Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Common problems we fix in Ashton
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.
Common reasons buildings call us in:
- Snag lists that include open service penetrations
- Unsealed penetrations discovered above suspended ceilings
- Improvised or mixed-product fire seals
- Unsealed openings around new pipes and cables
In a building such as Church of St Peter, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Proof of insurance
- The terms of the workmanship guarantee
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
About our fire stopping in Ashton
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. We close the openings listed on your schedule, using the specified sealant and detail. We work on small duct penetrations where the tested detail allows, cable penetrations and pipe penetrations, and the failures we’re asked to look at most are seals disturbed by maintenance and left open and open linear gaps along the top of fire-resisting walls. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Ashton is the same: the right product in a properly prepared joint.
Around smaller places like Ashton, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or email us and we will arrange a return visit.

Fire-rated sealing for Ashton buildings
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Ashton is about 61 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product.
Schools such as Bishops Waltham Infant School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. On a site such as Swanmore Business Park, 2.2 miles south-east of Ashton, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.
Ashton is about 5 miles north-east of Hedge End, in Hampshire. Commercial clients in Ashton can call on us for service penetrations. Ashton is one of 723 places we cover in Hampshire for service penetrations. There’s a separate page for Southampton, about 8 miles away.

Other services in Ashton
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Ashton can sit alongside others in a wider programme.
How the quote is worked out
To price the job, we consider:
- Whether old sealant has to be cut out first
- The total length or number of joints
- The size and state of each joint
- Phasing around occupants
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Details that help us quote
The more we know, the firmer the quote. When you get in touch, include:
- Whether an asbestos survey exists
- Any dates the work must fit around
- Drawings or a marked-up plan, if available
- The postcode of the building
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.
FAQs: Ashton
Does your area include sites such as Swanmore Business Park, near Ashton?
Yes. Estates, retail parks and business parks around Ashton, Swanmore Business Park among them, are all within reach. A few photos and the unit address let us price the work.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Ashton?
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.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
Can the sealant be colour-matched?
That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
What the job involves on each surface
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, with no gaps along the run.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance along with any permits your site needs.
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Ask which product is in place before decorating
- File the specified details where the next contractor can find them
- Arrange inspection before areas are covered up
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts.
On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. Smaller jobs around Ashton can be grouped with others nearby. You will have a fixed quote before work starts.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Point out parking and an unloading spot
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000
