Cost of new conservatory

Wizwoo

OK - anybody just had a new conservatory? Or are there any builders out there that can give me a minimum kind of guide price for what I want doing?

We really need to replace ours since the wood has started to rot "really" badly in places and the roof leaks. We just want to knock this one down and replace with the same kind of thing (in terms of size etc)

Size = 11ft x 5 ft

What we were hoping is that since my OHs brother is a glazier that we should be able to get the glass / roof from them at cost plus a bit and then a builder to do the rest.

Any ideas anyone in terms of what we need to think of as a minimum?

Any one with any idea?
I've looked on the net and all the conservatories are bigger than ours so the info isn't really relevant, plus they don't include the cost of actually putting it up.

It's a lean to conservatory and will hopefully have a dwarf wall and be uPVC. Anyone had one done lately?
Thanks,

My Fil and I put ours up about 10 years ago. it cost me a total of around £3200 to buy it and have the base built. that included having the soloid floor laid, which was done after the conservatory was assembled

Now I am in the trade I would build the base myself. Putting it up was easy. It was a Wickes type conservatory (actually the same manufacturer that supplied the Great Mills stores at the time) butwe bought it via another retailer who beat their price.

It took 2 of us 4 days to put up. The instructions were really easy to follow - we read them through several times before we started.

The only problem with your conservatory is that replacing it with a standard off the peg job would involve rebuilding the base. My guess is that you should allow around £1200 or so in todays prices to get this redone to the size you would require. The cost of the UPVC kits haven't really gone up that much. If you want a dwarv wall allow more for the base and less for the UPVC kit.

To get the whole lot done by someone else you're probably looking at around the £8K mark or more dependong on a whole list of factors from where you are in the country to the type of site you have.

If you need to demolish yours then the process would be as follows:

1 - Demolition. this could be a DIY job if done carefully and safely. get a 4 or 6 yard skip that you can just chuck all the glass and wood in. You'll also need this for the base. When removing the glass use wide masking tape and do a WWII style cross on each pane both sides to minimise flying glass and make sure you've got plenty of strong disposable dust sheets to catch that that does fly.

2 - Ground preparation. Again this is labour intensive but not skilled. You'll need to dig up some of the old base to allow for the new base including the floor to be laid properly. Your builder would be able to advise you on that if you have him do the erection. Some or all of the rubble may be needed for hardcore for the new base, so don't go chucking it all yet! Trenches will need to be dug for the new base, depending on how this is being laid.

3 - Preparation of the new base. This may be done any number of ways. Typically with a virgin site the approach is to dig 450mm deep trenches to take the outside walls, lay the concrete in these and then build the walls. The concrete sub base is laid on membrand over insulation onto the sub base - usually blinded earth. The final screed is best laid when the conservatory is erected and waterproofed.

4 - Construction of base. The walls are built up to the right dimensions for your conservatory, leaving gaps for doors etc.

5 - Erection of conservatory. This is relitively straight forward. The kits are usually supplied as panels that lock together. The one I fitted used a modular design so a number of standard panels were supplied for my chosen model. A larger conservatory would have meant more panels and a smaller one would have meant fewer. Designs vary but mine used a cill that, after being fitted, was designed to allow the panels to click into place. The panels were then held into place using angle brackets securing them to the cill at the ends. The panels were secured onto the existing house wall with special wall profiles designed to accomodate less than vertical house walls.

The last panel to go into place was that comprising the french doors. Once this was in place then it was time to start the roof. This consisted of a retaining bar against the house that held a number of rafters in place. These were then secured onto the frame to take the gable ends, other bits and eventually the roofing sheets.

Eventually finishing jobs such as guttering and lead flashing etc finish the job.

Finally the final floor screed is laid

Thanks loads HugoSP - just the kind of info I needed.
To be honest my OH and his brother will probably do the uPVC bits but we'll need to get a builder in to so the base and the dwarf wall and then the finishing touches (guttering and flooring).

Money is really tight but it really needs doing and I don't want to do half a job so really wanted to get a rough idea of cost before I waste a builders time to come round and give us some quotes.

The demolition bit sounds alright too - my favourite part of any job :rotfl:

This is where we got ours last year, they will make to your sizes as we had to have one made to different size to the ones on the website.


The price of the conseratory was £2300 for 2.4m wide x 3.2m , with double french doors, 4 opening windows and roof vent,moulded panels to floor and delivery , it also included drain pipes, sealant, fixings and instructions, the fixings that came with it wernt very good acording to the builder so he used some different ones (self tapping into concrete lastest thing apparently ), but he did mention the conservatory was of good quality

Heres a pic if you are intrested

Wizwoo

Thanks denos, looks great - what does the £2300 include? Does it include the builder's charges for putting it up?

deanos

£2300 was the price of the conservatory and the extras, double french doors, roof vent, 4 opening windows & panels to the floor & delivery, it also included all the fixings, drainage & fixings/screws etc.

We got a local guy to put it up i was going to do it myself but had injured my arm so that knackered that idea up and the wife was nagging to get it put up , it cost £500 (cash in hand )but that included the flashing as well which would have cost £150 , it took 2 men , 2 days to put it up.

Anyone done one where everything was included from start to finish? Making the base, tiling, putting up the whole lot etc?

Any good websites?

Want to get it done but one company needs to do it all as hubby unable to help due to disability.

Dont know where you live but James Oliver does complete packages

That was a VERY good price to put it up!

Did he use lead flashing or flashband on the roof? Either is OK but lead flashing will mean 40 years before problems arise, Flashband may not last the course. We put the flashband up THEN lead flashing covering it.

deanos

It was proper lead flashing i wouldnt touch that flashand stuff

If you look in the picture it was done in a straight line not stepped, this would have added an extra £100 or so in labour but it still looks fine
