We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
How we handle fire rated sealant in Colliers End
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. If you have unsealed gaps around fire door frames and unsealed gaps where pipes and cables go through a wall, we can put it right, on pipe & cable gaps, service penetrations and door frames alike.
For holiday lets, converted business premises or a community building near Colliers End, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When something else is needed
We’ll always be straight with you, so here’s what new sealant won’t do:
- Big openings where sealant alone is not the tested solution
- Problems with the door itself rather than the gap around the frame
- Construction that does not provide fire resistance on its own
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

What else we do in Colliers End
When to call us in Colliers End
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
If you can see any of these, it’s time to have the joints looked at:
- Gaps left after a refit or conversion
- Standard silicone or caulk in a fire-stopping gap
- Unsealed gaps where pipes and cables go through a wall
- Open gaps behind door architraves
If you look after a church, hall or community building such as St Mary's, service openings in its walls need the right fire-rated sealant, as in any building.
Before you book anyone
- Which sealant they’ll use, and why
- How the joint is cleaned and prepared
- What insurance they hold
- How the colour is chosen
Leave it or put it right?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job that does not depend on other work. Older cottages and farmhouses around Colliers End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
What you get with us
- One-year guarantee on every job

Commercial buildings in Colliers End
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Letting a property close to Ware station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Managing a site like Ralph Sadleir Middle School? Then fire-stopping around service openings should be restored whenever new services go in.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

- Access and height
