Stebbing Fire Rated Sealant
Professional fire rated sealant in and around Stebbing, with every bit of old sealant taken out first.
- Seals cut through by electricians, plumbers or data installers
- Gaps around pipes and cables through fire-resisting walls

Honest limits
We will not take on work that will not last, so these are the limits:
- Construction that doesn’t provide fire resistance on its own
- Openings too large for sealant, which need batts, boards or another system
- Fire risk assessments, which need a qualified assessor
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

About our fire rated sealant in Stebbing
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. We work on pipe & cable gaps, service penetrations and plasterboard & masonry, and people most often call us about old fire sealant that has split or come away and new service routes left unsealed after building work.
If you have holiday lets, a converted barn used for business or a community building near Stebbing, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Whatever the size of the job, it’s backed by our one-year guarantee in Stebbing and across Essex.

Why it’s worth doing now in Stebbing
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Older cottages and farmhouses around Stebbing can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- Anti-fungal silicone where joints get wet
- 180+ five-star Google reviews
- Domestic, commercial and hotel work
- Arbo and Everbuild products

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Landlords, agents and businesses in Stebbing
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Do you need fire rated sealant in Stebbing?
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.
These are the problems we are asked about most:
- Damaged fire sealant left by other trades
- Gaps around pipes and cables through fire-resisting walls
- Open joints along the top of partitions
- Open gaps behind door architraves
For site and facilities teams at buildings such as Stebbing Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
Questions to ask before booking
- How much experience the applicator has
- Which sealant they’ll use, and why
- What the cure time is
- Are they insured?
What affects the quote in Stebbing
Some jobs are bigger than they look, and some smaller. The main factors:
- The product the joint needs
- The number and length of the joints
- Working hours on commercial sites
- Whether the work is at height
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.
Helping us quote
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.

Stebbing questions
Will you come out to Stebbing?
Yes, Stebbing is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is there a guarantee on fire rated sealant in Stebbing?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do you certify the fire stopping?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Stebbing.
Do you work in flats, HMOs and commercial buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.
How the visit works
At the end, we look at the finished work together. The work normally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. Somewhere as small as Stebbing, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts

What fire rated sealant looks like in Stebbing
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Community buildings like United Reformed Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.
