Detached house so party wall won’t be applicable. I was of the understanding that gallow brackets are no longer recommended. They’d be much easier…

I want to knock out the chimney breast, just in the ground floor room, leaving the second floor breast and the stack above. I also want any support to be hidden within the floor void. The room is approx 4.5m wide, the external wall on one side is 320mm thick and the internal wall on the other...

Looking to purchase some new windows to fit myself, wanting Rehau frames. Most local fabricators only sell to the trade (which I get), anyone know where I can buy some from? Based in East Yorkshire but happy to purchase from anywhere that delivers nationwide.

It's not really an option. The house is 150+ years old so brick slips will stick out like a sore thumb. Interestingly, it's just occurred to me that the stack dog-legs out half way up the first floor room, so there's not much brickwork that could be tied in to support the stack above the roof...

Detached house, hipped roof. I want to remove the chimney breasts in the ground/first floor rooms as they're no longer used and just take up space. However I'd like to retain the stacks on the roof, as a feature of the property (built around 1880) Pretty straight forward on a gable end, however...

Not sure I follow. If the insulation is glued direct to the wall and cables are run down the warm side of it between the insulation and the stud, back boxes etc will always remain "warm" so water vapour won't condensate?

I’ve seen quite a few posts where insulated plaster board has been removed to show rusting back boxes etc all because moist air from within the house has had direct access to the (cold) rear of the insulation. How do you detail around those types of problems?

I have and decided against it. I want to make sure all joints between the PIR boards are well taped etc to avoid the risk of condensation. (Which I consider the biggest risk of installing internal wall insulation on older houses) I also have a couple of pipes to re-route so plan to have a...

I'm about to start insulating our external walls, internally. I plan to use the "warm batten" method. I.e. sticking PIR to the wall and then mechanically fixing battens through it. The walls I'm tackling first and back to brick, so far from straight/plumb/even, which is complicating matters. Do...

I'm aiming for 125mm of insulation, so whether the infill is 25, 50 or 75mm the total depth to secure would remain the same? No particular reason for the cross battening. If I was to stick 125mm PIR to the wall and then batten to be used as the service void too, I'd actually need to screw into...

I'd prefer to keep the battens on the "warm" side. wall, PIR, battens, PIR infill, cross batten (service void), then PB.

Looking to attach 50mm PIR through 75mm battens to our 215mm solid brick wall. So looking for a conc screen at least 250mm long. Can anyone recommend any?

Best part of £5k for a rewiring our 4 bed house in Yorkshire last year. To be fair, most of that was time spent chasing out the brick walls which were pretty tough going.

I'm planning to install internal wall insulation, with a focus on airtightness, so plan to do entire walls, slab to roof, and cold bridging. The biggest concern I have right now is the 1st floor void and moisture. Our house is solid brick and the joists are pocketed into the wall. So if I don't...

I wasn't massively concerned about internal moist air condensation on the joists as they should never really be anywhere near the dew point (although the joist ends on the outside of the insulation could be). My main concern was any potentially moisture coming into the house from the external...
