If you’ve spotted a temperature drop in your house, or seen your bills going up, or condensation forming on or inside your windows in the morning, it’s worth paying attention.
Does that hit home? Your windows are telling you it’s time for a change.
Old windows drop their seal over time.
The gas between the panes escapes, the rubber gaskets go rigid and shrink, and what once did keep the cold out now barely slows it down.
In Craigmillar, where the rain and wind can seem more frequent than sunshine, tired windows truly change how warm and comfortable your home 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 the whole house of replacement windows and doors, we’ll help you find the right option and get it all fitted the right way.

Some issues are straightforward, such as cracked glass, rotten timber frames, and handles that don’t fasten the right way.
Other signs are harder to notice. By the time you do, they’ve been losing you money for months or years.

Can you notice moisture or fogging sitting between the two sheets of glass? That tells you the sealed unit has broken down.
The seal gives way, and with it goes the argon gas that delivered the insulation. The window loses a significant degree of its thermal performance.
Don’t pour money away with increasing heating bills and make sure to recover your home’s thermal performance with properly sealed new windows.

A windy day tells you everything. Place your hand near the edges of the window. Cold air getting through means the seals have worn away.
Draught proofing strips? They’re a temporary fix. The fault only worsens as the rubber keeps break down.

A window that jams, won’t lock right, or refuses to budge is not just an annoyance. It’s a security risk and an insulation problem. Warped frames, worn hinges, and failed mechanisms are the window’s way of telling you it’s finished.
Multi-point locking systems on modern windows provide far stronger protection than the single-point catches used in older windows, and toughened glass choices give an additional layer of safety.

Your windows are where a considerable proportion of your home’s heat is lost. That thin bridge between you and the outside elements counts more than many people expect.
Double glazing from the past is just that, in the past. The energy ratings sit significantly below today’s standards, even if the original spec was reasonable at the time.
Want to shield your house from those high energy bills? New double glazed windows and doors are the way forward.

Craigmillar houses come in all shapes and sizes, and the right window type depends on your house, the room, and how you use it.
The Advanced Group provides and fits a full choice of windows and doors in double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung designs.
Casement windows are likely the most popular window style in the UK. They’re side-hinged and open outwards, making them great for ventilation and straightforward to clean from inside.
They fit most styles of property, from modern builds to traditional villas, and come in a wide choice of colours and finishes. Woodgrain effects mimic the look of timber without the maintenance or fear of warping.

Our sliding sash windows are designed to replicate the appearance of original wooden sash frames, while delivering modern levels of thermal performance and safety.
Every proportion, sight line, and opening mechanism follows the traditional style. Whether your property is in a conservation area or you simply want to hold onto its charm, these windows do the job.
These windows provide two options: tilting inward at the top for protected ventilation, and turning fully inward on a side hinge for easy cleaning.
If you are in an upper-floor flat, these are a great choice because cleaning the outside of the glass from a ladder just isn’t practical.
The tilt mode delivers airflow without security worries. Particularly useful for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, giving a practical solution for ventilation that also helps to keep rain out.
They’re often installed in bathrooms, kitchens, stairwells, bay window setups, and other spaces where privacy and airflow are equally needed.

French windows are full-length windows that open outward, working much like French doors.
They’re great in pairs and can be matched with sidelights to flood a wide opening with glass and natural light.

We focus in uPVC frame materials. And for good reason.
uPVC frame materials are particularly well suited to the unforgiving Scottish weather, providing durability and resilience to rough, windy, and wet weather. Unlike timber frames, uPVC won’t suffer from the same warping or rot issues.
uPVC is low maintenance too.
Soapy water and a wipe. That’s all it takes to get uPVC looking fresh.
The real benefit? Energy efficiency. Our uPVC windows feature multi-chambered uPVC, and some frames hit a U-value as low as 0.8 W/m2K. That recovers proper energy performance to your property.
And you want to hear the better part? uPVC double glazing is also the most budget-friendly option available!
Higher-spec glazing without breaking the budget? That’s what uPVC allows. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to go with.

Cold, wet, and windy. That’s Scotland for a large chunk of the year.
In such a climate, the energy performance of your windows has a real effect on your heating bills and the overall cosiness of your home on a daily basis.
The thermal performance of a window is measured by its U-value.
A lower number means less heat being lost through the glass and frame. Currently, Scottish building regulations require a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows sit at 1.2 W/m2K. The premium models? As low as 0.8 W/m2K. Twice as good as the regulatory minimum, comfortably.
The difference shows up on your energy bills.
A-rated energy-efficient windows and doors feature argon gas filled sealed units and low-E glass coatings to reflect heat back into the room, all while allowing natural light through.
If you’re replacing old single-glazed sash windows or dated double glazing, you could see a noticeable drop in your heating spend within the first winter.
Craigmillar has plenty of double glazing firms. Few come close to the calibre of our windows and doors.

Our trusted installers are frequently asked about the triple glazing options we offer.
An extra pane of glass. Improved insulation. Better noise control. That’s triple glazing.
If your home is in an exposed area, up a hill, facing north, or near a busy road or flight path, The Advanced Group is more than willing to walk you through the upsides of triple glazing.

We totally get that new windows are an big purchase, and paying for them all at once isn’t always feasible.
That’s why we have 0% APR and up to 4 years of interest free credit, making the process much less stressful!
This enables you to obtain the windows you want while spreading the cost of your new windows and doors in a way that works for your budget.
