How we work
Every opening is different. So every job starts on site.
We measure the structural opening ourselves and spec the frame to suit it — threshold levels, trickle vents, glazing and finish all agreed before anything is ordered. The same team takes it from that first survey through to installation and aftercare.
Our speciality
Aluminium Bifold & Sliding Door Specialists
Large-format aluminium glazing for extensions, renovations and contemporary homes across South Wales.
Aluminium is what lets an opening get genuinely wide. The frames are slim enough to disappear against the glass, strong enough to carry a six-panel run without sagging, and thermally broken so the room behind them stays warm. We survey the structural opening, agree the threshold level before anything is ordered, and set the track dead level so the panels stack and glide with one hand years later.
- Bifolds — two to seven panels, stacking left, right or split
- Inline sliding doors — ideal where folding doors would encroach on your space, while delivering dramatically slimmer sightlines and expansive, uninterrupted views
- Low thresholds — flush and fully weathered options for a seamless finish and essential weather protection
- Colours and finishes — anthracite grey, black, white, any RAL colour or dual-colour powder-coated finishes
Also in aluminium: windows · front doors · internal steel-look screens

Fully insured
Public liability cover is in place before anything is cut out of your wall, and every fitting day is worked to it. Certificates available on request, before you commit to anything.
Building Regs compliant
Thermal performance, trickle ventilation, safety glazing in critical locations and means of escape from first-floor bedrooms — designed in at survey, not discovered afterwards.
The quote is the price
Written down and held — unless you change the specification. No day-rate creep, no discovered extras on the last afternoon, no deposit taken before you have the figure in hand.
Led personally
Carl leads every job personally, from survey to final fit — so the person who priced the work stays answerable for it. You are never routed through a call centre or handed to a crew nobody introduced you to.
Made good, cleared away
Reveals made good, sills sealed and the silicone cut clean. Old frames, spent units, packaging and offcuts all leave on the same van they arrived in.

What we install
What we fit, and how we fit it.
Whether it is one tired front door or a full house of frames, the job runs the same way: survey it properly, order the right product for the opening, and fit it so it still shuts sweetly in ten winters' time.

Before & after · Porch replacement
Same footprint. Entirely different room.
Drag the handle to compare.
A rotten lean-to, replaced with a porch built to last.
The original timber lean-to had rotted at the base, with soft posts, a split corrugated roof and single-glazed sashes that had stopped sealing years earlier. It was removed and replaced with a fully framed uPVC porch on a level base, insulated Hollowclad dwarf walls, a glazed upper section on two sides, a properly guttered roof falling to a downpipe, and an outward-opening door with an obscure panel. The wall behind it is now dry for the first time in years.

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.

About Carl Hancock Installations
Built on generations of experience.
Carl Hancock Installations is a family-run business led by Carl, working alongside his father, Andrew. Andrew has worked in the trade since leaving school, bringing more than 40 years of experience to every installation.
Carl brings 20 years of industry experience, having started alongside his dad at 16. He learned the fundamentals of the trade properly — from carefully removing old frames to installing, glazing and finishing every job to a high standard. He spent his early years working on residential properties, fitting uPVC windows and doors, roofline products and conservatories.
He then progressed into aluminium fabrication and installation, working on aluminium windows and doors, commercial shopfronts and curtain walling systems. A spell in Hertfordshire installing large aluminium sliding and bifold doors further broadened his knowledge and developed the specialist skills he brings to the business today.
Carl founded Carl Hancock Installations to put quality firmly within his own control. Carl and Andrew take genuine pride in every installation, combining careful workmanship and meticulous finishing with only tried-and-tested, industry-leading products.
Every project is completed with the same attention to detail and commitment to getting the job right — giving customers lasting quality from a trusted local family team.
