What did you parge with? Are you brick and block? Where did you use soudatight? How come you taped and didn’t just use soudatight? Are you doing AB before or after plasterboard? Have you had a blower test done?

(expletive deleted)ing hell.

 

You’ve just use your annual quota of questions in one go. 
 

You can post again in 2026 ok.

sorry for the onslaught of questions!!

Yes to brick and block, yes I had a prelim air test done last year, but I cocked up, left a fist sized hole into to the cavity that I’d forgotten about.  The air test did highlight a number of areas for attention though, mainly with air leakage around and behind the roof straps, and a velux which needed some extra attention.  

 

My build is a dormer style build, warm roof. So well taped up, membrane down over the wall plate, soudatight onto blockwork membrane stuck into this and painted over, soudatight liberally painted above ceilings, joists foamed, ct1 sealed and taped at penetrations through blockwork.

Windows all taped up to inner leaf, blockwork again painted with soudatight and then the tape painted over on the inner leaf with soudatight.

 

Basically anywhere I had tape touching blockwork, there was soudatight before and after.

 

Parged with British gypsum soundcoat to all block walls.

 

Cable holes or pipe holes made with a core drill, then a waste pipe used as a sleeve, foaming glue used on pipe before shoving it in the hole, foamed on the inside and painted over with soudatight again.  When cables passed through the pipe would be filled with our favourite illbruck foam then the ends would be ct1’d or ebt’d, and finally a kaflex epdm  what’s’it stuck over for good luck!

 

I’ve plasterboarded the place myself dot and dabbed 1 bag to 2 boards, picture framed the boards, stripes of adhesive at 400 and 800 all round the sockets etc.  Tried my best, probably not as bob on plumb as a pro, but I’m not far off!

 

Reckon the windows and doors will be the weakest link, round the seals.

 

I first spoke to AB 18 months ago, but couldn’t come to terms with the cost, but as time has passed and I’ve now got to the point where I’ve got a spread coming in Jan, I needed to jump one way or the other, so sod it we’ll miss out on our Christmas trip to the sunshine and the lad’s ski trip just got cancelled by the school so that will cover the unbudgeted cost.

Ultimate sacrifices for the tightness of air. 🫡👊👌🤝
