    Is this a party wall or not?

    A party wall must have room on either side. The PWA may apply to building a wall near a boundary, but that won't make the wall a party wall

    Insulating a window reveal

    Hmmm, maybe. I think it's best to bear in mind the principles of using some insulation, not necessarily the same thickness as the other walls, and minimise cold surfaces and bridging, and do what's easiest at least cost.

    Mansard roof flat

    It's not an issue at all. Your advisor needs to check what replacement works are planned for the near future and your liabilities for costs

    New Roof - Cause For Concern ?

    What's above those drips? Where are they coming from? You need to determine if this is condensation or not. For info, the breather membranes the industry sold us are not as breathable as they claimed, and condensation issues are rife even when everything about a roof is done "right". Over the...

    New Roof - Cause For Concern ?

    There should be no wet spots from water penetration below a new roof. The breather membrane should be fitted with a sag between the rafters to aid air flow and any condensation run-off. Not all breather membranes breathe to the same extent. Most of the condensation in a roof void is caused by...

    Acrow, push-pull or bottlejack for supporting purlin for repair

    It's either/ivor for multiple screws or a few bolts. The benefit of screws is that the fixing is spread over a wider area of timber and not limited to just a few locations and axis in the timber. The screws also pull all the ply to the purlin, not just at the locations of the bolts. PU tends to...

    Large Crack (more than an Inch) Exterior Wall

    Nothing you do will stop that wall moving so any rigid repair will invariably re-crack to some extent - normally hairline if the cracking is as wide as it will ever be and the wall settled bar for any slight seasonal thermal movement. So it may be best to use a flexible filling material like...

    Insulating a window reveal

    Don't skim and decorate straight on the board, saving 3mm. Or use foam adhesive and rely on that and air, and you won't have any practical or demonstratable difference Or shave the insulation board or fit a thinner board, likewise you won't notice any difference. Introducing a cold cement...

    Large Crack (more than an Inch) Exterior Wall

    I would not mess about with it too much - the existing finish is not spectacular and there is a big chance that the wall will continue to move slightly in any case. Look for trowel mastic, it comes in a tub and is err applied with a trowel. It remains flexible to deal with minor movement, and...

    Door between kitchen and conservatory

    What's the cost, convenience and aesthetics of doing all that instead of just putting the heating on low for a few hours to take the cill off and stop the draughts?

    Non Standard Size Driveway Extension

    Check your property planning permission conditions, see what rights have been removed - all or just specific, or if subsequent PD rights are included. There are no size criteria, or what you plan to do with it. For your purpose, its just a hard standing that's all you need to state, and the...

    Retrofitting restraint straps to joists in existing 9inch brick wall

    A situational sketch would help. I'm a little confused with the terminology of "spanning on to the face" (is that face fix or bearing on top? Wall plate (top of wall) or ledger plate (on face of wall)? If the plate is bolted, isn't that doing the restraining? Or are these lateral restraints...

    Roofing Brace Question

    What do you mean by braces? Do you mean collars, ties? You would not use Revit for this, it's no help

    Roofing Brace Question

    Firstly, it looks like you have some wood-boring insect attack to at least the wall plates and joists, and some damp timber to the horizontal gutter - are those being addressed? It looks feasible to create a raised collar roof by lifting those ceiling joists or even removing them and relying on...

    Mould and staining on ceilings in bedrooms

    Yellow staining is normally water penetration. However, some smaller splattered or grease-like stains can be condensation related. Small less frequent drips can lead to small stains that do not get past a certain size. Black mould is invariably condensation related, however the blown paint on...

    Acrow, push-pull or bottlejack for supporting purlin for repair

    You only need to stop the purlin from deflecting more, not try and jack it up - which you are unlikely to be able to do and would potentially cause more problems than it solves. 2x 600mm 12mm Ply strips over the split area, glued and screwed will do.

    Is this asbestos

    Those look like vinyl floor tiles. If so, and if they are more than 9" square, they are non asbestos.

    Do I actually need to damp-proof an old brick wall, or just contain the damp?

    A damp wall behind panelling is going to warp or split the panels, but probably not before fungus starts to eat away at them.

    Approx cost for work, (for budget purposes) and some questions.

    Competency schemes such as FENSA do not cover the structural opening alterations, and those will require a building regulation application for the openings and the frames fitted into it.

    Damp patches after heavy rain on roof rafters and membrane. Rafters root?

    Many of those old council system-built houses tend to have a very low or flat area at the eaves, which can have some water ponding. That membrane should be resisting penetration regardless, so it is either creeping sideways under the lap or it's via a nail hole. Sometimes a worn or badly...
