How the visit works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. In a small place like Swallowfield, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- 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
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions

Advice
Fire rated sealant for homes and businesses in Swallowfield
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. 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 door frames with gaps between frame and wall and damaged fire sealant left by other trades, on service penetrations, pipe & cable gaps and linear gaps.
Work in a small place like Swallowfield is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.
Every job is covered by our one-year guarantee, wherever you are in West Berkshire.

FAQs for Swallowfield
Can you help a landlord with a rental near Mortimer station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you cover Swallowfield for fire rated sealant?
Yes. Our work covers London and the South East, and Swallowfield is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.
How do I get a quote for fire rated sealant in Swallowfield?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available and agree one before work begins.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you tell me which gaps need fire stopping?
No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask every contractor to reseal any fire stopping they disturb
- Store the list of sealed gaps with your building paperwork
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Check risers, ceiling voids and cupboards during building checks
Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
What happens if it’s left?
For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. Older cottages and farmhouses around Swallowfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
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. We take all of that into account in your quote.

- One-year guarantee on every job
- We never seal over old sealant

What fire rated sealant looks like in Swallowfield
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’re given, installing the product to its tested details.
If you look after a building such as Lambs Lane Primary School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of All Saints, gaps around pipes and cables are worth checking after any building work there.

Surface by surface
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.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
Common problems we fix in Swallowfield
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
Any of these means the joints need attention:
- Standard silicone or caulk in a fire-stopping gap
- Linear gaps at the head of walls
- Gaps left after a refit or conversion
- Unsealed gaps around fire door frames
Rented homes near Mortimer station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Issuing a fire rating or certificate for a building
- Assessing a building’s fire safety
- Openings too large for sealant, which need batts, boards or another system
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
