Fire rated sealant in Islip
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. Common call-outs are for gaps flagged on a fire risk assessment and fire stopping disturbed by later work, on pipe & cable gaps, service penetrations and plasterboard & masonry.
In a village or hamlet like Islip, 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.
Each job carries a 12-month guarantee.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What the job involves on each surface
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. We follow the manufacturer’s tested detail for each.
Flats and HMOs
Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance.
What we’re called out for in Islip
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
Most people get in touch when they notice something like this:
- Gaps left after a refit or conversion
- Fire seals that have cracked with movement
- Sealant items on a fire risk assessment action list
- Open gaps behind door architraves
Schools such as Dr South's Church of England Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

Questions from Islip
Is Islip within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Islip station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Is there a guarantee?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Is standard sealant good enough for a fire gap?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
How long does the job take?
It depends on the size of the job, but most jobs take from a few hours to a few days, depending on the number of gaps and the access. We will tell you when we quote.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Landlords, agents and businesses in Islip
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Islip, 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.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- 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
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
Getting a quote
Getting a quote is simple: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we will take it from there.

Why deal with it now?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. In a small place like Islip, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask a few questions first.
Why choose Mr Mastic in Islip
- We’re fully insured
- Every job guaranteed for a year
- Approved under the ARBOMaster scheme
- Old sealant always removed completely

Workplaces and buildings in Islip
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 work to the specification you are given, installing the product to its tested details.
Community buildings like St Nicholas' Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Islip station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
