How the job changes by surface
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it.
Fire rated sealant in Aldworth
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you have ordinary sealant used where a fire-rated product was needed and new service routes left unsealed after building work, we can put it right, on service penetrations, flats & HMOs and door frames alike.
Somewhere as small as Aldworth, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

Commercial buildings in Aldworth
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 work to the specification you are given, installing the product to its tested details.
For landlords with property near Goring & Streatley station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as St Mary's church, older buildings that have had new heating or wiring often have service gaps worth checking.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, 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 fails, we can still redo it.
What we cannot put right
We will always be straight with you, so here’s what new sealant won’t do:
- Doors that aren’t fire doors in the first place
- Walls or floors that weren’t built to resist fire
- Assessing a building’s fire safety
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.
Joints and surfaces we work on
- Flats & HMOs
- Linear gaps
- Plasterboard & masonry
- Door frames
- Pipe & cable gaps
- Service penetrations
Common problems we fix in Aldworth
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.
Keep an eye out for these signs:
- Cracked or shrunken fire-rated sealant
- Open holes round services passing through fire walls
- Holes left by a change of layout
- Gaps flagged on a fire risk assessment
Schools such as The Downs School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
Questions to ask before you book
- Which sealant they’ll use, and why
- When the joint can take water or movement
- What happens if the job turns out different
- How much experience the applicator has
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Take pictures of fire stopping before ceilings or boxing go back
- Look in service cupboards and ceiling voids from time to time
- Include fire stopping when you schedule refits
- Report cracked or damaged seals as soon as you notice them
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.
What happens if it’s left?
Squirting in whichever sealant is nearest does not make a fire seal. 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 Aldworth can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Why book with us
- A 12-month guarantee on all work
- Approved under the ARBOMaster scheme
- Domestic, commercial and hotel work
- Old sealant always removed completely
How it works
At the end, we look at the finished work together. The visit itself normally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. For a village or hamlet like Aldworth, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- 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.
- Locations and products are noted so you have them on file.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

Common questions in Aldworth
Do you cover smaller places like Aldworth?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Goring & Streatley station?
Yes. We work for landlords and agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
What’s the difference between intumescent and fire-rated sealant?
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.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Aldworth.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.
