How we handle fire stopping in Thorncombe Street
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. Site teams most often ask us about penetration schedules that need working through and old intumescent sealant that has split away, across cable penetrations, linear gaps at wall heads and pipe penetrations. Looking for mastic applicators who cover Thorncombe Street? We have been sealing commercial buildings since 2005.
Around smaller places like Thorncombe Street, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Cost factors for service penetrations
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Access and working height
- Working within restricted access windows
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Send us:
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
- The site address and postcode
- Approximate linear metres or a joint schedule
A good quote starts with a clear picture: 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.
Diagnose, treat, sign off
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If others near Thorncombe Street need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000
- Warn occupants and staff about the work

Thorncombe Street: questions and answers
Would you work within a site like Milford Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Can you work at a site such as Godalming Business Centre, by Thorncombe Street?
Yes. We cover Thorncombe Street and the area around it, including industrial estates, business parks and retail parks such as Godalming Business Centre. Send details of the unit and the work through our quote form for a quick quote.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
How long does a job like this take?
It depends on the scope, but the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you design or specify fire stopping?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What we are called out for in Thorncombe Street
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.
Common reasons buildings call us in:
- Non-fire-rated filler around services
- Seals disturbed by maintenance and left open
- Improvised or mixed-product fire seals
- Unsealed openings around new pipes and cables
Campus buildings at universities such as University of Surrey - Manor Park Campus (to the north of Thorncombe Street) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Gaps in walls that were never built as compartment walls
- Plastic pipes whose detail calls for a collar or wrap
- Deciding what a wall or floor needs, which belongs to the designer
If you’re not sure, just call 01277 525 020 or email the details over and we will give you a straight answer.
Surfaces we seal
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Service gaps in risers
When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What the job involves on each surface
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening.
