How we handle fire rated sealant in Crossness
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. We work on door frames, flats & HMOs and service penetrations, and people most often call us about fire stopping disturbed by later work and linear gaps at the head of walls.
In London, a commercial job often starts with access: loading bays, building rules and lifts. For a building in Crossness, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
Each job carries a 12-month guarantee, large or small.

When something else is needed
A few problems are outside what sealant work can do:
- Fire risk assessments, which need a qualified assessor
- Problems with the door itself rather than the gap around the frame
- Large holes that need a different fire-stopping system
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.
Joints and surfaces we work on
- Door frames
- Plasterboard & masonry

- Flats & HMOs
When to call us in Crossness
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
People normally contact us when they notice something like this:
- Unsealed gaps where pipes and cables go through a wall
- Joints picked up in a fire-stopping survey
- Ordinary sealant used where a fire-rated product was needed
- Old fire sealant that has split or come away
Rented homes near Abbey Wood station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
What your quote should include
- Which sealant they’ll use, and why
- The length of the guarantee
- Is VAT in the price?
- How the colour is chosen
Surface by surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.
Flats and HMOs
Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and record where they are.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ask which product was used before you paint
- Include hidden areas like risers in routine checks
- Make resealing part of every contractor’s brief
- File the fire-stopping record where your assessor can find it
Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
Fire rated sealant around Crossness
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 are given, installing the product to its tested details. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
Crossness is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a church, hall or community building such as Church of the Cross, service openings in its walls need the right fire-rated sealant, as in any building.

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
How much does fire rated sealant cost in Crossness?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.

Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.

What affects the quote in Crossness
For a quick quote, just ask. What matters most is:
- Any working-time requirements on site
- How easy the joints are to reach
- Which sealant suits the joint
- How many areas need sealing
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- The problem you’ve noticed
- Where the job is, and your postcode
- Whether it has been sealed before
- Pictures of the joints, sent by email
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A DIY attempt does not rule out a professional job. We cut it out and start again.
