We recently moved into an old terraced house (c. 1895) with a small front yard. We've just pruned back a large rosebush to find that the guttering downpipe has rusted away and separated from the section that goes underground.

I recently booked a contractor to get rid of the concrete in my garden, and then lay down some turf. Specifically said get rid of all the concrete and then lay the turf. Found out days later the reason my soil remained soaked 24/7 was because he removed some concrete, but the majority of it...

Hi - I am hoping somebody might be able to help me please. As you'll be able to see in the attached photos, I am getting water in brickwork above the DPM after heavy rain. The affected walls (to the left and right of my front door) are covered by a porch and it is not possible for rain water...

Hi, just after a bit of assurance that I'm doing the right thing with my patio plan. The patio will be next to the house and the other side meets the top of a wall, raised from the lawn. I was initially going to have a fall from the house to the garden so water would drain onto the lawn, but...

Hi all, Looking to install a small washroom in the first floor of my house. There is a single bathroom on the ground floor of the property underneath the stair. Wondering how best to connect in to existing drainage. Conscious that Regs state max. 6m for toilet and 3/4m for basin/shower. Without...

Hi, I have a septic tank and I found out my rain water and foul mix and end up in the same tank/drains. This has always been the case since I bought the property 7 years ago and since the drains were put in when the property was built. I've heard they shouldn't mix, however I bought the house...

Hi Our kitchen window has leaked since we moved in, the previous owners tried to fix it by outing sillicone everywhere. Last year we got a window man out and he redid all the seals but said it might be an issue with the render. With the recent bad weather the leak is back, I woke up this...

Hi I'm running a drain through the footing walls and i'm stuck on the section of the building regs that states "openings masked with rigid material and around the pipe should be compressible". Rigid Board I've heard people mention cement board but will this not perish after a few years sat in...

Hi I've recently had my raised front garden taken out so I can make extra car parking space in the front garden. The inspection chamber (see photos) was originally 3 or 4 brick courses high, the biscuit was removed and the courses removed. The biscuit was replaced and is now as low as it can...

Hi All, We are going through a cellar to basement project and just want to ask a few details about the drainage layout and what offers both building regulation coverage, but also what is the most practical solution. We aren't 100% tied to the layout so if a more suitable layout would be...

I'm doing quite an extensive renovation and just want to make sure my plan for the drainage venting is adequate. The house is a mid-terrace and has a flat roof extension at the back, the roof of which I don't want to touch if I can avoid it (trying to limit costs as it was done recently), hence...

Hi I was hoping to pass a foul drainage pipe through the walls under the ground although not sure it's going to work now. As pictured, there is four courses of brick sat on on the concrete ring beam, then the block and beam floor will sit on this. I will need to lintel over the pipe, so that...

Hi, We are building a garden room/office at the back of the garden. We are considering putting in a toilet, but there seems to be only one place to connect it and we are not sure its allowable. Our house is a terrace house and the manhole is at the front of the house. So we need to connect to...
