Fire rated sealant in Westcroft
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate. If you have gaps around pipes and cables through fire-resisting walls and linear gaps at the head of walls, we can help, on linear gaps, service penetrations and pipe & cable gaps alike.
For a pub, café, guest house or shop in or near Westcroft, its washrooms and kitchen need the same sealant care as any big building.
Every job is covered by our 12-month guarantee, wherever you are in Milton Keynes.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Different surfaces, different methods
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both.
Flats and HMOs
Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and record where they are.
What fire rated sealant looks like in Westcroft
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’re given, installing the product to its tested details.
Rented homes near Milton Keynes Central station change hands often, and 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 Giles's Church, older buildings that have had new heating or wiring often have service gaps worth checking.

- Assessing a building’s fire safety

- Issuing a fire rating or certificate for a building

Questions from Westcroft
I let a flat near Milton Keynes Central station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Is Westcroft within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Where do you work from?
We work from Crawley. Our applicators cover Westcroft, along with the rest of our area.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
How long does the job take?
Most jobs take from a few hours to a few days, depending on the number of gaps and the access, including preparation and clearing up. We will confirm how long when we quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access, and the area is left clean. For a job in Westcroft, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- Clear the area around the work
- Mention any tricky access
- Tell us if parking is tricky

What we’re called out for in Westcroft
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
If you can see any of these, it’s time to have the joints looked at:
- Fire seals that have cracked with movement
- Gaps left after a refit or conversion
- Ordinary sealant used where a fire-rated product was needed
- Gaps where walls meet ceilings or slabs
Schools such as Oxley Park Academy are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
What to look for in a quote

Leave it or put it right?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Around Westcroft, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
