Aberdeen's housing stock throws up a fair few challenges for window installers. You've got granite tenements in the West End with their original sash and case windows, semi-detached bungalows out in Bridge of Don and Kingswells that mostly went uPVC decades ago, and newer builds in Countesswells and Cove that need modern double or triple glazing to cope with the coastal wind coming off the North Sea. Anyone quoting for work here needs to know the difference between listed building restrictions in Old Aberdeen or the conservation areas around Rubislaw, and the more straightforward replacement jobs you'd find in Dyce or Portlethen. Weather matters too. The city gets battered by driving rain and salt air, so seals, frames and drainage all need to be up to the job, not just fitted to look tidy.
The businesses listed here were pulled from public business listings and ranked mainly by review rating and how many reviews they've built up, with a small boost given to those showing a working website and phone number. We then read through each business's homepage to check that window installation is genuinely what they do day to day, which keeps general builders or handymen who dabble in windows off this page. Any listing flagged as permanently closed gets stripped out automatically. Where you spot a Trust Verified badge, that business has gone further and 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 sets out exactly what that involves. For businesses without the badge, none of that has been independently checked by us, so it's worth doing that homework yourself before signing anything.
Before you commit to an installer, ask to see their FENSA or CERTASS certification, since this confirms the work complies with building regulations without you needing a separate council inspection. Check what guarantee comes with the frames and the glazing units, insurance-backed guarantees are worth more than a company's own paper promise if they go bust. Get at least two or three written quotes rather than a single verbal figure, and make sure each one specifies the exact glazing spec (U-values, gas fill, spacer bars) so you're comparing like for like. It's also sensible to ask how they'll handle disposal of old frames and whether scaffolding or access equipment is included, since that can quietly add a few hundred pounds if it's sprung on you afterwards.
How We Select & Rate The Best Window Installers in Aberdeen
Ranking is driven by review rating and review count from public business listings, with a small lift given to businesses that show a working website and phone number. We check each business's homepage to confirm window installation is what they primarily offer, so unrelated trades don't appear on this page.

How much does a window installers cost in Aberdeen?
A single uPVC window replacement typically runs from around £450 to £800 depending on size and glazing spec, while a full house of six to eight windows usually lands somewhere between £3,500 and £7,000. Timber sash and case windows, common in the granite tenements around Rosemount and the West End, cost more, often £900 to £1,500 per window, because of the joinery involved and conservation area requirements. Aluminium frames sit in the middle, popular for bigger openings or bifold doors. Prices vary with frame material, glass type (double versus triple glazing), and access difficulty on tenement flats. Getting two or three quotes is normal practice and helps you spot anyone pricing well above or below the local going rate.
Do I need planning permission to replace windows in Aberdeen?
Most straightforward replacements, like swapping an old uPVC window for a new one of similar style, don't need planning permission under permitted development rights. It's a different story if your property is listed or sits within a conservation area, which covers parts of Old Aberdeen, the West End and Rubislaw. There, you may need listed building consent even for like-for-like replacements, and the council can be strict about retaining timber sash and case designs. Check with Aberdeen City Council's planning department before ordering anything if you're unsure, since installing without consent when it's needed can mean costly remedial work later.
How long does window installation take?
A standard uPVC window replacement usually takes half a day to a full day per window, so a typical semi-detached house might be finished in one to two days. Larger jobs, full house re-glazing or properties needing scaffolding for upper floors, can stretch to a week. Timber sash and case restorations take longer still, since original frames often need careful repair rather than straight replacement. Weather can cause delays too, particularly with exposed properties near the coast in Torry or Bridge of Don, so build in some flexibility around your expected finish date.
What's the difference between FENSA and CERTASS certification?
Both schemes let installers self-certify that replacement windows and doors meet building regulations, sparing you the cost and hassle of a separate council building control inspection. FENSA is the older, more widely recognised scheme, while CERTASS covers similar ground with slightly different membership criteria. What matters practically is that your installer is registered with one of them and provides you with a compliance certificate after the job, which you'll need if you ever sell the property. If an installer can't provide either, ask how they're handling building regulations sign-off instead.
Should I choose double or triple glazing in Aberdeen?
Double glazing is still the standard choice and suits most Aberdeen properties fine, keeping heating costs down against the city's damp, windy climate. Triple glazing offers better thermal performance and noise reduction, worth considering for exposed spots near the coast or busy roads like Anderson Drive, but it costs more upfront and adds weight to frames, which isn't always practical on older buildings. For most semi-detached and terraced houses in areas like Mannofield or Cults, double glazing with a decent U-value strikes a sensible balance between cost and performance.
How do I choose between window installers in Aberdeen?
Start by checking each installer's FENSA or CERTASS registration number directly with the scheme, rather than just taking their word for it. Ask for proof of public liability insurance and find out whether guarantees are insurance-backed, which protects you if the company stops trading. Read through recent customer reviews, not just the star rating, to see how they handle problems when things go wrong. Get written quotes from at least two or three installers with matching specifications so you're comparing fairly, and ask for photos or addresses of previous local jobs you could look at. Doing this legwork yourself before booking is the best protection you have.
