Ely, Littleport and the villages along the A10, worked from our unit at Oak Lane Business Park. Part of our replacement doors work.
We get a fair few calls about new bi-fold doors around Ely when a repair would sort the problem. We’d sooner tell you that on the phone than after you’ve paid for a new set.
Most of what we get called out to on bi-folds comes down to the running gear. A door that sticks or drags has usually got a worn roller, or grit sat in the bottom track. Around Ely and Littleport the ground moves a fair bit, because Fen peat shrinks as it dries out, and a couple of millimetres is enough to put a panel out of line. Adjusting the rollers and squaring the panels up normally has it running smoothly again.
Misted glass in one panel is the other common one. The seal in the unit has gone and let moisture in. We take that unit out, fit a new one, and the frame stays exactly where it is. That comes to a fraction of a full set of doors.
Handles, locks and hinges are parts, and parts can be changed. Most repairs are sorted the same week.
Some jobs are past repairing. If the aluminium frame has corroded or twisted, or the threshold has cracked, there isn’t much left to fix. Same if you can feel cold air coming through with everything shut on a still day, because that usually means the frame has dropped or the seals have gone all the way round.
The other one that catches people is parts. Older systems get discontinued, and once the gear for a door is out of production we can’t get hold of it. At that point a new set with a guarantee behind it works out better than trying to source a part that’s no longer made.
And if you’re taking a wall out or widening the opening as part of an extension, you’re ordering new doors anyway. That’s the point to get the size and the spec right.
If you’re not sure which of those you’re looking at, send a photo over on WhatsApp and Dan will tell you what he reckons. He’ll come and have a proper look if it needs one. If a repair will do the job, that’s what he’ll say.
Aluminium goes on most of the bi-fold doors we fit around Ely and Littleport. Which one suits you comes down to the width of the opening and how much frame you want to see.
Aluminium is strong enough to be drawn into a slim frame, so you get more glass in the same opening and more light with it. It’s also stiff enough to carry a four or five panel run without going out of true. Past about three metres we’d steer you towards aluminium.
uPVC costs less and works well on smaller openings. The profiles are deeper, and they carry steel reinforcement inside to keep them rigid. On a two or three panel set that extra depth barely shows, and you’d struggle to fault them.
Colour is worth settling early, because the frames are powder-coated at the factory. Anthracite grey is what most people go for, with matt black behind it. You can pick anything from the RAL range and have a different colour inside and out, so grey facing the garden with white facing the room is a common one. The powder coat holds its colour and won’t need painting. uPVC comes in fewer colours.
Before anything gets ordered, Dan comes out to survey the opening and we settle three things: how the panels split, what glass goes in them, and which threshold sits under the doors.
A three panel set folds to one side and stacks against the wall. A five panel run gives you a wider clear opening, though the stack takes up more room when it’s folded back. Configuration is the bit people forget. Most sets can be split so one panel works on its own as a normal door, which saves folding the whole lot back every time you want to step out to the garden.
Double glazed units come as standard on aluminium bi-folds. Triple glazing costs more and keeps more heat in, which is worth pricing up if you’re extending a home in Ely or Littleport and the opening faces north or east.
Building Regulations require safety glazing in doors, so that part isn’t optional. In practice that means toughened glass. After that it comes down to coatings. Low-emissivity glass reflects heat back into the room, and solar control glass takes the edge off a south-facing opening so the space doesn’t cook every August.
A low threshold sits almost flush, which looks cleaner and makes it easier to get a wheelchair or a pushchair over. A weathered threshold sits higher and does a better job keeping driving rain out, though the track can often be recessed into the floor to bring the step right down. If yours faces straight into the weather we’ll tell you what we’d do, and either way we check the drainage and the ground level outside so water doesn’t sit against the frame.
A standard white three panel bi-fold in Ely, supplied and fitted, starts from £3,600 including VAT. Colour is the first thing that moves it, since any RAL shade or dual-colour finish adds to the white starting price. Panel count comes next, so a two panel set sits below that figure and a five or six panel run sits above it.
After that it’s the width of the opening, the threshold and the glass spec. Hardware makes a difference as well, mainly the locking system and the handles. Triple glazing puts it up another step.
Wind loading catches people out around Ely and Littleport. The Fens are flat and exposed, with nothing much to break the wind, and on a wide span of four or five panels the structural calculations can call for thicker aluminium profiles or upgraded glass to carry the load. That’s a Building Regulations requirement. Dan will run you through the calculation at the survey so you can see where the money goes.
Ask any quote what’s included. Does it cover the threshold and the cill? Does it cover making good the plaster inside and the brickwork outside once the doors are in? Some quotes are supply only. Others cover supply and fit and leave the finishing to somebody else.
