Leave it or put it right?

Squirting in whichever sealant is nearest doesn’t make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In an older home around Sompting, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

About our fire rated sealant in Sompting

Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Common call-outs are for sealant items on a fire risk assessment action list and open gaps behind door architraves, across pipe & cable gaps, door frames and service penetrations.

For a pub, café, guest house or shop in or near Sompting, its washrooms and kitchen need the same sealant care as any big building.

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

How the visit works

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. Parking around Sompting is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  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.

Before we arrive

  • Move anything stored near the joints
  • Let us know about stairs, lifts or work at height
  • Plan for the work area to be out of bounds to pets and children

When to call us in Sompting

Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

Any of these means the joints need attention:

  • Damaged fire sealant left by other trades
  • Joints picked up in a fire-stopping survey
  • Gaps filled with a product that isn’t fire-rated
  • Holes left by a change of layout

For site and facilities teams at buildings such as Sompting Village Primary School, fire-stopping around service openings should be restored whenever new services go in.

What your quote should include

  • What product goes in the joint
  • How long to leave it before use
  • How the joint is cleaned and prepared
  • The length of the guarantee

FAQs for Sompting

Can you do fire rated sealant in Sompting?

Yes, Sompting is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.

Will you come out to Sompting?

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.

I rent my home. Can I book you?

We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

Do you work in flats, HMOs and commercial buildings?

Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.

Do you do fire sealant around door frames?

Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door leaf and its hardware need a door specialist.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before resealing.

What’s the difference between intumescent and fire-rated sealant?

Intumescent means it swells when heated. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

Is standard sealant good enough for a fire gap?

No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.

When it isn’t the sealant

New sealant can’t fix everything, and we will tell you before work begins. Sealant will not put right:

  • Assessing a building’s fire safety
  • Sign-off of the building, which sits with building control or your assessor
  • Fire doors that need new seals, closers or hardware

Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.

What fire rated sealant looks like in Sompting

For seaside hotels, guest houses and holiday lets around Sompting, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.

Community buildings like St Peter the Apostle are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Lancing station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Get damaged fire seals looked at promptly
  • Never patch a fire seal with standard sealant
  • Check risers, ceiling voids and cupboards during building checks
  • Ask which product was used before you paint

Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

Should I try it myself first?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
