Where Old Meets New
Many homes here have a flat-roof extension joined to the original tiled roof. That junction is a common leak point.
- Flashings. Mortar or old flashing where the flat roof meets the house wall cracks and lets water behind.
- Box gutters. Valleys and gutters between roof sections block with leaves and overflow.
- Different falls. The extension roof may drain towards the old house instead of away from it.

Get Waterproofing QuotesWhat Affects the Quote
- Cause of the damp. Rising damp, wind-driven rain and condensation each need a different fix and price.
- Roof junctions. Reworking flashings and gutters adds to a simple coating job.
- Plaster. Hacking off and replastering salty plaster is often the bulk of a damp quote.
- Timing. Prices and availability are easier in summer than mid-winter.
Winter Damp or Rising Damp?
- Rising damp. Low on walls, salt marks, there all year but worse in winter.
- Penetrating damp. Patches on outside walls, often higher up, that grow after a cold front.
- Condensation. Mould on cold walls and ceilings in closed rooms, worst on still winter mornings.
Ask for the cause in writing before you pay for a treatment.
Questions to Ask a Welgelegen Contractor
- Is this rising damp, rain coming through the wall or condensation?
- Will you fix the flashing at the extension, or only coat the roof?
- Which plaster will you use after damp treatment, and how long must it dry before painting?
- What is guaranteed, for how long, and in writing?
Waterproofing Welgelegen FAQs
Why does my extension leak where it meets the house?
The flashing or seal at the wall joint has usually cracked or was never properly detailed. Replacing it often fixes the leak without redoing the whole roof.
Can I paint over damp walls?
Not successfully. Paint and plaster keep failing until the source of the moisture is dealt with.
Should tiles be coated to stop leaks?
Usually not as a first step. Broken tiles, ridges and valleys are repaired first, because a coating does not fix a failed underlay or flashing.
When is the best time for damp treatment?
Any time, but walls dry faster in summer, so replastering and painting can happen sooner.
