What affects the cost of fire rated sealant

Every job gets its own quote. This is what makes a difference:

  • When we can work, for business premises
  • How many areas need sealing
  • Whether the work is at height
  • The type of sealant required

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

  • The type of property

Fire rated sealant for homes and businesses in Stonehills

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’re dealing with gaps flagged on a fire risk assessment and new service routes left unsealed after building work, we can put it right, whatever the surface.

In a village or hamlet like Stonehills, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Whatever the size of the job, you get the same 12-month guarantee in Stonehills and across Hampshire.

Aftercare tips

Simple care keeps the joints in good condition. Our advice:

  • Flag any open gap you spot round a pipe or cable
  • Do not paint over fire sealant until it has cured
  • Allow for resealing whenever new services are run
  • Keep the record of products and locations with your fire safety documents

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.

How the job changes by surface

Service penetrations

New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth with backing where the detail needs it.

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Why act early in Stonehills

Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Around Stonehills, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email and we’ll talk you through it.

Why book with us

What fire rated sealant looks like in Stonehills

For seaside hotels, guest houses and holiday lets around Stonehills, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

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

Stonehills: your questions answered

Do you work in hotels near Stonehills?

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

Is Stonehills within the area you cover?

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

Do you provide details of the products used?

Yes. Locations and products are written up when we finish. If you need photos or a set layout, ask when you get a quote.

Do you take out the old sealant first?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Do you certify the fire stopping?

Ratings and certificates are not something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.

Is the work guaranteed?

Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.

Will you assess my building’s fire safety?

No. We work from the specification you give us and install to the manufacturer’s details.

Do you do fire sealant around door frames?

Yes, where the gap suits a sealant detail. Our work is the gap around the frame.
