Nosy's post implied they would not work at all. Our's works 99% of the time when it rains, but when it fails, the run off just goes down the garden which does not matter as it is pouring down everywhere anyway. Also our's is of smaller volume than that proposed by nosy and therefore if it was...

Rake out the gaps as deep as you can, then repoint gaps with morta to prevent sound transfer from next door, then replaster

I cannot understand, pictures required

I aint goot aa clue wot u saing mait.

Sorry nosy, but I disagree, we have a soakaway in clay soil and it only overflows under heavy prolonged rain. If the OP's ground layout can cope with occasional overflow, no problem. Personaly, I would drain the water into a water butt(s) and direct the overflow from the butt into the...

I have black mold growing on a wall behind where the washing machine is. I am encouraging it to grow by using a biological washing liquid with the wash and hope that a new life form will evolve from it within my lifetime. BTW I am a Dr Who fan.

BRE say a sealed reflective cavity has an R-value of 0.44 BRE are THE recognised independent reliable source for building info. The link you have provided is a commercial body. Tip: If BRE have data on something obtained by their own test methods, quote their data only...

I have only now read your origonal post. Yes a 9" brick wall has a U value of around 2.5, but putting in a reflective cavity brings it down to 1.0? I don't think so! Do you have the BRE 'hot-box' data that proves your U value of 1.0? From memory a 11" brick wall with 50mm cavity has a U value...

forgot to mention, you should have had the heating on in the daytime for this test and had the heating on in the house over the last few days so the wall structure is it at a typical temperature, but you would have the heating on to some extent in the daytime anyway wouldn't you? With the...

My filing cabinet metal outer in a room at 22C feels cold to the touch, it feels this way because my hand is around 35C. wrting that a wall is cold to the touch is too vauge. To be scientific, please post here the temperatures of the cold wall day and night and also the room air temperature day...

I think the above is how the Law is currently, whatever the planningportal guide or LBO might say, remember their advice has a disclaimer. A friend of mine had a LBO tell him that if you built a brick outbuilding (smaller than the 15/30m3 BC limit) as soon as you incorporated some...

The extract below is taken from this page: http://www.planningportal.gov.uk/permission/commonprojects/externalwalls/ Note how they spell lintel and at the end that it is only a 'This is an introductory guide and is not a definitive source of legal information'. My feeling is if the person...

In most cases an external wall will have more than one room as part of it, so if just one room is replastered or have its plaster removed to gain a couple of cm you may be under the 25% limit. And unless you tell BC what you are doing, how could they know?

To continue this vauge theme, all I know is when you buy something heavy at put it in your wagon, it weighs twice as much when you unload it the next day...

I agree, geraint = troll he has won the 'most trolled thread award' for this season.

Instead of spreading rumours, why don't you first ring your local LABC and get them to confirm or deny your 'suspicion' that adding some insulation to your existing house would come under building control. Whatever they say, ask for the government website URL so we can see this in writing, since...

I had assumed (because I could not see in the photo) that the rafters were resting on a corner of the purlin without a notch cut out of the rafter. If the rafter does have a notch like the one cut in the rafter over the wall plate, - and I sure it does, no one would design a roof with a rafter...

Wrong! Having thought further on this matter, the trussed purlins are trussed because there is not a central supporting wall for the purlins to be supported via struts. Therefore underneath that insulation there must be horizontal joists coupling the front and the back rafters together...

Doesn't the 'usual thing' also involve looking at the DPC outside and inside(by lifting floorboards), DPC height above ground, DPC type etc. What were your findings on these points? I have used silicone treatment at home but I would only recommend a siliconate transfusion which is a...

My 1928 house has such a 'skirt'. I call it a plinth, but I don't know the correct name. If you remove it you reveal the ugly common bricks and slate DPC formed from multi layers of slate. Its purpose is to conceal the rough slate DPC and to weatherproof the common bricks. Yes it does...
