Fire stopping for Hydestile sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Why deal with it now?
Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Around Hydestile, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Fire stopping in Hydestile, done properly
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. If you have penetration schedules that need working through and head-of-wall gaps with no fire seal, we can put it right. Most enquiries from Hydestile start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
For a smaller site near Hydestile, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Keeping the joints sound
For the best life from the joints:
- Have penetrations checked while they can still be seen
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Don’t let anyone top up a fire seal with the wrong product
- Settle who seals which penetrations at the start of a project
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
FAQs: Hydestile
Is Hydestile off your patch?
Not at all. Hydestile is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
What happens to BS 476 references for fire stopping in Hydestile?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months on every job.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Hydestile need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Flag any permit to work we’ll need
- Tell staff and tenants when we’ll be in
- Have the specification and drawings to hand
Quotes
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Construction that lacks the fire resistance the seal relies on
- Openings that need collars, wraps, batts or boards rather than sealant
- Approving the work on behalf of building control
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly.
Joints and surfaces we work on
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
