Fire stopping for Peasmarsh sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a single visit for a short list of penetrations, or a phased programme for a whole building. If others near Peasmarsh need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Point out any areas we must not close
- Tell us what induction or permit system the site runs
- Share the asbestos register for older buildings

About our fire stopping in Peasmarsh
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. The enquiries we see most involve fire sealant pulled out of the opening and non-fire-rated filler around services, on pipe penetrations, service gaps in risers and cable penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Peasmarsh it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Rural conversions around Peasmarsh can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Gaps in walls that were never built as compartment walls
- Deciding what a wall or floor needs, which belongs to the designer
- Signing off or certifying a building’s fire stopping
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly.

How the quote is worked out
Before we quote, we look at:
- Whether the work must be split into stages
- Quantities, in metres or numbers
- Removal of failed or old sealant
- Location, for remote and island sites
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Whether an asbestos survey exists
- Rough lengths or quantities, or drawings if you have them
- The type of building and who uses it
- When you need the work done
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
What the job involves on each surface
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.
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 first.
What we are called out for in Peasmarsh
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.
Typical triggers for a call:
- Fire-stopping items raised at inspection or handover
- Unsealed openings around new pipes and cables
- Old intumescent sealant that has split away
- Expanding foam used as fire stopping
For a unit at a site such as The Astolat Industrial Estate, under half a mile to the south-west of Peasmarsh, new power or data runs between office and warehouse can breach a compartment wall.
What your quote should include
- Who will actually carry out the work
- What the guarantee covers, and for how long
- How they’ll work around occupants
- Is the sealant right for the movement and the substrate?
Why deal with it now?
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Halls, stores and units around places like Peasmarsh may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

FAQs: Peasmarsh
Do you seal service penetrations in hotels around Peasmarsh?
Yes. We install fire-rated and intumescent sealant where it is specified. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Is Peasmarsh off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Where services cross fire walls in Peasmarsh
The area within 2 miles of Peasmarsh holds several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. At about 29 miles from central London, Peasmarsh is within reach of the capital.

At a college such as Guildford College (2.6 miles north of Peasmarsh), checking penetration seals after summer M&E works is good practice. Tenant changes at centres like Ladymead Retail Park (2.8 miles north of Peasmarsh) often mean new services through walls between units.
