Need fire stopping in Ockham?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Questions we are asked in Ockham

Does your area include sites such as Wey Retail Park, near Ockham?

Yes. Estates, retail parks and business parks around Ockham, Wey Retail Park among them, are all within reach. A few photographs and the unit address let us price the work.

Is Ockham off your patch?

Not at all. Ockham is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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. Removing asbestos is a job for asbestos specialists, not us.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Fire stopping in Ockham, done properly

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work 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. If you have old intumescent sealant that has split away and open linear gaps along the top of fire-resisting walls, we can help. A specialist sealant contractor works differently from a general builder: on jobs in Ockham, preparation and product choice get the time they need.

Around smaller places like Ockham, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Why deal with it now?

The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Older rural buildings around Ockham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Building owners, agents and FMs in Ockham

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Ockham. Several sites can go on one quote, so there’s one set of paperwork to deal with.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

How a job runs

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Jobs in and around smaller places like Ockham are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot
  • For older buildings, check the asbestos register before work

Getting a fixed quote

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’ll fill any gaps with a visit.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Gaps in walls that were never built as compartment walls
  • Fire risk assessments, a job for a competent assessor
  • Writing the fire-stopping specification

If you are not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Joints and surfaces we work on

  • Service gaps in risers
  • Cable penetrations
  • Linear gaps at wall heads
  • Joints between fire-resisting walls and floors
  • Small duct penetrations where the tested detail allows
  • Pipe penetrations

Service penetrations in Ockham buildings

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. What we install is set by the specification, and it goes in to the tested detail. Central London is about 21 miles from Ockham. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

Older community buildings such as All Saints' Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Hotels such as The Hautboy Hotel (to the north of Ockham) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Ockham is about 5 miles east of Woking, in Surrey. Any commercial site in Ockham is covered, for single jobs and planned programmes alike. Ockham is one of 379 places in Surrey on our list. Our London page has more on work in that area (21 miles or so).

Anyone looking for fire stopping in GU23 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Buildings on Alms Heath, Ockham Lane and School Lane are within our area for service penetrations. Just outside Ockham, we also work in West Horsley (2 miles south), Ripley (2 miles west), East Horsley (2 miles south-east), Effingham (3 miles south-east) and East Clandon (3 miles south). A short drive away, we cover Guildford (6 miles south-west), Woking (5 miles west), Camberley (12 miles west), Epsom (9 miles east), Horley (15 miles south-east) and Redhill (13 miles east).

Doing it in-house

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

When to call us in Ockham

Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.

Site and facilities staff are often the first to spot these:

  • Openings left by services added after handover
  • Hidden openings found during inspections
  • Builders’ foam or ordinary silicone in compartment walls
  • Improvised or mixed-product fire seals

Holiday works at schools like Ripley Court School often leave service openings to seal before pupils return.

Before you book anyone

  • Their approach to joint depth and backing
  • Their public liability cover
  • The named product and why it was chosen
  • How long is the guarantee, and what does it include?
