I live in a 1950's house which does have a few damp issues upstairs in the bedrooms. Generally mold grows on the external walls in the corners and on the celling at the near this external wall. The celling slops down towards the external walls. Before anyone talks about mold prevention, I have...

Hello, I am renovating my 1950s bungalow with a suspended timber floor. As you can see in the photo I've stripped the floors down to the joists, with a composition of external cavity walls, timber joists, a small sleeper wall, and air vents. I'm shortly looking to get started putting everything...

Hi everyone! We get a lot of condensation so had a PIV fitted in the loft a couple of years back. It has improved condensation on the windows a bit but does make the upstairs absolutely freezing (particularly over the past week). Thus, I'm no longer convinced that flooding the house with...

Recently had a cellar survey to fix general dampness (humidity around 75%) in a victorian terraced house. Floor has been properly tanked but walls haven' and the main source of dampness is the front where there is also no easy route for air input. The advice was to install a PIV. I just haven't...

Hi All, Does anyone have experience with this type of single room heat recovery units? Getting a lot of condensation in the bedrooms and seen these advertised. Retrofitting a full MVHR would be extremely difficult and expensive. We're in a flat roofed bungalow so not interested in a simple...

Hello there! Could anyone tell me what is the unobstructed distance between a fire collar and another element? Planning to install a PIV unit, running a PVC pipe straight from the rear inlet to a fire-rated wall. I need to install a fire collar behind the unit, but I was wondering what's the...

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...

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...
