Fire rated sealant for homes and businesses in Spellbrook

We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. If you are dealing with holes left by a change of layout and open holes round services passing through fire walls, we can help.

What we can’t put right
In fairness, some problems need a different trade:
- Deciding what fire stopping a building needs
- Big openings where sealant alone isn’t the tested solution
- Problems with the door itself rather than the gap around the frame
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

How the job changes by surface
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail, and we will tell you.
Door frames
Frame gaps are normally hidden behind the architrave. We seal any open gap to the product’s tested details before the trim goes back.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Look in service cupboards and ceiling voids from time to time
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Include fire stopping when you schedule refits
- Keep the record of products and locations with your fire safety documents
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
How we quote for fire rated sealant
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The type of sealant required
- Any mould that needs treating
- Whether the work is at height
- How many areas need sealing
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you are ready, call 0345 464 0079 or send us an email.
The process
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes from a few hours to a few days, depending on the number of gaps and the access in most cases. In a small place like Spellbrook, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height

Fire rated sealant in Spellbrook: local notes
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.
For buildings such as Church of St Mary the Virgin, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Spellbrook CofE Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Letting a property close to Sawbridgeworth station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Your questions about fire rated sealant in Spellbrook
Can you do fire rated sealant in Spellbrook?
Yes. Our work covers London and the South East, and Spellbrook is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Sawbridgeworth station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Are you insured?
Yes, we are fully insured for domestic and commercial work.
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. Removing the old sealant completely is the only lasting way.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
Can I do it myself?
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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
