How we handle fire stopping in Dunkirk
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. What we bring is careful installation of the specified sealant, to the maker’s guidance. Most enquiries involve unsealed openings around new pipes and cables and penetration schedules that need working through, on pipe penetrations, cable penetrations and service gaps in risers. Looking for mastic applicators who cover Dunkirk? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Smaller places such as Dunkirk 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.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Cost factors for service penetrations
The price varies from site to site. It mainly depends on:
- Which sealant the job calls for
- The total length or number of joints
- Removal of failed or old sealant
- Induction, permit and paperwork requirements
Whether it’s a single area or a whole estate, the same things set the price: 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.
What to include in your enquiry
However big the job, the same details help:
- Asbestos survey details if the building is older
- Photos of the joints, close up and from further back
- The site address and postcode
- Any dates the work must fit around
For a fixed quote, speak to us on 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.
Commercial clients in Dunkirk
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking anything from one day to a planned run of visits, depending on the number of seals and the access. For work around Dunkirk, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed
Request a quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or send details through our quote form.

Honest limits
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Openings that need collars, wraps, batts or boards rather than sealant
- Construction that lacks the fire resistance the seal relies on
- Fire risk assessments, a job for a competent assessor
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.

Dunkirk: questions and answers
Does your area include sites such as Lamberhurst Farm Industrial Estate, near Dunkirk?
Yes, sites like Lamberhurst Farm Industrial Estate are within our area, along with the rest of Dunkirk. Photos and a short description are enough for a first look.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Dunkirk?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months on every job.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
What we’re called out for in Dunkirk
Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.
Things that normally lead to an enquiry:
- Seals that don’t match their tested detail
- Unsealed joints where partitions meet the slab
- Builders’ foam or ordinary silicone in compartment walls
- Old intumescent sealant that has split away
Residences at universities like University of Kent, 3.7 miles east of Dunkirk, have compartment walls that must be resealed whenever services change.

Penetration seals near Dunkirk
For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. We install whatever has been specified, to the product’s tested detail. Dunkirk is about 48 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.
Large healthcare estates like Eastbridge Hospital of St Thomas the Martyr, 4.4 miles east of Dunkirk, change their services often, so penetration seals are worth checking after M&E work. On estates like Lamberhurst Farm Industrial Estate, which lies north of Dunkirk, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
