Carl Hancock Installations in Cardiff

Terraces, bays and extensions.

A lot of Cardiff's housing is Victorian and Edwardian terraces — Canton, Pontcanna, Roath, Cathays, Splott — with bays at the front and narrow gardens at the back. Further out, Whitchurch, Rhiwbina, Llandaff and Cyncoed have interwar and post-war semis and detached houses.

At the back, the common job is a kitchen extension across the width of the terrace or into the side return. Openings are usually three to four and a half metres, which suits a three- or four-panel aluminium bifold or a two- or three-part slider. We work with your builder so the steel and the threshold are set for the door.

At the front, it is bays: replacing old timber or first-generation uPVC with frames that are properly supported, and composite doors in keeping with the street. Parts of Cardiff — including Cathedral Road and Rhiwbina Garden Village — are conservation areas, where Cardiff Council may want to see what you are proposing.

Local knowledge

What we see on Cardiff jobs.

Side-return extensions

Wide rear openings for bifolds and sliders, with the steel and floor levels agreed with your builder before the door is ordered.

Victorian bays

Two-storey bays that carry load need proper support in the new frames. We check before we price.

Conservation areas

In areas like Cathedral Road and Rhiwbina Garden Village, check with Cardiff Council first. We supply product details for any application.

Terraced access

No rear access usually means carrying frames and glass through the house. Floors are protected and the route planned in advance.

I've had all my windows and doors fitted by Carl he came highly recommended by a family member. The whole process was very easy — Carl helped me through selecting and choosing my windows and doors, him and his team were very meticulous removing and fitting the windows and doors, everything was cleaned up and spotless at end of shift. Highly recommended.

We recently had all the windows replaced at our home in Port Talbot by Carl Hancock, honestly couldn't be happier with the results. From the initial quote through to the final installation, Carl was professional, reliable and always happy to answer any of my questions or queries. The quality of the new uPVC windows are excellent — they have completely transformed the look of our home. If you're looking for a trusted fitter of uPVC windows, bifold doors or any style of double glazing, Carl is the man! Excellent workmanship, fair pricing and outstanding customer service from start to finish. A 5 star experience.

Questions

Windows & doors in Cardiff: your questions.

Do you really cover Cardiff from Port Talbot?

Yes. It is a straightforward run along the M4, and the survey is free across the city, as it is everywhere we work.

Can you fit bifolds on a side-return extension?

Yes. We check the steel and the floor levels with your builder so the threshold works, then fit the doors once the opening is ready.

Will my bay window need support?

Many Victorian bays do. We check what the frames are carrying at survey and fit bay poles or reinforcement where needed.
