ventilation

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...

Hi, There's a mouldy smell in my shower room, and I think it may be coming from the extractor fan. I removed the cover and cleaned around the motor and blades, which were pretty black, but I couldn't reach into the ducting. First, I'd like to know if mould in extractor fan ducting is a thing...

Hi, My bathoom extractor and kitchen one both just have slat type grilles, I'm wondering if they really should have those flap things on the ends ? Maybe the moisture is blowing back into the rest of the flat from the shower? Or maybe just a downward facing cowl ? They have square ducting...
