Hi, first post on the plastering section. Has anyone used aluminium corner bead, .e.g http://plasterfittings.co.uk/index.php?route=product/category&path=37_39 Any reason not to ? The odd problem with galv edges that have been cut in damp rooms comes up, alu could solve this problem...

Thats the funniest thing I've seen in ages ! Surely they should have had a few steps the other side of the door ? Or moved the doorway back inside a bit to allow some more steps. Could they be part way through the job ? Simon.

You need to think about cold winters and protect the plumbing etc. What I would do assuming a lean-to is the best option and you have no space for an internal door, is to insulate / weather-proof it very well and have an opening from the house (window, "hole", etc) so the lean-to gets heated...

Well I would see if the celotex fits in the 100mm wall first (by trying it at the timber yard !) This will allow for the fact that timber is often planed to a smaller dimension than the nominal size. For this reason you may have to use a wider wall. And if there are any doors in the wall, make...

I have used frame fixings in the past (hammer or screw) to fix a wall plate to bricks (usually at roof level though !) If need be (bricks not level enough), this can be bedded on mortar. Its also possible to use no-more-nails / gripfill type adhesive. Plasterboard can go anywhere as long as...

I had some that matches that description from a seconds supply company. There was some kingspan and some of the pink stuff all mixed up. The building control guy did not comment, so he must have seen it before. If its the correct thickness and has shiny foil, it will do ! The U values for all...

The roof probably needs to be designed and/or checked by a structural engineer. Anyway, its quite normal to have dwarf walls down to a steel to offer rafter support, combined with a ridge beam and / or tie beams at ceiling height (forming a type of A frame). Or you can get loft trusses made up...

If you had (not cowboy) builders in doing the work, they'd not give it a moments thought. Lots of builds get saturated before the roof is on. They always dry out in the end somehow. This happened during my build and I've have no problems. Its possible to think too much ! Simon.

Two things. 1. The DPM under the slabs should have been joined / overlapped - has this been done ? 2. Relative movement between slabs ? Has the new slab been joined to the old with rebar ? If not cutting slots and inserting resin fixings is possible. Otherwise you could get some slight...

Does the strip of polystyrene (1) fill the cavity or (2) is it a thin strip and actually an insulated DPC ? If (2), cavity closers like that seem pretty normal. Mine had some clips you can use to screw into the inner leaf but a push fit is OK. Put plastic strip against the outer leaf - it will...

You can have a gap in the foundations and a lintel over the pipe (one for each leaf of a cavity wall). If there is enough depth, the founds should go under the pipe, leaving a square gap for the pipe. Fill all around with pea shingle etc. Use shuttering to keep the pipe gap free of concrete...

Another trick I picked up somewhere. If you screw a bit of board (OSB etc) in the middle of the previous board so it sticks out past the end, you can slide the next board above the little ledge created, and it magically stays there ! When done, take this down and use for the next board. A dead...

I prefer building in at both ends if possible - it's more solid. Round here you see lots of extensions going in with holes knocked in the original house wall to take joists. However, ledger board and hangers are OK of course. In theory the lightweight blocks can usually take the joists direct...

Well I would remove one or two bricks near the middle about half way down, where it would not cause any structural problems, then have a look around in there with at torch. How I would proceed from there would depend entirely on what I saw inside ! It could be for support, such as a couple of...

These boards enable you to "get past" building regulations, and as we all know that is all that matters. Simon.

Plasterboard or finishing timber to box in the bearers / joists. No matter if bolt is a short way inside the last joist, as long as the bearer is substantial enough (same size as the joists ?) Best not to hide the bolts, so they can be tightened if (when) the timbers shrink. By the way, I...

vaillant turbomax plus 824E - can anyone tell me where physically the expansion vessel and recharging valve is. I cannot find it anywhere. Thanks, Simon.

Vaillant turbomax plus 824E Could get photo later when missus brings camera home. Simon.

By flow regulator, do you mean (off the schematic diagram): Modulating gas valve (I guess not) Diverter valve Aqua sensor (DHW flow switch) ? Simon

Hi, first post to the plumbing section ;-) My vaillant turbomax boiler has started making a juddering moaning noise when the hot water is on. It does not do it with the central heating. Sometimes it is constant, sometimes intermittant. If the water is run very slowly (still triggering the...
