Common questions from Bicknacre clients
Can you work on a hospital site such as Baddow Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
What happens to BS 476 references for fire stopping in Bicknacre?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do you cover Bicknacre?
Yes. We cover Bicknacre, and the simplest way to start is to call the office on 01277 525 020 or email us.
How long does a typical visit take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Fire stopping in Bicknacre
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Bicknacre and nearby. We work on cable penetrations, joints between fire-resisting walls and floors and pipe penetrations, and the failures we are asked to look at most are fire-rated sealant that has cracked or shrunk back and hidden openings found during inspections. Searching for sealant specialists in Bicknacre? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Smaller places such as Bicknacre still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Why deal with it now?
The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. One visit to deal with every failing joint makes more sense than several trips to a place like Bicknacre. Photos of every joint help us quote for the whole job.
Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Fire stopping around Bicknacre: how the place shapes the job
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. Bicknacre is about 32 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal.
In a building such as St Andrew's, any service penetration through a fire-resisting wall should be sealed to the specified detail. Hospital estates such as Baddow Hospital, 3.6 miles to the west of Bicknacre, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Schools such as Priory Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Aftercare for building managers
For the best life from the joints:
- Agree the fire-stopping specification before services go in
- Ask which product is in place before decorating
- Include service cupboards in routine inspections
- Don’t let anyone top up a fire seal with the wrong product
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.
From enquiry to sign-off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. Jobs in and around smaller places like Bicknacre are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
What we need from you
- Flag any permit to work we will need
- Send your site hours and access windows
- Agree which areas must stay open
Ask for a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

When it isn’t the sealant
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Deciding what a wall or floor needs, which belongs to the designer
- Construction that lacks the fire resistance the seal relies on
- Reviewing a building’s overall fire safety
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Surfaces we seal
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Pipe penetrations
For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
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.
General trades versus a specialist
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 where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
