Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. For work around Boarhunt, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Let us know about inductions and permits
- For older buildings, check the asbestos register before work
- Tell staff and tenants when we’ll be in

Fire stopping in Boarhunt
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you are dealing with fire sealant pulled out of the opening and snag lists that include open service penetrations, we can put it right, on linear gaps at wall heads, pipe penetrations and joints between fire-resisting walls and floors alike. Whoever orders the work in Boarhunt, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Boarhunt, 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.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Questions we’re asked in Boarhunt
Can you take on a job at a hospital such as Knowle Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Boarhunt?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
Do you cover Boarhunt?
Yes. Boarhunt is in our area and the rest of Hampshire, within our coverage of Greater London, South East England and Scotland. To discuss a job, call the office on 01277 525 020 or send photos by email.
What will the job cost?
Each job is quoted on its own details. For yours, call 01277 525 020 or email the details over with a description of the work.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Site staff or a sealant specialist?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Compartment walls and floors in Boarhunt
At about 63 miles from central London, Boarhunt is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.
For a site team at a college like Fareham College, which lies south-west of Boarhunt, fire-rated sealing is best scheduled after the summer works. For a building such as Church of St Nicholas, new heating or data runs are the usual reason penetrations need sealing. Holiday works at schools like Cams Hill School often leave service openings to seal before pupils return.

Surface by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest so we know it sits within the tested range, and any that don’t are flagged.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail.
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Ask the designer to confirm details early on refits
- Ask which product is in place before decorating
- Don’t let anyone top up a fire seal with the wrong product
- Make fire stopping part of every scope that crosses a fire-resisting wall
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Boarhunt can sit alongside others in a wider programme across Hampshire.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Gaps in walls that were never built as compartment walls
- Approving the work on behalf of building control
- Openings that need collars, wraps, batts or boards rather than sealant
If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think before you book.
