    too big holes for the plug sockets

    Depends on how big the holes are, a few mm and you can probably cover them with grout and caulking (can use silicone but no real need to). Any bigger and you will either have to buy bigger sockets or fashion a plate to go behind the socket. If the sockets are chrome effect you can by sheets...

    adhesive for hardibacker boards

    Don't used ready mixed. Get a decent trade powedered adhesive. Needs to be flexible. BAL I have used and is recommended , there are others. I wouldn't bother pre-drilling the holes in the hardibacker. The force of screwing it should be enough to push the heads down so they counter sync...

    Energy Performance Certificate

    It was introduced when SAP changed to 2009. RdSAP version 9.90. Previously it was a graded system (Good, Very good etc.). The banding spec document is separate from the SAP2009 spec as SAP was previously used outside of EPCs and the information has always been kept separate. It's no...

    Energy Performance Certificate

    Tiling bathroom floor onto span flooring

    Tiling on to the chipboard is not going to go well. You either need to rip up and replace or overboard. Overboarding with ply will increase the height as you say. Take a look at concete boards such as Hardibacker which can be used on the floor, also No More Ply. Both of these products can...

    Vailiant EcoMax Pro Fault 11

    I have a Vailiant Eco Max Pro 28 which was making a noise - sounded like it was constantly on even though there was no demand for heating or hot water. I turned it off and left it for a few minutes then when I have turned it back on it is flashing red and showing a fault code of 11. I know I...

    Advice on tiling corners - trim

    The only other option you might have to is to cut the trims to size then cut off the piece that normally goes behind the tile and use clear silicone to stick the edges down.

    Tiling bathroom floor help

    Remove and tile under. Tiling round it looks crap and is a pain to cut the tiles. Also depending on the style of toilet it can sometimes mean the toilet can then not come out without breaking the tiles. I always remove everything and then tile - event the skirting boards. Costs more and...

    Wall is damp behind bathroom tiles - please help!

    Yes if is concrete board leave it as is - well replace the bits you have removed. Re-tile and then properly seal the gap. With the shower splashing on that edge there is probably a fair bit of water getting down there.

    Wall is damp behind bathroom tiles - please help!

    That looks pretty wet from the photos IS there a shower head above that? If not you need to find out why it is so wet It doesn't look like there is any silicone round the edge so water is getting behind it an wicking up the board Water and plasterboard do not go well together. It...

    Tiling Advice

    I have never done glass tiles so I can't comment on those queries. I assume we are talking about a bathroom here? If that is the case then PVA is not a good idea. PVA softens when it gets wet so it is not a good idea for a wet area like a bathroom. It depends largely on what the...

    Renault clio 16v 2002 starting probelm

    Do you have another car and a set of jump leads? You could try jump starting it and see if that works - cheaper than paying for a battery drop test. Also check the earth wire is free from corroision and attached to the bodywork properly. Inspect the wire going from the battery to the starter...

    Renault clio 16v 2002 starting probelm

    The people who work in quick fit are tyre fitters not mechanics so no surprise they couldn't find the fault. When you say the battery was tested was it a drop test or just a simple check with a multimeter? If the voltage drops too much during a large current draw (starting) then it is...

    Dot & dab + plasterboard or timber + aquapanel for showe

    I would also say aquapanel 100%. Depending on the weight of the tiles this maybe your only option anyway.

    Old wall, heavy tiles, Aquapanel ... way forward ?

    No you cannot dot and dab cement board. The gypsum based adhesive wont bond to the concrete. It also needs an air gap behind it to breath as it will absorb moisture.

    floor tiles on floor tiles

    You could try, but I unless you are carefull with the SDS drill you are going to damage the quary tiles. Also then having to grind off all the adhesive is going to take a long time too. I guess there is no harm in trying. If it goes horribly wrong you will just have to rip it out. As I...

    Annual heat loss kw vs. likely running costs - oil or gas?

    When do you need to decide? If you want I can do some SAP calculations for you and override some of the defaults (No. occupants, potetinal heating patterns etc.) and do a couple of calcs with an oil boiler and one with gas. It wont be completely accurate but should give some rough ideas as...
