Fire rated sealant in Box Hill
Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Common call-outs are for gaps around pipes and cables through fire-resisting walls and fire stopping disturbed by later work, across linear gaps, flats & HMOs and pipe & cable gaps.
In a village or hamlet like Box Hill, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
There’s a 12-month guarantee on every job, large or small.

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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
When to call us in Box Hill
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
Look out for these signs:
- Open joints along the top of partitions
- Holes left by a change of layout
- Standard silicone or caulk in a fire-stopping gap
- Door frames with gaps between frame and wall
Managing a site like The Ashcombe School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.
What your quote should include
- The length of the guarantee
- How long to leave it before use
- Which sealant they’ll use, and why
- Whether they seal over old material or remove it
Workplaces and buildings in Box Hill
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, 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.
Community buildings like St. Andrew's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Letting a property close to Betchworth station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

For landlords and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
What we can’t put right
Before you book, it’s worth knowing the limits:
- Issuing a fire rating or certificate for a building
- Walls or floors that weren’t built to resist fire
- Big openings where sealant alone isn’t the tested solution
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.
Surfaces we seal

Why it’s worth doing now in Box Hill
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In a small place like Box Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

How the visit works
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before we start. The work normally takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Box Hill, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises

Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before any work starts.
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.
