Fire rated sealant for homes and businesses in Caversham Heights
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. We work on plasterboard & masonry, service penetrations and pipe & cable gaps, and common reasons people get in touch are seals cut through by electricians, plumbers or data installers and new service routes left unsealed after building work.
Commercial work around a smaller place like Caversham Heights generally means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Fire rated sealant in Caversham Heights: local notes
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. There are hotels and other places to stay in and around Caversham Heights. Hotel work can be planned room by room, with out-of-hours working where needed.
For site and facilities teams at buildings such as Caversham Primary School, fire-stopping around service openings should be restored whenever new services go in.

Surface by surface
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for each gap size.
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
What we’re called out for in Caversham Heights
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.
These are the problems we are asked about most:
- Gaps filled with a product that is not fire-rated
- Open gaps behind door architraves
- Joints picked up in a fire-stopping survey
- Holes left by a change of layout
If you look after a church, hall or community building such as St. Andrew's Church, service openings in its walls need the right fire-rated sealant, as in any building.
Questions to ask before booking
- Whether VAT is included
- How long the guarantee is
- Whether you can choose the colour
- What product goes in the joint

How we quote for fire rated sealant
Your quote is based on your job. We take into account:
- Working hours on commercial sites
- Whether the work is at height
- The number of rooms or windows
- Which sealant suits the joint
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
- Where the property is
- The problem you’ve noticed
Every job is quoted individually. Just ring 0345 464 0079 or email us with the details, and pictures are welcome.
What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Construction that does not provide fire resistance on its own
- Large holes that need a different fire-stopping system
- Certifying a building or signing off its fire safety
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.

What happens on the day
On the day, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work normally takes a few hours for a handful of gaps, and longer for a whole building. In a smaller place like Caversham Heights, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- 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.
How to prepare
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

Advice
Why deal with it now?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Around Caversham Heights, 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.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

No. We work from the specification you give us and install to the manufacturer’s details.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What does intumescent mean?
An intumescent sealant expands when it gets hot to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
