Hi guys I have an issue in my kitchen that a surveyor says is a failure in my damp proofing & my damp man says is only moisture. Its in one corner of my kitchen and 3 sets of solid oak worktops have bowed. Its now starting to make my metal fireplace in the adjacent room go a little rusty. Its...

I have a Victorian property with a basement that is becoming damper over time. One easy fix is to add more ventilation through our coal Chute. Currently, the chute is covered by a square metal cover that can be lifted off the hole in the ground just outside our kitchen window to access the...

Hi there, I'm hoping someone can help advise. I've had two roofers out to look at my attic space, as there is inadequate ventilation in the ceiling void and therefore we've had issues with condensation collecting on the roof felt in winter and it being extremely hot in the summer. Both...

I have a brick garden store, approx 4’ x 10’ that is very damp; I had the roof replaced a while ago, so it’s penetrating rather than leaking. There is currently no ventilation. I’m thinking I probably need to install air bricks at either end to get a through flow of air, but have read...

Hi all I have terrible damp and fungus growth under the wood floor on the ground floor of our typical victorian terraced house. We had a new patio door put in and this has removed the air bricks. Only now do we realise the error of this. So before I go about replacing all the joists and boards...

Hi All, I am currently having my bathroom refurbished. It is an ex council block of flats. The vent already in place appears to be a cover so not sure how this is meant to work i.e. extract steam. Also noticed that no other flat on the block appears to have an electric extractor fan. Can I...

Hi there. I'm looking for some advice related to an issue with our loft if that's ok. Our house is around 300 years old with the original stone roof (not listed). It has two loft cavities with an exterior wall running through the centre of the house. Since moving in 3 years ago we have done...

I have a soil stack in my attic that I discovered is open. I fitted a Durgo AAV but this caused gases to build up and leak out from the bath p trap. I took the Durgo off and the smell stopped. So I'm thinking I need to vent the soil stack externally. My roof is asymmetrical, it rises to the top...

Hi Everyone, We have recently had a new slate roof installed and, at our request, we asked for over fascia vents to be fitted around the entire perimeter of our four-sided hipped roof (which measures about 13m wide by 10m deep). We asked for this form of ventilation as we thought it was the...

My 350m3/h cooker hood is 4.5m from the exterior wall, and is currently connected to an exterior vent with 100mm aluminium ducting inside a bulkhead. I'd like to have better extraction, 500m3/h or more, and it seems like I need 150mm duct for higher powered hoods. Unfortuately the floor has been...

We have recently fitted soffits with 80mm vent grilles every 2metres on our recently converted cob barn. in the double height interior space we can feel a strong draught where previously there was none, the draught is coming from high up, the cob walls are 6m high. This draught wasn't here last...

Hi, iv recently bought a vent axia piv unit. Iv noticed there is a space on the unit where a plug goes possibly for controls. The problem is I cant find any controls for it online, I wondered if there was anyone who could point me in the right direction, or if its not for a controller then...

I want to ventilate a room that has had internal wall insulation applied to it, and the chimney is not ventilated. I was thinking of putting an air vent into the room (where old opening was) but they look a bit unsightly and was thinking it will allow cold air in, or will the hot air leaving...

I (think I am) looking for advice about ventilation! We have recently (2 weeks ago) replaced an old glass lean-to roof with a poly-carb equivalent. We have also replaced the UPVC door. We have already noticed a significant amount of condensation on the underside of the poly-carb roof. My...

Hi We are wanting to buy a property which just came back with a level 3 for damp in the home buyers report. The property is a Victorian terrace with solid floors. There was minor evidence of damp when we viewed but we thought it was just condensation and ventilation issues as the property is...

Hello DIYnotters! Got a few questions regarding damp but some useful info beforehand: Property is end terraced, built around 1990, in Swansea, no subsidence/coal mining nearby and lastly - the house has ventilation grills that cover holes drilled through to the exterior of the building in...

Hello everyone! I own a house built around 1960 and it has these ventilation boxes on the wall. A larger one in the living room, which is wired into the mains (see 1st pic below). And then 3 smaller units in the bedrooms that are mounted higher up and don't have any wires or switches (see 2nd...

Hi all, having a small extension built and so far so good. We’re about halfway up to the roof of the single storey build. Just thinking ahead and have been asking about means of ventilation. Building control have said that the new downstairs WC (containing a toilet only) must have means of...

Hello I'm looking for some advice for how to remedy what appears to be a bodge by a previous owner. I have a standalone single story garage which I'll soon be renovating into a workshop (new plasterboard, insulation, flooring...) but I want to be sure the structure is sound and secure before...

I'm having a new extension and I'm currently ordering the windows. I know er need means of ventilation but I don't want trickle vents (ugly, noisy and inefficient) -- my preference for ventilation is locking the windows on the catch which we have been doing for years now with no problems. I know...
