About our fire rated sealant in Byfleet
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. Common call-outs are for gaps around pipes and cables through fire-resisting walls and cracked or shrunken fire-rated sealant, across plasterboard & masonry, linear gaps and pipe & cable gaps.
Commercial work around a smaller place like Byfleet normally means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

FAQs for Byfleet
Do you work for landlords with property near Byfleet & New Haw station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you work for hotels and guest houses in Byfleet?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Do you come to Byfleet?
We do. Byfleet is part of the area we cover, and the service is the same as everywhere else.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.

Different surfaces, different methods
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
How we quote for fire rated sealant
You’ll get a clear quote before any work starts. It takes into account:
- The product the joint needs
- Mould in or behind the old joints
- The size of the job
- How much old sealant there is and how hard it is to remove
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
What we need to know
To make quoting easier, let us know:
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- The type of property
- Whether it has been sealed before
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, ring 0345 464 0079 or drop us an email.
Why deal with it now?
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Homes in smaller places like Byfleet can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

When something else is needed
We will not take on work that will not last, so here’s what sealant cannot put right:
- Large holes that need a different fire-stopping system
- Fire doors that need new seals, closers or hardware
- Walls or floors that weren’t built to resist fire
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Door frames
- Flats & HMOs
- Plasterboard & masonry
- Service penetrations
- Pipe & cable gaps

What else we do in Byfleet
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How the visit works
On the day, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work generally takes a few hours for a handful of gaps, and longer for a whole building. For a job in Byfleet, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Preparing for the visit
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property

Advice
Fire rated sealant around Byfleet
Byfleet has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. 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.
Rented homes near Byfleet & New Haw station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. For site and facilities teams at buildings such as St Mary's CofE Controlled Primary School, service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Church of St Mary the Virgin, service openings in its walls need the right fire-rated sealant, as in any building.
