Weyhill Fire Rated Sealant
Fire-stopping gaps in Weyhill need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Joints picked up in a fire-stopping survey

The process
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. The job normally takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Weyhill, access is generally the main thing to plan. 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.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your files.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky

Advice
Fire rated sealant for homes and businesses in Weyhill
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. Typical jobs include new service routes left unsealed after building work and joints picked up in a fire-stopping survey, across service penetrations, door frames and flats & HMOs.
In a village or hamlet like Weyhill, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What else we do in Weyhill
Commercial buildings in Weyhill
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, 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 landlords with property near Andover station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Church of St Michael and All Angels are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

When it is not the sealant
It helps to know what we cannot do too:
- Openings too large for sealant, which need batts, boards or another system
- Certifying a building or signing off its fire safety
- Walls or floors that weren’t built to resist fire
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Why act early in Weyhill
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. Where a wall is exposed, as many are in small places like Weyhill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Why us?
- An ARBOMaster approved applicator
- Anti-fungal sanitary silicone in wet areas

Weyhill questions
Will you come out to Weyhill?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Andover station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you certify the fire stopping?
Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.
How long does fire rated sealant take?
A typical job takes from a few hours to a few days, depending on the number of gaps and the access. We will confirm how long when we quote.
Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Is there a guarantee?
Yes. All our work carries a one-year guarantee.
Do you carry out fire risk assessments?
No, assessment isn’t something we do. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.
What does intumescent mean?
An intumescent sealant expands when it gets hot, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Different surfaces, different methods
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service against the product’s tested range.
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Do not paint over fire sealant until it has cured
- Plan fire stopping into any work that goes through walls or floors
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Store the list of sealed gaps with your building paperwork
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
What affects the quote in Weyhill
You’ll get a clear quote before we start. It’s based on:
- Whether old sealant or filler has to be cut out
- The product the joint needs
- The number and length of the joints
- Access and height
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
When you call or email, these details help:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- The address or postcode of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
