When something else is needed
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Signing off or certifying a building’s fire stopping
- Construction that lacks the fire resistance the seal relies on
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

How we handle fire stopping in High Halstow
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on cable penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we are called in for most is openings left by services added after handover and fire-rated sealant that has cracked or shrunk back. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in High Halstow is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Rural conversions around High Halstow can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Common questions from High Halstow clients
Can you take on a job at a hospital such as Medway Maritime Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is High Halstow off your patch?
Not at all. High Halstow is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Which standards are fire seals tested to?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months on every job.
Will you write the fire-stopping specification?
No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it, and tell you if a detail needs another product.

Do you need fire stopping in High Halstow?
Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.
Clients typically get in touch after noticing one or more of the following:
- Hidden openings found during inspections
- Improvised or mixed-product fire seals
- Open linear gaps along the top of fire-resisting walls
- Service penetrations left open after M&E works
Wherever services are added at a hospital such as Medway Maritime Hospital, 5 miles south of High Halstow, the compartment line has to be made good with the specified product.

Owners, agents and contractors
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Surface by surface
Metal pipes
Heat travels along metal pipework, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.
Small ducts
Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.
How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. If others near High Halstow need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Why act early in High Halstow
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these and the building feels the difference. Around High Halstow, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
