Different surfaces, different methods
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. We follow the manufacturer’s tested detail for each, and tell you if sealant alone is not the right fix.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Brent Pelham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Tell us about any water getting in
- Mention any parking rules near the property
- Move anything stored near the joints

What we are called out for in Brent Pelham
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.
If you can see any of these, it’s time to have the joints looked at:
- Sealant items on a fire risk assessment action list
- Standard silicone or caulk in a fire-stopping gap
- Door frames with gaps between frame and wall
- Fire seals that have cracked with movement
In and around Brent Pelham, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.
What your quote should include
- Which colour the sealant will be
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
- What the cure time is
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Where a wall is exposed, as many are in small places like Brent Pelham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.

Brent Pelham: your questions answered
Do you cover smaller places like Brent Pelham?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Brent Pelham for fire rated sealant?
Yes. Our work covers London and the South East, and Brent Pelham is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Sign-off of the building, which sits with building control or your assessor
- Big openings where sealant alone is not the tested solution
- Fire doors that need new seals, closers or hardware
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Check whether a sealant can be painted before decorating over it
- Keep general-purpose foam and caulk away from fire-stopping gaps
- File the fire-stopping record where your assessor can find it
- Include fire stopping when you schedule refits
Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
