What is specialist replastering?
If your building has suffered from rising damp, or moisture penetrating your walls, you may need a specialist replastering service.
In order to rectify the problems caused by damp, you’ll need to remove the plaster on the affected walls or the finishing on your floors. Then you’ll need to replaster the area with specialist moisture-resistant compounds, which provide you with long-term protection against continued dampness.
It’s a technical process, but our team of experts can do it all for you.
Specialist replastering is the final step to waterproofing your home. Most damp proofing and structural waterproofing systems require this bespoke replastering in order to maintain their effectiveness.
