Hey there So our extension has finally got to the point where we're opening it up to the rest of the house. As part of this, we've removed a set of double uPVC patio doors that were installed pretty poorly, and have been left with an opening that's splayed on the inside from the old window...

Hi all. I really need help determining whether a damp issue is the result of rising damp or of an acute leak. I’ve had different views from different specialists with vested interests. I’ve taken up the conservatory floor as suspected it was an issue with the drainage pipe that runs underneath...

I’ve been dealing with cold walls in a couple of bedrooms due to having two external walls, which causes cold areas and has led to issues with condensation and mould. This is something I’ve always experienced with the property, even after living here for over 10 years. I’ve involved the council...

We moved into our house around 3 years ago and the house is around 8 years old. In the last 6 months we started to get damp in the bottom corners of the windows. Then over a short period of time the window sil became completely blown on one side and we also experienced some damp patches on the...

I live in an old Victorian house. The loft in the kitchen has been removed to make the room taller. Old chimney breast has also been removed with only a bit of it remaining to support the chimney stack outside that remained intact. I've been having a number of leaks over the past couple of...

I wonder if someone can help me? My 1970 property was fitted with cavity insulation which it shouldn’t have. I was getting large damp areas so had it removed last year. Recently I’ve noticed I’m getting random damp patches in my property. Above 1st floor skirting boards, random “blobs” below...

Hello! Looking for a bit of advice. We're currently house hunting and have found something that ticks the boxes at a good price for the area. However, the render on the property clearly has seen better days and will need replacing. The sellers claim they had the render done around 10years...

Good Evening, Looking for some help from some of you far more educated people than I. We've recently had the floor leveled because it wasn't suitable for vinyl in its previous state. Now we've had it leveled we've got a new problem where its dried perfectly in mostly all areas apart from the...

Just looking for advice. 1930s semi detached suspended timber flaws although I think there may be some concrete on top within the kitchen area. Terrible at DIY, but I at least want to diagnose it yourself so I can try and get appropriate solutions. Found a tidal mark on an internal wall in...
