How we handle fire rated sealant in Mount Pleasant
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment on buildings across Mount Pleasant. If you share the list, we can quote for the gaps that need fire-rated sealant. We work on door frames, service penetrations and flats & HMOs, and common reasons people get in touch are new service routes left unsealed after building work and open gaps behind door architraves.
In a village or hamlet like Mount Pleasant, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Store the list of sealed gaps with your building paperwork
- Keep photos of seals that will be hidden
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Plan fire stopping into any work that goes through walls or floors
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
Landlords, agents and businesses in Mount Pleasant
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Different surfaces, different methods
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each, and tell you if sealant alone isn’t the right fix.
When it is not the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Fire doors that need new seals, closers or hardware
- Deciding what fire stopping a building needs
- A wall that is not a fire-resisting element to begin with

Questions from Mount Pleasant
Can you help a landlord with a rental near Sway station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Mount Pleasant?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you provide details of the products used?
Yes. Every gap we seal is listed with the product used.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Do you certify the fire stopping?
Ratings and certificates aren’t something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What fire rated sealant looks like in Mount Pleasant
If you run a hotel, guest house or holiday let in a coastal place like Mount Pleasant, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
If you look after a building such as Priestlands School, fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Sway station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a small place like Mount Pleasant, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Advice
Why deal with it now?
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Where a wall is exposed, as many are in small places like Mount Pleasant, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
