Fire stopping for commercial buildings in Petersfield
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Petersfield. If you are dealing with hidden openings found during inspections and open linear gaps along the top of fire-resisting walls, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Petersfield is the same: the right product in a properly prepared joint.
In a town like Petersfield, penetration seals normally need attention after other trades have been through. Checking after M&E works is good practice, and we’ll seal what’s found where fire-rated sealant is the specified product.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Looking after the joints
Once the work is signed off, these steps help:
- Agree the fire-stopping specification before services go in
- Have penetrations checked while they can still be seen
- Include service cupboards in routine inspections
- File the specified details where the next contractor can find them
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.
How the job changes by surface
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we will never swap a specified collar for sealant.
Small ducts
We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.
What sets the cost
The price varies from site to site. Expect it to depend on:
- Removal of failed or old sealant
- Distance, for remote addresses
- Working within restricted access windows
- The product specified
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- Access details, including height
- The type of building and who uses it
- Whether an asbestos survey exists
- Photos of the joints, close up and from further back

General trades versus a specialist
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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Compartments and services around Petersfield
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail. At about 50 miles from central London, Petersfield is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Schools such as Petersfield Infant School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. For a unit at a site such as Upper Adhurst Industrial Park, 1.9 miles north-east of Petersfield, new power or data runs between office and warehouse can breach a compartment wall. Hotels like The Red Lion Hotel, less than half a mile south-east of Petersfield, are refurbished in phases, and each phase can open up compartment walls.
Petersfield is about 10 miles north of Havant, in Hampshire. Our applicators travel to Petersfield for work on service penetrations, handled exactly as we handle every other area. Across Hampshire, 723 places are covered, including Petersfield. For work in that direction, see our Portsmouth page (15 miles or so).
Commercial sites across GU31 and GU32 are covered. We cover commercial and managed buildings on High Street, Station Road and London Road.

If your building is just outside Petersfield, we cover Sheet (1 mile north-east), Steep (1 mile north), Stroud (2 miles west), Steep Marsh (2 miles north) and Langrish (3 miles west). Nearby towns on our patch include Havant (10 miles south), Horndean (7 miles south-west), Alton (10 miles north), Waterlooville (9 miles south-west), Purbrook (10 miles south-west) and Bordon (8 miles north-east).

What happens if it’s left?
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

How a job runs
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If you have more than one building in Petersfield, they can often be done on the same visit, with one quote covering them. Tell us when the building is open and we’ll plan to suit.
- We read the specification, drawings or penetration schedule you send.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000

Questions we’re asked in Petersfield
Does your area include sites such as Upper Adhurst Industrial Park, near Petersfield?
Yes, sites like Upper Adhurst Industrial Park are within our area, along with the rest of Petersfield. Send details of the unit and the work through our quote form for a quick quote.
What does the BS 476 change mean for fire-rated sealant in Petersfield?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure.
Can staff carry on working while you’re here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Do you work in Petersfield?
Yes. We take on work across Petersfield, and the same phone number covers every area.
