Hello I have fitted a Nest 3rd gen to an older Potterton 24HE combi boiler. It’s wired as per the instructions from Nest. The hot water won’t come on unless the temperature is increased on the heating using the Nest. Is this normal? Many thanks

Hi I have a small retaining wall (7 courses high, 100ft long). I need to put a 6ft close board fence on top of it. The wall has substantial footings about 12” below ground level. It used to be a 7ft wall. Would I be ok using bolt down metpost brackets on the footings. Then postcrete to ground...

I have an electric shower (Triton T80Z 9.5kW) and a gravity fed system. I also have a pump in the airing cupboard which is being fed from the CWST to the shower. The mains water pressure is good. Why would this pump have been installed? Why wasn't the shower just fed via the incoming mains...

Hi, I'm in the process of laying a new block driveway. Just about finished putting the 150mm Type 1 (granite) down and have a couple of tons left over. I'm putting 100mm of lean mix on top of the type 1 before the sand screed and then the blocks. Over kill I know but it'll have a couple of...

Hi, We have a Viessmann 222-f boiler which has a fault code '1 18' 'broken frost stat cable'. We don't have a frost stat and can't clear the code. We've acknowledged it but it keeps returning. Also has the snowflake icon on the display. Anyone know how to reset it? Cheers, J

Hello All, I fitted a new pillar tap to my cold water supply on the kitchen sink. Now when the tap is opened the water flows briefly before banging then stopping. The pipework from the stopcock tees off to a washing machine valve then to the sink. I've removed the tap from the flexi and...

Hello All, I have a single electric oven which is rated ok to connect with a 3 pin plug. I also have a gas hob which only needs power for the piezo. I'd like to 'hard wire' both of these rather than have 2 sockets taken up with them plugged in. I've got the opportunity to do it properly...

Hello All, Our front garden is bordered by a 4ft hedge which we own and runs parallel to the road. Between the hedge and the road there is an area of grass approx 5ft in width. This land has not and never has been maintained by the council. They maintain the opposite side of the road which...

I'm having recessed downlights (x3) fitted along with a shower extractor fan with a light built in. All to be controlled by a PIR. The extractor is an inline model. It's a ground floor bathroom and the ducting will route approx 500mm before going through an external wall and into a garage...

Hello All, I've replaced the door facings and skirtings in our hallway with soft wood mouldings. The timber was left in the house for a week to allow it to get used to the ambient temperature etc. Do I need to leave it any longer? I have used various caulks in the past, the last one was...

Hello All, I fitted 4 downlights in our dining room about 3 months ago. They are mains powered without transformers all operated by the same switch. For some reason 2 of them have stopped working. I've checked the bulbs (GU10) and they are ok. They have power going to the bulb holders...

Hi, is it normal for the fan to run continuously on this boiler? I have one fitted with UFH and rads upstairs. Even when there's no demand for heat or hot water it is running. :?

Hi, I have a cavity wall mounted meter box which has a 15mm supply routed through the back, into the house supplying a gas fire. The pipework is behind the plasterboard. I would like to have GCH installed as it's currently storage heaters. This would need a new 22mm supply from the meter...

Hello All, I'm replacing the roof covering on a bay window. The current one is sheet lead and is beginning to tear in places. I've got a load of clay peg tiles that I'm going to use instead as they match the rest of the house. Do I need to use a cover flashing where the tiles meet the...

Hello All, I'm trying to identify this composite door. Any ideas? I think it may be a Force8 but I've searched online but can't find any images or info. Cheers, J

Hello All, I've got an area of 60sqm to tile. I have been offered a good deal on a load of 600x600 Marshalls patio slates. These are obviously thicker (20-23mm) than indoor slate floor tiles. We're also having wet UFH which will be screeded to suit the finish. Is there any reason not to...

Is it ok to install a CG lintel directly beneath a timber wall plate or is there a minimum amount of brickwork required between the two? Cheers, J

Hi, We have recently moved into a link-detached house. The survey picked up a number of things but didn't find this problem as it was carried out in the dry spell. The street is on a shallow hill meaning each house is slightly higher than it's neighbour. Each house has a driveway to the...
