About our fire stopping in Longparish
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about openings found when ceilings come down for a refit and improvised or mixed-product fire seals, across joints between fire-resisting walls and floors, pipe penetrations and service gaps in risers. Looking for mastic applicators who cover Longparish? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
For a smaller site near Longparish, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the job changes by surface
Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness.
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork typically needs a different solution set by the designer, and we will say if that applies.
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Writing the fire-stopping specification
- Approving the work on behalf of building control
- Plastic pipes whose detail calls for a collar or wrap
If you’re not sure, just call 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
What we seal
- Cable penetrations
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
What happens if it’s left?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. For buildings around smaller places like Longparish, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
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.

Where services cross fire walls in Longparish
Longparish is about 59 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail.
On a hospital site such as Andover War Memorial Hospital, 5.1 miles west of Longparish, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. For a school such as Longparish Church of England Primary School, penetration sealing fits best at the end of the summer works.
Longparish is about 5 miles east of Andover, in Hampshire. We cover commercial sites throughout Longparish, whether it’s a single job or part of a planned programme. Across Hampshire, 723 places are covered, Longparish among them. There’s a separate page for Southampton, roughly 19 miles from Longparish.
Postcode districts covered here: SP11 for service penetrations. Streets here include Mill Lane and Southside Road, and sites on any of them can send details for a fixed quote. Sites close to Longparish are covered too, including Middleton (1 mile west), Barton Stacey (2 miles south), Egypt (3 miles south-east), Sutton Scotney (3 miles south-east) and Hunton (4 miles south-east). Nearby towns on our patch include Basingstoke (13 miles east), Winchester (10 miles south), Andover (5 miles west), Chandler's Ford (14 miles south), Romsey (15 miles south) and Tadley (15 miles north-east).
What’s near Longparish
We work on buildings around The Cricketers Inn and the streets around them. Longparish’s nearest station is Whitchurch (Hampshire) station, roughly 3.5 miles north-east. Nearby you will also find Finkley Down Farm Museum (3.6 miles north-west) and Andover War Memorial Hospital (5.1 miles west). For a walk, there’s Anton Lakes and Mill Lake.
Signs you need fire stopping in Longparish
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
If one of these sounds familiar, it’s time for a closer look:
- Old intumescent sealant that has split away
- Fire seals cut back for extra cables and never reinstated
- Builders’ foam or ordinary silicone in compartment walls
- Openings found when ceilings come down for a refit
For a unit at a site such as Harewood Forest Industrial Estate, which lies south-west of Longparish, new power or data runs between office and warehouse can breach a compartment wall.
Before you book anyone
- How the joint faces will be prepared and primed
- The named product and why it was chosen
- What level of public liability insurance do they hold?
- Will failed sealant be removed rather than covered?
Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Longparish. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Questions we are asked in Longparish
How does the move away from BS 476 affect penetration seals in Longparish?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is Harewood Forest Industrial Estate, near Longparish, within your area?
Yes. We cover Longparish and the area around it, including industrial estates, business parks and retail parks such as Harewood Forest Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can you work while the building is occupied?
Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.
How much does the work cost?
We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. If others near Longparish need work, visits can be combined. You’ll have a fixed quote before work starts.
- 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.
- 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.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Explain the parking and delivery arrangements
- Send your site hours and access windows
- Clear stock, furniture or equipment away from the joints
