About our fire rated sealant in Walstead

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 are dealing with gaps flagged on a fire risk assessment and ordinary sealant used where a fire-rated product was needed, we can help.

For holiday lets, converted business premises or a community building near Walstead, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What fire rated sealant looks like in Walstead

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 work to the specification you are given, installing the product to its tested details.

For landlords with property near Haywards Heath station, any gap left by new services in shared walls should be closed with a fire-rated product. Schools such as Northlands Wood Primary Academy are buildings too, and fire-stopping around service openings should be restored whenever new services go in. For buildings such as Church of the Good Shepherd, service openings in its walls need the right fire-rated sealant, as in any building.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

Aftercare tips

So the new joints stay in good condition:

  • Photograph sealed gaps before they’re covered up
  • Never patch a fire seal with standard sealant
  • Ask which product was used before you paint
  • Include fire stopping when you schedule refits

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

Why it’s worth doing now in Walstead

Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We will say so if a gap needs something other than sealant. Around Walstead, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

  • More than 20 years in sealant work
  • Experience in homes, commercial sites and hotels

FAQs for Walstead

I let a flat near Haywards Heath station. Can you help?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.

Do you cover smaller places like Walstead?

Yes, Walstead is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

What does fire rated sealant cost?

Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or email us and let us know what needs doing and where.

Does someone need to be in?

That depends on where the joints are. Inside work needs someone to give us access.

Can ordinary silicone be used in a fire-stopping gap?

No. It might close the gap, but it isn’t a fire-rated seal. A tested fire-rated product is needed.

Can you match the sealant colour?

We help you choose a colour that suits. The choice depends on the product the joint needs.

Can you quote for more than one area?

Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

Are you fully insured?

Yes. We are fully insured, and we can confirm the details when we quote.

When it is not the sealant

We will not take on work that will not last, so these are the limits:

  • Sign-off of the building, which sits with building control or your assessor
  • Openings too large for sealant, which need batts, boards or another system
  • Problems with the door itself rather than the gap around the frame

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

Where we work in Walstead

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

Surface by surface

Service penetrations

New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run leaving no stretch unsealed.

What affects the cost of fire rated sealant

You’ll get a clear quote before any work starts. It’s based on:

  • The number of rooms or windows
  • The product the joint needs
  • How easy the joints are to reach
  • Any working-time requirements on site

To help us quote quickly, let us know:

  • A few pictures by email, if you can
  • What’s wrong with the joints now
  • Any access issues, like height or stairs
  • Where the job is, and your postcode

We quote each job on its own. Simply call 0345 464 0079 or drop us an email and describe the job and send pictures if you have them.

How it works

The work is kept neat and contained to the joints we’re treating. The job usually takes from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. Somewhere as small as Walstead, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • For business premises, tell us about site rules or sign-in
  • Tell us about access, such as stairs, a lift or high-level joints
