How we handle fire stopping in Doddinghurst
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. Those on your schedule are closed with the specified product. We work on pipe penetrations, joints between fire-resisting walls and floors and cable penetrations, and the failures we are asked to look at most are unsealed openings around new pipes and cables and head-of-wall gaps with no fire seal. Searching for sealant specialists in Doddinghurst? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
A job near Doddinghurst is normally planned around one visit, so send the specification and photographs first. 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.

Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Walls or floors that aren’t fire-resisting to begin with
- Signing off or certifying a building’s fire stopping
- Large openings beyond what any sealant detail covers
If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we’ll say what we think.
Where we work in Doddinghurst

Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Don’t let anyone top up a fire seal with the wrong product
- Record which product was used where
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Report damaged or disturbed seals as soon as they’re spotted
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
Leave it or put it right?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Halls, stores and units around places like Doddinghurst 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.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

How long does a job like this take?

Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. If others near Doddinghurst need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Have the specification and drawings to hand
- Share the asbestos register for older buildings
- Warn occupants and staff about the work

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.

Fire stopping around Doddinghurst: what changes locally
Doddinghurst lies roughly 21 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Where a unit on an estate such as Hallsford Bridge Industrial Estate, which lies north-west of Doddinghurst, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. For a building such as Church of All Saints, new heating or data runs are the usual reason penetrations need sealing.
