About our fire stopping in Rettendon
Most of our fire stopping work happens after the building is up. 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. We work on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and the usual reasons a site gets in touch are fire stopping installed outside its tested range and service penetrations left open after M&E works. Most enquiries from Rettendon start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For a smaller site near Rettendon, 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.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

FAQs: Rettendon
Can you work at a site such as Western Industrial Estate, by Rettendon?
Yes. Our area takes in Rettendon and its surroundings, with estates and business parks such as Western Industrial Estate included. Photos and a short description are enough for a first look.
Can you take on a job at a hospital such as Baddow Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you fire stop behind the services contractors?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see.
Will fire-rated sealant work on every penetration?
No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Do you cover Rettendon?
Yes. Sites across Rettendon are covered, and the same phone number covers every area.
Do you design or specify fire stopping?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is installing what they specify, to the product’s tested detail.
Fire stopping around Rettendon: what changes locally
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. At about 30 miles from central London, Rettendon is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.
Theatres, wards and plant rooms at sites like Baddow Hospital (4.2 miles north-west of Rettendon) all have compartment walls crossed by services. Where a unit on an estate such as Western Industrial Estate, 2.3 miles to the east of Rettendon, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

How a job runs
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. If others near Rettendon need work, visits can be combined. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Point out any areas we must not close
- Flag any permit to work we will need
- Confirm the product named in the specification

After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Brief every trade that openings they make must be sealed
- Get seals inspected before ceilings and boxing close
- File the specified details where the next contractor can find them
- Ask the designer to confirm details early on refits
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.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.

What else we do in Rettendon
What happens if it’s left?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. For buildings around smaller places like Rettendon, 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.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Fire risk assessments, a job for a competent assessor
- Construction that lacks the fire resistance the seal relies on
- Issuing fire ratings or certificates for seals
If you’re not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
What the job involves on each surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, with backing added if the detail requires it.
