Should I choose uPVC, timber, or aluminium frames?

It depends on your budget, the style of your home, and maintenance tolerance. uPVC is the most common and cheapest (£300-600 per window fitted). It's low-maintenance, thermally decent, and lasts 20-30 years. It doesn't suit listed properties or period homes where authenticity matters. Timber frames are more expensive (£600-1200 each) and need regular painting, but they look right on Victorian or older homes and can be repaired rather than replaced. Aluminium sits between — modern look, strong, low maintenance, but costs more upfront (£500-900 per window). In Bridgend's climate, uPVC is the practical choice for most properties. If your home is listed, check with Bridgend Council's planning team about restrictions before deciding.

How do I know if my windows need replacing?

Look for these signs: condensation trapped between panes (seals have failed), draughts you can feel when you're near the frame, sticking frames that won't open smoothly, visible rot or soft wood around the edges (especially on timber), or frames visibly warped. Single glazing is inefficient but doesn't automatically need replacing — double glazing alone won't solve a cold home if walls or roof are poorly insulated. Before replacing windows, check your insulation and heating system. If frames are sound and sealed but your home's cold, windows might not be the priority. A good trader will be honest about this. Get a surveyor's opinion if you're unsure whether the job's necessary or if you're dealing with structural issues like rotten lintels.

What Building Regulations do I need to know about?

Window and door replacement technically requires Building Regulations approval in Wales. Your installer should handle this via Fensa or CERTASS registration, which certifies the work meets current standards (mainly thermal performance and safety). If they're registered, you get a completion certificate automatically — this matters when you sell. If they're not registered, you need a Building Control sign-off separately, which costs extra and is slower. Listed properties or conservation areas have planning restrictions too — you'll need planning permission for some styles or materials. Ring Bridgend Council's planning team before specifying frames on older properties. Emergency repairs (replacing broken glass, fixing hinges) don't need approval, but frame replacement does. Always clarify this in writing before booking to avoid disputes about who arranges what.

What warranty should I expect and what does it actually cover?

Standard warranties are 10 years on the frames (manufacturer) and 2-5 years on labour (installer). Read the small print — some exclude wear items like hinges or exclude damage from impact, weather, or poor maintenance. A good warranty means the trader stands behind their work and the manufacturer behind their product. Fensa or CERTASS registration includes a 10-year guarantee on the installation itself, which is separate from frame warranties. Check what you actually get: are frames guaranteed against failure, discolouration, or just manufacturing defects? Labour warranties cover installation errors — poor sealing, misaligned frames, hinges failing prematurely. Ask specifically whether the warranty covers call-backs or if you're charged for fixing issues within the warranty period. Get warranty terms in writing before you book. Cheap quotes sometimes come with weak or no guarantees — that's a red flag.

How much will new windows actually reduce my heating bills?

Realistically, replacing old single glazing with modern double glazing saves about 10-15% on heating bills, depending on how much glazing you're replacing and your home's other insulation. If your home has poor wall or roof insulation, new windows alone won't make a huge difference — you're addressing only one part of heat loss. The bigger saving comes if you're replacing old, draughty frames where air leaks as much as heat. Modern sealing and low-emissivity glass help, but windows are just one element. For the best return, consider insulation first: loft insulation is cheaper and often gives better results. Windows matter for comfort (less draughts, condensation) as much as bills. Don't expect windows alone to transform your heating costs unless your current frames are severely compromised. A surveyor can advise on your home's priorities. New windows do improve comfort immediately though — no draughts, better temperature consistency, and less noise.

Why Get Windows and Doors Right in Bridgend

Windows and doors are one of the biggest decisions you'll make on your home. Get them wrong and you're looking at draughts, condensation, noise from the road, and energy bills that won't budge. Get them right, and you've sorted heating bills, security, and honestly, your home just feels better.

In Bridgend, you've got a mix of older terraces, semi-detached homes, and newer builds. A lot of the older stock still has single-glazed frames or tired double glazing that's seen better days. Whether you're replacing tired windows, upgrading to modern frames, or fitting new doors to the side or back, you need someone who knows the work, does it properly, and stands behind it.

This guide walks you through what to expect, what it costs, what accreditations matter, and the exact questions to ask before you hire. We're keeping it straightforward — no jargon, just what you need to know to make a solid decision.

What Windows and Doors Cost in 2026

Prices vary massively depending on what you're after. Here's what you're realistically looking at:

Upvc windows (most common choice): £300-£600 per window fitted, depending on size. A standard three-bedroom semi might need 6-8 windows, so you're looking at £2,000-£4,500 total. Timber frames cost more — £600-£1,200 each fitted. Aluminium sits in between.

Composite or upvc doors: £600-£1,500 fitted for a front or back door. This includes frame, hardware, and fitting. Timber doors start at £800-£2,000+.

Bi-fold doors: £1,500-£4,000+ fitted, depending on width and materials. These cost more because they're complex to hang and seal properly.

Patio or sliding doors: £400-£1,200 fitted depending on size and frame type.

These prices assume standard sizes and straightforward openings. If your frames are rotten, need structural work, or you're dealing with listed building restrictions (relevant in some Bridgend areas), costs rise. Installation complexity matters too — ground floor is cheaper than upper-floor work.

