Bifold Doors Morden

We design, make and fit bifold door sets for homes in Morden. This page is for owners who want to open a back room to the garden with a wide run of glass. You will learn which bifold door types suit local homes, how we fit them, what sets the cost and how to keep them running well.

Every set is made to measure from a site survey. We fit slim, thermally broken aluminium frames with A-rated glass as standard. Each job is signed off under FENSA and backed by our 10-year guarantee. For the full product range, see our main bifold doors page.

Which bifold door layouts suit homes in Morden

Most of the bifolds we fit here go into the back wall of a kitchen, a dining room or a rear extension. The right layout depends on the width of the opening and how you use the space. We set out the panels so the doors fold where you want them, not where they get in the way.

• Two or three panels: good for openings up to around three metres. Three panels often include a traffic door, so you can pop out without folding the whole set.
• Four or five panels: suits a wide extension. Odd numbers give you a traffic door plus a stack of folding leaves.
• Six panels or more: for large openings. These often split from the centre so half the doors stack each way.
• Corner sets: two runs meet at a corner with no post, so the whole corner opens up. These need a steel or beam over the top, sized by an engineer.

You also choose to fold the doors in or out. Outward folding keeps the room clear when the doors are open. Inward folding suits a narrow patio or a balcony. We will show you both on the survey drawing.

A bifold is not right for every home. If you mainly want a big view and only open the doors on warm days, sliding patio doors give you wider glass panes and fewer frame lines. We are happy to price both so you can compare.

How the frames and glass are made

Our bifolds use powder-coated aluminium with a thermal break. The break is a strip of polyamide that splits the inner and outer frame. It stops the cold outside from running through the metal into your room. That keeps the inner face warmer and cuts the risk of damp on the frame.

The glass is a 28mm sealed unit as standard. It has two panes, argon gas in the gap, a low-E coating and a warm-edge spacer. Each part has a job:

• Argon: a dense gas that slows heat loss across the gap.
• Low-E coating: a thin layer that bounces heat back into the room.
• Warm-edge spacer: keeps the edge of the glass warmer, so you see less misting around the rim.

Part L of the Building Regulations sets a limit of 1.4 W/m²K for new doors fitted into an existing home. A good aluminium bifold with A-rated glass meets this with room to spare. If you want to go further, we can fit triple glazing. It adds weight, so we size the hinges and rollers to match.

Security, seals and hardware

A bifold is a large opening in the back of your home, so we take security seriously. Every set we fit has these features:

• Multi-point locks on the traffic door and shoot bolts on the folding leaves.
• Glass fitted from the inside, so the beads cannot be removed from the garden.
• Anti-lift blocks that stop the panels being lifted off the track.
• Toughened safety glass, with laminated glass as an option for extra strength and less noise.

Seals matter as much as locks. We use gaskets all round each panel and a drained sill that sends water back out. Stainless steel rollers carry the weight, so the doors glide when you fold them. We match the roller and hinge rating to the real weight of each panel, with a margin to spare.

Fitting bifolds in Morden homes

Most bifold jobs here start with a new or wider opening in a back wall. That means a new lintel or beam to carry the wall above. We check the structure on the survey. If a beam is needed, we tell you up front and explain who will design it.

On the day, we take out the old doors or window, prepare the opening and fix the outer frame. We pack it level and square, because a bifold that is out by a few millimetres will not fold well. Then we hang the panels, set the locks and seal the frame inside and out. Most sets are fitted in one or two days.

Access is a big part of planning the day. Long frames and heavy glass need a clear route to the back of the house. If you have a side gate, we use that. If not, we plan the route through the house and protect your floors. The note on parking above tells you what to expect on your road.

Our full process, from survey to aftercare, is set out on our how we work page. It covers each stage in turn, so you know what happens and when.

What drives the cost of a bifold door

We do not publish fixed prices, because no two openings are the same. Each job gets a written, fixed quote after a free survey. You can ask for your quote here. These are the main things that set the price:

• Size and panel count: more panels mean more frame, hinges and locks.
• Glass: triple glazing, laminated glass or solar control glass all add to the cost.
• Colour: a single standard colour costs less than a dual colour or a special finish.
• Threshold: a low, flush threshold needs more prep at floor level.
• Building work: a new opening, a beam or making good to brick and plaster.
• Extras: blinds inside the glass, trickle vents or upgraded handles.

Your quote lists each part, so you can see where the money goes. It also sets out the payment stages in writing.

Looking after your bifold doors

Aluminium bifolds need little care, but a few simple jobs keep them running well for years.

• Wash the frames with warm, soapy water a few times a year.
• Brush or vacuum grit from the bottom track every month or so.
• Keep the drain holes in the sill clear of leaves.
• Put a drop of light oil on the hinges and locks once a year.
• Check the seals and call us if one is torn or lifting.

If a door starts to drag, do not force it. A small adjustment to the rollers usually puts it right, and we can do this on a service visit.

Choosing the right option for your home

Start with how you will use the room. If you want to open the whole back wall in summer, a bifold is a great choice. If you want the view most of the year and only open now and then, a slider may suit you better. Think about where the open doors will stack and make sure they will not block a path or a seat.

Next, think about the light and the aspect. A south or west facing wall gets a lot of sun, so solar control glass can keep the room cool. A shaded wall may gain more from triple glazing. We will talk this through on the survey and give you a clear view of the options.

Frequently Asked Questions

Can bifold doors be fitted on an upstairs balcony?

Yes, as long as the structure can take the load. We check the opening and the balcony on the survey. If needed, a structural engineer confirms the beam and the floor can carry the doors. We then make sure the set meets wind load, drainage and guarding rules. Inward folding doors often work best on a balcony, as they leave the deck clear.

Do bifold doors add value to a home?

Buyers like a bright, open room that leads straight to the garden. A well made set with A-rated glass, good locks and a clean finish helps a home stand out. Keep your FENSA certificate and your 10-year guarantee papers safe. A buyer's solicitor will ask for them, and having them to hand makes the sale go more smoothly.

Can you choose a colour other than white or grey?

Yes. Aluminium frames are powder coated, so we can match almost any RAL colour. You can pick a matt, satin or textured finish. Dual colour is also an option, with one colour outside and another inside. We will show you samples before you order, and your quote will confirm the exact colour code so it can be matched later.

Can blinds be fitted inside the glass?

Yes. We can fit sealed units with blinds built in between the panes. They stay clean and do not get in the way when you fold the doors. You work them with a small magnet slider or a motor. They add some cost and lead time, so we list them as a separate line on your quote.

Do bifold doors need special cleaning products?

No. Warm water with a little mild washing-up liquid and a soft cloth is all you need. Avoid scourers, bleach and strong solvents, as they can mark the powder coat. Keep the bottom track free of grit and oil the hinges once a year. That simple care keeps the doors running well and within the terms of your guarantee.
