condensation

A local builder has installed insulation into the sloping ceilings of the top floor of our house. The old ceilings have been removed, and Recticel Eurothane installed between the rafters to within 25mm or less (at the edges, less where underlay sags) of the roofing felt. There is then insulation...

Good afternoon everyone! I am a first time buyer and just received the home-buyer report, and there is a section in it that makes me a little worried. To paraphrase, the felt in the area above the recently refitted bathroom is ripped. There is no dampness present at the time of the survey, but...

Happy New Year everyone. Hoping some damp experts out there can help me out with this one. My property has damp under my bay window. My first thought was condensation, as it is probably the coldest wall in the room, the heating has been on a lot over winter and there is usually a sofa in the bay...

Hi all, I've just done my first flat roof and I've left noggins to pick up the Fascia's where the joists run parallel to the wall. The joists overhang at the front also for the fascia. The brickwork is two course higher on the outside so I could have a smaller fascia board by the time the warm...

Hi all, I am sure a few of us have this problem at this time of year. I have had condensation before but I must admit it is the worst it has been this year. I have read all of the guides and general advice - one of which is to keep the loft hatch closed. However as a temporary fix would it...

Hello, I'm having an extension built. The wall is made up of an inner block leaf, an insulation layer (60mm ecotherm), a cavity, and an outer block leaf, with 25mm of external render on top. The cavity was supposed to be 50mm wide but the builder made it narrower (approx 25mm). He insists that...

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...

I live in a top floor flat and the building has a flat roof. The kitchen hood and bathroom extractor fan flues both go straight up through the roof. Last year around November water started dripping down the outside of both the kitchen hood flue (soaking wooden cabinets) and from where the...

I'm putting central heating into a flat which previously had storage heaters. I found evidence of poor ventilation, with black mould build-up most pronounced in the bedrooms. I suspect this is due to a lack of trickle vents in the double glazing. The floor is concrete and the walls are cavity...

I'm looking for advice. I have an old 1930's kitchen, single brick outer wall two sides. It gets cold in the winter and when cooking I get condensation. I'm starting to get a damp smell in the room. I do have an under cabinet fan heater in the room to take the chill off, and I only have a...

Installing 90mm by 180mm (150mm equivalent) flat channel duct work for kitchen hood extractor fan. The exit is vertical and the majority of the run will be covered by plasterboard. I will need some way of removing condensation however all the 150 traps I've found are round. Is there a way to...

Hi all, So I got a builder to build me an outbuilding. I use it for a gym. It has a power rack in it and my gym plates. It also has my Mrs sofa from her old property. From what I gather I had 14x12ft concrete base and 2.5m height building. It has 2 French doors. Zero ventilation except for...

Have had some problems with water coming in through ceiling in room adjoining next door property. Part of chimney had been removed previously so it now sits above part of the room. Had new roof, chimney had the works done to it, even had some insulation boards put on chimney in loft to prevent...

We have built an extension and had the base built for us ~ the usual layers of hardcore, sand, DPC, rigid insulation, more DPC and poured concrete. Because we want a 'traditional' timber floor, we allowed for joists and floorboards. At last inspection BCO said we needed air-bricks to ventilate...

Hi Guys I wonder if you can help/advise. We are currently going through the process of a Part Exchange with Barratt homes. They had 2 valuers come out and value our property. They have reported back that there is some damp to the rear of the property, so Barratt have made us a part exchange...
