(Originally posted in buildhub and reddit/r/DIYUK) Dear all, I am sharing my experience of replacing a worn bearing of a Nuaire MRXBOX95AB-LP1 MVHR fan/motor. Hope this will help someone someday. Back story A few months back my NVHR is getting noisy and noisier. After contacting a third...

Any thoughts on insulating this kitchen wall? It's an extrrnal cavity wall but not insulated as far as I can tell. See last pic which is vent from the outside. Loads of condensation when cooking ect (despite opening windows). Also plenty of condensation around this vent (which i assume in part...

After some advice please on refurb project. Recently studded out the old solid stone walls on house refurb project, insulated with breathable insulation and installed VCL. Concerned about mould growth on the solid stone wall behind the insulated stud wall tho. What is the best way to...

I dont want to have fan and want to use the hot to cold air law to provide hot air with escape route in my bathroom. So if i run a straight ducting pupe through the ceiling above shower and then roof will there be any issues? One that bothers me is if the pipe is straight the rain may drop in...

Hi hoping for some help. We’ve inherited a feature fire with an open gas unit. It’s a Royal CozyFire 16” Inset Taper. We’ve found an old vent to outside the house which was blocked up with junk. I’ve had a few gas guys turn up with different opinions as the unit is under 7kw I don’t need a...

I have had a few quotes for complete strip and replacement of 90's wooden soffits/fascias: and gutters. One company uses an "over fascia" vent which is a hidden slotted strip attaching to the top of the soffit front fascia, with eaves tray above. Their soffits have NO ventilation slots...

Hi all, I’ve built a flat pack log cabin from power sheds as a workshop. The “logs” are 44mm thick and it’s actually really warm in there compared to outside. I did an insulated concrete base with 100mm PIR and am currently studding the interior so I have cavities to hide electrics behind...

We bought a B&B that the previous owner thought it was a good idea to vent 2 of 3 Guest room showers directly into the loft space. There's tiny inline fans above each shower vent and 1 metre length of flexible 100mm ducting just open at the end into the loft for 2 of the 3 showers. 1 shower is...

My mum wants me to add a layer of insulation around the outside walls of her small bungalow and clad over it to improve her damp and unhealthy living conditions inside. However I want to understand the problem and make sure her idea is the solution. The existing external cladding is wood with a...

Hi, I recently had some work done to rectify quite a few problems on my roof. I had new batons, membrane, ridge tiles, etc. Because of the problems, we were getting damp coming into one of the bedrooms in my house, specifically around a chimney. It turns out that the chimney was practically...

Hi all, 1880’s semi detached house, been here about 18 months. Last week spotted a damp patch in living room on wall that is external (backs directly onto neighbours side access pathway that is at least 1 meter higher than my ground level!) Peeled back vinyl flooring to find a side of tide...

Hi, Wondering about filling the gap (builders silicone) between the top of the outside leaf of my cotswold stone brick cavity wall where it meets the roof. It is a 5 year old traditional new build (detached) House by the way. I want to prevent small birds, insects and other possible pests...

I have candy CFTNF3518FW Integrated Smart 70/30 Fridge Freezer Today there was a puddle on the floor in front of the FF, water had gathered in the bottom of the freezer and was frozen. It seems to have been very slowly triclkling water from the back of the freeser behind the removable plastic...

Hiya, this is an external wall behind a toilet. There use to be a far bigger hole in the wall, presumably made when the soile pipe was installed. The ducting from the extracstor fan to the downstairs toilet previously use to just point vaguely in the direction to an air brick on the outer wall...

BG: Old terraced house. Have had recurrent rising damp issues since moving in many moons ago. Bubbling walls, peeling paint, black mould etc. Replaced the timber in the living room coming up to a year ago. Two of them had collapsed beneath the floor boards. During this time we aired the entire...

I'm about to make some fitted wardrobes along a 2 metre stretch of a 4m bedroom wall and want to prevent mould forming. The wardrobe doors will be solid 18mm ply and inset, so quite tight fitting. The wall behind is exterior, pretty cold, and in a weather exposed spot. I will put in a gap behind...

Hi all, Have been at my place 2 years, this winter approaching is my second winter here. Its a bungalow with converted upstairs dormer and some eaves storage above our kitchen downstairs. I noticed after getting Xmas decs out that between 1 or 2 of the roof rafters there is a small amount of...

Have brick-built barn, which has been previously converted by putting timber studding about 30cm from inner brick wall and covering with Kingspan. 2 of the rooms are at angles to the rest of the building and are much colder, both single story with vaulted ceilings. Both have huge draughts...

The living room has suspended timber floor and cross ventilation. Air brick vents front and used to be back of house in garden too. Now an extension has been attached back of house. I think the builder put in pipe ventilation extending to living room from garden. But I think these may not be...

Hi there, Thanks for opening this, and just wanted to get some advice on how to approach some condensation issue in the loft. Early December last year, we had a pretty serious condensation issue where the whole roof was dripping and the floor was pretty wet. I vaguely remember the humidity...
