Fire stopping across Ranmore Common
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What the job involves on each surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits, and any outside it are raised with you.
Metal pipes
Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.
Fire stopping in Ranmore Common, done properly
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on cable penetrations, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are snag lists that include open service penetrations and hidden openings found during inspections. Most enquiries from Ranmore Common start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a smaller site near Ranmore Common, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Arrange inspection before areas are covered up
- Keep product data and details in the fire safety file
- Treat an open penetration as a priority repair
- Make fire stopping part of every scope that crosses a fire-resisting wall
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there instead of being left for someone else.
How a job runs
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. For a building around Ranmore Common, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Explain the parking and delivery arrangements
- Send your site hours and access windows
- Warn occupants and staff about the work

What affects the price in Ranmore Common
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- The total length or number of joints
- Whether old sealant has to be cut out first
- Whether the work must be split into stages
- Induction, permit and paperwork requirements
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- When you need the work done
- The type of building and who uses it
- Access details, including height
- Where the site is, with the postcode
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email a schedule or drawings.
Why deal with it now?
Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small. Halls, stores and units around places like Ranmore Common may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

- Fire-rated sealant that has cracked or shrunk back

Fire-rated sealing for Ranmore Common buildings
Ranmore Common has a number of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Halls and meeting rooms at places like Church of St Barnabas sometimes gain new services, and any compartment wall crossed needs the specified seal. On estates like Chapel Lane Industrial Estate, 1 mile to the south of Ranmore Common, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Your questions answered
How does the move away from BS 476 affect penetration seals in Ranmore Common?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is Ranmore Common too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
