However not to worry, The Advanced Group is here to assist with over 38 years of trusted service. Whether you need new windows for a single room or a full house of replacement windows and doors, we can guide you to the right option and get everything fitted correctly.

Some faults are obvious. Cracked glass, rotten timber frames, handles that don’t fasten correctly.
Other signs, though, are harder to spot, and by the time you notice, they might have been losing you money for months or even years.

Can you notice moisture or fogging trapped between the two sheets of glass? That tells you the sealed unit has broken down.
Once the seal breaks, the argon gas that gives insulation escapes, and the window loses a large chunk of its thermal performance.
Rising heating prices don’t have to drain your wallet. Restore your home’s thermal efficiency with perfectly sealed new windows.

Put your hand near the window edges on a windy day. Cold air sneaking through? The seals have gone.
Draught proofing strips? They’re a quick fix. The issue only worsens as the rubber keeps perish.

Got windows that jam, won’t fasten right, or just refuse to cooperate? That’s a safety risk and an insulation issue rolled into one. Warped frames, worn hinges, and failed mechanisms all show you the window has reached the end of its working life.
Multi-point locking systems on today’s windows deliver significantly greater protection than the single-point catches used in older windows, and toughened glass options give an additional layer of security.

A considerable amount of heat loss in any home occurs through the windows. They represent the bridge between your internal space and the outside weather.
Your old double glazing? It’s a thing of the past! The energy ratings are far below what’s available now, even if the original setup was solid when first installed.
Want to protect your home from those high energy bills? New double glazed windows and doors are the solution.

Every property in Prestonpans is different. The right window type 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 specifications, including uPVC casement, sash, tilt and turn, and top hung styles.
The casement window takes the crown of the UK’s most popular type. Side-hinged and opening outwards, they’re ideal for ventilation and a doddle to clean from inside.
Suitable for most property kinds, from modern houses to traditional properties, casement windows are offered in a wide choice of colours and finishes, including woodgrain effects that mimic the appearance of timber without the maintenance or fear of warping.

Our sliding sash windows recreate the look of original wooden sash frames while providing modern thermal performance and protection.
The proportions, sight lines, and opening mechanism match the traditional design. That’s essential if your property is in a conservation area or you just want to maintain its character.
Tilt them inward at the top for secure ventilation. Turn them fully inward on a side hinge for easy cleaning. Two modes, one window.
For residents in upper-floor flats, tilt and turn windows are a practical choice, as cleaning the outside of the glass from a ladder isn’t practical.
The tilt function is a real bonus! You get airflow without the safety risks of a fully open window, which is especially useful if you’ve got young children at home.
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.
They’re often installed in bathrooms, kitchens, stairwells, bay window setups, and other spaces where privacy and airflow are equally valued.

Think of them as full-length windows that open outward, exactly like French doors. That’s French windows for you.
Perfect in pairs. Match them with sidelights to open up a wide opening with glass and natural light.

The Advanced Group’s specialism is uPVC frame materials, and this decision is backed by solid reasons.
Scottish weather dishes out everything at your windows. uPVC is designed to handle it, durable, resilient to harsh, windy, wet weather, and without the warping or rot worries that plague timber frames.
And here’s one more bonus: uPVC is seriously low maintenance!
Simply wipe it down with soapy water and it can look fresh.
Energy performance is where our uPVC windows really deliver. Multi-chambered uPVC construction, U-values as low as 0.8 W/m2K on some frames, and a genuine boost to the energy performance of your house.
Better of all? uPVC double glazing is the most budget-friendly option.
This means you to often choose higher-specification glazing without breaking your budget. We also provide glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.

Scotland is cold, wet, and windy for a good chunk of the year.
With that environment, your windows’ energy efficiency directly impacts your heating costs and how cosy your property feels daily.
U-value. That’s the measurement that tells you how thermally efficient a window truly is.
The lower that number, the less heat gets out through your glass and frame. Scottish building regulations currently require a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows reach 1.2 W/m2K, and our premium products can achieve values as low as 0.8 W/m2K. That’s high-quality double glazing and triple glazing that works twice as well as the regulatory minimum.
That improvement is clearly shown on your energy bills.
A-rated energy-efficient windows and doors come with argon gas filled sealed units and low-E glass coatings to push heat back into the room, all while allowing natural light through.
If you’re coming from old single-glazed sash windows or early double glazing from the 1990s, you could see a properly clear drop in your heating bills within just the first winter!
Plenty of double glazing companies in Prestonpans sell standard products, but not many can compete with the calibre of the windows and doors we fit.

Triple glazing is one of the most common enquiries our trusted installers receive.
With an extra pane of glass, triple glazing provides stronger insulation and greater noise dampening.
If your property is located in an exposed area, up a hill or high above sea level, facing north, or near a busy road or under a flight path, The Advanced Group would be more than pleased to guide you through the benefits of triple glazing.

We recognise that new windows are a notable spend, and paying for them in full all at once isn’t always possible.
That’s exactly why we provide 0% APR and up to 4 years of interest free credit.
It means you can get the windows you need through helping you spread the cost of your new windows and doors in a way that suits for you.
