Photos, a specification or a quick description of the joints is enough to start a fixed quote.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Keep general-purpose fillers away from compartment walls
- Check risers and ceiling voids after each round of works
- Ask which product is in place before decorating
- File the specified details where the next contractor can find them
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there, not months later.

How a job runs
Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. If neighbouring businesses or buildings around Fratton need work too, visits can be combined. Tell us your site hours and we will plan around them.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- For older buildings, check the asbestos register before work
- Point out parking and an unloading spot
- Warn occupants and staff about the work
Ask for a quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Fratton: questions and answers
Do you work in occupied care homes around Fratton?
Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.
Is Fratton off your patch?
No. Places such as Fratton are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Which standards are fire seals tested to?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested.
Do the same rules apply to fire stopping in Scotland?
Scotland sets its own building regulations, with Technical Handbooks. Wherever the site is, our work follows the specification and the tested detail.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Will you sign off the seals for us?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.
Common problems we fix in Fratton
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
Site and facilities staff are often the first to spot these:
- Builders’ foam or ordinary silicone in compartment walls
- Fire-rated sealant that has cracked or shrunk back
- Penetration schedules that need working through
- Fire stopping installed outside its tested range
For a hospital such as St James Hospital, 1.2 miles east of Fratton, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.
Before you book anyone
- The named product and why it was chosen
- Who will actually carry out the work
- Are they CHAS accredited or on Constructionline?
- What level of public liability insurance do they hold?
How the job changes by surface
Plastic pipes
Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough, and we won’t substitute it for a specified collar.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.
Fire stopping around Fratton: how the place shapes the job
The area within 2 miles of Fratton holds a good number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
Hotels such as Eastfield Hotel, 0.9 miles south-east of Fratton, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. For a unit at a site such as The Bridge Shopping Centre (under half a mile south-west of Fratton), any new service through a fire-resisting wall should be sealed to the tested detail.
Fratton is about 1 mile south-east of Portsmouth, in Portsmouth. Commercial clients in Fratton use us for work on service penetrations, as part of our coverage of Portsmouth. Across Portsmouth, 19 places are covered, Fratton among them.
Anyone looking for fire stopping in PO1, PO4 and PO3 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

We also cover Kingston (1 mile north-east), Portsmouth (1 mile north-west), Landport (1 mile west), Baffins (1 mile north-east) and Copnor (1 mile north-east) for service penetrations.

Local landmarks in Fratton

For a walk, there’s Milton Locks and Portsdown Hill.
Doing it in-house
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Walls or floors that aren’t fire-resisting to begin with
- Large openings beyond what any sealant detail covers
- Issuing fire ratings or certificates for seals
If you are not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer.
