    Underfloor mechanical ventilation/fans

    We dry clothes in the box room in winter with a dehumidifier. This is the one room in the house which doesn't smell! Most of the (PVC double glazed) windows are vented - I retro-fitted a few that weren't.

    Underfloor mechanical ventilation/fans

    Hi foxhole - 18 airbricks all round, extractors in the bathroom and kitchen. We also have a ceiling mounted PIV on a low setting in the middle of the house. So quite a lot - or at least as far as my experience goes, and also why I am a bit baffled!

    Poured reinforced concrete lintel and French doors

    Just to finish this off, I tried using various detectors with unclear results, so I ended up cutting out this section of the beam. As it turns out, there were 2 runs of rebar at one end, but this stopped well short of the end of the existing opening, so it was a bit if a lash up in the end as I...

    Underfloor mechanical ventilation/fans

    Hi all - I have run out of ideas as to how to fix a condensation problem. Situation is 1960s bungalow in Cornwall (not great construction and high humidity generally) with a suspended wooden floor. I replaced the floor across one side of the house when we bought it about 5 years ago due to a...

    Poured reinforced concrete lintel and French doors

    Thanks Himaginn - I understand your logic. If I was sure the ring beam (it definitely is that) had reinforcement all the way around I would be very happy to leave it and cut out the opening. What I am trying to avoid is short lengths of reinforcing over the existing door and window opening...

    Poured reinforced concrete lintel and French doors

    Hi - I am not sure what I can do about the photos not enlarging. The wall is 9" hollow block. I think it is a ring beam cast in place. There are no joins running all the way around the top of the walls. I am assuming there is some rebar over the openings because when I removed an extension...

    Poured reinforced concrete lintel and French doors

    Thanks guys - I like the lateral thinking with the metal detector! I will see if I can whistle one up. Woody - here are some photos of the job. A 5' wide doorway would just overlap the window opening which I was going to block up with 9" hollow blocks (the rest of this wall is made of them...

    Poured reinforced concrete lintel and French doors

    Hello - I would like to fit French doors into the back wall of our garage. It is concrete block, flat roof construction, tacked on the side of our ~1965 built bungalow. From what I can make out, the walls of the house and garage have been built with a concrete lintel poured in situ all the way...

    Flat roof repair after removing concrete gutter

    Hi - the leak is at one end of the felted gutter (it pools there). I know I will have to replace the deck in this area, but along the rest of the length of the gutter it is sound and has not been wet. I guess my question is really about what roofing materials will bond to another, as in the...

    Flat roof repair after removing concrete gutter

    Hello - we have a flat roof over our kitchen - good nick, but probably 10 year old at least I would think. The roof but up to the main building (bungalow) just under a concrete gutter. The roofers have basically run the felt from the flat roof right over the gutter. It leaks and is pooling...
