    Seal felt around internal soil stack

    Our internal soil stacks are attached to external vents on our roof and the felt has not been sealed around the pipes. The wind howls through the attic space as there’s plenty of ventilation at the soffits and along the ridge line. See attached photos. Is this a standard / best practice type of...

    Loft Insulation Material

    Hi there, We've just moved house and I'm about to sort loft insulation in the property (it's between the joists but not across - and certainly not up to the 270mm we want to aim for). A couple of questions if that's ok: 1. Any suggestions on which type of loft insulation? We are looking at...

    Roof needs reinforcing ?

    Hi all, I'm in the process of buying a property. The RICS surveyor flagged the roof as being problematic: the purlin towards the front of the house seems to have moved by a few cm and is not fully resting on the diagonal support along its length or on the metal support in the party wall. -...

    Laying new loft insulation over old

    I've been upgrading my loft insulation. 1950s house. I have joists that are about 130mm deep. In between the joists, there was a thin layer of old glass fibre insulation and what looked like rockwool insulation over that. The insulation varied in depth and was ~75mm deep at best, ie at least...

    Loft: Random plasterboard between rafters - why?

    I have come across some random plasterboard in-between a few of our loft rafters. The previous owners had a two-storey extension built 10 years ago with some new roofing that joined onto the existing roof. There is some overlap between new roof felt (beathable) and the old existing felt (the...

    Insulating both joists and rafters?

    Given the massive rise in energy bills coming, insulation is going to lead to much bigger savings on energy bills. Yet our loft is low and so I have a rather unusual issue - I can't insulate it to 270mm. I have just a 100mm cavity between the joists in our loft and insufficient height to raise...

    No joist in front of loft hatch?

    I'm currently re-securing the ceiling in our bedroom as it has a bulge above the bed that is disconcerting. I've managed to find the joists either side of the loft hatch but cannot for the life of me find one between them, it's a gap of almost a meter. Any ideas? Is it possible that there are...

The house has a loft conversion, and when we bought it the survey highlighted that it didn't meet current fire regs since it is open to the stairwell , i.e. stairs go to first floor, and then curl round and go up into the middle...

    Hi all, We're battling serious water damage on the second-floor front wall of our Victorian semi (pic 1). There are no visible issues on the exterior. The previous owners advised that it was caused by an unresolved roof leak. They finally got the front re-roofed but didn't repair the damage...

    Insulating Loft Futureproofed for Converting

    Hi. I need to increase my loft insulation but would like to have the loft converted in a couple of years. What would be the most efficient way to do this, reducing waste if it’s converted? It’s currently boarded, which is useful, so I think I’d rather insulate at roof level. Would PIR boards...
