About our fire stopping in Box Hill
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. We work on cable penetrations, service gaps in risers and pipe penetrations, and what we are called in for most is fire-stopping items raised at inspection or handover and damaged fire seals in risers and voids. Most enquiries from Box Hill start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Box Hill, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Quoting for work in Box Hill
Quotes vary with the job. It mainly depends on:
- Whether the work must be split into stages
- How accessible the joints are
- Joint width, depth and condition
- Whether old sealant has to be cut out first
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
What to include in your enquiry
However big the job, the same details help:
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
- How the joints are reached, and at what height
- The asbestos register, for older buildings
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Fire stopping around Box Hill: what changes locally
There are several hotels within about 2 miles of Box Hill. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Box Hill is about 19 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.
For a building at a site such as Chesterfield Business Park, 2.3 miles to the east of Box Hill, a check of penetration seals after each fit-out is good practice. Halls and meeting rooms at places like St. Andrew's Church sometimes gain new services, and any compartment wall crossed needs the specified seal. For a school such as The Ashcombe School, penetration sealing fits best at the end of the summer works.
Box Hill is about 2 miles north-east of Dorking, in Surrey. If you’re looking for fire stopping in Box Hill, we can help, as we do across Surrey. Box Hill is one of 379 places we cover in Surrey for service penetrations. Our London page has more on work in that area (19 miles or so).

Leave it or put it right?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. For buildings around smaller places like Box Hill, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Questions about Box Hill
Can you seal around new services in a hotel near Box Hill?
Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Is Box Hill too small for you to travel to?
Not at all. Box Hill is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
How long does a typical visit take?
That varies with the scale of the job, but the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Openings that need collars, wraps, batts or boards rather than sealant
- Approving the work on behalf of building control
If in doubt, phone 01277 525 020 or email drawings and photos and we’ll say what we think.

Diagnose, treat, sign off
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Rural sites near Box Hill may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Warn occupants and staff about the work
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Different surfaces, different methods
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones usually call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork normally needs a different solution set by the designer, and we will say if that applies.
