Dundee's housing stock is a real mix, and that shapes what people need from a window installer. You've got the sandstone tenements around Stobswell and Hilltown with their original sash and case windows, the post-war semis out in Downfield and Fintry that mostly have older uPVC needing replaced, and newer builds near Dundee Waterfront where it's more about snagging or upgrading to triple glazing for energy efficiency. Coastal weather off the Tay adds another factor too, driving rain and salt air don't do window seals any favours, so a lot of the work here is repairs and reseals as much as full replacements. Whatever your street looks like, the right installer will know Dundee's building styles and won't try to sell you a one-size-fits-all solution.
The businesses featured on this page come from public business listings, ranked mainly by review rating and how many reviews they've built up, with a small boost for those who have a working website and phone number listed. We also read through each business's homepage ourselves to check that window installation is genuinely their main line of work, which keeps roofers, general builders and glaziers who only do the odd window job off this list. Any listing flagged as permanently closed gets removed automatically, so you shouldn't find dead ends here. Where you spot a Trust Verified badge next to a business, that firm has gone through our fuller verification process, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. You can read exactly what that involves on our How We Verify page. For any business without that badge, we haven't independently checked those things ourselves, so it's worth doing that legwork before you book.
Before you commit to anyone, ask to see their FENSA or Certass certification, since window replacements in Scotland need to comply with building regulations and a proper installer will register the work. Ask about the warranty on both the frames and the glazing units, ten years is fairly standard for uPVC, and check whether it's insurance-backed in case the company folds. It's also worth asking what happens with your old windows, some installers include removal and disposal in the price, others charge extra. Get at least two or three quotes for anything beyond a small repair. Prices can vary by hundreds of pounds for what sounds like the same job, and a written, itemised quote makes it much easier to compare like for like.
How We Select & Rate The Best Window Installers in Dundee
Rankings are based on review rating and review count pulled from public business listings, with a modest lift given to businesses that have a working website and phone number. We check each business's homepage to confirm window installation is their primary trade, rather than a side service offered by a general builder or glazier. Listings marked as permanently closed are removed automatically. Businesses displaying a Trust Verified badge have gone through our full verification process, covering qualifications and accreditations, public liability insurance, trading history, customer review history and registered company details, see our How We Verify page for the complete list. Other businesses on this page haven't been independently verified by us, and appearing here isn't an endorsement. Always carry out your own checks before hiring.

A single uPVC window replacement typically runs from around £400 to £700 depending on size and glazing type, while a full house re-glaze (say eight to ten windows) can land anywhere between £4,000 and £8,000. Sash and case restoration in Dundee's older tenement flats tends to cost more, often £600 to £1,200 per window, because of the joinery involved. Triple glazing adds a premium of roughly 15 to 20% over standard double glazing. Prices shift based on frame material, access (tenement flats above ground floor often need extra scaffolding or hoisting), and whether you're doing a full house or just one or two windows. Get two or three quotes, since the range you'll see for a similar job can be surprisingly wide.
Do I need planning permission or building warrant for new windows in Dundee?
Most straightforward like-for-like window replacements don't need planning permission or a building warrant, they're covered by permitted development rights. However, if your property is listed or in a conservation area, which covers parts of the West End and Broughty Ferry, you may need conservation area consent, particularly if you're changing from timber sash to uPVC. It's worth checking with Dundee City Council's planning department before work starts, and any reputable installer should flag this for you rather than leave you to find out later.
How long does window installation take?
A typical domestic job, replacing eight to twelve windows in a standard semi or terrace, usually takes one to two days once the windows themselves have been manufactured. Sash and case restoration takes longer per window because of the joinery and paint work involved. The bigger factor is lead time before the job starts, made-to-measure uPVC or timber windows often take three to six weeks to manufacture, so don't expect same-week installation unless it's a small repair.
What's the difference between uPVC, timber and aluminium windows?
uPVC is the most common choice for Dundee homes because it's low maintenance and reasonably priced, typically £400 to £700 per window. Timber, including traditional sash and case, suits older tenements and conservation areas but needs repainting every few years and costs more upfront. Aluminium is slimmer in profile and increasingly popular for contemporary extensions or larger glazed areas, but it carries a higher price tag and can feel colder to the touch unless it's thermally broken. Which one's right depends on your property type, your budget and whether you're restricted by conservation rules.
Can a window installer fix condensation or draughts without full replacement?
Often, yes. Failed seals on double glazing (that misty look between panes) usually means the sealed unit needs replacing rather than the whole window, which is much cheaper, often £100 to £250 per pane. Draughts are sometimes down to worn weatherstripping or a dropped hinge rather than a failed window, and a good installer can repair or adjust these on-site. It's worth getting a repair quote alongside a replacement quote so you can compare, since full replacement isn't always necessary.
How do I choose between window installers in Dundee?
Start by asking for their FENSA or Certass registration number and checking it's valid, this confirms the work will comply with building regulations. Ask for photos of previous jobs in similar Dundee properties, especially if you've got sash windows or a conservation area restriction. Check what warranty they offer on frames and glazing, and whether it's insurance-backed. Look at recent reviews rather than just the overall rating, since a pattern of complaints about missed appointments or poor finishing is worth knowing about. Finally, get a written itemised quote from at least two or three installers before deciding, and don't be afraid to ask what's included, such as removal of old windows, making good to plaster, or silicone finishing.
