ventilation

Hi I will be using periscope vents to air under a block and beam floor and wondered about the below ground cavity fill. All the regs say to fill the cavity to 225mm below DPC although this will partly encase the vents in said concrete; is that okay? Also when I am at DPC the building inspector...

I've built a garden office last year and is well insulated, breathable membrane, air gap then cladding for breathable aspects. On the warm side i.e. before internal walls is vapour barrier which I research as the best for stopping moisture in winter, and effectively creating a sealed box. The...

I've just moved into a late-Victorian, mid-terrace property with a great space in the cellar that we want to use as a storage/utility area. While there is a useable drain, there is no ventilation to the space and I'd like to make sure I'm on the right track with my plans. Two surveys didn't...

Hi -- I've looked through the archive but can't find an answer to this particular question, so I apologise if it's a repeat. I've just moved into a mid-terrace Victorian house (c.1880) and I'm fixing up the suspended wood floor in the downstairs; this includes putting celotex in between the...

I'm social housing tenant and I had a survey from a company called Airtech as we have condensation on the bedroom windows. Recommendations were to change fans in bathroom and kitchen to ones with a humidistat, and install passive air vents in the 2 bedrooms. The housing emailed me with the...

Hi, I hope to install 10cm diameter round vents into the casing above our patio doors in the kitchen. My monitor tells me the space behind the plastic fascia is empty. Can anyone forsee a problem with this e.g. breaking weatherproof seals? I'm wondering about installing the vents external in...

Hi guys. New user....hope you can point me in the right direction. One of my rooms on the ground floor (of terraced house) has a bricked up fireplace but the chimney was not capped. I had that done a few years after moving in as paint work started flaking on one of the chimney's adjacent...

Hello folks, whilst getting ready to paint our upstairs box room to make it into a nursery, I unscrewed a metal grill vent, and found a small cavity packed with old newspaper. I'm fairly certain fungus-riddled newspaper isn't ideal for a baby's room but should I just clear it out completely (and...

Hi guys, Long time lurker. Remodelling a flat to convert recesses into an internal kitchen, very common in these parts. There will be no windows, just a door into the hallway. My question is this: am I allowed to have a gas hob in it? I thought it was allowed with the appropriate mechanical...

We have a Victorian terraced house, with timber joists/floor on the ground floor. We have 3 double (flood proof) airbricks to the front of the property, however, at some point in the past a large extension was built across the entire back of the house with concrete floors and we do not have any...

We have a sorted of converted loft space, which is carpeted, have plasterboard ceiling and a narrow staircase from first floor. After moved in 2 months ago, we noticed in the last 2-3 weekend that there are a lot white mould on the front ( north facing) and side of the ceiling, and it is...

Hi Everyone. Just joined the forum today. I've bought some parts already to make a downstairs toilet for more convenience. I got a builder to get the job done. So far I have the way hung toilet pan+cistern, cloakroom sing & taps. I need to ask couple of advice.. 1: where will be the best place...

Hi all, So I finally finished painting a house that the family and I moved into a few months ago and woke up this morning to a large patch of wet running what I believe is condensation in the living room. (File attached). Ironically I packed away all my paint brushes yesterday! I had a look at...

Hi all, My ground floor is of beam and block construction with a 150mm or so void underneath. I initially thought it had no airbricks whatsoever although I found out they had simply been covered / blocked by garden soil, patio slabs, etc. I've read that the void needs to be ventilated and my...

As my builder buggered off without putting in the soffit vents I had BC out last week and lo and behold it's changed and we need cross ventilation on the flat roof of my extension and we're not able to just put in the soffit vents on the front overhang, but rather being asked to do it from side...

Hi everyone I'm not sure if this is the ideal area to post this, but I'm hoping you can help me make sure I've got the right idea about some work that needs doing in a house I'm buying. The place is a 1974 semi which originally had a gas fire. The current owners had this removed - the gas...

I took of the square white plate from the living-room wall to find a circular hole going right through to the outside with nothing in-between apart from another white plate at the outside end wall. I have to say I removed the inside wall plate as I was curious to know why there was plastic...

Hi everyone First time buyer here who is keen to listen and learn from the experienced people. About 8 months ago we bought a 1930's end of terrace property. Since then we have noticed a significant issue with 'rising damp' and as such we have some dry-rot in the floor joists and floor boards...

We have submitted plans to build a new rear 4 metre extension to our mid-terrace house that is being opposed by our neighbour. The neighbour already has a 20 year old 4 metre rear extension built 300mm (12 inches) inside his property boundary. He has two ventilation openings (airbricks) on each...

I currently have a an in line duct fan controlled by a humidistat in my bathroom and it works well, extracting the air when I have a shower. Unfortunately the humidistat cannot tell when there is an unpleasant odour in there and I have been looking for another way to switch the fan on for 5...
