Fire rated sealant in Hook, done properly
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. Common call-outs are for door frames with gaps between frame and wall and ordinary sealant used where a fire-rated product was needed, on flats & HMOs, pipe & cable gaps and service penetrations.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Hook, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Workplaces and buildings in Hook
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you let a flat or house near Chessington North station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Hook is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as St Paul's CofE Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Questions from Hook
Is Hook in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Hook is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Chessington North station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Is it messy?
We keep the work tidy. We protect what’s around the joints.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do you certify the fire stopping?
We do not issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer.

What the job involves on each surface
Flats and HMOs
Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and the locations noted.
Door frames
Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Why it’s worth doing now in Hook
Squirting in whichever sealant is nearest doesn’t make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Hook, the repair is bigger than a sealant job.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why us?
- We leave the area clean and tidy
- ARBOMaster approved applicator
- Homes, businesses and hotels
- Fully insured
What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. In Hook, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
