For managing agents and facilities managers
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, with each stage agreed with your site contact.
Fire stopping for commercial buildings in Friday Hill
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal. We work on cable penetrations, pipe penetrations and linear gaps at wall heads, and the usual reasons a site gets in touch are openings found when ceilings come down for a refit and old intumescent sealant that has split away. One point of contact handles commercial sealant work in Friday Hill from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Why deal with it now?
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. In Friday Hill, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

How a job runs
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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.
- 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
- For older buildings, check the asbestos register before work
- Let building users know which areas are affected
- Move anything stored against the joints
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Advice
Cost factors for service penetrations
To price the job, we consider:
- How accessible the joints are
- Removal of failed or old sealant
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Drawings or a marked-up plan, if available
- Asbestos survey details if the building is older
- How the joints are reached, and at what height
- When you need the work done
Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. If you have questions first, phone 01277 525 020 or email the details over.
Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Check risers and ceiling voids after each round of works
- Keep product data and details in the fire safety file
- Check with the data sheet before painting over fire sealant
- Keep general-purpose fillers away from compartment walls
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.
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, not months later.

Your questions answered
What does the BS 476 change mean for fire-rated sealant in Friday Hill?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Will you plan work around the academic year at somewhere like University of Portsmouth Walthamstow Campus?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Service penetrations in Friday Hill buildings
With tenants changing and fit-outs following, London buildings see service routes altered again and again. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements. A 2-mile radius around Friday Hill takes in several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
For a hotel such as The Castle Hotel, 1 mile south-east of Friday Hill, penetration seals are worth checking after any refit or services upgrade. Large healthcare estates like The Holly Private Hospital, 1.1 miles east of Friday Hill, change their services often, so penetration seals are worth checking after M&E work. At a college such as Sir George Monoux College, which lies south-west of Friday Hill, checking penetration seals after summer M&E works is good practice.

Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
