Fire-rated sealant in Lexden, Essex
Our applicators work in Lexden on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly.
- Ordinary sealant used where a fire-rated product was needed
- Open joints along the top of partitions
- Door frames with gaps between frame and wall
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we handle fire rated sealant in Lexden
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and the gap is resealed with a product tested for that use. If you’re dealing with unsealed gaps where pipes and cables go through a wall and gaps where walls meet ceilings or slabs, we can put it right, on linear gaps, flats & HMOs and door frames alike.
If you run a pub, café, guest house or shop in or near Lexden, the washrooms and kitchen need the same attention as a big site.
We stand behind the work with a 12-month guarantee.

Fire rated sealant in Lexden: local notes
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 work to the specification you are given, installing the product to its tested details. Lexden has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
Community buildings like Church of St Leonard are part of the picture too: gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Philip Morant School and College, gaps opened by contractors for new cabling are a common finding in schools and offices. Letting a property close to Colchester station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What happens if it’s left?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. In a smaller place like Lexden, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Lexden questions
Will you come out to Lexden?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work in hotels near Lexden?
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.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
What does intumescent mean?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Lexden.
Do you carry out fire risk assessments?
No, assessment is not something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long does fire rated sealant take?
As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer, and we’ll say how long yours will take.
What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Parking around Lexden is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

How the job changes by surface
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.
Flats and HMOs
Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and the locations noted.
What sealant work cannot fix
Before you book, it’s worth knowing the limits:
- Doors that aren’t fire doors in the first place
- Walls or floors that weren’t built to resist fire
- Sign-off of the building, which sits with building control or your assessor
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.
Where we work in Lexden
- Service penetrations
- Pipe & cable gaps
- Door frames
- Plasterboard & masonry
- Linear gaps
- Flats & HMOs
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Include hidden areas like risers in routine checks
- Store the list of sealed gaps with your building paperwork
- Include fire stopping when you schedule refits
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record so the item can be closed.
