Fire rated sealant in Horsell
We can work through a building room by room or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. We work on linear gaps, service penetrations and plasterboard & masonry, and common reasons people get in touch are unsealed gaps where pipes and cables go through a wall and holes left by a change of layout.
In a smaller place like Horsell, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
Our work is backed for twelve months.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Why deal with it now?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the work involved is often modest. Around Horsell, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

How we quote for fire rated sealant
We quote each job individually. This is what makes a difference:
- The number and length of the joints
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- How easy the joints are to reach
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
Photos help, but a description is a good start. Please mention:
- The address or postcode of the job
- Photos by email, if that is easy
- If someone has resealed it before
- The rough size of the job
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or email us.
Do you need fire rated sealant in Horsell?
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
People usually contact us when they notice one of these:
- Joints picked up in a fire-stopping survey
- Gaps filled with a product that is not fire-rated
- Unsealed gaps where pipes and cables go through a wall
- Gaps left after a refit or conversion
If you look after a church, hall or community building such as Church of St Mary the Virgin, gaps around pipes and cables are worth checking after any building work there.

FAQs for Horsell
I let a flat near Woking station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Will you come out to Horsell?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you provide details of the products used?
Yes. You get a list of where we worked and what we used for your files.
What does intumescent mean?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
Can you work in occupied buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
Where are you based?
Mr Mastic is based in Crawley. We cover Horsell and the rest of Surrey.
What fire rating will the seal have?
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.
Will you assess my building’s fire safety?
No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.
What fire rated sealant looks like in Horsell
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
For site and facilities teams at buildings such as Woking High School, gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near Woking station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Surface by surface
Door frames
Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist, and we’ll say if we spot a problem with them.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.
