Exeter's housing mix throws up a fair few different jobs for window installers. You've got Victorian terraces around St Leonard's and Newtown with sash windows needing careful like-for-like replacement, 1930s semis out towards Pinhoe and Whipton where the original steel or timber frames have often had their day, and newer estates in Cranbrook and Monkerton where it's more a case of upgrading standard double glazing to something with better thermal performance. Add in the odd listed building near the Cathedral Quarter, where planning restrictions dictate what you can and can't fit, and it's clear that finding an installer who knows the area's quirks matters more than it might elsewhere.
The businesses featured here are pulled from public business listings and ranked mainly by review rating and how many reviews they've built up, with a small lift given to those showing a working website and phone number. We check each business's homepage as well, to confirm window installation is genuinely what they do day to day, which keeps roofers, general builders and glaziers who dabble occasionally off this particular list. Any listing flagged as permanently closed gets removed automatically so you're not chasing a firm that's shut up shop. 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 any business without the badge, those checks haven't been done by us, so it's worth doing your own homework before you commit.
Before signing anything, ask to see FENSA or CERTASS registration, since this covers the building regulations sign-off for replacement windows and saves you dealing with local authority paperwork separately. Get a written guarantee, ideally insurance-backed, and check what it actually covers, whether that's the glass units, the frames, or just the fitting. It's worth getting two or three quotes for anything beyond a single window, because prices for a full house re-glaze can vary by thousands depending on frame material and finish. Ask how long the job will take, whether they're removing and disposing of the old frames, and what happens if they hit rot or damp in the surrounding brickwork once the old windows come out.
How We Select & Rate The Best Window Installers in Exeter
Rankings on this page are based on review rating and review count taken 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, which filters out unrelated trades. Listings marked as permanently closed are removed automatically. Businesses carrying a Trust Verified badge have additionally passed our full verification, covering trade qualifications, insurance, trading history, and customer review history; see our How We Verify page for full details. Other businesses have not been independently verified by us, and appearing on this page isn't an endorsement. Always carry out your own checks before hiring.

A single uPVC casement window swapped for like-for-like typically runs from around £400 to £700 fitted, while a full house of six to eight windows in uPVC often lands between £3,500 and £6,000 depending on style and glazing spec. Timber sash replacements cost more, often £900 to £1,500 per window given the joinery involved, and aluminium frames sit somewhere in between. Bay windows, and anything needing scaffolding on a first floor terrace, push the price up. Get two or three quotes, since fitting costs and lead times vary a fair bit between installers in Exeter.
Do I need planning permission to replace windows in Exeter?
Most straightforward replacements fall under permitted development and just need building regulations compliance, usually handled through a FENSA or CERTASS certificate rather than planning permission. If your property is listed, or sits within one of Exeter's conservation areas such as parts of St Leonard's or the Cathedral Quarter, you'll likely need listed building consent or conservation area approval before changing window style, materials or glazing bars. Check with Exeter City Council's planning department if you're unsure, and ask your installer whether they've dealt with conservation area jobs before.
How long does window installation take?
A single window usually takes half a day to fit. A full house re-glaze with six to ten windows generally takes two to four days, sometimes longer if there's rot in the surrounding frames or brickwork that needs sorting first. Bay windows and anything requiring scaffolding add time. Ask your installer for a day-by-day breakdown before work starts so you know when rooms will be out of use.
What's the difference between uPVC, timber and aluminium windows?
uPVC is the cheapest and lowest maintenance option, good for most modern and semi-detached properties around Exeter. Timber suits period homes and conservation areas better, but needs repainting or resealing every few years and costs more upfront. Aluminium gives slimmer frames and a more contemporary look, often used for larger glazed areas or bifold doors, and it holds up well, though it's typically pricier than uPVC. Your choice often comes down to the age of the property and whether you're in a conservation area with restrictions on materials.
Will new windows actually cut my heating bills?
Upgrading single glazing or tired 1980s double glazing to modern A-rated units with argon-filled cavities makes a noticeable difference to draughts and heat loss, particularly in older Exeter properties with solid brick walls and no cavity insulation. Savings on the boiler bill vary depending on how many windows you're replacing and the property's overall insulation, so don't expect it to solve everything on its own if the loft and walls haven't been looked at too. Ask your installer for the U-value of the glazing they're quoting, and compare that figure between quotes.
How do I choose between window installers in Exeter?
Start by asking to see their FENSA or CERTASS registration number and check it directly on the relevant register rather than taking their word for it. Ask for public liability insurance details and a copy of their guarantee terms, including whether it's insurance-backed in case the company stops trading. Look at recent customer reviews rather than just the overall star rating, since patterns in complaints about missed appointments or poor finishing are worth knowing. Get quotes in writing, not just a verbal price, and check exactly what's included, such as disposal of old frames, making good to plaster or brickwork, and VAT. If a business carries a Trust Verified badge on this page, that means it's passed additional checks on qualifications, insurance and trading history; for anyone without it, doing this legwork yourself before booking is sensible.
