North Warnborough: questions and answers
Is North Warnborough too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as Murrell Green Business Park, near North Warnborough?
Yes, sites like Murrell Green Business Park are within our area, along with the rest of North Warnborough. Photos and a short description are enough for a first look.
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, because fresh silicone will not bond with aged silicone.
Do you approve fire stopping for building control?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How we handle fire stopping in North Warnborough
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. The enquiries we see most involve seals that don’t match their tested detail and seals disturbed by maintenance and left open, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and linear gaps at wall heads. Whether you call it commercial sealant work, mastic application or joint sealing, in North Warnborough it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A job near North Warnborough is usually planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Agree the fire-stopping specification before services go in
- Arrange inspection before areas are covered up
- Record which product was used where
- Check risers and ceiling voids after each round of works
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there instead of being left for someone else.
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Smaller jobs around North Warnborough can be grouped with others nearby. You’ll have a fixed quote before work starts.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- 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.
What we need from you
- Agree which areas must stay open
- Send asbestos survey details if the building is pre-2000
- Confirm the product named in the specification

Where services cross fire walls in North Warnborough
For England, the fire stopping of penetrations is dealt with in 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. North Warnborough is about 41 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.
For a school such as Robert May's School, penetration sealing fits best at the end of the summer works. For a hotel such as The George Hotel, 0.6 miles south-east of North Warnborough, penetration seals are worth checking after any refit or services upgrade. On a hospital site such as Fleet Community Hospital, which lies north-east of North Warnborough, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
North Warnborough is about 5 miles west of Fleet, in Hampshire. Anywhere in RG29, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 723 places across Hampshire fall within our area, North Warnborough among them.

If you need fire stopping in RG29, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Whitewater Road, Queens Road and New Road are within our area for service penetrations. Just outside North Warnborough, we also work in Odiham (1 mile south-east), Warnborough Green (1 mile north-west), Greywell (1 mile west), Broad Oak (1 mile east) and Hook Common (2 miles north-west). Bigger towns within reach include Basingstoke (6 miles west), Farnborough (8 miles east), Fleet (5 miles east), Aldershot (8 miles east), Alton (8 miles south) and Yateley (8 miles north-east).

Well-known places in the area include Odiham Castle (0.5 miles north-west) and West Green House Agricultural Museum (3.1 miles north). Not far away are Tundry Hill and The Mill Field.
What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Openings that need collars, wraps, batts or boards rather than sealant
- Issuing fire ratings or certificates for seals
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Cable penetrations
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
General trades versus a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Surface by surface
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do and we will tell you what the detail says instead.
