Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- File the specified details where the next contractor can find them
- Put resealing into every M&E and fit-out package
- Settle who seals which penetrations at the start of a project
- Get seals inspected before ceilings and boxing close
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.
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.
Fire stopping in Lunsford
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, and raise it with you if it falls outside. Site teams most often ask us about fire seals cut back for extra cables and never reinstated and old intumescent sealant that has split away, on joints between fire-resisting walls and floors, pipe penetrations and service gaps in risers. Searching for sealant specialists in Lunsford? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Converted and extended buildings around places like Lunsford can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What the job involves on each surface
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers.
Cables and cable bundles
New data and power cables are the most common breach we see. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
Do you need fire stopping in Lunsford?
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
Any of the following is a good reason to get the joints checked over:
- Fire sealant pulled out of the opening
- Service penetrations left open after M&E works
- Seals disturbed by maintenance and left open
- Builders’ foam or ordinary silicone in compartment walls
Campus buildings at universities such as University for the Creative Arts - Maidstone (3.7 miles south-east of Lunsford) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

- What site paperwork they can supply
- Their public liability cover
- Whether primer will be used where the manufacturer specifies it

Common questions from Lunsford clients
Is a hospital such as Maidstone Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work around term dates at a campus such as University for the Creative Arts - Maidstone?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Do you design or specify fire stopping?
No, we don’t design fire stopping. Once you have a specification, we can price and install the sealant elements of it, and tell you if a detail needs another product.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Fire-rated sealing for Lunsford buildings
Lunsford is about 26 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
For a building such as Church of the Holy Trinity, new heating or data runs are the usual reason penetrations need sealing. At a healthcare site like Maidstone Hospital, 3.2 miles to the south-east of Lunsford, new services through compartment walls are a constant, and each needs the specified seal.
Lunsford is about 5 miles north-west of Maidstone, in Kent. Anywhere in ME20, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Kent coverage takes in 931 places. Sites around London have their own page, about 26 miles away.

Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. If neighbouring businesses or buildings around Lunsford need work too, visits can be combined. Tell us your site hours and we will plan around them.
- We read the specification, drawings or penetration schedule you send.
- 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.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Point out parking and an unloading spot
- Warn occupants and staff about the work
- Send your site hours and access windows
