Maybe you’ve picked up on a drop in temperature around your house. Energy bills rising. Or condensation building up on or inside your windows every morning.

Sound familiar? Your windows are telling you a signal.

Windows don’t last forever, and older ones shed theirs over time.

The gas between the panes leaks out, the rubber gaskets go rigid and contract, and what used to hold the cold out now barely slows it down.

In a place like St Leonards, where rain and wind can frequently feel more frequent than the sun, ageing windows make a noticeable difference to how warm and pleasant your house feels.

The Advanced Group is here to make things easier, with over 38 years of trusted experience. Whether you want new windows for a single room or a full house of replacement windows and doors, we’ll help you find the right fit and make sure everything is installed correctly.

Double Glazing for New Builds Scotland

When Your Windows Need Changing

Cracked glass? Rotten timber frames? Handles that don’t fasten properly? Some issues are easy to spot.

Other signs are harder to notice. By the time you see them, they’ve been losing you money for months or years.

how to stop condensation on windows

Condensation Between Glass Panes

If you can see moisture or fogging between the two panes of glass, this is a sure sign that the sealed unit has given way.

Once the seal fails, the argon gas that provides insulation escapes, and the window loses a large portion of its thermal performance.

Rising heating costs don’t have to drain your wallet. Restore your home’s thermal efficiency with perfectly sealed new windows.

draught proofing

Draughts and Cold Patches

Place your hand near the window edges on a windy day. Cold air coming through? The seals have worn away.

Draught proofing strips? They’re a quick fix. The problem only deteriorates as the rubber keeps perish.

Difficulty Opening or Closing

A window that catches, won’t close properly, or refuses to budge is not just an irritation. It’s a safety risk and an insulation issue. Warped frames, worn hinges, and failed mechanisms are the window’s way of saying it’s done.

Modern windows come with multi-point locking systems that are far ahead of the single-point catches on older models. Factor in toughened glass, and you’ve got seriously stronger protection.

Costly Energy Bills

Did you realise that windows are behind a considerable proportion of heat loss in any house? They’re the barrier between your home and the outside world.

Your old double glazing? It’s a thing of the past! The energy ratings are far below what’s on offer today, even if the original setup was solid back then.

New double glazed windows and doors will protect your house from high energy bills.

Advanced Group's range of double glazed windows in Showroom

Our Window Types in St Leonards

Every home in St Leonards is different. The right window choice depends on the building, the room, and how you occupy it.

The Advanced Group supplies and fits a full range of windows and doors in both double glazed and triple glazed options, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung styles.

casement bay window

Casement Windows

Casement windows are probably the UK’s most common window style! They’re side-hinged, open outwards, and are perfect for ventilation and simple to clean from inside.

Casement windows match just about any property style, whether it’s a modern home or a traditional property! They come in a huge range of colours and finishes, and the woodgrain effects replicate real timber without the maintenance or warping worries.

Sliding Sash 1

Sliding Sash Window Style

Our sliding sash windows look like original wooden sash frames. Modern thermal efficiency and safety are included as standard.

Proportions, sight lines, and opening mechanism all match the traditional style. Great for conservation areas or maintaining your property’s character.

Tilt and Turn Windows

About Tilt and Turn Windows

These windows give two options: tilting inward at the top for secure ventilation, and turning completely inward on a side hinge for easy cleaning.

They’re a well-liked choice for upper-floor flats where cleaning the outside of the glass from a ladder isn’t an option.

The tilt feature provides airflow without the security risks associated with a fully open window, which is particularly handy for families with young children.

Top Hung Windows

Top Hung Windows

Top hung windows are hinged at the top and open outward from the bottom, giving a smart choice for ventilation that also works to keep rain out.

Bathrooms, kitchens, stairwells, bay window setups, anywhere privacy and airflow both matter. That’s where top hung windows come into their own.

french-2

Full-Length French Windows

French windows are full-length windows that open outward much like French doors.

They work well in pairs and can be combined with sidelights to fill a wide opening with glass and natural light.

Scotland's Trusted uPVC Sash Window Specialists 

uPVC Double Glazing for St Leonards

The Advanced Group concentrates in uPVC frame materials for good reasons.

uPVC frame materials are especially well suited to the harsh Scottish climate, delivering durability and resistance to wild, windy, and wet weather. Unlike timber frames, uPVC won’t present the same warping or rot issues.

In addition, uPVC offers the benefit of being low maintenance.

Simply wipe it down with soapy water and it can look as good as new.

Quite possibly most importantly, our uPVC windows provide strong levels of energy performance. Constructed with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, working to restore energy efficiency in your home.

On top of all that, uPVC double glazing is also the most budget-friendly option out there.

This means you to often choose premium-grade glazing without blowing your budget. We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.

Save on Heating Bills in St Leonards

Let’s be straight, Scotland is cold, wet, and windy for a fair chunk of the year!

In that weather, the energy performance of your windows makes a genuine difference to how much you shell out on heating and how pleasant your property feels every day.

The thermal performance of a window is assessed by its U-value.

The lower the number, the less heat is lost through the 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 hit 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 difference is clearly shown on your energy costs.

Argon gas filled sealed units and low-E glass coatings perform the hard work in A-rated energy-efficient windows and doors. Heat gets pushed back in. Light still flows through.

If you’re moving from old single-glazed sash windows or early double glazing from the 1990s, you could see a noticeable drop in your heating spend within the first winter.

St Leonards has its share of double glazing businesses, and most supply entry-level products. Few, however, rival the calibre of the windows and doors fitted by The Advanced Group.

When Triple Glazing Is Worth It

Our experienced installers love chatting about triple glazing, and it’s a question that pops up a lot!

An extra pane of glass. Improved insulation. Better noise reduction. That’s triple glazing.

Exposed spot. Up a hill. Facing north. Near a busy road or under a flight path. If any of that sounds like your property, The Advanced Group is here to guide you through the benefits of triple glazing.
