North Glasgow's housing stock is a mixed bag, and that shapes almost every window job. Springburn, Possilpark and Maryhill have plenty of red and blonde sandstone tenements, many of them in conservation areas or listed, where the rules on replacing sash and case windows are strict. Further out, Bishopbriggs, Lenzie and Bearsden lean towards 1930s semis, post-war bungalows and larger detached villas, where uPVC and aluminium double glazing are far more common. Then there are the council-era flats and maisonettes around Milton and Balornock, where installers often deal with several windows at once and tight stairwell access. Wind and driving rain off the hills mean draught-proofing and good sealing matter more than you'd think.
The businesses on this page were drawn from third-party business listings and ranked by public review rating and review count, with a small lift for those showing a working website and phone number. We read each business's homepage to confirm window installation is what they primarily offer, which keeps unrelated trades off the page. Listings flagged as permanently closed are removed automatically. Where you see a Trust Verified badge, that business has additionally passed our full verification covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. Our How We Verify page has the full list. For anyone without that badge, those checks haven't been done by us, so you'll want to do them yourself before booking.
Start by asking every installer for a written, itemised quote that names the glass specification, frame material, opening style and what happens to your old windows. Ask whether they're registered with FENSA or CERTASS, and if so, ask for the registration number so you can check it directly. Once the job's done you should get a certificate confirming the work meets building regulations, which you'll need when you sell. Check the length of the guarantee and who stands behind it if the firm closes. Get two or three quotes, as prices for near-identical jobs can vary by several hundred pounds, and don't pay a large deposit upfront.

How much do window installers cost in North Glasgow?
For standard uPVC double glazing, expect roughly £300 to £600 per window depending on size and style, so a typical three-bed semi in Bishopbriggs might come in around £3,500 to £6,500 for the whole house. Aluminium and timber cost more, often £700 to £1,500 or above per window. Sash and case replacements in a Maryhill or Springburn tenement can run from £1,200 to £2,500 each, particularly in conservation areas. Glass spec, frame colour, opening style and fitting access all move the price. Getting two or three itemised quotes is normal and worth doing.
Do I need planning permission or a warrant to replace my windows?
Often you don't for a like-for-like replacement in a modern house, but flats, listed buildings and conservation areas are different. Many North Glasgow tenements sit under rules that restrict frame material and design, and in flatted properties the factor or other owners may need to agree. Check with Glasgow City Council before you commit, and ask your installer whether they've worked on similar properties nearby.
How long does a typical window installation take?
A single window usually takes a couple of hours. A full house of eight to twelve windows is normally done in one to two days by a two-person crew. Bay windows and French doors add time. Lead times for made-to-measure frames are generally two to six weeks, longer for timber or aluminium, so don't plan around a quick turnaround.
What's the difference between uPVC, aluminium and timber windows?
uPVC is the cheapest and lowest maintenance, which suits most suburban houses around Lenzie and Bishopbriggs. Aluminium has slimmer frames and a modern look, and costs more. Timber suits period properties and conservation areas, but needs repainting every few years. Whatever you choose, ask for the U-value or energy rating on the quote so you can compare like with like.
What guarantees and paperwork should I get?
You should receive a written guarantee covering frames, glass units and hardware, commonly ten years or more on frames and sealed units. Ask who backs it if the company stops trading, as some use an insurance-backed scheme. You should also get a compliance certificate for the installation, usually via FENSA or CERTASS if your installer is registered, or confirmation of building warrant sign-off where one was needed. Keep all of it together with your invoice.
How do I check a window installer before hiring them?
Ask for their FENSA or CERTASS registration number and look it up with the scheme itself. Request proof of public liability insurance and check the cover amount and dates. Search the company name in Companies House to confirm it's active, and read recent online reviews, paying attention to how they handled problems. Ask to see photos of recent work or visit a local job if you can. Be wary of anyone who pushes you to sign on the day or demands a big cash deposit. Businesses without a Trust Verified badge on this page haven't been independently verified by us, so these checks are down to you.
