Fire rated sealant for homes and businesses in Surbiton Park

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. We work on door frames, service penetrations and pipe & cable gaps, and people most often call us about holes left by a change of layout and ordinary sealant used where a fire-rated product was needed.

In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Surbiton Park, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

There’s a 12-month guarantee on every job, large or small.

What happens on the day

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Surbiton Park. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Tell us if parking is tricky
  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any sign-in or site rules at work premises

How to look after the new joints

After the cure time, these simple habits help:

  • Keep the record of products and locations with your fire safety documents
  • Make resealing part of every contractor’s brief
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Look in service cupboards and ceiling voids from time to time

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.

How the job changes by surface

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.

What sealant work can’t fix

A few problems are outside what sealant work can do:

  • Doors that aren’t fire doors in the first place
  • A wall that is not a fire-resisting element to begin with
  • Sign-off of the building, which sits with building control or your assessor

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

Where we work in Surbiton Park

  • Service penetrations

Quotes for fire rated sealant in Surbiton Park

We don’t publish a price list, because no two jobs are the same. What we look at:

  • The product the joint needs
  • Mould in or behind the old joints
  • How many rooms, windows or areas are involved
  • How easy the joints are to reach

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What to tell us for a quote

There’s no need for technical detail. Just tell us:

  • Roughly how big the job is
  • The problem you’ve noticed
  • The address or postcode of the job
  • If someone has resealed it before

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or drop us an email.

Why it’s worth doing now in Surbiton Park

Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In a flat in Surbiton Park, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

  • Trusted Arbo and Everbuild sealants
  • Rated 4.9 stars on Google
  • 20+ years of sealant experience
  • Every job guaranteed for a year

Signs you need fire rated sealant in Surbiton Park

Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

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

  • Open gaps behind door architraves
  • Gaps filled with a product that isn’t fire-rated
  • Cracked or shrunken fire-rated sealant
  • Sealant items on a fire risk assessment action list

For landlords with property near Surbiton station, any gap left by new services in shared walls should be closed with a fire-rated product.

  • Which sealant they’ll use, and why
  • How the colour is chosen
  • Is the old sealant removed completely?
  • When the joint can take water or movement

What fire rated sealant looks like in Surbiton Park

Surbiton Park has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
