Hi. I have just finished framing all the internal stud walls in a new property and have got someone plaster boarding all the walls ready for plastering. I have all the copper pipes and waste coming through the floor inside the studs, so the only boxing in will be a short run for the...

Hi. I am looking for a product that will darken both bricks and paving slabs. I have tried a patios seal, but it dries back to it's lighter colour. Is there something I can use that will darken it, so it looks similar to when they're wet. Thanks.

I've just read the IP ratings and from what the guy in the electric wholesalers said, it seems about right. He said that IP65 should be OK for under soffit lighting. From what the ratings state IP66 would be more for driveways or decking areas, where you may use a pressure washer. I...

Hi riveralt. I do trust the Electrician. I recently bought down lights for my bathroom and they were IP65. When I asked him what the difference was he didn't really give me an answer he just said IP66 are the ones he has always used for outside. I just wanted to know myself, so I don't...

Hi. I have 13 downlights/spotlights going under the soffit and need to know which ones to use. The electrician told me to get IP66 ones. Are these the only ones to use? What difference are these to other ones? Cheers.

Hi Paul. I don't know how that calculator works, but I entered everything and that is what came up. The engineer said that it doesn't need much for the heating system, so I cannot really comment on what it has stated. I'm sure that to do it perfectly, you would install a system boiler...

I have just used that calculator and it says. The WINDOW heat loss is 1.32 kW The WALL heat loss is 0.97 kW The ROOF heat loss is 1.00 kW The required boiler output is 8.24 kW. There is a main bathroom and 1 en-suite and I have been told that a combi boiler is fine to use. I...

Hi. Can someone tell me if this statement is true. If you have more than one bathroom in your property then you should have a system boiler installed, so that the flow rate does not get affected when more than one appliance is being used. If you are not going to install a system boiler...

Thanks for the explanation. I thought it was some kind of new build system. Thanks again for all your help.

The property has been built using the following. 100mm concrete block, 110mm cavity with 60mm insulation and then another 100mm block. The cill is protruding 35mm and when they render 15mm thick there will be 20mm overhang. Can you tell me what setup you have done on your property, just...

I've laid a block and beam floor and all the pipes are going under the floor and out below DPC. I've just had the windows fitted. Why do I need to have the cills extended?

I haven't got the experience you guy's have, so it's pointless me commenting on the longevity of render. I personally prefer seeing no drip beads apart from at DPC level and if the that they are used is due to it being easier for the plasterers, then I'll continue to use these guy's as they...

They are using an expansion bead on the rear of the house as it is 14m wide. They are also using drip beads at DPC all around the property. The Gables on the property measure 6.5m wide x 6m at the highest point, so they are pretty large.

Hi. I am asking this question just out of curiosity more than anything else. I am going to be rendering my property soon and have decided to use Parex, which has been advised by the plasterers that specialise in silicone render. They have said that they are not going to use any stop...

Hi. I was thinking about the best way around this last night. At the moment there is a beam and block floor installed and on top of that I need to fit 80mm of insulation and then 70mm of screed. There is 150mm of block protruding on each of the 4 doors at the moment. Could I just...

Thanks Guy's. The BCO said that he was happy for me to use the cavity insulation with DPC, but I forgot to ask him about the bottom of the doors. I was a bit doubtful because some of the tradesmen snubbed there noses when I told them what I was doing, thinking that I was penny pinching...

Hi. Can someone tell me the correct procedure for closing window and door cavities. I know you can buy cavity closers specifically for this, but the BCO has said that he is happy for us to just close the cavity with the 60mm of insulation that we were using for the wall cavity and use some...

Thanks guy's. Don't think I'll be using this guy then if it is a standard thing to do.

Hi. Can someone please confirm the correct way to insulate a floor before screeding. The floor screeder has told me to lay the required insulation (80mm) all over the floor before he comes to lay the screed. I mentioned about laying vertical insulation around the perimeter and he told me...

No, there weren't any instructions. It is getting frustrating buying things online, you can never get things that fit/work perfectly without having to improvise in some way. On another shower valve I fitted the thread of the temperature control was long enough to pass through 12.5mm...
