About our fire rated sealant in River
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We work on door frames, plasterboard & masonry and pipe & cable gaps, and the jobs we see most are standard silicone or caulk in a fire-stopping gap and fire seals that have cracked with movement.
Community buildings, schools and small businesses around places like River have washrooms and kitchens that see a lot of use. Their sealant and fire-rated joints are as important as those in any bigger building.
There’s a 12-month guarantee on every job.

What affects the cost of fire rated sealant
There’s no set price list. What we look at:
- The product the joint needs
- When we can work, for business premises
- Whether the work is at height
- Mould in or behind the old joints
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.
What to tell us for a quote
To make quoting easier, please include:
- Pictures of the joints, sent by email
- Roughly how big the job is
- The problem you’ve noticed
- Any access issues, like height or stairs
Every job is quoted individually, so start by telling us what you need. Just phone 0345 464 0079 or email us with the details and send photos if you have them.
Surface by surface
Door frames
Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail and we flag any that need another system.
Leave it or put it right?
A quick fill with any sealant to hand isn’t 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. Around River, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Commercial buildings in River
If you run a hotel, guest house or holiday let in a coastal place like River, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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.
For buildings such as Church of St Peter, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Kearsney station, any gap left by new services in shared walls should be closed with a fire-rated product.

Do you need fire rated sealant in River?
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.
Any of these means the joints need attention:
- Gaps around pipes and cables through fire-resisting walls
- Standard silicone or caulk in a fire-stopping gap
- Fire stopping disturbed by later work
- Door frames with gaps between frame and wall
Schools such as River Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
What your quote should include
- Which sealant they’ll use, and why

How the visit works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. Parking around River is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- On commercial sites, let us know about site rules
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
How to get a quote
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep pictures of seals that will be hidden
- Flag any open gap you spot round a pipe or cable
- Make resealing part of every contractor’s brief
- Keep the record of products and locations with your fire safety documents
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
