Fire stopping in Keyhaven
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
How we handle fire stopping in Keyhaven
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, give us a call on 01277 525 020 or email the details over with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. Site teams most often ask us about seals that don’t match their tested detail and non-fire-rated filler around services, on cable penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows. A single leaking joint is often how a building in Keyhaven first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Keyhaven, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common questions from Keyhaven clients
Do you seal service penetrations in hotels around Keyhaven?
Yes, to the specification and the product’s tested detail. Each seal follows the tested detail, and rooms are done in turn.
What happens to BS 476 references for fire stopping in Keyhaven?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
What sets the cost
To price the job, we consider:
- How much existing material needs removing
- The total length or number of joints
- Any access equipment needed
- The product specified
Pricing service penetrations depends on quantities, condition and access. Call for a quote.
What to include in your enquiry
Whether it’s one area or a whole building, these details speed things up:
- Drawings or a marked-up plan, if available
- The asbestos register, for older buildings
- The postcode of the building
- When you need the work done
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to give us a call on 01277 525 020 or use the quote form with what you know.
Compartment walls and floors in Keyhaven
The 2 miles around Keyhaven include two care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. We install fire-rated sealant to the tested detail where it is specified. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Theatres, wards and plant rooms at sites like Lymington New Forest Hospital (to the north of Keyhaven) all have compartment walls crossed by services. For a school such as Milford-on-Sea Church of England Primary School, penetration sealing fits best at the end of the summer works. Hotels like Milford House Hotel, 0.9 miles west of Keyhaven, are refurbished in phases, and each phase can open up compartment walls.

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Look above ceilings when tiles are lifted for other jobs
- Keep general-purpose fillers away from compartment walls
- Get seals inspected before ceilings and boxing close
- Treat an open penetration as a priority repair
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small.

Why act early in Keyhaven
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Halls, stores and units around places like Keyhaven may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
