Double Garage Door Conversion
Discussion
It’s been a while since we had one of these threads, just wanted to get opinions on whether this is good value as i’ve just had a quote to convert my double garage doors into a single door.
This is the current garage with two up and over doors. It has full power and lighting.
Above each door is an existing RSJ, they meet on the central pillar but are not joined. I understand they need to be removed and replaced with a new RSJ of just over 5m, as they can’t be joined. The width of the door opening would be 5.01m, and i’ve been quoted on a SWS sectional door (non-ribbed) with a Hormann remote control door opener.
Total quote has come in at £7k, and that includes a discount on the door of £870. I was expecting something under £4k to be honest, and having just moved in and with a number of competing priorities this will get dumped to the back of the queue, which is frustrating.
There’s no breakdown of the costs so unclear where the biggest chunk of that is, i assume the RSJ?
Obviously i’ll call them tomorrow and ask, and maybe the two existing 2.4m RSJs have a scrap value, but nonetheless I was surprised that this job is so pricey. Maybe it’s South East prices.

The RSK isn’t the biggest chunk, the garage door fitted is circa 4.5k-5k at todays prices. So it’s 2-2.5k for a skip, builders time and the rsj.This is the current garage with two up and over doors. It has full power and lighting.

What's going on the skip?I'm sure someone will take two garage doors, two RSJ and a few bricks for free off market place/gumtree!

That was my initial assumption on what could be done. There is a 2-3mm gap between the existing RSJs and I did ask the guy if connecting them would be possible to minimise work, bracing etc. and he said no as you couldn't guarantee the strength of the weld and it wouldn't meet regs.I'm going to get a second mob round and see what's what, I certainly think this is £2k or so over what is normal, but if they both come back with the same price then it is what it is and I'll put this job on the back-burner.
Jefferson, very similar garage setup to you and I'd like a single door conversion too.
I'm not surprised at the cost - everything is many multiples higher than I would estimate - but nevertheless that does seem a lot of money @ c. 6k before VAT.
I suppose: cost of door + automation (2k?), cost of new steel and delivery (1k?), cost of disposal (0.5k?), cost of labour to do the job (a day? 0.5k) + overheads (0.5k) + profit (0.5k?).
I've found trying to understand costings fruitless. If someone wants to charge £x then I just decide whether I want to/can charge £x. Stings though.

They get proper engineers to design each element without reference to span tables or any other short-cuts. In this case a bespoke, insurance backed solution with the evidence to satisfy Building Control is likely to be a similar cost to just putting a bigger beam in, because it's outside the norm of what a residential engineer would normally design.
Welding the beams isn't the right approach, it would be difficult to do it in-situ, would need a suitably coded welder (ie expensive) to satisfy the engineer and would be inferior to plates bolts between the webs. Joining the beams isn't going to allow it to take any vertical load, only stop the beams spreading as they collapse, if the weld holds it won't collapse, but it'll sag too much. A plated solution will allow that spread-resistance to be done in a far more controlled manor.
Given the load resistance is largely generated by the height and thickness of the steel web, it should be possible to design a solution that uses plates to increase that stiffness sufficiently given the loading is relatively low. But that route requires a bespoke design and a non-standard install, including drilling lots of holes in the beam as you go.
If you had a tame engineer and could DIY it you might save some money, but as soon as you start paying professionals it'll be cheaper to go with a bigger beam I suspect.
Door & Automation list price for a 5,182mm width door is approx £3k plus vat depending on style and colour chosen.
6m length Universal beam is approx £105 plus vat
Plus disposal of old door (this has a small scrap value if metal) plus disposal of central pier spoil. Plus making good of brickwork - materials (some bricks may be able to be reused) & brickie labour plus trims to opening. Plus installation of door 2x man job, relocation of power supply by qualified electrician and configuration of the operator. It all adds up and the originally quoted price seems not unreasonable to me.

I write to announce a September price increase and to update you on our proposition to the garage door trade. First to our price increase. Cost pressures on materials, energy and transport have been sustained. Whilst we’ve absorbed much and delayed implementation as long as possible, regrettably, we must raise prices
Effective from September 1st, 2022. The increase is 5% across all products.
This will be the third price increase on garage doors this year so far.

Bit of a thread resurrection but I'm thinking a big single door is the inevitable way forward for my 2 singles as cars are just getting wider and wider, current 2 cars just fit, and my next possible car 'just' fits, dealer brought one round last night and it went in, but you had to hold your breath, so I think the sensible option is get the door changed.
I can find plenty of companies to sell/fit me a garage door, and I'd imagine any competent builder can fit the steels and knock down the pillar, but would prefer a one hit solution so no one can blame the other for any issues, one person to deal with for the whole gig, any pointers?

Some of the sectional doors fit on the rear of the brickwork which looks like it’d give you another 6-8” width.
But then I'd loose about 8" in depth, and I can't afford to loose any length 
longest time yet to reply to a message
But just had a quote for the work and the longer I leave this the more expensive it's getting....£7.4k for a roller door or £8.2k for a sectional door fitted.
I'd prefer the Roller, and not just for the cost saving, but I'm not sure it'd fit, and again I don't want it fitting behind the brick opening.
