Scotland's Trusted uPVC Sash Window Specialists 

Perhaps you’ve picked up on a change in temperature in your house. Heating bills rising. Or condensation forming on or inside your windows in the morning.

If that matches your situation, your windows are sending you a clear signal.

Windows don’t keep their seal indefinitely, and older ones lose theirs over time.

That gas between the panes? It escapes. The rubber gaskets harden and shrink. And what once kept keep the cold out barely slows it down.

Longhill’s rain and wind can feel more frequent than the sun. Worn windows make a clear difference to how warm and cosy your house feels.

No need to stress about it! The Advanced Group has been helping homeowners for over 38 years. Whether you need new windows for just one room or a full set of replacement windows and doors, we’ll match you with the right choice and get it all fitted the right way.

Key Signs Your Windows Need Replacing

Some faults are obvious. Cracked glass, rotten timber frames, handles that don’t close properly.

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

how to stop condensation on windows

Condensation Forming Between the Panes

Can you spot moisture or fogging sitting between the two sheets of glass? That means the sealed unit has given way.

Once the seal goes, the argon gas that provides insulation leaks out, and the window loses a significant amount of its thermal performance.

Don’t waste money away with rising heating costs and make sure to recover your home’s thermal efficiency with properly sealed new windows.

draught proofing

Cold Spots and Draughts

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

Draught proofing strips can help for a while, but they’re a sticking plaster on a fault that will only get worse as the rubber keeps on degrade.

Windows That Stick

Got windows that jam, won’t close right, or just refuse to cooperate? That’s a security risk and an insulation concern rolled into one. Warped frames, worn hinges, and failed mechanisms all tell you the window has come to the end of its useful life.

The single-point catches on older windows can’t compete with the multi-point locking systems on modern frames. Throw in toughened glass, and your property has a serious safety upgrade.

Window Replacement

Are Your Energy Bills Too High?

Windows account for a significant amount of heat loss in any home. Your window is the boundary between you and the outside elements.

Old double glazing doesn’t compete. The energy ratings are far below what’s available now, even if the original specification was decent at the time.

High energy costs don’t have to be the default. New double glazed windows and doors work to shield your home and bring those bills down.

Types of Windows We Fit in Longhill

Every Longhill property has its own feel. The right window choice depends on the house, the room, and how you use it.

We stock and install a full choice of double glazed and triple glazed windows and doors, including uPVC casement, sash, tilt and turn, and top hung styles.

Sash windows vs Casement Windows

Classic Casement Windows

Casement windows could well be the UK’s most widely chosen window type! They’re side-hinged, open outwards, and are great for ventilation and simple to clean from inside.

Casement windows go with most property styles. Modern houses, traditional properties, everything in between. Available in a wide choice of colours and finishes, including woodgrain effects that replicate the look of timber without the maintenance or warping worry.

Sash Windows Brochure

About Sliding Sash Windows

Like the look of original wooden sash frames? Our sliding sash windows recreate that original appearance while packing in modern thermal performance and safety.

The proportions, sight lines, and opening mechanism all match the traditional design, which is great if your property’s in a conservation area or you just want to maintain its personality.

tilt and turn windows dundee

Practical Tilt and Turn Windows

Tilt inward at the top for protected ventilation. Turn completely inward on a side hinge for easy cleaning.

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

The tilt mode provides airflow without the safety worries that come with a fully open window, which is especially helpful for families with young children.

after-top-hung

About Top Hung Windows

Hinged at the top, opening outward from the bottom. Practical for ventilation and good at keeping rain out.

They are commonly used in bathrooms, kitchens, stairwells, bay window configurations, and other spaces where privacy and airflow are both needed.

Double Glazed French Windows

About French Windows

French windows work just like French doors but are full-length windows that open outward.

Pair them up and combine them with sidelights, and you can fill a wide opening with glass and natural light. The effect is beautiful.

How to Clean & Maintain UPVC Windows

Longhill uPVC Double Glazing

The Advanced Group focuses in uPVC frame materials for sound reasons.

Scottish weather is brutal. uPVC is built to handle it. Long-lasting, tough to wild, windy, wet conditions. No warping or rot issues like timber.

Not only that, but uPVC is low maintenance.

Just a simple wipe with soapy water and it can look good as new!

More significantly however, our uPVC windows are seriously energy effective. With multi-chambered uPVC engineering, some of our frames can achieve a U-value as low as 0.8 W/m2K, helping to bring back your home’s energy efficiency.

And you want to hear the best part? uPVC double glazing is also the most affordable option available!

That allows you can often opt for premium-grade glazing without stretching the budget. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.

Choosing replacement windows

Energy Efficiency and Heating Bills in Longhill

Scotland’s weather is cold, wet, and windy for a large chunk of the year.

With that weather, your windows’ energy performance directly impacts your heating bills and how warm your house feels daily.

U-value. That’s the figure that shows you how effective a window really is.

Lower value, less heat lost. Scottish building regulations currently demand a maximum of 1.6 W/m2K for replacement windows.

Our standard double glazed windows come in at 1.2 W/m2K, and the premium options can get down to as low as 0.8 W/m2K. That’s double glazing and triple glazing performing at twice the level of the regulatory minimum.

The difference shows on your energy costs.

A-rated energy-efficient windows and doors feature argon gas filled sealed units and low-E glass coatings to push heat back into the room, all while letting natural light through.

Old single-glazed sash windows or 1990s double glazing? Upgrade them, and you could see a clear drop in heating spend before the first winter is out.

While many double glazing companies in Longhill supply entry-level products, few can compare with the standard of the windows and doors we install.

Triple Glazing {LocationsAB(location)}

Triple Glazing: When to Choose It

We get asked about triple glazing a lot.

Triple glazing has an extra pane of glass, enabling it to deliver improved insulation and better noise control.

If your property is in an exposed area, at a greater altitude, facing north, or close to a busy road or flight path, The Advanced Group would be more than glad to talk you through the advantages of triple glazing.
