Service overview

The bi-fold service — measured, made, fitted

A bi-fold door install is a substantial structural fit. We survey the aperture (including any structural opening work required), specify the correct system for the width and traffic loading, manufacture the door set to millimetre-accurate dimensions, and install it with the precision it needs to slide sweet and lock true.

The right client is anyone connecting a kitchen, dining space or garden room to an outdoor area — usually a rear extension, a kitchen remodel, or the ground floor of a new build. Bi-folds are the reason many of our clients call us in the first place.

You need a proper installer because a bi-fold that isn't dead level, correctly tracked and properly adjusted becomes a daily source of frustration. Rollers wear out, gaskets misalign, and the door 'catches' at every fold. Get the install right first time and it just works.

The cost of leaving it

The bi-fold problems we're regularly called in to fix

Bi-folds installed by generalists rather than specialists start showing the same set of problems within a couple of years.

Doors that drag or stick

Frame not perfectly level → weight bears on the tracks unevenly → rollers wear prematurely → door drags. Every fold becomes work.

Water ingress at the threshold

Threshold and drainage detail is the number-one weak spot on bi-folds. Done wrong, water pools inside the track after every storm.

Gaskets that don't seal

Mis-adjusted door leaves and worn gaskets mean the door 'closes' but doesn't seal — you get draughts, noise and heat loss with the doors fully shut.

Locking that gradually fails

The end lock is under constant load. Poor system choice or wrong hardware and the door won't lock cleanly within 18 months.

Our process

Five steps from enquiry to guaranteed install.

  1. STEP 01

    Free specification survey

    We visit, measure the aperture, discuss configuration (fold-in / fold-out, split configuration, traffic door position), colour and glazing spec.

  2. STEP 02

    Written quote in 1–2 days

    Itemised by system, configuration and glazing. Valid 30 days — and honoured beyond if supplier pricing hasn't moved.

  3. STEP 03

    Order & manufacture

    50% deposit secures the slot. Manufactured to survey dimensions in your specified RAL colour. 4–6 week lead time.

  4. STEP 04

    Precision installation

    Structural opening prepared and levelled, threshold bedded correctly, frame and door leaves fitted, tracks adjusted, sealed and demonstrated with you present.

  5. STEP 05

    Handover, notified, guaranteed

    ASSURE-notified, 10-year frame and finish guarantee, 5-year glass guarantee, IBG cover — plus adjustment aftercare if anything moves in the first 12 months.

Benefits

Concrete outcomes — not vague promises.

Configurations from 2-pane up to 7-pane sets — genuinely open the room to the garden on summer days.

Correctly fitted systems from Smart, Aluk and Jack slide smoothly for decades — not weeks.

Slim sightlines, maximum glass

Aluminium bi-folds show more glass and less frame than any other opening system.

Multi-point locking on the master door and shootbolts on every leaf. High-security cylinders as standard.

Weather-rated

Modern thresholds and drainage channels are engineered for driven rain — including South Wales winter weather.

10-year cover with IBG

Frame, finish and hardware covered — plus the guarantee is independently underwritten.

In detail

Systems, configurations and glazing in detail

Bi-fold specification is more than 'how many panels'. Configuration, threshold, colour and glazing are all decisions we walk you through at survey.

Systems

Smart Visofold, Aluk BSF70 range and Jack Aluminium bi-fold suites — the systems trusted on the majority of UK bi-fold installs, each with slightly different sightlines and hardware options.

Configuration

Fold-in or fold-out; even split, offset split, or a traffic door with the rest folding beside it. Configuration is chosen for how you actually use the room.

Thresholds

Weathered thresholds for maximum weather resistance, low thresholds for flush interior/exterior levels, and rebated thresholds for wheelchair access.

Finishes

Any RAL colour, powder-coated inside and out. Dual-colour available.

Glazing

Argon-filled Low-E double glazing as standard, with solar-control coatings for south-facing installs and acoustic laminate options for busy roads.

Residential vs commercial

Bi-folds work brilliantly in restaurants, cafés and commercial break-out spaces — we specify commercial-suite hardware where traffic loading justifies it.

Frequently asked

Everything homeowners ask before booking.

How much does an aluminium bi-fold cost?

There isn't an honest 'from' figure — cost depends on width, number of panels, colour, glazing and threshold detail. Fixed itemised quote after a free on-site survey.

How long from order to installation?

4–6 weeks from receipt of your 50% deposit for manufacture, plus one to two days on site to install.

Do I need structural work to fit a bi-fold?

Sometimes — replacing existing patio doors is usually straightforward, but opening a new wall aperture involves a steel or lintel. We flag structural requirements at survey and coordinate with your builder or structural engineer.

Are bi-folds secure?

Yes — multi-point locking on the master door, shootbolts on every folding leaf, anti-snap cylinders and PAS 24-rated systems available where security is a priority.

Which is better — bi-fold or sliding?

Bi-folds fully open the aperture; sliders offer larger uninterrupted glass panels when closed. It's a lifestyle decision — we'll talk you through both at survey.

How thermally efficient are they?

Modern aluminium bi-folds with polyamide thermal breaks and argon-filled Low-E glazing perform well within Building Regs — a world away from older aluminium systems.

Do they leak in heavy rain?

Not when installed correctly. Threshold bedding, drainage channels and gasket alignment are exactly what our team is trained to get right.

What guarantee do I get?

10 years on the frame and powder-coat finish, 5 years on the sealed glass units, IBG-backed for independent protection.

Do you fit bi-folds in Newport?

Yes — Newport, Blackwood, Caerphilly, Cwmbran, Pontypool, Ebbw Vale and across the Gwent valleys.

Do you adjust the doors after install if they need it?

Yes — post-install adjustment within the first 12 months is included. Modern bi-folds settle slightly, and a small tweak keeps them running perfectly.
