Replacement windows are new frames and sealed double- or triple-glazed units fitted into your existing openings after the old windows are taken out, improving warmth, security and noise reduction while meeting current building regulations.
We handle replacement windows as a managed project across Aberdeen and Aberdeenshire: one contract, one contact, and trades working to an agreed specification. Coverage includes Aberdeen, Peterhead, Nigg and Inverurie and their surroundings. In Scotland the consent rules have their own details, which we check for you. Typical prices in Scotland fall within £4,300–£8,600, VAT included, and are fixed in writing after a survey.

Homes in Aberdeen and Aberdeenshire
Aberdeen is built largely of grey granite, from tenements and terraces to granite villas in the West End, with post-war council housing and newer estates on the outskirts. Across Aberdeenshire, harled stone cottages, fishing-town terraces in Peterhead and Fraserburgh, and modern developments in commuter towns such as Westhill and Ellon are common.
Granite walls need repointing with a mortar matched to the stone, and slate roofs often want attention after hard winters. Harled cottages need breathable finishes, while newer estates commonly add extensions, garage conversions and driveways.
Cold North Sea winds, coastal haar and hard winter frosts are routine, so roofs, harling and exposed fixings need a robust specification.
Planning and building rules in Aberdeen and Aberdeenshire
Homes in Aberdeen and Aberdeenshire come under the regulations for Scotland, summarised below. We don't rely on general rules alone: we confirm the position for your address with the council before a quote goes out.
In Scotland, replacing windows and doors on a house generally needs no planning permission when the style is similar, but listed buildings and conservation areas are closely controlled and often need consent for any change of material or pattern.
A building warrant is not usually needed for like-for-like replacement windows, but the new units must still meet the Scottish building standards, including energy performance and, where relevant, escape from upper floors.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for replacement windows so the price reflects your home.
Your fixed price
After the survey we send a quote for replacement windows that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Booking the work
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for replacement windows are in place before the first day on site.
Build and hand over
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
What you can expect from us
Questions about replacement windows in Aberdeen and Aberdeenshire
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
How long will replacement windows take?
On a typical home, allow 1–2 days on site for a typical house. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
Do I need planning permission for new windows?
Planning permission is not usually needed to replace windows with similar ones, but it depends on the size and style of the change, your home's location, whether it is listed or in a conservation area, and which UK nation you live in. Listed buildings normally need consent for any change, and some conservation areas restrict uPVC or new styles. Flats may also need the building owner's approval. We check the position for your property before quoting.
How long does it take to fit windows in a house?
Fitting replacement windows in a typical 3-bed house usually takes one to two days on site. We take out and fit one window at a time, so each room is weathertight again within an hour or two. Bays, sash windows and homes needing scaffolding take longer. Manufacture comes first: made-to-measure frames typically take a few weeks to arrive after the survey and your order are confirmed.
Should I choose uPVC or aluminium windows?
uPVC windows are the lower-cost choice, insulate well and need only occasional cleaning, which suits most houses. Aluminium windows have slimmer frames that let in more light and suit modern homes or large openings, but they cost more. Both come in a wide range of colours and finishes. We usually recommend matching the style and proportions of your home's original windows, especially on period properties.
