the mortar below the concrete sill is damaged and loose. But, we have seal all the window frame and no water will go in between the sill and fram. You mean the sill has to change.

Yes. It is old wood fram cover with thin metal sheet. When last year doing window caulking, some of the bottum fram were found rotten, but window now is sealed well.

Stain under windows. After winter, the bricks under windows have white powder (efflorescence) as shown on the photo. When I bought the house last year and some contracts told me it was because the window seals had a lot cracks and the water enter the wall through the cracks. So, I redo...

Thanks for suggestion. What is the reason to slide out a peice of plywood and what should I look for?

Thank you for your explaination. I have checked the thermal insulation in attic are dry and has no water mark. The roof boards are dry. But, because the slope of the roof, the bottom of the roof is hard to reach and also filled with thermal insulation material. I did not check it and I will try...

Do you mean a water insulation and twenty feet horizontally? What is the water insulation over the wall? If the wall is under my roof, does it have water insulation? My house layers are as following: inside wall, air gap,black paper, wood fram, black paper, air gap, outside brick wall...

Thank you for reply. Recently, I found one of my two downspouts was blocked at the bottom. I don't know if this is the reason to make water enter my brickwork around my chimney. The chimney is in the middle of my two downspouts.
