Trusted fire rated sealant in Christmas Common

Fire rated sealant for homes and businesses in Christmas Common

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. We work on plasterboard & masonry, pipe & cable gaps and linear gaps, and the jobs we see most are gaps left after a refit or conversion and sealant items on a fire risk assessment action list.

For holiday lets, converted business premises or a community building near Christmas Common, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

We stand behind the work with a 12-month guarantee.

Your questions about fire rated sealant in Christmas Common

Is fire rated sealant in Christmas Common guaranteed?

Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

Do you cover Christmas Common for fire rated sealant?

Yes. We work across London and the South East, and Christmas Common is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.

Can ordinary silicone be used in a fire-stopping gap?

No. Ordinary silicone, caulk or foam is not tested as fire stopping. We cut it out and reseal with a fire-rated product.

Do you have insurance?

Yes. We are fully insured for domestic and commercial work.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status.

Can you do several jobs on one visit?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

What fire rating will the seal have?

We don’t 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.

What does fire rated sealant cost?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Work for landlords, hotels and businesses

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

What the job involves on each surface

Linear gaps

Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement.

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in.

Commercial buildings in Christmas Common

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.

Managing a site like Icknield Community College? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Aftercare tips

After the cure time, these simple habits help:

  • Ask which product was used before you paint
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Allow for resealing whenever new services are run
  • Photograph sealed gaps before they’re covered up

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.

Should I try it myself first?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

When something else is needed

A few problems are outside what sealant work can do:

  • A wall that isn’t a fire-resisting element to begin with
  • Problems with the door itself rather than the gap around the frame
  • Deciding what fire stopping a building needs

If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

What we seal

  • Plasterboard & masonry
  • Service penetrations
  • Linear gaps
  • Door frames
  • Flats & HMOs
  • Pipe & cable gaps

How it works

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on how many gaps there are. In a small place like Christmas Common, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used for your records.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Mention if the joints have been sealed before
  • Keep pets and children clear of the area while we work

Advice

What we are called out for in Christmas Common

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.

Most people get in touch when they notice one of these:

  • Old fire sealant that has split or come away
  • Fire stopping disturbed by later work
  • Door frames with gaps between frame and wall
  • Unsealed gaps where pipes and cables go through a wall

Community buildings like Church of the Nativity are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

What to look for in a quote

  • What happens if they find a problem under the old sealant
  • Is VAT in the price?
  • What guarantee comes with the work
  • How the joint is cleaned and prepared
