Signs you need fire stopping in Hartley Mauditt
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Typical triggers for a call:
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed openings around new pipes and cables
- Openings found when ceilings come down for a refit
- Fire-rated sealant that has cracked or shrunk back
Industrial units on estates such as Southlands Industrial Park, 2 miles to the south-east of Hartley Mauditt, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

How we handle fire stopping in Hartley Mauditt
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow. We work on small duct penetrations where the tested detail allows, service gaps in risers and joints between fire-resisting walls and floors, and the failures we are asked to look at most are fire-stopping items raised at inspection or handover and hidden openings found during inspections. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Hartley Mauditt it comes down to the same thing: the right product in a properly prepared joint.
For a smaller site near Hartley Mauditt, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Work we carry out in Hampshire comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or use the quote form and we’ll come back to it.

From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Hartley Mauditt, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Make sure the joints can be reached
- Tell us what induction or permit system the site runs
- Send any specification or drawings in advance

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Should maintenance staff do it?
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 easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Fire stopping in Hartley Mauditt: the local picture
Central London is about 45 miles from Hartley Mauditt. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. 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.

What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Deciding what a wall or floor needs, which belongs to the designer
- Construction that lacks the fire resistance the seal relies on
- Plastic pipes whose detail calls for a collar or wrap
Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly.
Surfaces we seal
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
What the job involves on each surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables.
Metal pipes
Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.
