Fire stopping for commercial buildings in Tipner
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, call 01277 525 020 or email us 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. We work on linear gaps at wall heads, service gaps in risers and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are fire seals cut back for extra cables and never reinstated and builders’ foam or ordinary silicone in compartment walls. A specialist sealant contractor works differently from a general builder: in Tipner, that means joint design, primers and backing rod as standard.
In places the size of Tipner, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sets the cost
We price every job individually. The main factors are:
- How much existing material needs removing
- Working within restricted access windows
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Anything awkward about access or site hours
- Clear photographs of the problem areas
- The type of building and who uses it
- The postcode of the building
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Work in places the size of Tipner is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- For older buildings, check the asbestos register before work
- Explain the parking and delivery arrangements
- Agree which areas must stay open

Surface by surface
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area.
What else we do in Tipner
Questions we are asked in Tipner
Do you work on fire-rated sealing in hotels in Tipner?
Yes, where fire-rated sealant is the specified product. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
How does the move away from BS 476 affect penetration seals in Tipner?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
How do I request a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Service penetrations in Tipner buildings
Central London is about 64 miles from Tipner. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. Tipner has plenty of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
At a healthcare site like Queen Alexandra Hospital, 2.3 miles north of Tipner, new services through compartment walls are a constant, and each needs the specified seal. At a university such as University of Portsmouth - North Zone, 1.5 miles to the south of Tipner, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Workshops and IT rooms at colleges like Portsmouth College, 2 miles to the east of Tipner, are re-serviced often, leaving penetrations to seal.
Tipner is about 1 mile north-west of Portsmouth, in Portsmouth. We send applicators to Tipner for service penetrations. Tipner is one of 19 places we cover in Portsmouth for service penetrations.

We also cover North End (1 mile east), Rudmore (1 mile south-east), Portsmouth (1 mile south-east), Landport (1 mile south) and Hilsea (1 mile north-east) for service penetrations.

Maintenance after handover
Regular inspection catches problems early. In particular:
- Foam or ordinary sealant is never a fire-seal repair
- Have penetrations checked while they can still be seen
- Treat an open penetration as a priority repair
- Ask which product is in place before decorating
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