Always ask for a full quote in writing. A reputable trader will measure properly and break down materials, labour, and any site-specific costs. Avoid rock-bottom quotes — they usually mean corners being cut on seals, fixings, or finish. Mid-market pricing with a established trader typically offers the best value.

Accreditations That Actually Matter

Not all qualifications are equal. Here's what to look for:

TrustMark: The gold standard. Run by the government, TrustMark-registered traders meet strict standards for competence, customer service, and complaints handling. If a trader is TrustMark-registered, check their registration number on the TrustMark website — you can verify them instantly. This gives you genuine protection.

Fensa or CERTASS: If you're fitting new windows or doors with glazing, the installer should be registered with Fensa or CERTASS. These bodies handle Building Regulations compliance. Without this, you might struggle to prove the work meets current standards when you sell. Registration shows they're qualified and insured for the job.

Competent Person schemes: Look for certifications from bodies like the FMB (Federation of Master Builders) or relevant window and door manufacturer accreditation. These show the trader has been assessed and is up to date with standards.

Gas Safe or NICEIC: Only relevant if they're doing heating or electrical work alongside the windows or doors.

What to check: Ask for registration numbers, then verify them online. Don't accept "we're registered" without proof. A proper trader will have current Public Liability Insurance (usually £6 million cover minimum) and should provide a copy without hesitation. Ask how long they've been trading and ask for references — real ones from local jobs, not friends.

Bridgend-Specific Factors

Bridgend's housing stock is pretty mixed, which shapes what traders see most. You've got a lot of Victorian and Edwardian terraces in the older town areas, plus post-war semis and detached homes. Many of these still have original or aging wooden frames, and the Welsh climate — damp and windy — is hard on old frames. Rot, swelling, and failed seals are common issues.

The newer estates around Bridgend (Wildmill, Pencoed direction) tend to have uPVC already fitted, but 20-30-year-old uPVC is starting to fail: hinges wearing, seals cracking, frames warping in the sun. Replacement is increasingly common.

Weather matters here. Bridgend gets proper rain and wind off the Bristol Channel. Poor installation or cheap seals fail fast. Thermal performance also matters — a badly fitted or low-spec window loses heat quickly, and heating bills in winter feel it.

The Bridgend area has several established local traders, many with years of local work. The Welsh local authority building control is strict, especially on listed properties or conservation areas (there are several in Bridgend town centre). If your property falls into either category, check restrictions before specifying frames — some materials or styles won't be approved.

Lookout for traders familiar with local quirks: uneven openings in older properties, soft lintels, damp masonry. Someone who knows Bridgend homes will anticipate these and price and plan accordingly rather than creating surprises halfway through.

How to Find and Hire the Right Trader

Start local. Ask neighbours or friends in Bridgend who've had windows or doors done recently. Personal recommendations carry weight — you'll hear about someone's actual experience, not marketing speak.

Use directories like this one to find Bridgend-based traders with decent track records. Check their TrustMark status, read any reviews available, and note their contact details.

Getting quotes: Approach 2-3 traders. Each should visit, measure properly, and provide a written quote breaking down frames, glazing, hardware, installation, and any extras (removal, debris disposal, making good). Don't accept verbal quotes or estimates — get it in writing. Good traders are happy to do this; they know what they're quoting.

Comparing quotes: The cheapest isn't best. Compare what's included: are they removing old frames and disposal included? What warranty on frames and labour? Are seals and fixings quality, or budget stuff? A £300 quote for a window is suspicious; £400-500 is more realistic.

Checking before booking: Confirm their TrustMark or Fensa registration, ask for insurance proof, and get names of recent local jobs you can contact. A trader with nothing to hide welcomes reference checks.

Payment terms: Agree upfront. Standard is a deposit (usually 25-50%) on booking, remainder on completion. Avoid paying full amount upfront. Many traders are now offering payment plans — clarify interest rates and terms if relevant.

Contracts and guarantees: Get a proper contract — materials, start date, completion date, payment schedule, what happens if they're delayed or you're not happy. Warranties should cover frames (usually 10 years) and labour (typically 2-5 years). Read these carefully.

Eight Questions to Ask Before You Book

Use these to separate serious traders from chancers:

1. Are you TrustMark registered or Fensa/CERTASS registered? Ask for proof and verification numbers. If they're not, ask why — some are covered under a contractor's accreditation, but they should explain it clearly.

2. Can you give me three local Bridgend references I can contact? They should have recent work in the area and be happy for you to ring customers. Follow up — this matters more than online reviews.

3. What's included in your quote and what isn't? Specifically ask: removal of old frames, disposal, making good around the opening, decorating, sealing gaps. Surprises at handover are annoying and expensive.

4. How long have you been trading, and what's your process if something goes wrong? Established traders (5+ years) have systems. Ask how they handle complaints — a complaint-handling procedure shows professionalism.

5. What warranty do the frames come with, and what does your labour warranty cover? Don't accept vague answers. Get specific: 10 years on frames, 5 years on labour? What does warranty exclude? How do you claim?

6. Can you work around my schedule and how long does the job take? A single window takes 2-4 hours. A full house might be 5-7 days depending on size and complexity. Understand the timeline.

7. What happens if there's structural or rot issues once you start? On older homes this is real. How do they diagnose and charge for surprises? Who sorts remedial work — you or them?

8. Can I see samples of frame styles and colours? Reputable traders carry samples or show detailed product brochures. This isn't just marketing — it helps you visualize the finished job.
