Hobbs Cross questions
Is fire rated sealant in Hobbs Cross guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you do fire rated sealant in Hobbs Cross?
Yes. We work across London and the South East, and Hobbs Cross is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Tell us how the building is used and we’ll plan around it.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Do you do fire sealant around door frames?
Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How to look after the new joints
To keep the joints looking good and working properly:
- Never patch a fire seal with standard sealant
- Store the list of sealed gaps with your building paperwork
- Don’t paint over fire sealant until it has cured
- Photograph sealed gaps before they’re covered up
Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
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We do not publish a price list. The quote depends on:
- Mould in or behind the old joints
- Any working-time requirements on site
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the property is
- Whether it has been sealed before
- How we’d reach the joints
- What’s wrong with the joints now
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
How it works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Hobbs Cross, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Any non-fire-rated filler is removed and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

How the job changes by surface
Door frames
Frame gaps are usually hidden behind the architrave. We seal any open gap to the product’s tested details so the architrave can be refitted.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
What fire rated sealant looks like in Hobbs Cross
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 work to the specification you’re given, installing the product to its tested details.
For buildings such as Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as St John's Church of England Voluntary Controlled School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant will not put right:
- Openings too large for sealant, which need batts, boards or another system
- Fire doors that need new seals, closers or hardware
- Deciding what fire stopping a building needs
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

Why act early in Hobbs Cross
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Older cottages and farmhouses around Hobbs Cross can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before work begins.
