Fire stopping near Iffley

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

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Fire risk assessments, a job for a competent assessor
  • Deciding what a wall or floor needs, which belongs to the designer
  • Large openings beyond what any sealant detail covers

If you are not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer.

Where we work in Iffley

  • Cable 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
  • Pipe penetrations

How we handle fire stopping in Iffley

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. We close the openings listed on your schedule, using the specified sealant and detail. If you have unsealed penetrations discovered above suspended ceilings and open linear gaps along the top of fire-resisting walls, we can put it right, whatever the surface. A single leaking joint is often how a building in Iffley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around Iffley, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photographs of the openings and we’ll quote to suit.

A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or email us and we will arrange a return visit.

Questions about Iffley

Is Iffley too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Would you work within a site like Warneford Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Will fire-rated sealant work on every penetration?

No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.

Do you certify or sign off fire stopping?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Penetration seals near Iffley

The 2 miles around Iffley include six care or nursing homes. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

Workshops and IT rooms at colleges like Oxford Sixth Form College, 1.9 miles to the north-west of Iffley, are re-serviced often, leaving penetrations to seal. For a hotel such as Mercure Oxford Hawkwell House Hotel, less than half a mile to the west of Iffley, penetration seals are worth checking after any refit or services upgrade. Shop fits on retail sites such as Templars Shopping Park (to the north-east of Iffley) can bring new services through fire-resisting walls between units, to be sealed with the specified product.

Building owners, agents and FMs in Iffley

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

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For a site in Iffley, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Share the asbestos register for older buildings
  • Tell us which areas need to stay in use
  • Have the specification and drawings to hand

Quoting for work in Iffley

Your fixed quote is built from the real scope. It takes account of:

  • Which sealant the job calls for
  • Distance, for remote addresses
  • Quantities, in metres or numbers
  • Working within restricted access windows

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What to include in your enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • A wide shot and a close-up of the area
  • Any dates the work must fit around
  • Access details, including height
  • The asbestos register, for older buildings

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send details through our quote form.

How the job changes by surface

Drylining partitions

Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers.

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we will never swap a specified collar for sealant.

Why deal with it now?

Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these, and the other benefits follow. Small buildings around Iffley suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Why appoint us

  • Work carried out by CSCS-carded applicators
  • Old sealant cut out, never sealed over
  • Health and safety: CHAS accredited
  • 12-month guarantee on workmanship
