Fire rated sealant in Walton-on-Thames, done properly

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. If you have new service routes left unsealed after building work and gaps flagged on a fire risk assessment, we can put it right.

For anyone managing a school, care home, pub or office in Walton-on-Thames, washroom sealant, kitchen joints and fire-rated sealant around service openings all need upkeep. Out-of-hours working is possible to arrange.

All of our work is guaranteed for twelve months.

How it works

There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on how many gaps there are, including the tidy-up. In Walton-on-Thames, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.

  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.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about parking restrictions

Surface by surface

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for each gap size.

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

What affects the cost of fire rated sealant

You’ll get a clear quote before we start. It takes into account:

  • How many rooms, windows or areas are involved
  • The old material and how stubborn it is
  • Mould in or behind the old joints
  • How easy the joints are to reach

What you pay reflects the work, not guesswork. That’s why we ask about the job first.

What we need to know

To make quoting easier, please include:

  • Whether it has been sealed before
  • The problem you’ve noticed
  • The address or postcode of the job
  • Roughly how big the job is

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

Commercial buildings in Walton-on-Thames

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 work to the specification you’re given, installing the product to its tested details.

For site and facilities teams at buildings such as Walton Oak Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like St John are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Work for landlords, hotels and businesses

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

Looking after it afterwards

Aftercare is simple:

  • Photograph sealed gaps before they’re covered up
  • Look in service cupboards and ceiling voids from time to time
  • Do not paint over fire sealant until it has cured
  • Never patch a fire seal with standard sealant

Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

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

Walton-on-Thames: your questions answered

I let a flat near Walton-On-Thames station. Can you help?

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.

Is fire rated sealant in Walton-on-Thames guaranteed?

Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

Do you take out the old sealant first?

Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

Do you have insurance?

Yes, we are fully insured.

Does someone need to be in?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Do you certify the fire stopping?

Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.

What do you put in the joint?

Each joint gets the product that suits it. Movement, water and weather all affect the choice.

Can you quote for more than one area?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

  • Are they insured?
