Fire rated sealant for homes and businesses in Markyate
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. We work on service penetrations, door frames and flats & HMOs, and common reasons people get in touch are open holes round services passing through fire walls and gaps filled with a product that isn’t fire-rated.
In a smaller place like Markyate, 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.
You get a 12-month guarantee, the same in Markyate as everywhere else we work.

Fire rated sealant around Markyate
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 buildings such as Markyate Methodist Church, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Markyate Village School and Nursery, service openings in fire-resisting walls need checking after any refurbishment.

FAQs for Markyate
Can you do fire rated sealant in Markyate?
Yes. We work across London and the South East, and Markyate is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Will you come out to Markyate?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of gaps, and longer for a whole building from start to finish. For a job in Markyate, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

Advice
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Surface by surface
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach and we’ll flag it.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Fire doors that need new seals, closers or hardware
- Openings too large for sealant, which need batts, boards or another system
- Deciding what fire stopping a building needs
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- Door frames
- Flats & HMOs
- Service penetrations
- Pipe & cable gaps
- Linear gaps
- Plasterboard & masonry
What we are called out for in Markyate
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
If you can see any of these, it’s time to have the joints looked at:
- Door frames with gaps between frame and wall
- Joints picked up in a fire-stopping survey
- Old fire sealant that has split or come away
- Holes left by a change of layout
Rented homes near Luton Airport Parkway station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
What to look for in a quote
- How much experience the applicator has
- How hidden problems are handled
- Is VAT in the price?
- What product goes in the joint