Send us a photo and we’ll give you a ballpark to work with. For a firm price the opening has to be measured, the lintel checked and the floor level confirmed, so that means a proper survey first.
On a newer build the openings come in standard sizes and the lintel is already rated for the span. Fitting an aluminium bi-fold into that is close to a textbook. A 1960s semi in Littleport takes a longer look before anything gets ordered.
Plenty of houses in Ely have solid brick walls, or an early cavity build that was never meant to carry a wide glazed opening. At the survey we look at what’s holding up the wall above the opening, and whether the existing lintel covers the width you want. We check what the frame fixes back to as well. That isn’t always obvious until the plaster comes off.
In an older house the floor across a wide opening is rarely dead level. The threshold still has to sit level, or the panels won’t fold and run properly, so we pack and set it on the day.
Access is worth a thought on the older places. Bi-fold panels and the glass are heavy and awkward, so we check the route in from the road before the delivery date. A side gate or a narrow passage can change how the day runs.

It runs the same way as any of the windows and doors we fit around Ely. Send a picture of the opening over on WhatsApp and we’ll come back with a rough figure, usually the same day or the next. No visit needed for that part. If the ballpark suits you, Dan comes out and measures the opening properly, and there’s no charge for the survey or the quote.
Nothing gets ordered until the survey’s done, because the bi-folds are made to your opening rather than pulled off a shelf. It’s 50% on order and the other 50% once the job’s finished.
Dan fits the doors himself, and a trusted installer works alongside him on the bigger runs. He takes his time getting the panels running sweetly. Then the installation gets registered with Assure, and your certificate usually follows inside a month. Anything needs adjusting after that, you ring the same number you rang at the start.
The choice usually comes down to how wide the opening is and how much wall you’ve got either side of it. We go through it on nearly every extension we quote around Ely.
Bi-fold doors, sometimes sold as folding patio doors, fold back on a track and stack flat at one end. That gives you the widest clear opening of the three, so the kitchen and the garden feel like one space on a summer afternoon. The stack has to go somewhere, though, so you need a run of the wall beside it.
Sliding patio doors run one panel behind the other, so there’s no stack to find room for. That makes them easier fit on a tighter run. One panel does sit in the opening at all times, so you never get the full width clear. They’re simpler to use day to day as well, one panel and a handle. Plenty of people come to us set on bi-folds and go for sliders once we’ve measured up.
French doors swing open on hinges. Two panels at standard door width, and no track along the bottom to keep clean. They suit a smaller opening, or a spot where an old back door is coming out.
If your opening is on the narrow side, Dan will say so at the survey and point you at sliders or French doors. Give us a call and talk us through what you’ve got.
Questions People Ask
We can usually get a survey booked within a few days around Ely. Dan visits your property, measures the opening properly, and checks things like wind loading before anything gets ordered. A wide opening needs the right frame strength from the start. Booking early also gives you time to think through glazing and threshold choices without rushing a decision you’ll live with for years.
Dan measures your opening, checks the wall and floor levels, and talks you through options like panel count, glazing, and threshold type. If your home sits on peat or clay, which is common around Ely and Littleport, we’ll also check how the ground has settled, since that affects how the frame sits. You’ll walk away with a clear plan, not a sales pitch. If a repair would sort your existing doors instead, we’ll say so at this stage, not after you’ve ordered a new set.
It usually comes down to the ground, not the doors. Ely and Littleport sit on Fen peat and clay, and that ground shrinks and shifts more than most people expect, especially after dry spells. This movement can knock a bi-fold panel slightly out of alignment, causing sticking or dragging along the track. A proper adjustment of the rollers or track almost always fixes this. It’s rarely a sign the doors need replacing, so it’s worth getting checked before assuming the worst.
Aluminium, for most openings around Ely. It holds its shape across a wider span, which is what bi-folds are for in the first place. uPVC costs less and is fine on a two or three panel opening, but the frames are chunkier and can flex on a longer run. If you’re weighing up cost against sightline, that’s a conversation for the survey rather than a website.
Not always, but it’s worth considering if your opening faces north or east. Double glazing comes standard and does a solid job for most homes. Triple glazing cuts heat loss further, which makes a real difference through a Fen winter, especially on a wide opening that catches cold wind off flat, open land. If you’re planning to use the room year-round, it’s worth pricing both and deciding at the survey.
A standard white three panel bi-fold in Ely, supplied and fitted, starts from £3,600 including VAT. Colour is the biggest thing that moves it from there, and panel count comes next, so a five or six panel run costs more than a three panel set. Send a photo over on WhatsApp and we’ll give you a ballpark, then a firm price once we’ve surveyed the opening.
No. It’s 50% when you place the order and the other 50% when the job’s finished and you’re happy with it. The deposit covers the doors being made to your survey measurements, because they’re built for your opening rather than pulled off a shelf.
