Fire rated sealant around Old Coulsdon
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
Old Coulsdon is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Rented homes near Coulsdon South station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Common problems we fix in Old Coulsdon
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
Any of these means the joints need attention:
- Open holes round services passing through fire walls
- Holes left by a change of layout
- Standard silicone or caulk in a fire-stopping gap
- Door frames with gaps between frame and wall
For buildings such as Church of St John the Evangelist, gaps around pipes and cables are worth checking after any building work there.

- What the quote includes, VAT included or not
- Whether you can choose the colour
- What guarantee comes with the work
Keeping the joints in good condition
Looking after new joints is easy:
- Photograph sealed gaps before they’re covered up
- Include hidden areas like risers in routine checks
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Get damaged fire seals looked at promptly
Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
Leave it or put it right?
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.

Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
What we do, step by step

For most jobs that takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy.

- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
