Questions about Ampfield
Is Ampfield too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is hospital work, at somewhere like Romsey Hospital, something you do?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will you sign off the seals for us?
No. Approval sits with the designer, principal designer or building control. We will confirm the product and detail installed, and you can tell us what other records you need at quote stage.
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. EI 60 means integrity and insulation for 60 minutes in the tested arrangement and the installation has to match the test.
What do you charge?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
Do you work in Scotland as well as England?
Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, using products tested for their end use.
How we handle fire stopping in Ampfield
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Ampfield and nearby. The enquiries we see most involve expanding foam used as fire stopping and openings left by services added after handover, across service gaps in risers, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. Facilities teams, main contractors and managing agents in Ampfield tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller places such as Ampfield still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Fire-rated sealing for Ampfield buildings
At about 67 miles from central London, Ampfield is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
Hotels such as The Potters Heron Hotel, 0.6 miles to the east of Ampfield, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Tenant changes at parks like Sleepy Hollow Business Park (to the west of Ampfield) bring new data and services, and openings through fire-resisting walls need the specified seal. In a school such as Ampfield Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified.
Ampfield is about 2 miles north-west of Chandler's Ford, in Hampshire. Ampfield sits inside our coverage and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. Ampfield is one of 723 places we cover in Hampshire for service penetrations. Southampton is covered too, around 6 miles from Ampfield.
We cover the SO51 postcode districts for service penetrations. For a building on Morleys Green, Green Pond Lane and Lower Farm Lane or nearby, we can quote for service penetrations. You’ll find Ampfield on or near the A3090, so getting applicators and materials to site is simple. Just outside Ampfield, we also work in Gosport (1 mile south-west), Knapp (1 mile north-east), Broadgate (1 mile east), Crampmoor (1 mile west) and Lower Slackstead (1 mile north). Further afield, our area takes in Winchester (6 miles north-east), Eastleigh (5 miles south-east), Fareham (15 miles south-east), Andover (14 miles north), Totton (7 miles south-west) and Hedge End (8 miles south-east).

Different surfaces, different methods
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area.
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest against the detail’s limits, and any outside it are raised with you.
On site: what to expect
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. If others near Ampfield need work, visits can be combined. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Confirm the product named in the specification
- Tell us which areas need to stay in use
- Clear stock, furniture or equipment away from the joints
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’ll arrange one.

Looking after the joints
A few simple habits keep the new joints working:
- Put resealing into every M&E and fit-out package
- Settle who seals which penetrations at the start of a project
- Arrange inspection before areas are covered up
- Keep general-purpose fillers away from compartment walls
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, so check the product data first.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Issuing fire ratings or certificates for seals
- Openings that need collars, wraps, batts or boards rather than sealant
- Fire doors, dampers or other fire safety equipment
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Where we work in Ampfield
- Service gaps in risers
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Cable penetrations
- Linear gaps at wall heads

What sets the cost
What shapes the price:
- How accessible the joints are
- Location, for remote and island sites
- Phasing around occupants
- The size and state of each joint
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
Sending details for a quote
Diagnosis starts before we arrive. Let us know:
- Clear photographs of the problem areas
- Whether the building will be occupied during the work
- Approximate linear metres or a joint schedule
- When you need the work done
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Why act early in Ampfield
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. For buildings around smaller places like Ampfield, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
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.
