Need fire rated sealant in Addington?

Addington: your questions answered

I let a flat near West Malling station. Can you help?

Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.

Is Addington within the area you cover?

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

How much does fire rated sealant cost in Addington?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.

Do you guarantee your work?

Yes, always. There’s a 12-month guarantee on every job, wherever you are.

Can I use normal mastic around a pipe through a fire wall?

No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.

How long does the job take?

Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we will say how long yours will take.

Can you fill the gap behind a fire door frame?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product. The door, its seals and closer are for a door specialist.

Fire rated sealant for homes and businesses in Addington

We often work from an action list drawn up by a fire risk assessor for buildings in Addington. If you share the list, we can quote for the gaps that need fire-rated sealant. If you’re dealing with damaged fire sealant left by other trades and standard silicone or caulk in a fire-stopping gap, we can put it right, whatever the surface.

In a village or hamlet like Addington, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

Each job carries a 12-month guarantee, whatever its size.

Commercial buildings in Addington

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Addington has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.

For site and facilities teams at buildings such as Offham Primary School, service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Church of St Margaret, older buildings that have had new heating or wiring often have service gaps worth checking.

Do you need fire rated sealant in Addington?

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common particularly when it was the last job before handover.

If you can see any of these, it’s time to have the joints looked at:

  • Linear gaps at the head of walls
  • Unsealed gaps where pipes and cables go through a wall
  • Gaps flagged on a fire risk assessment
  • Gaps left after a refit or conversion

Rented homes near West Malling station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

How to look after the new joints

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

  • Allow for resealing whenever new services are run
  • Report cracked or damaged seals as soon as you notice them
  • Tell trades working in the building that fire seals must be put back
  • Include hidden areas like risers in routine checks

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

How we quote for fire rated sealant

We quote each job individually. These are the things that affect it:

  • The number and length of the joints
  • Whether the work is at height
  • How many areas need sealing
  • Working hours on commercial sites

We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.

What we need to know

There’s no need for technical detail. It helps if you can tell us:

  • The type of property
  • Photos by email, if that’s easy
  • Access, such as stairs, a lift or height
  • Where the property is

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or send us an email.

Landlords, agents and businesses in Addington

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured for the work.

The process

All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Addington, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

Before we arrive

  • Tell us if parking is tricky
  • Mention if the joints have been sealed before
  • Plan for the work area to be out of bounds to pets and children

Advice

Why deal with it now?

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like Addington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Why us?

  • Any old sealant cut out fully, not covered over
  • Full insurance on every job
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Tidy, careful work

Take a look at what affects the cost or what customers say.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
