Fire stopping for commercial buildings in Hill Grove
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you are dealing with seals that don’t match their tested detail and service penetrations left open after M&E works, we can help, on joints between fire-resisting walls and floors, linear gaps at wall heads and small duct penetrations where the tested detail allows alike. A specialist sealant contractor works differently from a general builder: on jobs in Hill Grove, preparation and product choice get the time they need.
For a smaller site near Hill Grove, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
A 12-month guarantee applies to all our work in Hampshire. Should something we installed fail, ring 01277 525 020 or email the details over and we will come back to it.

Surface by surface
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers, and we work within it.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Service penetrations in Hill Grove buildings
Fire stopping of openings and penetrations in England falls under 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. What we install is set by the specification, and it goes in to the tested detail. At about 61 miles from central London, Hill Grove is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
Halls and meeting rooms at places like Church of St Barnabas sometimes gain new services, and any compartment wall crossed needs the specified seal. On a site such as Waltham Business Park, 0.8 miles south-west of Hill Grove, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Wherever services are added at a hospital such as Knowle Hospital (4.4 miles south of Hill Grove) the compartment line has to be made good with the specified product.
Hill Grove is about 6 miles east of Hedge End, in Hampshire. Commercial clients in Hill Grove use us for work on service penetrations. Across Hampshire, 723 places are covered, Hill Grove among them. There’s a separate page for Southampton, about 10 miles away.

How a job runs
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a building around Hill Grove, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- 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.
- 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
- Arrange parking or a loading space
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints

Owners, agents and contractors
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Hill Grove can sit alongside others in a wider programme across Hampshire.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Openings that need collars, wraps, batts or boards rather than sealant
- Walls or floors that aren’t fire-resisting to begin with
- Fire doors, dampers or other fire safety equipment
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

- Pipe penetrations

- Linear gaps at wall heads

Common questions from Hill Grove clients
Is Hill Grove off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Is hospital work, at somewhere like Knowle Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
