Scotland's Trusted uPVC Sash Window Specialists 

You’ve felt the temperature shifting in your home. Energy bills are rising. Condensation sits on or inside your windows every morning.

If that seems familiar, your windows are sending you a signal.

Over time, older windows start to lose their seal.

That gas between the panes? It leaks out. The rubber gaskets harden and contract. And what used to keep the cold out hardly holds up.

Living in Garthdee, you know that rain and wind can outweigh the sunny days, and ageing windows make a noticeable difference to how warm and comfortable your home feels.

No need to worry about it! The Advanced Group has been helping homeowners 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 option and get it all fitted properly.

How to Tell Your Windows Need Replacing

Cracked glass? Rotten timber frames? Handles that don’t close right? Some problems are pretty obvious.

Other signs, however, are easier to miss, and by the time you notice, they might have been costing you money for months or even years.

how to stop condensation on windows

Condensation Trapped Between the Panes

Moisture or fogging between the two sheets of glass is a tell-tale sign. The sealed unit has given up.

The seal goes. The argon gas seeps out. The window loses a significant chunk of its thermal performance.

Don’t pour money away with rising heating prices and make sure to restore your home’s thermal efficiency with properly sealed new windows.

draught proofing

Draughts and Cold Patches

Try a quick test: hold your hand near the edges of the window on a windy day. If cold air is sneaking through, the seals have broken down.

Sure, draught proofing strips can do something for a short time, but they’re honestly a sticking plaster. The problem only worsens as the rubber continues to breaking down.

Difficulty Opening Your Windows

If your windows stick, won’t lock correctly, or are tough to open, this presents both a safety risk and an insulation concern. Warped frames, worn hinges, and failed mechanisms are all signals that the window has reached the end of its functional life.

Multi-point locking systems far exceed the old single-point catches for safety. Toughened glass provides extra safety.

Window Replacement

Climbing Energy Bills

A significant proportion of heat loss in any property happens through the windows. They represent the boundary between your indoor space and the outside world.

If your double glazing is dated, the energy ratings will very likely be far below what’s available now, even if they were a reasonable specification when first fitted.

Want to guard your property from those high energy bills? New double glazed windows and doors are the answer.

Popular Window Styles in Garthdee

Every Garthdee house is different, and the right window style depends on the building, the room, and how you live in it.

The Advanced Group supplies and installs a wide choice of windows and doors in double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung designs.

Sash windows vs Casement Windows

Classic Casement Windows

Perhaps the most popular window choice in the UK, casement windows are side-hinged and open outwards, which makes them great for ventilation and straightforward to clean from inside.

Casement windows complement just about every property kind, whether it’s a modern build or a traditional house! They are offered in a wide selection of colours and finishes, and the woodgrain effects look just like real timber without the maintenance or warping risk.

Sash Windows Brochure

About Sliding Sash Windows

The classic look of wooden sash frames, replicated in every detail. That’s what our sliding sash windows provide, along with modern thermal performance and protection.

Proportions, sight lines, and opening mechanism all mirror the traditional design. Perfect for conservation areas or maintaining your property’s personality.

tilt and turn windows dundee

uPVC Tilt and Turn Windows

Tilt inward at the top for secure ventilation. 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 an option.

The tilt feature lets air in without the safety risks of having the window fully open, which is especially useful if you’ve got young children.

after-top-hung

About Top Hung Windows

Top hung windows hinge at the top and open outward from the bottom. This makes them a sensible choice for ventilation while helping to keep rain from getting in.

Bathrooms, kitchens, stairwells, bay window configurations, anywhere privacy and airflow both matter. That’s where top hung windows work best.

Double Glazed French Windows

Full-Length French Windows

Full-length windows that open outward like French doors. That’s what French windows deliver.

Pair them up and match them with sidelights, and you can open up a wide opening with glass and natural light. The effect is striking.

How to Clean & Maintain UPVC Windows

uPVC Window Double Glazing in Garthdee

We focus in uPVC frame materials. And for sound reason.

uPVC frame materials are particularly well suited to the harsh Scottish climate, providing hardwearing performance and resilience to rough, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot problems.

Not only that, but uPVC is low maintenance.

Just a quick wipe with soapy water and it looks good as new!

Energy performance is where our uPVC windows truly deliver. Multi-chambered uPVC construction, U-values as low as 0.8 W/m2K on some frames, and a proper boost to the energy performance of your property.

And best of all? uPVC double glazing is also the most affordable option.

This means you to often fit higher-specification glazing without exceeding your budget. We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.

Choosing replacement windows

Your Garthdee Home’s Energy Efficiency

Scotland delivers cold, wet, and windy weather for a good chunk of the year.

In that type of climate, the energy efficiency of your windows truly influences how much you spend on heating and how warm your house feels day to day.

The thermal performance of any window is measured by its U-value.

A lower U-value translates to less heat being lost through the glass and frame. Scottish building regulations currently set a maximum U-value of 1.6 W/m2K for replacement windows.

Our standard double glazed windows come in at 1.2 W/m2K, and the premium models can reach 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 appears on your energy bills.

A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat bounced back in, light still coming through.

Upgrading from old single-glazed sash windows or 1990s double glazing? You could see a clear drop in heating bills within the first winter.

While many double glazing businesses in Garthdee provide standard products, few can match the calibre of the windows and doors we install.

Triple Glazing {LocationsAB(location)}

When Triple Glazing Is Worth It

Our trusted installers are regularly asked about the triple glazing range we carry.

Triple glazing adds an extra pane of glass, which delivers improved insulation and noticeably improved noise control.

Exposed location. Up a hill. Facing north. Near a busy road or under a flight path. If any of those sounds like your property, The Advanced Group is on hand to talk you through the advantages of triple glazing.
