How do I repair brick leakage on pebble dashing wall?

Anonymous user 03/03/2024 - 2.43 PM

I believe I have brick leakage causing water to get in to the house. The water is coming in to the spare room from the back of the house. The damage patches are scattered under the window seal and at window level. I initially thought the issue was down to a leak in the guttering since having the guttering changed it’s not rained strongly. Now that it has the damp patches are appearing once again. Back ground info- I have pebble dashing on the exterior wall. I also have double glazing which I believe was installed at a later date as there are gaps in the pebble dashing in places which have been filled with what looks like clear silicon. I believe the causes may be down to: 1)The gaps near the windows have a weak spot allowing water to come in - how could I check if this is the case? Or 2) There is a single or several weak spot/s in the pebble dashing – Is there any way to check for weak spots on the pebble dashing? What would be the best solution to resolve this issue myself & professionally?

Are you a tradesperson and able to answer this question?

Generally speaking, render or pebble dash will, over time, speparate from the brick. It usually cracks at the same time, so water gets trapped between the wall and the pebbledash. Eventually, these sections fall off. If your house has solid brick walls, or if the leak is by windows, you are guaranteed to get damp patches on the inside wall. The only correct cure is is replace the loose sections of pebbledash, you can do find these by tapping the surface, in the same way as you can detect loose plaster on an inside wall. You will also find that the loose pebbledash is in the same position as the damp patch on the inside. Silicone repair of any cracks will work for a while but is not a cure. Make sure all windows are well sealed by a flexible sealant. You can tell if the house has solid brick walls by looking for end-bricks on any wall, scattered amongst the bricks laid in the normal way. If it has these, it has solid brick walls.

Sounds like someones been doing a bit of bodging, silcone over the cracks. Go over the pebble dashing, give it a good tapping to see if any of the pebble dash/render has blown, if this is the case then it needs redoing. Check silicone joints between windows and wall.

short and sweet of it is if its blown it might need hacking off and redoing or you might get away with cutting out the blown bits and patching them . but it never looks the same as the original . when the window company put the windows in t hey should have dashed on to the frame and cleand off with a brush to seal them hoped this helped
