About our fire rated sealant in Sands End

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. We work on linear gaps, service penetrations and pipe & cable gaps, and the jobs we see most are sealant items on a fire risk assessment action list and ordinary sealant used where a fire-rated product was needed.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Sands End can’t close.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Take photos of fire stopping before ceilings or boxing go back
  • Keep the record of products and locations with your fire safety documents
  • Include hidden areas like risers in routine checks
  • Flag any open gap you spot round a pipe or cable

Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.

Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Why act early in Sands End

If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Sands End, the repair is bigger than a sealant job.

Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

What we do, step by step

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a job in Sands End, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  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 gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints

What the job involves on each surface

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.

Door frames

Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size.

FAQs for Sands End

Do you take on hotel work around Sands End?

Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Can parking be tricky for a visit in Sands End?

Parking in Sands End, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

Do you certify the fire stopping?

We do not give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it.

Can you seal over the old sealant?

No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Can tenants book the work?

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

Is there a guarantee?

Yes. Each job is guaranteed for twelve months, wherever you are.

Do you come to Sands End?

Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes Sands End.

Are you insured?

Yes. We’re fully insured.

Do you need fire rated sealant in Sands End?

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. Rushed fire stopping is common.

Any of these means the joints need attention:

  • Joints picked up in a fire-stopping survey
  • Damaged fire sealant left by other trades
  • Standard silicone or caulk in a fire-stopping gap
  • Gaps where walls meet ceilings or slabs

If you look after a church, hall or community building such as St Mary's Church, older buildings that have had new heating or wiring often have service gaps worth checking.

When it isn’t the sealant

We’ll always be straight with you, so here’s what new sealant won’t do:

  • Issuing a fire rating or certificate for a building
  • Fire risk assessments, which need a qualified assessor
  • Large holes that need a different fire-stopping system

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

DIY sealant or a professional job?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

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.
