About our fire stopping in Boxted
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. If you have head-of-wall gaps with no fire seal and non-fire-rated filler around services, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Boxted it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a smaller site near Boxted, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or send photos by email and we will arrange a return visit.

Service penetrations in Boxted buildings
Boxted is about 53 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal. 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. Either way, we install the specified product to its tested detail.
Halls and meeting rooms at places like Church of St Peter sometimes gain new services, and any compartment wall crossed needs the specified seal. In a school such as Boxted St Peter's Church of England School, fire-rated sealant goes in around service penetrations where it is specified. Theatres, wards and plant rooms at sites like Cygnet Hospital Colchester, 2.1 miles south of Boxted, all have compartment walls crossed by services.

What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Construction that lacks the fire resistance the seal relies on
- Writing the fire-stopping specification
- Issuing fire ratings or certificates for seals
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads

After the work
Problems stay small when the joints are checked regularly. Specifically:
- Flag new cables with no seal around them
- Settle who seals which penetrations at the start of a project
- 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, so check the product data first.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
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 before sealing.
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance.
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building around Boxted, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Let us know about inductions and permits
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand

Should maintenance staff do it?
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Boxted: questions and answers
Is Boxted too far out for you?
No. Places such as Boxted are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Is Langham Barns Business Centre, near Boxted, within your area?
Yes. Estates, retail parks and business parks around Boxted, Langham Barns Business Centre among them, are all within reach. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Do you certify or sign off fire stopping?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
What do you charge?
There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.
Is sealant suitable for all service openings?
No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution, as set out by the designer.
Cost factors for service penetrations
Your fixed quote is built from the real scope. It takes account of:
- How much there is to seal
- Removal of failed or old sealant
- Location, for remote and island sites
- Induction, permit and paperwork requirements
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
What we need to price the job
Good information means a firmer quote. When you get in touch, include:
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
- The product your specification calls for
- What the building is and how it’s used
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’ll arrange a site visit if anything is unclear.
