    Hello,

    my house was built in 1993 and had a conservatory built on it sometime between then and 2000. Over the last couple of years I have seen the first few courses of bricks + mortar begin to crumble + now I can see the damp course plastic sticking out. Inside, black spots regulary appear, we wipe them off, then they come back again (the paintwork is dark so hides these)...

    I'm thinking I've got damp problem + I'm not sure what to do next so a) I can have my thought confirmed/ruled out + b) I'm not ripped off by someone telling us to pull the conservatory down if we dont need to.

    any thoughts anyone...greatly appreciated.
    thanks

    tony

    is the damp on the house wall or the dwarf wall of the conservatory

    what is the height of the ground level out side the damp area in relation to the dpc (eg one brick level below etc)

    are you sure there are no leaking rain water, drains, or mains water pipe.

    hello...the damp is on the dwarf wall....theres bits on 2 of the 3 sides..

    the ground level (pebbles) is at least 3 brick layers below the damp..

    the ground does have a tendency to hold water but it is dry at the moment...

    just looking at the external brickwork last night, the first 3 courses of bricks are in a right state...faces come off some bricks....mortar crumbling....bricks look white in comparison to rest.

    looking through the docs I have, the house is 11 years old....I guestimate the conserve may be 8-9 years old although no sign of any paperwark...

    I wonder if internally at least, some special paint might help as theres not that much mould....its the outside thats bothering me now!

    could be they have not used engineering quality bricks below DPC,

    with damp on the inside they may have omitted to use an under floor damp proof membrane.

    If things are really bad ring your buildings insurer

    problem is I've not a clue who built the conservatory. Theres no receipts in the deeds and I cant get hold of the previous owners....

    what would be the next step to get it checked out....a builder..a surveyor?...

    is it possible to replace the bottom course without knocking the building down???

    sorry, no ideas with this one

    thanks

    your buildings insurer will probably advise of a surveyor.
