    Will Masonary sealer cure damp? (Ed.)

    Very bad picture but these are the pots. Only one flue is live but got them both capped.

    Will Masonary sealer cure damp? (Ed.)

    So the entire roof and leading is being replaced next week so back gutter and all chimney soakers and flashing will be renewed. Just wondering if it's wise to get the chimney stack sealed at the same time to cover all eventualities?

    Will Masonary sealer cure damp? (Ed.)

    Ah ok, fingers crossed it sorts itself once the roof has been replaced!

    Will Masonary sealer cure damp? (Ed.)

    Next week we are getting a roof replaced as its leaking like a sieve. The house was built in 1901 and still has it's 2 original Yorkshire stone chimneys. We are having issues with a damp chimney breast where the chimney bricks under the roof line are wet after heavy rain, mold starting to form...

    chimney leak or brick saturation?

    We have an issue where a part of one of our chimney stacks just under the roof and in the loft gets wet during rainfall, it is an 121 year old house and both brick and mortar are soaking. It has been happening for a while, getting wet when raining about 4/5 bricks down, dries out when not and...

    Leaking Dormer window a roof leak or failed window?

    Unfortunately I can't get access around the frame as the window doesn't open and the frame is embedded into the dormer walls so without carving into the wooden surrounds Its not possible. Ive got a roofer coming tomorrow so fingers crossed but nearly 100% sure it's a window fault rather than...

    Leaking Dormer window a roof leak or failed window?

    Yes very true. If it happens again might try and take all the beading off whilst it's raining and see exactly where this water is coming in from. The top part of the beading was bone dry when I last removed it which makes me suspicious that it's a roof leak and the water entering from the top of...

    Leaking Dormer window a roof leak or failed window?

    We have lived in the house for 1.5 years but we had high winds and driving rain last night and woke up to water coming out of one of our attic bedroom dormer UPVC windows and down the wall, but from within the frame itself which has never happened before. The pictures below shows where the water...

    Enough natural ventilation to create through-draft in cellar?

    So I left the window on a latch for about 2 weeks whilst we were away, dehumidifier was off. Came back to a very wet smelling cellar and mold everywhere. Back to window closed and dehumidifier on but am I best sealing up the air brick as well or just leave that as it is?

    Enough natural ventilation to create through-draft in cellar?

    Ok great, the room is in the attic and currently has the window on a latch 24/7 to create a through draft with the air brick but it's still a tad moldy so presume when dehumidifing I need to close the window fully and then just leave the air brick as it is as otherwise the dry air will just get...

    Enough natural ventilation to create through-draft in cellar?

    Thanks again all. Bit of a random one for another room, if I use a dehumidifier in a room with an air brick will it be relatively pointless as I will just be dehumidifing the outside air and losing my dryer air back out the air brick?

    Enough natural ventilation to create through-draft in cellar?

    Sorry what do you mean by external extractor fan?

    Enough natural ventilation to create through-draft in cellar?

    Sorry I'm really confused now. What's the best course of action then? 1) leave it as it is as if it's not broke with the dehumidifier don't fix it? 2) just keep the window slightly open 24/7 and create through draft through the room to the stairs/ air vent. 3) Do purge ventilation a few times...

    Enough natural ventilation to create through-draft in cellar?

    Thank you, I think a humidity controlled fan sucking air out of the cellar sounds the way to go as the room is unheated so last thing I want to do is suck in very humid external air which will condense in the cellar. I guess I could heat the room but the temperature hovers around 16/17 degrees...

    Enough natural ventilation to create through-draft in cellar?

    So potentially get a humidity controlled fan, can get 1 installed under the window, and just use that to extract air24/7?

    Enough natural ventilation to create through-draft in cellar?

    Need a bit of advice: We moved into a 1901 house last year with a converted cellar done in 2020, cellar was always dry and never flooded before conversion. Within 2 weeks of moving in we had a washing machine leak so bought a dehumidifier to dry the cellar back out and since then just left the...

    Heat recovery exchange fan or normal humidity controlled fan for cellar?

    I have 1 air vent on 1 wall and a window on the other so did have a window on a latch 24/7 for a few months but then read that when it is warmer/ more humid outside then all you do is make the issue worse by dragging in warm air into a cold cellar so soon shut the window.

    Heat recovery exchange fan or normal humidity controlled fan for cellar?

    Thank you for the comprehensive reply, that is great. Looking at the above maybe a simple humidity controlled fan would be better. I already have a powerful air purifier down in the cellar to help with air circulation and to trap mold and I do have a large dehumidifier but it's 320W so very...
