Fire stopping across Abingdon-on-Thames

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Surface by surface

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes. We confirm material and size first and tell you if sealant isn’t the right product.

Linear joints

Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, with no gaps along the run.

How we handle fire stopping in Abingdon-on-Thames

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Abingdon-on-Thames. The enquiries we see most involve open linear gaps along the top of fire-resisting walls and fire-stopping items raised at inspection or handover, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and pipe penetrations. A single leaking joint is often how a building in Abingdon-on-Thames first comes to us: we look at the rest while we’re there and tell you what we find.

Many town-centre buildings in places like Abingdon-on-Thames have had layer upon layer of new services, and each change can leave unsealed holes in walls and floors. Our applicators follow the product’s published detail for that wall or floor whenever fire-rated sealant is the chosen seal.

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.

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. If you have more than one building in Abingdon-on-Thames, they can often be done on the same visit, with one quote covering them. Tell us when the building is open and we will plan to suit.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  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.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements

Leave it or put it right?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. Many buildings in towns like Abingdon-on-Thames have been extended or altered, so joints between old and new are often the first to go. Resealing them early protects the building behind.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Take a look at what affects the cost and our accreditations.

After the work

Once the work is signed off, these steps help:

  • Agree the fire-stopping specification before services go in
  • Leave fire sealant to cure fully before covering it
  • Put resealing into every M&E and fit-out package
  • Keep general-purpose fillers away from compartment walls

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, and the data sheet says which.

Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.

Fire-rated sealing for Abingdon-on-Thames buildings

The area within 2 miles of Abingdon-on-Thames holds a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. At about 52 miles from central London, Abingdon-on-Thames is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.

At a college such as Abingdon & Witney College: Abingdon Campus (under half a mile north-west of Abingdon-on-Thames), checking penetration seals after summer M&E works is good practice. For a unit at a site such as Radley Road Industrial Estate (0.7 miles east of Abingdon-on-Thames), new power or data runs between office and warehouse can breach a compartment wall. Shop fits in centres such as Fairacres Retail Park, 1.1 miles south-west of Abingdon-on-Thames, can bring new services through fire-resisting walls between units, which then need the specified seal.

Questions we’re asked in Abingdon-on-Thames

Do you cover business parks and estates near Abingdon-on-Thames, such as Radley Road Industrial Estate?

Yes. Our area takes in Abingdon-on-Thames and its surroundings, with estates and business parks such as Radley Road Industrial Estate included. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.

How does the move away from BS 476 affect penetration seals in Abingdon-on-Thames?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How much does the work cost?

We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
