Questions from Sutton

Is Sutton within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you do fire rated sealant in Sutton?

Yes, Sutton is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.

Is the work guaranteed?

Yes. All our work carries a 12-month guarantee.

Can you do several jobs on one visit?

Yes. Just list everything you need and we’ll quote it together.

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.

What’s the difference between intumescent and fire-rated sealant?

An intumescent sealant expands when it gets hot, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

Is it OK to seal over old sealant?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Are you fully insured?

Yes. We are fully insured, and we have been doing sealant work for more than 20 years.

Do you need fire rated sealant in Sutton?

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.

Look out for these signs:

  • Gaps around pipes and cables through fire-resisting walls
  • Gaps left after a refit or conversion
  • Door frames with gaps between frame and wall
  • Gaps where walls meet ceilings or slabs

Letting a property close to Hanborough station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Choosing a sealant specialist

What we cannot put right

We won’t take on work that will not last, so here’s what sealant can’t put right:

  • Openings too large for sealant, which need batts, boards or another system
  • Walls or floors that weren’t built to resist fire
  • Assessing a building’s fire safety

Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

Joints and surfaces we work on

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

What affects the cost of fire rated sealant

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

  • Working hours on commercial sites
  • Mould in or behind the old joints
  • How many areas need sealing
  • Access and height

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

Helping us quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • The problem you’ve noticed
  • How we’d reach the joints
  • If someone has resealed it before
  • Photos by email, if that’s easy

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Take pictures of fire stopping before ceilings or boxing go back
  • Include hidden areas like risers in routine checks
  • Tell trades working in the building that fire seals must be put back
  • Ask which product was used before you paint

Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is generally a straightforward job.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Commercial buildings in Sutton

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like Church of St Michael are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like Stanton Harcourt CofE Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

What happens on the day

On the day, we start by going over the job with you. We protect the surfaces around the joints before we start. The work usually takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Sutton, the journey is planned in advance: 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. 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. Unsuitable material such as ordinary foam or silicone is cut out.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your files.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Keep pets and children clear of the area while we work
  • Let us know about parking restrictions

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. Older cottages and farmhouses around Sutton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
