Fire stopping for businesses in Cuddesdon

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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.

Fire stopping in Cuddesdon, done properly

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. We work on service gaps in risers, cable penetrations and joints between fire-resisting walls and floors, and what we’re called in for most is openings left by services added after handover and hidden openings found during inspections. One point of contact handles commercial sealant work in Cuddesdon from the first photos to the final walk-round, for single jobs and planned programmes alike.

Rural conversions around Cuddesdon can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Where services cross fire walls in Cuddesdon

Cuddesdon has several hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. At about 47 miles from central London, Cuddesdon is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

On a hospital site such as Slade Hospital, 3.2 miles to the north-west of Cuddesdon, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Shop fits in centres such as Oxford Retail Park (to the west of Cuddesdon) can bring new services through fire-resisting walls between units, which then need the specified seal.

Cuddesdon is about 5 miles south-east of Oxford, in Oxfordshire. Across the OX44 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Oxfordshire coverage takes in 423 places, from busy centres to rural villages.

Anyone looking for fire stopping in OX44 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. We cover commercial and managed buildings on High Street, Church Close and Field Lane. Nearby places we also cover include Denton (1 mile south-west), Blenheim (1 mile west), Garsington (2 miles west), Wheatley (2 miles north) and Littleworth (2 miles north-west). Further afield, our area takes in Oxford (5 miles north-west), Didcot (9 miles south-west), Bicester (12 miles north), Abingdon-on-Thames (7 miles south-west), Thame (7 miles east) and Wantage (15 miles south-west).

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

What we are called out for in Cuddesdon

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.

Clients typically get in touch after noticing something like this:

  • Openings found when ceilings come down for a refit
  • Head-of-wall gaps with no fire seal
  • Old intumescent sealant that has split away
  • Non-fire-rated filler around services

At a university such as Oxford Brookes University, which lies north-west of Cuddesdon, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Questions to ask before you book

  • What site paperwork they can supply
  • Proof of insurance
  • Can the work be phased to keep areas open?
  • Are they CHAS accredited or on Constructionline?

How to choose a sealant contractor

Cuddesdon: questions and answers

Is a hospital such as Slade Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you work on fire-rated sealing in hotels in Cuddesdon?

Yes. We install fire-rated and intumescent sealant where it is specified. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Do you work in Cuddesdon?

Yes. We cover Cuddesdon, within our coverage of Greater London, South East England and Scotland. To discuss a job, ring 01277 525 020 or send details through our quote form.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months on every job.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

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 if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building around Cuddesdon, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Let building users know which areas are affected
  • Agree which areas must stay open
  • Send your site hours and access windows

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Construction that lacks the fire resistance the seal relies on
  • Approving the work on behalf of building control
  • Fire risk assessments, a job for a competent assessor

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly.

Joints and surfaces we work on

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

Cost factors for service penetrations

We price every job individually. The main factors are:

  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements
  • How much existing material needs removing
  • Location, for remote and island sites

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

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • The type of building and who uses it
  • Where the site is, with the postcode
  • Specification clauses that apply
  • When you need the work done

For a fixed quote, phone 01277 525 020 or email us with the site address and an outline of the work. You can also send details through our quote form.
