About our fire stopping in Lamarsh
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you have unsealed openings around new pipes and cables and non-fire-rated filler around services, we can put it right, whatever the surface. Looking for mastic applicators who cover Lamarsh? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Aftercare for building managers
To get the most from the new sealant:
- Treat an open penetration as a priority repair
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Record which product was used where
- Get seals inspected before ceilings and boxing close
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned.

What else we do in Lamarsh
Building owners, agents and FMs in Lamarsh
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Do you need fire stopping in Lamarsh?
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
Things that normally lead to an enquiry:
- Open linear gaps along the top of fire-resisting walls
- Openings found when ceilings come down for a refit
- Service penetrations left open after M&E works
- Old intumescent sealant that has split away
On a hospital site such as Halstead Hospital (5.5 miles south-west of Lamarsh), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
What your quote should include
- Which product they’ll use, and why it suits the joint
- Whether primer will be used where the manufacturer specifies it
- Will CSCS-carded applicators be on site?
- Health and safety accreditation such as CHAS
Cost factors for service penetrations
These are the things that shape the price:
- Phasing around occupants
- Backing rod, priming and other preparation
- Site requirements such as inductions and permits
- Any access equipment needed
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- A wide shot and a close-up of the area
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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.
Fire-rated sealing for Lamarsh buildings
Central London is about 49 miles from Lamarsh. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
In a building such as Church of the Holy Innocents, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Questions about Lamarsh
What happens to BS 476 references for fire stopping in Lamarsh?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is Lamarsh off your patch?
Not at all. Lamarsh is within our area. 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 seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Are you insured?
Yes. We are fully insured, including public liability cover.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
