    Solid Wall Insulation - Limited Space

    One option would be to hack the plaster off the wall before finishing the wall with insulated plasterboard and skimming. You could easily get another 10-15mm of depth. Something else to consider if you have not already done so is insulating the floor. A 1920's house is likely to have a...

    Do I have a cellar or do I not?

    Possibly even easier is to get a cheap USB inspection camera. Have a quick search on eBay. You can get a waterproof camera with 5m+ of cable with LED illumination on the end for ~£15. Even if you do remove an air brick you will probably get a better idea of what is down there with an...

    will wireless thermostat clash with wireless PC router?

    Unlikely the wireless thermostat is likely to run in the 433MHz band as the 2.4GHz band is rather power hungry has low range at low powers. It's used by wireless doorbells, keyfobs, remote temperature sensors for weather stations etc.

    Another loft boarding question...

    They might say that, but if you are using it for "light" storage you don't actually need it. My sisters loft has been down for two years now and it is doing just fine. There is no sign of the crushing that Celotex suggest and the storage is more than just empty boxes. Now if it where a floor...

    Chalet Bungalow - Whats the best sort of insulation?

    The best way would involve pulling the plasterboard off in both the green and blue areas. In the green areas filling between the timbers to full depth with celotex/kingspan and in the blue areas leaving a 50mm gap between the roof and the top of the celotex/kingspan. You then cover the lot with...

    Boarding loft for storage ?

    It's a lot quicker to simply order up some 100mm kingspan/celotex cut it up into strips to feed through the loft hatch, lay over the joists and then cover with loft boards. It is also not that much more expensive, and you loose less height in the loft and get lots of extra insulation. I have...

    Attaching skirting boards to wall, gap at bottom of plaster

    It would have been much quicker to mix up some hardwall or browning and just fill the gap in. Would also reduce the draughts.

    Internal lagging

    Your plumber is simply plain wrong. Building regulations say that internal cold water pipes are supposed to be insulated so the water remains cold on a hot day :-) All hot water pipes should also be insulated so water stays hotter in the pipes longer. Of course it also helps prevent pipe...

    between two walls carport,,,,attached to mine..

    Note if the wall really is the boundary, then from the photo it looks like the eves of his roof overhang your property, in which case he is in the wrong and it could get rather expensive for him should you demand he remove them.

    Unsure how to replace and insulate upstairs sub floor

    That is not strictly true. For example in my house without insulation between the lounge and the bedroom above when the lounge hits 20-21°C the bedroom would be ~23°C. Fairly basic thermodynamics really. By sticking some insulation under the floorboards of the bedroom, I can have the lounge...

    Celotex over joists for attic floor

    I stuck 100mm celotex directly on the joists followed by 18mm loft panels in my sisters house a couple of years ago and so far no problems. Not sure what the joist spacing was, and I left the 100mm insulation between the joists in place. As long as you are not going crazy with the amount of...

    Must all bathrooms have an extractor ?

    Yes and no. Windows even when open are poor ways to remove condensation from a bathroom, especially in winter. The thing to bear in mind is because you have an opening window there is no requirement for the fan to come on when the light comes on, which is the usual objection to having a fan. Put...

    Continental plugs don't have fuses, so why does UK?

    As I stated earlier a 3A flex on a 15/16A radial circuit is still unsafe and still needs fusing for maximum safety. The alternative is to use properly rated cable for all flexes. However this is bulky and leads to use of large amounts of copper so is not done. Consequently while the...

    Continental plugs don't have fuses, so why does UK?

    Now imagine that we had 15/16A radial circuits with fused plugs, and shutters and all the other features of BS1363, and someone said let's remove the fuses from the plugs, remove the shutters and switch to unpolarised plugs. It is my opinion that fused plugs and shuttered/polarized sockets...

    Continental plugs don't have fuses, so why does UK?

    Which brings Part P into light as a huge waste of money. Put another way for the same cost you could have saved many more lives doing other things. That said there are a lot of electrical fires, and while few cause any deaths it should give a clue as to where the risk lies. Again it mostly...

    Continental plugs don't have fuses, so why does UK?

    Higher rates of death and injury I would imagine is the main difference. Needing everything to be double pole switched another.

    Old Style Light switch box

    It is most likely cast iron which makes extraction easy than you think once you know how. The trick is to use a Dremel tile cutting bit in a drill or one of those multitool things to cut a neat square out of the plaster back to the brick exposing the cast iron fitting which is screwed onto the...
