Fire rated sealant near Whitwell

The process

Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Whitwell, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your files.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • Try not to wet indoor joints just before the visit
  • Keep pets and children clear of the area while we work

Fire rated sealant for homes and businesses in Whitwell

Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. We work on flats & HMOs, pipe & cable gaps and linear gaps, and people most often call us about door frames with gaps between frame and wall and standard silicone or caulk in a fire-stopping gap.

For holiday lets, converted business premises or a community building near Whitwell, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

You get a one-year guarantee, the same in Whitwell as everywhere else we work.

DIY sealant or a professional job?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

How to look after the new joints

Aftercare is simple:

  • Make resealing part of every contractor’s brief
  • Plan fire stopping into any work that goes through walls or floors
  • Check whether a sealant can be painted before decorating over it
  • Never patch a fire seal with standard sealant

Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the list grows.

Whitwell: your questions answered

I let a flat near Shanklin station. Can you help?

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

Is Whitwell within the area you cover?

Yes, Whitwell is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do I need to be at home?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Can you fill the gap behind a fire door frame?

Yes, where the gap suits a sealant detail. Our work is the gap around the frame and we will tell you if we spot problems with the door.

Where do you work from?

We work from Crawley. Our applicators cover Whitwell, along with the rest of our area.

Can you tell me how many minutes the seal will last?

We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.

Do you guarantee your work?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Do you remove the old sealant?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Commercial buildings in Whitwell

If you run a hotel, guest house or holiday let in a coastal place like Whitwell, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Schools such as Niton Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. If you let a flat or house near Shanklin station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of St. Mary and St. Radegund, service openings in its walls need the right fire-rated sealant, as in any building.

What the job involves on each surface

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Door frames

Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details before the trim goes back.

Landlords, agents and businesses in Whitwell

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

For anyone letting property in or around Whitwell, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.

When something else is needed

  • Issuing a fire rating or certificate for a building
  • A wall that is not a fire-resisting element to begin with
  • Assessing a building’s fire safety

If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

  • Linear gaps
  • Door frames
  • Plasterboard & masonry

Why it’s worth doing now in Whitwell

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. Older cottages and farmhouses around Whitwell can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.
