Maybe you’ve felt a change in temperature around your house. Bills climbing. Or condensation collecting on or inside your windows each morning.
Sound familiar? Your windows are sending you a clear sign.
Older windows drop their seal over time.
Gas leaks from between the panes. The rubber gaskets harden and contract. What used to block the cold now barely makes a difference.
Living in Preston, you know that rain and wind sometimes outnumber the sunny days, and tired windows make a proper difference to how warm and comfortable your house feels.
No need to panic about it! The Advanced Group has been helping homeowners for over 38 years. Whether you are after new windows for just one room or every room of replacement windows and doors, we’ll guide you to the right option and get it all fitted the right way.

Cracked glass? Rotten timber frames? Handles that don’t fasten properly? Some problems are easy to spot.
But other signs are less obvious, and by the time you catch them, they’ve already been costing you money for months or even years.

Moisture or fogging between the two sheets of glass is a classic sign. The sealed unit has failed.
Once the seal has gone, the argon gas that delivers insulation escapes, and the window loses a significant chunk of its thermal performance.
Why waste money away on increasing heating prices? Recover your home’s thermal performance with perfectly sealed new windows instead.

On a windy day, put your hand near the edges of the window. If you can feel cold air getting through, this means the seals have broken down.
Draught proofing strips? They’re a short-term fix. The problem only worsens as the rubber continues to break down.

Got windows that jam, won’t fasten right, or just refuse to play along? That’s a security risk and an insulation problem rolled into one. Warped frames, worn hinges, and failed mechanisms all tell you the window has hit the end of its working life.
Multi-point locking systems far exceed the old single-point catches for protection. Toughened glass provides another layer of safety.

Windows account for a significant amount of heat loss in any house. Your window is the barrier between you and the outside world.
Older double glazing is a thing of the past, and the energy ratings will be significantly below what’s available now, even if they were a good specification when they were first put in.
Want to protect your property from those high energy costs? New double glazed windows and doors are the way forward.

No two Preston homes are the alike, and the right window style comes down to on the building, the room, and how you live in it.
The Advanced Group offers and fits a full choice of windows and doors in both double glazed and triple glazed configurations, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung types.
Quite likely the most common window style in the UK, casement windows are side-hinged and open outwards, which makes them great for ventilation and easy to clean from inside.
Casement windows suit just about every property style, whether it’s a modern home or a traditional villa! They come in a huge range of colours and finishes, and the woodgrain effects look just like real timber without the maintenance or warping risk.

Our sliding sash windows recreate the look of original wooden sash frames while offering modern thermal efficiency and security.
The proportions, sight lines, and opening mechanism all match the traditional design, which matters if your property is in a conservation area or you simply want to maintain its charm.
These windows tilt inward at the top for protected ventilation and turn completely inward on a side hinge for easy cleaning.
If you are in an upper-floor flat, these are a fantastic pick because cleaning the outside of the glass from a ladder just isn’t an option.
The tilt function allows air in without the security worries of having the window fully open, which is particularly useful if you’ve got young children.
Top hung windows are hinged at the top and open outward from the bottom, making them a sensible choice for ventilation while working to keep rain out.
They’re often used in bathrooms, kitchens, stairwells, bay window configurations, and other spaces where privacy and airflow are just as needed.

French windows are full-length units that open outward, operating much like French doors.
In pairs, they work brilliant, and you can pair them with sidelights to flood a wide opening with glass and plenty of natural light.

There are sound reasons why The Advanced Group focuses in uPVC frame materials.
Scottish weather throws all sorts at your windows. uPVC is built to handle it, hardwearing, resilient to harsh, windy, wet weather, and without the warping or rot concerns that affect timber frames.
And there’s one more benefit: uPVC is really low maintenance!
Just grab it a wipe with soapy water and it’ll look fresh.
But more significantly, our uPVC windows are extremely energy effective. Designed with multi-chambered uPVC, some of our frames can achieve a U-value as low as 0.8 W/m2K, helping restore energy efficiency to your home.
And the better part? uPVC double glazing happens to be the most affordable option available.
This allows you to often fit premium-grade glazing without blowing your budget. We also provide glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.

Let’s be straight, Scotland is cold, wet, and windy for a large chunk of the year!
In such a climate, the energy performance of your windows has a noticeable influence on your heating costs and the overall warmth of your property day to day.
A window’s thermal performance is measured by something called its U-value.
A lower U-value translates to less heat escaping 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 perform at 1.2 W/m2K. The premium options? As low as 0.8 W/m2K. Twice as good as the regulatory minimum, comfortably.
That performance gain is directly visible on your energy costs.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings reflect heat back into the room while still letting light through.
If you’re replacing old single-glazed sash windows or early double glazing, you could notice a noticeable drop in your heating spend within the first winter.
There are loads of double glazing businesses in Preston supplying standard products, but not many can rival the calibre of what we install.

Our experienced installers are regularly asked about our triple glazing options.
With an extra pane of glass, triple glazing delivers enhanced insulation and improved noise reduction.
If your house is in an exposed location, up a hill, facing north, or near a busy road or flight path, The Advanced Group is more than happy to talk you through the benefits of triple glazing.

New windows are an significant purchase, and we appreciate that paying for them all at once isn’t always practical.
So we make available 0% APR and up to 4 years of interest free credit. No fuss.
Get the windows you want. Spread the cost in a way that works for you.
