How we handle fire rated sealant in Streat
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over. If you’re dealing with fire stopping disturbed by later work and open gaps behind door architraves, we can help, on flats & HMOs, door frames and service penetrations alike.
Work in a small place like Streat is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Surface by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes from a few hours to a few days, depending on the number of gaps and the access, and the area is left clean. Somewhere as small as Streat, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.

Commercial buildings in Streat
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.
Rented homes near Plumpton station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Streat Church, gaps around pipes and cables are worth checking after any building work there.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Photograph sealed gaps before they’re covered up
- Allow for resealing whenever new services are run
- Get damaged fire seals looked at promptly
- Check whether a sealant can be painted before decorating over it
Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
When to call us in Streat
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.
The problems people normally mention when they call include:
- New service routes left unsealed after building work
- Fire seals that have cracked with movement
- Damaged fire sealant left by other trades
- Gaps around pipes and cables through fire-resisting walls
If you look after a building such as Plumpton Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Streat questions
Is Streat in your area for fire rated sealant?
Yes, Streat is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Do you cover smaller places like Streat?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you provide details of the products used?
Yes. Every gap we seal is listed with the product used, so you have it on file.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
What does intumescent mean?
An intumescent sealant expands when it gets hot to help seal the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
