County Down has a mix of buildings, from purpose-built blocks to converted houses and commercial premises. We tailor the programme to the building, not the other way round.
Pads, linings and hidden protection

Questions
Do you provide intumescent strips and smoke seals across County Down?
Yes. We cover all of County Down, including Bangor and Newtownards. Surveys and written quotes are free.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
How long do seals last?
It depends on use and care. Seals on busy doors wear faster. Regular inspections will show when they need replacing.
