Whitehill questions

Do you cover Whitehill for fire rated sealant?

Yes, Whitehill is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.

Do you cover smaller places like Whitehill?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

What does fire rated sealant cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.

Is standard sealant good enough for a fire gap?

No. It might close the gap, but it isn’t a fire-rated seal. A tested fire-rated product is needed and we can apply it for you.

Can I choose the sealant colour?

Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.

Can I do it myself?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Can you tell me which gaps need fire stopping?

No. We follow the requirements from your assessor, designer or building control.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Fire rated sealant in Whitehill, done properly

Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. Common call-outs are for seals cut through by electricians, plumbers or data installers and sealant items on a fire risk assessment action list, on pipe & cable gaps, service penetrations and plasterboard & masonry.

For a pub, café, guest house or shop in or near Whitehill, its washrooms and kitchen need the same sealant care as any big building.

We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Fire rated sealant in Whitehill: local notes

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

For buildings such as St Mark's Sacred Church, gaps around pipes and cables are worth checking after any building work there. If you let a flat or house near Liphook station, any gap left by new services in shared walls should be closed with a fire-rated product.

Whitehill is about 6 miles south-east of Alton, in Hampshire. Whitehill gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Our area takes in 683 places across Hampshire. Portsmouth is on our list too, about 22 miles from Whitehill.

Here we cover the GU35 postcode area for fire rated sealant. Streets in the area include Stubbington Avenue, Petersfield Road and Dudley Close. Other places close to Whitehill include Hollywater (1 mile east), Bordon (1 mile north), Deadwater (1 mile north-east), Pinewood Village (1 mile north) and Standford (1 mile east). We also work in nearby towns such as Basingstoke (15 miles north-west), Farnborough (14 miles north), Fleet (12 miles north), Horndean (15 miles south-west), Aldershot (11 miles north-east) and Alton (6 miles north-west).

Landmarks near Whitehill

Signs you need fire rated sealant in Whitehill

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Keep an eye out for any of the following:

  • Holes left by a change of layout
  • Gaps flagged on a fire risk assessment
  • Unsealed gaps where pipes and cables go through a wall
  • Ordinary sealant used where a fire-rated product was needed

Managing a site like Woodlea Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Our hiring checklist

What we can’t put right

We will always be straight with you, so here’s what new sealant won’t do:

  • Big openings where sealant alone is not the tested solution
  • Sign-off of the building, which sits with building control or your assessor
  • Fire doors that need new seals, closers or hardware

Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.

What we seal

  • Pipe & cable gaps
  • Door frames
  • Service penetrations
  • Plasterboard & masonry
  • Linear gaps
  • Flats & HMOs

How it works

Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on how many gaps there are. For a job in Whitehill, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your files.

Preparing for the visit

  • For business premises, tell us about site rules or sign-in
  • For indoor joints, keep the area dry beforehand if you can
  • Clear the area around the work

Landlord and commercial work in Whitehill

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured for the work.

Why it’s worth doing now in Whitehill

An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. In a smaller place like Whitehill, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.

What you get with us

  • Full insurance on every job
  • Neat joints and a tidy finish
  • A 12-month guarantee on all work

Surface by surface

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
