    Patio higher than DPC and new foundations

We have had a small new extension put in with bifold doors in place however the foundations and new DPC are below the patio. Unfortunately the...

    Something to place beneath new built wall so when wall removed leaves no marks on floor?

    I am getting a polished concrete floor. After it is finished I will be rebuilding a small dense concrete block partition wall. However, it is likely I will take this wall down at some point. I don't want staining/marking on the polished floor should I ever remove this wall. So thinking of...

    Damp issues

    Hello, First time forum user, I'm looking for some advice on whether a chemical DPC is necessary. It's a circa 1900 mid terrace house. The survey showed high damp readings on the front external wall and the recommendation is the standard chemical DPC and replastering with a waterproof sand...

    Damp Survey - Confused…

    Will try to keep this as concise as possible... I'm buying a small victorian terrace (it's Grade II listed). It hasn't been particularly well cared for and has what appears to be significant damp problems in the ground floor front room. It is solid floor construction with no cellar so there...

    Bridged dpc?

    We have just had an extension built and have noticed that our next door neighbours have quite bad damp (albeit under their dpc) however our corner that touches theirs is now becoming damp. Looking at the images our dpc is visible and then disappears closer to their wall. Should this be exposed...

    ?Oversailing at DPC

    I've lived in my current house for over 20 years now- 1940s semi. I must admit, I never pay close attention to brick work etc, but I know there are no cracks or obvious signs of subsidence. I'm planning on resurfacing my driveway and as part of this, I've had a really good look at the DPC. I...

    Painting DPC - any tips?!

    We’re having our bungalow cladded with Cedral cladding. The cladding can’t go below the DPC and for aesthetic reasons we’d like to paint DPC white - the reddish brick against light grey cladding doesn’t look right to us. Before shelling out for the painting to be done professionally, I’d like...

    Does anybody have a diagram or drawing showing how the lower corner of a window sill is constructed, and how the DPC and cavity closers join/overlap to form a waterproof joint? I have recessed windows (i.e. they sit in the middle of the wall), and will be making a sub-sill from creasing tiles...
