Great Canfield: your questions answered
Can you help a landlord with a rental near Stansted Airport station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you cover smaller places like Great Canfield?
Yes. Great Canfield is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you do fire sealant around door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door, its seals and closer are for a door specialist.
Can I use normal mastic around a pipe through a fire wall?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.
How long does fire rated sealant take?
That depends on how much there is to do, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Is the work guaranteed?
Yes. Every job comes with a one-year guarantee.
How we handle fire rated sealant in Great Canfield
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. We work on flats & HMOs, linear gaps and pipe & cable gaps, and people most often call us about gaps where walls meet ceilings or slabs and door frames with gaps between frame and wall.
If you have holiday lets, a converted barn used for business or a community building near Great Canfield, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Different surfaces, different methods
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run leaving no stretch unsealed.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Tell trades working in the building that fire seals must be put back
- Check whether a sealant can be painted before decorating over it
- Never patch a fire seal with standard sealant
- Report cracked or damaged seals as soon as you notice them
Any fire seal that’s 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.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Fire doors that need new seals, closers or hardware
- Certifying a building or signing off its fire safety
- A wall that isn’t a fire-resisting element to begin with
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

Leave it or put it right?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. In a small place like Great Canfield, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

What fire rated sealant looks like in Great Canfield
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
Community buildings like Parish Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Rented homes near Stansted Airport station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
