Fire stopping for businesses in Fritwell

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

Fire stopping in Fritwell

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. 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. Site teams most often ask us about snag lists that include open service penetrations and openings found when ceilings come down for a refit, on cable penetrations, pipe penetrations and small duct penetrations where the tested detail allows. Facilities teams, main contractors and managing agents in Fritwell tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A job near Fritwell is normally 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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Service penetrations in Fritwell buildings

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Fritwell lies roughly 58 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

In a school such as Fritwell Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified. For a hospital such as Bicester Community Hospital, 5.4 miles south-east of Fritwell, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. On estates like Baynards Green Trading Estate, which lies east of Fritwell, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Fritwell is about 5 miles north-west of Bicester, in Oxfordshire.

Why act early in Fritwell

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. One visit to deal with every failing joint makes more sense than several trips to a place like Fritwell. Send photographs of each area and we’ll quote for the lot.

We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Why appoint us

  • One contact handling all your sites
  • Health and safety: CHAS accredited
  • Work to your specification and the manufacturer’s guidance
  • Sealing commercial buildings since 2005

Doing it in-house

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.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Diagnose, treat, sign off

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs in and around smaller places like Fritwell are typically planned as a single visit, so photos 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 so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Point out any areas we must not close
  • Send any specification or drawings in advance
  • Tell staff and tenants when we will be in

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Questions we’re asked in Fritwell

Is a hospital such as Bicester Community Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Is Baynards Green Trading Estate, near Fritwell, within your area?

Yes. Estates, retail parks and business parks around Fritwell, Baynards Green Trading Estate among them, are all within reach. A few photos and the unit address let us price the work.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Is fire stopping in Scotland covered by different guidance?

Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.

Do you cover Fritwell?

Yes. Fritwell is in our area and the rest of Oxfordshire, within our coverage of Greater London, South East England and Scotland. To discuss a job, give us a call on 01277 525 020 or email the details over.

Is colour matching possible?

It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Large openings beyond what any sealant detail covers
  • Construction that lacks the fire resistance the seal relies on

If you are not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer.

Where we work in Fritwell

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

Owners, agents and contractors

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • How much there is to seal
  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • Any access equipment needed

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
  • The postcode of the building

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
