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

New Windows Hamilton
Quality Energy Efficient Double Glazed Windows & Doors




You’ve noticed the temperature shifting in your home. Heating costs are climbing. Condensation forms on or inside your windows each morning.
Does that ring true? Your windows are sending a signal they need replacing.
Windows don’t stay sealed forever, and older ones drop theirs over time.
The gas between the panes leaks out, the rubber gaskets stiffen and shrink, and what once kept the cold now barely does anything.
Living in Hamilton, you get that rain and wind can outweigh the sunny days, and ageing windows make a real difference to how warm and cosy your home feels.
Not to worry. The Advanced Group has over 38 years of trusted service. Single room or full house, replacement windows or doors, we’ll find the right option and install everything properly.

Some signs are straightforward, such as cracked glass, rotten timber frames, and handles that won’t lock correctly.
Some signs slip under the radar however, and by the time you spot them, they’ve been steadily costing you money for months or even years.

If you can see moisture or fogging between the two sheets of glass, this is a strong sign that the sealed unit has failed.
Once the seal has failed, the argon gas that delivers insulation escapes, and the window loses a significant portion of its thermal efficiency.
Why throw money away on increasing heating prices? Bring back your home’s thermal efficiency with well sealed new windows today.

A windy day shows you all you need to know. Hold your hand near the edges of the window. Cold air sneaking through tells you the seals have deteriorated.
Draught proofing strips can help temporarily, but they’re a sticking plaster on a problem that will only deteriorate as the rubber continues to degrade.

Sticking windows that won’t fasten properly aren’t just inconvenient, they’re a security risk and an insulation issue too. Warped frames, worn hinges, and failed mechanisms all suggest a window that’s reached the end of its useful life.
Multi-point locking systems on newer windows deliver far better safety than the single-point catches found on older frames, and toughened glass options provide an extra layer of security.
Windows lose a significant share of your home’s heat. They’re the barrier between you and the outside weather.
Older double glazing is a thing of the past, and the energy ratings will be significantly below what’s on offer now, even if they were a decent specification when they were first fitted.
New double glazed windows and doors will protect your home from high energy costs.

The right window style for your Hamilton home will depend on the property itself, the room in question, and how you use it.
We supply 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.

The most common window type in the UK. Side-hinged, opening outwards. Great for ventilation and easy to clean from inside.
They suit most kinds of property, from modern builds to traditional villas, and are available in a wide range of colours and finishes. Woodgrain effects replicate the look of timber without the maintenance or risk of warping.

Our sliding sash windows are designed to mirror the appearance of original wooden sash frames, while offering modern levels of thermal efficiency and security.
The proportions, sight lines, and opening mechanism all match the traditional look, which is brilliant if your property’s in a conservation area or you just want to hold onto its character.

These windows provide two modes: tilting inward at the top for secure ventilation, and turning completely inward on a side hinge for straightforward cleaning.
They’re particularly common in upper-floor flats, where getting up a ladder to clean the outside of the glass is not an option.
Airflow without the safety risk of a fully open window. That’s what the tilt mode provides, and it’s particularly valuable for families with young children.
Hinged at the top, swinging outward from the bottom. Top hung windows give you ventilation and help block the rain out at the very same time.
You’ll often find them in bathrooms, kitchens, stairwells, and bay window configurations, places where both privacy and airflow count.

Full-length windows that open outward like French doors. That’s exactly what French windows are.
They’re ideal in pairs and can be paired with sidelights to open up a wide opening with glass and natural light.
uPVC frame materials. That’s what The Advanced Group focuses in, and the reasons are solid.
uPVC frame materials are especially well suited to the tough Scottish climate, offering durability and resistance to wild, windy, and wet weather. Unlike timber frames, uPVC won’t suffer from the same warping or rot concerns.
On top of that, uPVC is really low maintenance.
Just a simple wipe with soapy water and it can look brand new!
Here’s the really big part: our uPVC windows are highly energy efficient! Made with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, which really helps restore your home’s energy efficiency.
The cherry on top? uPVC double glazing is the most budget-friendly option available.
So you can often install premium-grade glazing and still keep within budget. We supply glazed uPVC doors too, including uPVC doors, composite doors, and patio doors to complement.
Let’s be real, Scotland is cold, wet, and windy for a good chunk of the year!
In that environment, the energy efficiency of your windows makes a measurable difference to how much you shell out on heating and how warm your house feels every day.
U-value. That’s the figure that shows you how thermally efficient a window truly is.
Lower number, less heat getting out. Scottish building regulations currently set a maximum of 1.6 W/m2K for replacement windows.
Our standard double glazed windows sit at 1.2 W/m2K. The premium range? As low as 0.8 W/m2K. Twice as effective as the regulatory minimum, without question.
That difference is visually visible on your energy statements.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are fantastic at reflecting heat back into the room while still allowing plenty of light through.
Moving from old single-glazed sash windows or 1990s double glazing? You could see a significant drop in heating spend within the first winter.
Many double glazing businesses in Hamilton offer standard products, but few can match the calibre of the windows and doors we supply.

Our trusted installers are regularly asked about the triple glazing options we carry.
Triple glazing includes an extra pane of glass, which delivers enhanced insulation and noticeably greater noise control.
If your property is located in an exposed location, up a hill or high above sea level, facing north, or near a busy road or under a flight path, The Advanced Group would be more than glad to guide you through the benefits of triple glazing.

New windows are an significant purchase, and we understand that paying for them all at once isn’t always realistic.
That’s why we have 0% APR and up to 4 years of interest free credit, making the purchase much less stressful!
