Warmer homes, lower bills, and kerb appeal that lasts.
If your windows and doors are draughty, dated, or driving up your energy bills, it’s time for a change. At Adfer Cymru, we supply and fit secure, energy-efficient uPVC and composite doors, alongside modern double and triple-glazed windows — finished to perfection inside and out.
Energy-efficient comfort
Replacing old timber or worn-out units with new, high-performance windows and doors makes a visible difference to your home’s comfort and running costs. Our installations improve insulation, reduce noise, and boost your property’s EPC rating — a big win for both homeowners and landlords.
Affordable style, built to last
Most of our customers choose crisp, clean white PVCu for a modern, low-maintenance look, but if you’d like something more bespoke, we offer a range of colours, finishes, and composite doors that combine durability with standout style. Whatever your budget, you’ll get windows and doors that look great and last for years.
Finished properly
Where others might leave rough edges, we believe in doing the job right. Every installation includes new window boards if needed, and freshly plastered reveals for a neat, polished finish. That means no chasing other trades — just one point of contact, and results you’ll be proud of.
We can also undertake other renovation work in your home at the same time, so if you’re sick of that textured ceiling or dated fireplace, we can transform these too.
Flexible for Every Client
Whether you’re a homeowner wanting kerb appeal, a landlord improving EPC ratings, or a higher-end customer after composites, we can tailor the perfect solution to you.
Secure by Design
Security matters. All our doors and windows meet modern standards, with multipoint locking systems and options that comply with Secure by Design for extra peace of mind.
Honest Advice, No Hard Sell
We won’t push unnecessary extras. Our reputation rests on honesty, quality, and practical solutions that stand the test of time.
The hassle-free choice
Whether you’re upgrading your family home or managing a rental portfolio, we handle the whole process — from survey and advice through to fitting and finishing. With Adfer Cymru, you get honest advice, tidy work, and attention to detail every step of the way.

Frequently Asked Questions
Will replacing my windows and doors really make a difference to my energy bills?
How do new windows and doors affect my home’s EPC rating?
Upgraded windows and doors improve energy efficiency, often moving a property up a band on its EPC certificate. This is particularly important for landlords, as minimum EPC standards apply to rental homes.
Do you finish the inside as well as the outside?
Absolutely. Unlike many fitters, we don’t leave rough edges. We replaster reveals and install new trims and window boards where needed, giving you a neat, clean finish straight away.
What options are available beyond plain white uPVC?
While white uPVC is the most popular, you can choose from a wide range of colours, woodgrain finishes, glazing designs, and hardware styles. These can help your property stand out or blend with period features.
Are composite doors worth the extra money compared to uPVC?
Composite doors are more robust, offer superior thermal performance, and have a premium look. However, modern uPVC doors also perform very well and remain the most popular choice for affordability. We’ll help you weigh up the pros and cons based on your budget and needs.
How secure are your doors and windows?
Do you handle planning permission for window replacements?
How long does it take to install new windows and doors?
A standard house can usually be completed in 1–3 days depending on the number of units. We’ll agree a clear schedule before starting, minimising disruption to your household or tenants.
What maintenance is required after installation?
Modern PVCu and composite doors are virtually maintenance-free. Frames and glass just need regular cleaning, and hinges or locks benefit from occasional lubrication. No painting or staining is needed.
Why choose Adfer Cymru instead of a national chain?
With us, you get personal service, meticulous attention to detail, and a complete finish — no rushed jobs, no hard selling, and no corners cut. You’ll have one trusted point of contact and work completed as if it were our own home.
