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

New Windows Westhill
Quality Energy Efficient Double Glazed Windows & Doors




If you’ve spotted a temperature drop in your house, or spotted your energy bills rising, or condensation gathering on or inside your windows in the morning, it’s time taking notice.
Does that sound? Your windows are letting you know something’s.
Old windows shed their seal as the years pass.
That gas between the panes? It seeps away. The rubber gaskets stiffen and contract. And what used to keep the cold out hardly does the job.
Westhill’s rain and wind can feel more common than the sun. Ageing windows make a noticeable difference to how warm and cosy your property feels.
No need to stress about it! The Advanced Group has been doing this for over 38 years. Whether you need new windows for just one room or a full set of replacement windows and doors, we’ll guide you to the right choice and get it all installed properly.

Some faults are clear. Cracked glass, rotten timber frames, handles that don’t lock correctly.
Other signs, however, are less obvious, and by the time you spot, they could have been costing you money for months or even years.

Seeing moisture or fogging between your two sheets of glass indicates the sealed unit has failed.
The seal breaks. The argon gas leaks out. The window loses a large chunk of its thermal performance.
Rising heating bills don’t have to eat into your wallet. Bring back your home’s thermal performance with properly sealed new windows.

A windy day shows you everything. Place your hand near the edges of the window. Cold air sneaking through means the seals have deteriorated.
Draught proofing strips give a brief solution, but they’re just a sticking plaster on a issue that will only get worse as the rubber continues to perish.

Got windows that jam, won’t close right, or just refuse to budge? That’s a security risk and an insulation concern combined. Warped frames, worn hinges, and failed mechanisms all tell you the window has hit the end of its useful life.
Modern windows feature multi-point locking systems that are miles ahead of the single-point catches on older windows. Add toughened glass, and you’ve got significantly better safety.

Your windows are the cause of a large share of the heat loss in your house. They’re the barrier between you and the elements.
Double glazing from years ago is a thing of the past, and the energy ratings will be well below what’s available now, even if the spec was reasonable at the time.
Guard your property from high energy bills with new double glazed windows and doors.

No two Westhill houses are the same, and the ideal window choice depends on the building, the room, and how you live in it.
A full selection of windows and doors, double glazed and triple glazed, is on offer 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. Practical for ventilation and simple to clean from inside.
Casement windows suit most property kinds, from modern builds to traditional properties, and are provided in a wide selection of colours and finishes, including woodgrain effects that recreate the look of timber without the maintenance and risk of warping.
The classic look of wooden sash frames, recreated in every detail. That’s what our sliding sash windows provide, along with modern thermal performance and security.
Every proportion, sight line, and opening mechanism matches the traditional look. Whether your property sits in a conservation area or you simply want to keep its charm, these windows fit the bill.

Tilt them inward at the top for safe ventilation. Turn them fully inward on a side hinge for simple cleaning. Two modes, one window.
They’re especially popular in upper-floor flats, where climbing up a ladder to clean the outside of the glass is not realistic.
The tilt mode lets air in without the safety worries of having the window fully open, which is especially helpful if you’ve got young children.

Top hung windows are hinged at the top and open outward from the bottom, making them a practical choice for ventilation while helping to keep rain out.
They’re often installed in bathrooms, kitchens, stairwells, bay window setups, and other spaces where privacy and airflow are equally important.

Full-length windows that open outward like French doors. That’s exactly what French windows are.
Perfect in pairs. Match them with sidelights to fill a wide opening with glass and natural light.

We specialise in uPVC frame materials. And for good reason.
Scottish weather is unforgiving, and uPVC is built to be hardwearing and resilient to wild, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot concerns.
And there’s one more bonus: uPVC is really low maintenance!
Soapy water and a wipe. That’s all it needs to keep uPVC looking fresh.
More importantly though, our uPVC windows are seriously energy efficient. With multi-chambered uPVC engineering, some of our frames can hit a U-value as low as 0.8 W/m2K, helping to restore your home’s energy performance.
On top of all that, uPVC double glazing is also the most budget-friendly option on the market.
That means you can often upgrade to premium-grade glazing without blowing the budget! We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
Scotland is cold, wet, and windy for a good chunk of the year.
That climate means the energy rating of your windows makes a difference. It shapes how much you shell out on heating and how comfortable your house feels every single day.
The thermal efficiency of any window is measured by its 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 deliver a U-value of 1.2 W/m2K, while our premium range can achieve values as low as 0.8 W/m2K, operating at twice the standard of the regulatory minimum.
The difference shows on your energy costs.
A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat bounced back in, light still getting through.
If you’re coming from old single-glazed sash windows or early double glazing from the 1990s, you could see a really significant drop in your heating spend within just the first winter!
Westhill has a good number of double glazing businesses. Few come close to the calibre of our windows and doors.
Our trusted installers often get asked about our triple glazing range.
Triple glazing adds an extra pane of glass, which gives stronger insulation and significantly better noise reduction.
If your property is located in an exposed location, 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 guide you through the upsides of triple glazing.

We understand that new windows are an big purchase, and paying for them all at once isn’t always feasible.
That’s why we provide 0% APR and up to 4 years of interest free credit, which makes the process much less stressful!
It lets you get the windows you deserve and spread the cost of your new windows and doors in a way that suits perfectly for you!
