How to Stop Water Ingress Through External Walls – Leeds
Water getting in through external walls can cause damp, mould and damage. Common causes include cracks, failed pointing, leaking gutters and ground water. Here's how to approach the problem and what we can do to fix it in Leeds.
Fix & Patch Leeds is roofing-first for leak source control, with secondary internal repairs for water damage to walls, floors and ceilings where needed.
Step-by-step
Find where the water is getting in – look for damp patches, staining or mould on internal walls. They often correspond to external defects, high ground level or leaking gutters.
Check the outside – cracks in render or brickwork, missing or damaged pointing, and gaps around windows or doors let in rain. We can seal cracks and carry out external crack and seal repairs.
Look at gutters and downpipes – water running down the wall from a blocked or leaking gutter is a very common cause. Fix the gutter first.
Consider ground level – if the ground outside is above the damp course or piled against the wall, moisture can be driven in. Improving drainage and lowering the level may be needed.
Do not just treat the inside – tanking or internal coatings can trap moisture. Fix the source on the outside where possible.
Get a professional assessment. We identify the cause and carry out external crack and seal repairs, and advise on gutters and drainage where needed, across Leeds.
Common mistakes
- ⚠ Painting or sealing the inside without fixing the external cause can trap moisture and make the problem worse.
- ⚠ Large structural cracks or serious damp may need a full survey – we can advise.
