Fire rated sealant in Sandway

Work for landlords, hotels and businesses

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.

Landlords and letting agents in Sandway can book us as well as householders. Resealing between tenancies keeps a property looking cared for.

How we handle fire rated sealant in Sandway

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. If you have gaps left after a refit or conversion and sealant items on a fire risk assessment action list, we can help.

If you have holiday lets, a converted barn used for business or a community building near Sandway, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

Every job is covered by a 12-month guarantee, wherever you are in Kent.

Sandway: your questions answered

Can you help a landlord with a rental near Lenham station?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Do you work for hotels and guest houses in Sandway?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Is standard sealant good enough for a fire gap?

No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service.

Do you guarantee your work?

Yes. Every job comes with our 12-month guarantee.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Can you match the sealant colour?

Normally, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.

Do you certify the fire stopping?

Ratings and certificates aren’t something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.

Is it OK to seal over old sealant?

No, because it fails. We remove every bit of old sealant first.

What sealant work cannot fix

Before booking, it’s worth knowing the limits too:

  • Walls or floors that weren’t built to resist fire
  • Assessing a building’s fire safety
  • Big openings where sealant alone is not the tested solution

If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.

Joints and surfaces we work on

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

What affects the cost of fire rated sealant

Every job gets its own quote. These are the things that affect it:

  • How much there is to do
  • The product the joint needs
  • How many areas need sealing
  • Any mould that needs treating

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What to tell us for a quote

When you contact us, it’s useful to know:

  • Any previous sealing or DIY work
  • A few photos by email, if you can
  • Access, such as stairs, a lift or height
  • Roughly how big the job is

If you are in Sandway and need fire rated sealant, ring 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and you will get a clear quote before we start.

Looking after it afterwards

Looking after new joints is easy, and it makes a real difference:

  • Never patch a fire seal with standard sealant
  • Include hidden areas like risers in routine checks
  • Plan fire stopping into any work that goes through walls or floors
  • Get damaged fire seals looked at promptly

Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Why act early in Sandway

Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Around Sandway, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Workplaces and buildings in Sandway

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, 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. Sandway has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

If you look after a church, hall or community building such as St Mary's Church, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Lenham station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Platts Heath Primary School, service openings in fire-resisting walls need checking after any refurbishment.

How it works

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Sandway needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Move anything stored near the joints
  • Mention if the joints have been sealed before
  • On commercial sites, let us know about site rules
