Why act early in Westmarsh

Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again when the building is next checked. In a small place like Westmarsh, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Why book with us

  • We never seal over old sealant

Fire rated sealant in Westmarsh

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. We work on service penetrations, plasterboard & masonry and pipe & cable gaps, and people most often call us about gaps flagged on a fire risk assessment and fire seals that have cracked with movement.

If you have holiday lets, a converted barn used for business or a community building near Westmarsh, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Every job comes with our 12-month guarantee.

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Fire rated sealant in Westmarsh: 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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Rented homes near Minster station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Around Westmarsh, as everywhere, fire rated sealant is only as good as the preparation behind it.

Westmarsh is about 7 miles west of Ramsgate, in Kent. Wherever you are in the CT3 postcode area, our applicators can take on fire rated sealant. Our area takes in 922 places across Kent, from the larger towns to small villages. Our Chelmsford page covers work nearby (45 miles or so).

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

  • Allow for resealing whenever new services are run
  • Keep photos of seals that will be hidden
  • Tell trades working in the building that fire seals must be put back
  • 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 get them seen to.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

How the visit works

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on how many gaps there are in most cases. Somewhere like Westmarsh needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  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 for your records.

Getting ready for the visit

  • Tell us about any water getting in
  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep pets and children clear of the area while we work

What sealant work can’t fix

In fairness, there are a few things sealant won’t fix:

  • A wall that isn’t a fire-resisting element to begin with
  • Fire risk assessments, which need a qualified assessor
  • Large holes that need a different fire-stopping system

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

Surfaces we seal

  • Door frames
  • Linear gaps
  • Plasterboard & masonry
  • Pipe & cable gaps

Westmarsh: your questions answered

Do you cover Westmarsh for fire rated sealant?

Yes. Our work covers London and the South East, and Westmarsh is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.

Will you come out to Westmarsh?

Yes, we do. 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.

Is it OK to seal over old sealant?

No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Should I try DIY first?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

What do you put in the joint?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Is there a guarantee?

Yes. There’s a 12-month guarantee on every job, wherever you are.

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Can I use normal mastic around a pipe through a fire wall?

No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service, or ask us to do it.

Work for landlords, hotels and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for.

What affects the quote in Westmarsh

Every job gets its own quote. These are the things that affect it:

  • Any working-time requirements on site
  • The amount of work
  • How much old sealant there is and how hard it is to remove
  • Any mould that needs treating

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

Helping us quote

When you call or email, it’s useful to know:

  • What the problem is, such as mould, gaps, leaks or cracking
  • The type of property
  • Photos by email, if that is easy
  • How we’d reach the joints

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
