Common questions in Walderslade

Is Walderslade in your area for fire rated sealant?

Yes, Walderslade is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.

Do you cover smaller places like Walderslade?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Is it worth trying it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

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

No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.

Do you do fire sealant around door frames?

Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.

What fire rating will the seal have?

Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.

I’m a tenant. Can you help?

We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

Do you offer different sealant colours?

In most cases you can choose. We’ll explain which colours are available and agree one before we start.

How we handle fire rated sealant in Walderslade

We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. Typical jobs include fire stopping disturbed by later work and fire seals that have cracked with movement, on door frames, linear gaps and service penetrations.

In a smaller place like Walderslade, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. The work is the same as in a big building, just on a smaller scale.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Ask which product was used before you paint
  • Flag any open gap you spot round a pipe or cable
  • Take photos of fire stopping before ceilings or boxing go back
  • Never patch a fire seal with standard sealant

Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.

A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so you can show it was dealt with.

Common problems we fix in Walderslade

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

The problems people usually mention when they call are:

  • Fire seals that have cracked with movement
  • Gaps flagged on a fire risk assessment
  • Linear gaps at the head of walls
  • Unsealed gaps where pipes and cables go through a wall

If you let a flat or house near Chatham station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Choosing a sealant specialist

What sealant work cannot fix

It helps to know what we can’t do:

  • Fire doors that need new seals, closers or hardware
  • Deciding what fire stopping a building needs
  • A wall that isn’t a fire-resisting element to begin with

If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Surfaces we seal

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

What happens if it’s left?

Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Around Walderslade, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Can I do it myself?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

How the visit works

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of gaps, and longer for a whole building. For a job in Walderslade, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Finally, we list where we worked and what we used, for your records.

Preparing for the visit

  • For business premises, tell us about site rules or sign-in
  • Mention any leaks or damp you’ve noticed
  • Let us know about parking restrictions

What fire rated sealant looks like in Walderslade

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

If you look after a building such as Tunbury Primary School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like St William's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
