How we handle fire stopping in North Street
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in. If you are dealing with seals that don’t match their tested detail and unsealed joints where partitions meet the slab, we can help, on service gaps in risers, pipe penetrations and linear gaps at wall heads alike. Searching for sealant specialists in North Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
A job near North Street is normally planned around one visit, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Have penetrations checked while they can still be seen
- Ask the designer to confirm details early on refits
- Record which product was used where
- Make fire stopping part of every scope that crosses a fire-resisting wall
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. For work around North Street, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- 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.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Tell us what induction or permit system the site runs
- Confirm the product named in the specification

Your questions answered
How does the move away from BS 476 affect penetration seals in North Street?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you seal around new services in a hotel near North Street?
Yes. We install fire-rated and intumescent sealant where it is specified. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
What happens if it’s left?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. 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. Older rural buildings around North Street move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
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 you will have a fixed figure to work with.

For managing agents and facilities managers
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in North Street can sit alongside others in a wider programme.
What sets the cost
Quotes vary with the job. Expect it to depend on:
- How much existing material needs removing
- Joint width, depth and condition
- Quantities, in metres or numbers
- Working within restricted access windows
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- The site address and postcode
- Drawings or a marked-up plan, if available
- The asbestos register, for older buildings
- Whether the building will be occupied during the work
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

What the job involves on each surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables, so we check before sealing.
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest so we know it sits within the tested range.
Compartment walls and floors in North Street
At about 45 miles from central London, North Street 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. The area within 2 miles of North Street holds several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
For a school such as Sheldwich Primary School, penetration sealing fits best at the end of the summer works. Older community buildings such as Church of St James that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Hotels such as Premier Inn Faversham Hotel, 1.3 miles north of North Street, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
North Street is about 2 miles south of Faversham, in Kent. Anywhere in ME13, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. North Street is one of 931 places in Kent on our list. There’s a separate page for London, about 45 miles away.
