Fire rated sealant for East Street homes and businesses

Fire rated sealant for homes and businesses in East Street

Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. We work on linear gaps, flats & HMOs and service penetrations, and common reasons people get in touch are gaps where walls meet ceilings or slabs and open gaps behind door architraves.

For a small place like East Street, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

Every job comes with our one-year guarantee.

What we can’t put right

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Openings too large for sealant, which need batts, boards or another system
  • Issuing a fire rating or certificate for a building
  • Deciding what fire stopping a building needs

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

What we seal

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

How it works

Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like East Street needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

Before we arrive

  • Keep children and pets away from the work area
  • Mention if the joints have been sealed before
  • On commercial sites, let us know about site rules

East Street: your questions answered

Do you cover smaller places like East Street?

Yes. East Street is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Will you leave a mess?

We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.

How long does fire rated sealant take?

That depends on the amount of work, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We’ll tell you when we quote.

Where do you work from?

We work from Crawley. We cover East Street and the rest of Kent.

Can you quote for more than one area?

Yes. Just list everything you need and you’ll get one quote.

Do you guarantee your work?

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

Surface by surface

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each, and tell you if sealant alone is not the right fix.

Door frames

Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist, and we’ll say if we spot a problem with them.

Common problems we fix in East Street

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.

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

  • Gaps filled with a product that isn’t fire-rated
  • Linear gaps at the head of walls
  • Gaps left after a refit or conversion
  • Sealant items on a fire risk assessment action list

Community buildings like Church of St Nicholas are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Choosing a sealant specialist

Why act early in East Street

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like East Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Why us?

  • Quality sealants from Arbo and Everbuild
  • An ARBOMaster approved applicator
  • We’re fully insured
  • A 12-month guarantee on all work

Fire rated sealant in East Street: local notes

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.

For landlords with property near Sandwich station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Sandwich Technology School, service openings in fire-resisting walls need checking after any refurbishment.

Should I try it myself first?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
