    Central Heating Drain Cock

    I need to move the existing drain cock for the central heating. I don't want to add it to the radiator as this will not be the lowest point. It will now be located in the attached garage. Can any one tell me if I can use a union hose to take the pipe through the wall and then attach to the...

    Kitchen Electrics

    I have just completed a kitchen extension and now it needs re wiring. Am i right in thinking that the kitchen sockets need to be on a separate circuit to the rest of the house. Would the kitchen lighting circuit also have to be on a separate circuit to the rest of the house? Finally...

    Blown Cavity Wall Insulation

    Hi I have had cavity wall insulation installed today. It's the type where they drill the hole and blow it into the cavity. I have a few concerns........ 1 - the contractor didn't seal the air bricks below floor level, but there's no sign of the insulation coming through. I would have...

    New Concrete Floor

    I'm laying a new concrete floor on Monday to my existing garage. I'm having to hire an "Easy Float" with the extendable handle as I can't get around the sides to finish it off. I'll level the concrete off using battens that I've screwed to the walls, but how long do I leave the concrete...

    Moisture Resistant Plasterboard

    Just trying to find out whether moisture resistant plasterboard can be skimmed. I'm sure I've read in the past that it can't be. If it can be skimmed, is it OK to use tapered edge as I'm finding it difficult to get square edge? Thanks

    Garage Floor

    Had another thought on this...... Do you think if I was to fix the reinforcement mesh to the existing slab, then add 65mm of fibre reinforced concrete - this would bond and also withstand the weight of the car? Thanks.

    Garage Floor

    It seems a shame to have to dig it up as apart from that one small crack, it's solid. Do you think I could add 65mm concrete (with reinforcement mesh) on top of the existing slab?

    Celotex or Rockwool?

    On the plans for our new extension it states to use "250mm Rockwool Quilt 120mm Celotex into Eaves" - does this mean I can use either Rockwool or Celotex, if so what would be the best? Thanks

    Beam Encasement with Fireline Plasterboard

    I've installed a U beam with timber joists running into either side of the beam. My intentions are to hide the beam in the ceiling area. If I was to use fireline plasterboard on the entire ceiling area of this room (kitchen) would this be classed as encasing the beam. I've also put another U...
