Fire Rated Sealant in Grayshott
Intumescent and fire-rated sealant around gaps, frames and service penetrations for homes and businesses in Grayshott and across Surrey. Fully insured, ARBOMaster approved and guaranteed for a year.
- Joints picked up in a fire-stopping survey
- Gaps left after a refit or conversion
- Fire seals that have cracked with movement
What happens if it’s left?
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. In an older home around Grayshott, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why choose Mr Mastic in Grayshott
- Domestic, commercial and hotel work
- Anti-fungal silicone where joints get wet

It helps to know what we cannot do:
- Deciding what fire stopping a building needs

Grayshott: your questions answered
Do you work for landlords with property near Haslemere station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Can you do fire rated sealant in Grayshott?
Yes, Grayshott is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
How long does fire rated sealant take?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We’ll give you a better idea when we quote.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What affects the cost of fire rated sealant
There’s no set price list, because no two jobs are the same. What we look at:
- The product the joint needs
- The size of the job
- Mould in or behind the old joints
- How many areas need sealing
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- How we’d reach the joints
- The type of property
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, ring 0345 464 0079 or drop us an email.

When to call us in Grayshott
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Signs it’s time to call us include:
- Linear gaps at the head of walls
- Standard silicone or caulk in a fire-stopping gap
- Fire seals that have cracked with movement
- Open holes round services passing through fire walls
Schools such as Grayshott Church of England Controlled Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
Questions to ask before booking
- Whether they seal over old material or remove it
- How much experience the applicator has
- What the quote includes, VAT included or not
- How the surfaces are prepared before sealing
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Fire rated sealant around Grayshott
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 let a flat or house near Haslemere station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a church, hall or community building such as Church of St Luke, service openings in its walls need the right fire-rated sealant, as in any building.

Advice
Different surfaces, different methods
Linear gaps
A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.
Flats and HMOs
Conversions generally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.
