Chimney Rendering in Lisburn
Rendering, repointing and weatherproofing chimney stacks — the most exposed masonry on any house.
Lisburn property owners come to us for chimney rendering for one of two reasons: something has failed, or the house looks tired.
Across Antrim, Victorian brick terraces, harled cottages and postwar estates dominates, and driving rain and dash render failure on exposed elevations is what we are called out to most often.
The area sees wet with strong Atlantic and Irish Sea exposure, which is the single biggest factor in how long any render lasts here. Dash render is close to universal on northern irish housing, and matching existing dash is the most common requirement on repair work.
When chimney rendering is the right call. Choose chimney rendering where a stack is spalling, the pointing has failed, or damp is showing in upstairs rooms near a chimney breast.

FAQs
Chimney Rendering in Lisburn
Why is my chimney causing damp?
Water enters through failed flaunching, cracked render, open pointing or defective flashings, then runs down inside the flue and shows as staining on a chimney breast, often on the floor below.
What is flaunching?
The mortar fillet that beds the chimney pots into the top of the stack and sheds water off it. It cracks and fails with age and is a very common leak point.
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
