About our fire stopping in Brattle
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. We close the openings listed on your schedule, using the specified sealant and detail. The enquiries we see most involve expanding foam used as fire stopping and head-of-wall gaps with no fire seal, on service gaps in risers, linear gaps at wall heads and cable penetrations. Searching for sealant specialists in Brattle? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Rural conversions around Brattle can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What the job involves on each surface
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork usually needs a different solution set by the designer.
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.

For managing agents and facilities managers
CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Questions we are asked in Brattle
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Brattle?
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.
Is Brattle too small for you to travel to?
Not at all. Brattle is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Can staff carry on working while you’re here?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Deciding what a wall or floor needs, which belongs to the designer
- Issuing fire ratings or certificates for seals
- Walls or floors that aren’t fire-resisting to begin with
If you are not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Joints and surfaces we work on

Advice
After the work
Problems stay small when the joints are checked regularly. In particular:
- Leave fire sealant to cure fully before covering it
- Arrange inspection before areas are covered up
- Include service cupboards in routine inspections
- Don’t let anyone top up a fire seal with the wrong product
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original, or a new specification from the designer.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
Penetration seals near Brattle
Central London is about 48 miles from Brattle. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail.
In a school such as Woodchurch Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified. For a building such as Parish Church of All Saints, new heating or data runs are the usual reason penetrations need sealing.

When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
