Hi All My single story extension is ready for first fix wiring. I am extending the ground floor ring main into the new room to supply the sockets however its going to be difficult to access the lighting circuit of the original house in order to extend it without ripping flooring up in various...

Hi All, I am preparing my concrete base for liquid screed over 100mm PIR insulation. 2 questions... 1) The boards will be taped however they move up and down when walking across them. Whats the best way to secure them down? 2) The perimeter of the room is lined with 25mm insulation to protect...

Hi all What fixings would you recommend for securing aluminium bifold doors to H&H 3.6n blocks? Are they too soft for regular concrete screws or would you suggest using Fischer frame fixings instead? Cheers

Hi All Is it a problem to apply the top coat to a fibreglass flat roof 8-10 days after application of the resin/matt layer? What do you think? Thanks

Hi all. My extension parapet flat roof with roof lantern is almost ready to be fibreglassed (over 18mm osb). I have bought wall fillet trims to lap the fibreglass up onto the existing house wall and I was going to reinforce the roof lantern and parapet corners with an extra layer of glass matt...

Thanks for the replies. I must say it does make me a little nervous! What would you say a reasonable price should be for this amount of screed supplied and pumped by a company?

But it would be a flowing liquid? is it any different to someone mixing up their own self levelling floor screed which is done all the time by Diyers...:unsure:

Hi All After getting a £1250 quote for 18m2 of floor screed at 50mm, I thought I would investigate other options. I will require liquid screed for my extension with underfloor heating. I cannot go for a dry screed as I only have 50mm to work with. Has anyone ever DIY'ed liquid floor screed? I...

Thanks Stuart. Good to know. For peace of mind and to keep BC happy, I will bite the bullet and will use Helical ties. Is a pilot hole still needed in the timber?

About 7. :) I can only see them sold in packs of 100 and then a 50 quid tool is required for the drill. Also, can helical ties go Into timber? I figured 150mm screws and a squirt of resin would be just as good...

Thanks noseall. BC approved my plans inadvance. 130mm insulation within the timber leaf and 25mm outside it. Then 50mm empty ventilated cavity. What if Installed the screws at an angle so con densation can run off? This should act the same as a wall tie...no? Cheers

Hi all I did not realise wall ties need to be in place on every course around doors. My extension consists of timber inner leaf, 50mm cavity and blockwork external. As a cheaper alternative to helical wall ties, I was considering drilling a hole in the masonry, squirting some kemfix in and...

Thanks very much woody, very useful Info. I think screws are the way forward for me. 18mm board definitely seem the way to go also. Cheers

Also what are your thoughts on the following: I keep reading conflicting advise about fixing externa. cedar cladding. 1) Secret fixing or front fixed? some say they warp if secret fixed, some say they split if front fixed.. 2) Use spacers? should I leave a 1 or 2mm gap to allow movement in the...

Thanks woody. What type of nailer would you suggest? Cheers

Yes I have many Dewalt XR tools.

Hi all. I have Dewalt tools and want to invest in a nail gun for cladding my extension in cedar. I will be using stainless nails for secret fixing of 18mm cedar. Will the Dewalt DCN660 2nd fix gun be suitable for the job? Cheers

Thanks very much!

Thanks DAZB so I need to rake out 100mm into the existing wall and overlap new with existing. I haven't got an architect, submitted my own plans to building control where I mentioned that new DPC will meet old which was approved, but I see plenty of videos where the builders do not rake out the...

Hi all Couple of questions regarding DPC. I am building an extension which will consist of a timber internal leaf and blockwork external leaf, I have laid the first course of blocks and im at the DPC of the existing brick built house. 1) When connecting the new DPC to the existing, should I...
