Fire stopping in Marlow Common
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Ask which product is in place before decorating
- Brief every trade that openings they make must be sealed
- Record which product was used where
- Treat an open penetration as a priority repair
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
How we handle fire stopping in Marlow Common
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. Most enquiries involve expanding foam used as fire stopping and fire seals cut back for extra cables and never reinstated, across cable penetrations, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows. Searching for sealant specialists in Marlow Common? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
A job near Marlow Common is usually planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

What the job involves on each surface
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, with backing added if the detail requires it.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.
What sealant work can’t fix
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Issuing fire ratings or certificates for seals
- Writing the fire-stopping specification
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Surfaces we seal
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Linear gaps at wall heads
- Pipe penetrations
How a job runs
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Marlow Common need work, visits can be combined. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- 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.
- 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Let building users know which areas are affected
- Tell us which areas need to stay in use
- Make sure the joints can be reached
Getting a fixed quote
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Penetration seals near Marlow Common
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. We install whatever has been specified, to the product’s tested detail. The area within 2 miles of Marlow Common 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.
Schools such as Spinfield School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
