How we handle fire stopping in Forstal
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. Each seal follows the manufacturer’s tested detail, not a rule of thumb. We work on cable penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and what we’re called in for most is snag lists that include open service penetrations and unsealed openings around new pipes and cables. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Forstal, preparation and product choice get the time they need.
For a smaller site near Forstal, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

After the work
Problems stay small when the joints are checked regularly. Specifically:
- Leave fire sealant to cure fully before covering it
- Record which product was used where
- Put resealing into every M&E and fit-out package
- Treat an open penetration as a priority repair
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
How a job runs
We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. Smaller jobs around Forstal can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- We fit the backing the detail asks for, to the stated depth.

Advice
Why deal with it now?
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. Halls, stores and units around places like Forstal may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Common questions from Forstal clients
Will you work in a care home in Forstal without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
Will you plan work around the academic year at somewhere like University for the Creative Arts?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Do you work in Scotland as well as England?
Scotland sets its own building regulations, with Technical Handbooks. Either way, we install the specified sealant to its tested detail.
Do you hold third-party fire-stopping installer certification?
No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we’re not the right fit for that package.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Owners, agents and contractors
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
General trades versus a specialist
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
When to call us in Forstal
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.
Any of the following is a good reason to get the joints checked over:
- Service penetrations left open after M&E works
- Improvised or mixed-product fire seals
- Fire-stopping items raised at inspection or handover
- Unsealed penetrations discovered above suspended ceilings
Halls and meeting rooms at places like Methodist Church Including Sunday School sometimes gain new services, and any compartment wall crossed needs the specified seal.
Before you book anyone
- Can the work be phased to keep areas open?
- What level of public liability insurance do they hold?
- Do they follow the manufacturer’s priming guidance?
- Health and safety accreditation such as CHAS
