Homes in Scotland typically come in at £4,300–£8,600, VAT included, for this kind of work. We also cover Bangor, County Down, Larne and Carrickfergus, and the same steps apply wherever you are in Dumfries and Galloway.

Homes in Dumfries and Galloway
Dumfries is known for red sandstone buildings, and older towns across the region, such as Kirkcudbright and Castle Douglas, have Georgian and Victorian streets. Rural homes are often harled whinstone or sandstone farmhouses and cottages under slate roofs, with post-war and modern housing on the edges of towns such as Stranraer and Annan.
Stone and harled homes commonly need lime-based repairs, re-harling and roof slating work. Town houses suit extensions and loft conversions, and rural properties often take porches, driveways and fencing.
Building traditions across Dumfries and Galloway also raise conservation and planning questions, so we check those for replacement windows in Stranraer at the survey stage.
Planning and building rules in Stranraer
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Stranraer comes under Scotland, covered below, and we raise any questions with the council before your quote is finalised.
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.
From survey to handover
We look at the job
First, someone visits your home in Stranraer to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Written quote
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Plan and prepare
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
Build and hand over
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
What you can expect from us
Common questions
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from replacement windows, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
How much do replacement windows cost?
Replacement windows for a typical 3-bed semi cost £4,300–£8,600, depending on the number of windows, frame material and glazing. A single standard uPVC casement usually works out at roughly £500–£950 fitted, while aluminium, flush sash and sliding sash styles cost more. Bays, large panes and upstairs access add to the price. We measure every opening during the survey and give you a fixed price for the agreed specification.
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.
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.
How do I look after new uPVC or aluminium windows?
Caring for new windows is simple: wash frames and glass with warm soapy water a few times a year, avoiding abrasive cleaners and solvents. Clear the drainage slots at the bottom of the frame so rainwater can escape, and put a drop of light oil on hinges and locking points once a year. Check seals and the sealant around the outside every few years, and replace any that have cracked or shrunk.
