FAQs for Longwick
Will you come out to Longwick?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Longwick in your area for fire rated sealant?
Yes. We work across London and the South East, and Longwick is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Can you tell me which gaps need fire stopping?
No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is standard sealant good enough for a fire gap?
No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service and we can apply it for you.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Fire rated sealant in Longwick, done properly
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. Typical jobs include gaps filled with a product that isn’t fire-rated and linear gaps at the head of walls, on flats & HMOs, door frames and linear gaps.
For a pub, café, guest house or shop in or near Longwick, the washrooms and kitchen need the same attention as a big site.
A one-year guarantee comes as standard.

Fire rated sealant in Longwick: local notes
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.
Managing a site like Longwick Church of England Combined School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Letting a property close to Monks Risborough station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Around Longwick
Locally, jobs take us to homes and businesses close to Princes Risborough School and The Red Lion Public House and the streets around them. The closest station to Longwick is Monks Risborough station, roughly 1.3 miles east of the centre.

What we’re called out for in Longwick
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
These are the problems we’re asked about most:
- Unsealed gaps around fire door frames
- Sealant items on a fire risk assessment action list
- Gaps filled with a product that isn’t fire-rated
- Open holes round services passing through fire walls
For buildings such as Owlswick Chapel, older buildings that have had new heating or wiring often have service gaps worth checking.
What your quote should include
- What happens if the job turns out different
- Are they insured?
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
What affects the quote in Longwick
There’s no set price list, because jobs vary so much. What we look at:
- Which sealant suits the joint
- When we can work, for business premises
- The number and length of the joints
- How many areas need sealing
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Whether it has been sealed before
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, ring 0345 464 0079 or drop us an email.
How the visit works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job usually takes anything from a few hours to several days, depending on how many gaps there are, and we tell you how long to leave it before we go. In a smaller place like Longwick, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- 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.
- We record the locations and products used for your records.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Landlord and commercial work in Longwick
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
For anyone letting property in or around Longwick, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
DIY versus a professional finish
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 fails, we can still redo it.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Doors that are not fire doors in the first place
- Walls or floors that weren’t built to resist fire
- Certifying a building or signing off its fire safety
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Where we work in Longwick
- Linear gaps
- Pipe & cable gaps
- Door frames
- Service penetrations
- Flats & HMOs
- Plasterboard & masonry
Why act early in Longwick
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. Around Longwick, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
