How much does fire rated sealant cost in Otterbourne?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.

About our fire rated sealant in Otterbourne
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That is the part we focus on, one gap at a time. We work on linear gaps, service penetrations and plasterboard & masonry, and common reasons people get in touch are fire stopping disturbed by later work and unsealed gaps around fire door frames.
Somewhere as small as Otterbourne, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
Our work is backed for twelve months, in Otterbourne and everywhere else we cover.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the 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.
For landlords and businesses
Housing providers, facilities teams and property managers book us too in Otterbourne and across Hampshire. We can quote a run of properties together, and we are fully insured for the work.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
When to call us in Otterbourne
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
Most people get in touch when they notice one of these:
- Open holes round services passing through fire walls
- Gaps where walls meet ceilings or slabs
- Holes left by a change of layout
- Unsealed gaps around fire door frames
If you let a flat or house near Shawford station, any gap left by new services in shared walls should be closed with a fire-rated product.
Questions to ask before booking
- How the surfaces are prepared before sealing
- Which sealant they’ll use, and why
- Is VAT in the price?
- What the cure time is
Looking after it afterwards
To keep the joints looking good and working properly:
- Ask every contractor to reseal any fire stopping they disturb
- Take photos of fire stopping before ceilings or boxing go back
- Plan fire stopping into any work that goes through walls or floors
- Get damaged fire seals looked at promptly
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.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Construction that doesn’t provide fire resistance on its own
- Sign-off of the building, which sits with building control or your assessor
- Big openings where sealant alone is not the tested solution
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Otterbourne, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used.
Before we arrive
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Advice
Fire rated sealant around Otterbourne
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a building such as Otterbourne Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Church of St Matthew are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Why act early in Otterbourne
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. In a small place like Otterbourne, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
