Fire rated sealant in Upper Heyford

Fire rated sealant around Upper Heyford

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Rented homes near Heyford station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Fire rated sealant in Upper Heyford

We can work through a building room by room or floor by floor. That record is useful for your files and for whoever looks at the building next. If you have unsealed gaps where pipes and cables go through a wall and old fire sealant that has split or come away, we can put it right, on service penetrations, plasterboard & masonry and linear gaps alike.

Commercial work around a smaller place like Upper Heyford generally means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.

Every job is covered by our one-year guarantee.

Aftercare tips

Joint life depends on how it’s used and looked after. We suggest:

  • Tell trades working in the building that fire seals must be put back
  • Plan fire stopping into any work that goes through walls or floors
  • Flag any open gap you spot round a pipe or cable
  • Never patch a fire seal with standard sealant

Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.

Common problems we fix in Upper Heyford

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

Keep an eye out for these signs:

  • Gaps left after a refit or conversion
  • Open holes round services passing through fire walls
  • Gaps flagged on a fire risk assessment
  • Door frames with gaps between frame and wall

For buildings such as Heyford Park Chapel, older buildings that have had new heating or wiring often have service gaps worth checking.

What your quote should include

  • Are they insured?
  • How the joint is cleaned and prepared
  • How much experience the applicator has
  • How hidden problems are handled

What sealant work cannot fix

It helps to know what we cannot do too:

  • Construction that doesn’t provide fire resistance on its own
  • Openings too large for sealant, which need batts, boards or another system
  • Problems with the door itself rather than the gap around the frame

Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.

Landlords, agents and businesses in Upper Heyford

Landlords and agents in Upper Heyford can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Upper Heyford: your questions answered

Will you come out to Upper Heyford?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you do fire rated sealant in Upper Heyford?

Yes, Upper Heyford is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.

Do you offer different sealant colours?

Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.

Will we have a record of what was sealed?

Yes. We record the locations we have sealed and the products used for your files.

What fire rating will the seal have?

We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.

How long does the job take?

Typically it takes from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer.

Are you an approved applicator?

Yes. We’re an ARBOMaster approved applicator.

What’s the difference between intumescent and fire-rated sealant?

Intumescent means it swells when heated, helping close the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.

How it works

There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on how many gaps there are in most cases. Parking around Upper Heyford is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products.

How to prepare

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention if the joints have been sealed before
  • Move anything stored near the joints

Advice

Surface by surface

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified, flat by flat if needed.

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach and we’ll flag it.

What affects the quote in Upper Heyford

For a quick quote, just ask. What matters most is:

  • How many rooms, windows or areas are involved
  • How much old sealant there is and how hard it is to remove
  • Mould in or behind the old joints
  • Whether the work is at height

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What we need to know

Photos help, but a description is a good start. Try to tell us:

  • If someone has resealed it before
  • Access, such as stairs, a lift or height
  • Where the property is
  • Photos by email, if that’s easy

Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job.
