Fire stopping for businesses in Lockerley
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Leave fire sealant to cure fully before covering it
- Flag new cables with no seal around them
- Foam or ordinary sealant is never a fire-seal repair
- Keep product data and details in the fire safety file
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned.
About our fire stopping in Lockerley
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. 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. We work on cable penetrations, linear gaps at wall heads and service gaps in risers, and the failures we’re asked to look at most are service penetrations left open after M&E works and builders’ foam or ordinary silicone in compartment walls. Facilities teams, main contractors and managing agents in Lockerley tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Barn and farm-building conversions near places like Lockerley often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Rural sites near Lockerley may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Preparing the site
- Make sure the joints can be reached
- Let us know about inductions and permits
- For older buildings, check the asbestos register before work

What else we do in Lockerley
Compartments and services around Lockerley
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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.
At a healthcare site like Romsey Community Hospital, which lies south-east of Lockerley, new services through compartment walls are a constant, and each needs the specified seal. For a building at a site such as Home Farm Business Centre, which lies north of Lockerley, a check of penetration seals after each fit-out is good practice. In a school such as Lockerley Church of England Endowed Primary School, fire-rated sealant goes in around service penetrations where it is specified.
Lockerley is about 5 miles north-west of Romsey, in Hampshire. We send applicators to Lockerley for service penetrations. Lockerley is one of 723 places in Hampshire on our list. There’s a separate page for Southampton, about 11 miles away.

What the job involves on each surface
Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits.
Common questions from Lockerley clients
Do you cover business parks and estates near Lockerley, such as Home Farm Business Centre?
Yes. We cover Lockerley and the area around it, including industrial estates, business parks and retail parks such as Home Farm Business Centre. Photos and a short description are enough for a first look.
What does the BS 476 change mean for fire-rated sealant in Lockerley?
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 CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Can staff carry on working while you are here?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
Can weather delay the job?
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. Internal work is far less affected.
What do you charge?
We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.
What happens if it’s left?
Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable. For buildings around smaller places like Lockerley, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
