Hi Had an extension built and as part of that had hot water underfloor heating under an anhydride screed floor. The floor went down over six months ago, but for various reasons has only been switched on properly today. A few hours after it was switched on a couple of cracks have appeared...

Hi Need so advice about getting some work certified. Started an extension and had the electrics almost completed when we lost contact with the electrician. Believe it was due to a dispute between the Builder and his electrician over money. How do we go about getting the work signed off so...

Hi I use my loft for storage, and the previous owner (some 20 years ago) used some sort of wall boards (photoboards, I've heard someone call them) to cover the sides. The boards look like they are either a thin ply or hardboard, with waterproof covering on them, which looks like wood...

Hi I've got a 45 sq mtre extension to screed, can anyone give me approx costs for 1) putting 65mm standard sand/cement screed 2) putting 45mm anhydride (flowing) screed. Due to a builder cock-up, I wasn't left enough depth for normal screed and underfloor heating so I've had to resort...

Hi I'm having an extension build and have got my plumber to order some water underfloor heating, but I think my builder hasn't left enough space for it. He has had the concrete poured down as few weeks ago, but the UFH instructions say I need 50mm insulation (which I now have) and then...

Yes

Can these measurements be reduced by using any different materials ? I have underfloor water system, but I don't think the builder has left enough room above the concrete slab for the 50mm insulation and 65mm screed. Can I used a different screed or thinner insulation ?

Hi I'm in the process of updating my heating and boiler system. One of the options open to me is a Storage Combi. I've been told that this should be able to feed more than one tap, due to the built in tank. I was pretty impressed with the write up of the Alpha boiler. Does anyone have...

Hi I'm having an extension this summer and this should give is an additional loft space. Our architect informs us that the loft insulation must be a certain thickness to comply with current regulations. Can I get a thinner insulation that has the same insulating properties, so that I can...
