The process

You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. In a small place like Selham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your files.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Let us know if you’ve seen damp or leaks
  • Plan for the work area to be out of bounds to pets and children

Advice

Fire rated sealant for homes and businesses in Selham

Deciding which gaps need fire stopping isn’t 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 open joints along the top of partitions and gaps left after a refit or conversion, on flats & HMOs, door frames and plasterboard & masonry.

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

A one-year guarantee comes as standard, so you’re covered after we have gone.

Landlord and commercial work in Selham

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Why it’s worth doing now in Selham

Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again when the building is next checked. Around Selham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

What you get with us

  • Tidy, careful work
  • Quality sealants from Arbo and Everbuild
  • Domestic, commercial and hotel work
  • Sanitary silicone with an anti-fungal additive in wet areas

When to call us in Selham

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.

The most common problems we see are:

  • Gaps around pipes and cables through fire-resisting walls
  • Gaps filled with a product that is not fire-rated
  • Gaps where walls meet ceilings or slabs
  • Sealant items on a fire risk assessment action list

If you look after a church, hall or community building such as Church of St James, gaps around pipes and cables are worth checking after any building work there.

10 questions to ask before booking

DIY versus a professional finish

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Your questions about fire rated sealant in Selham

Is there a guarantee on fire rated sealant in Selham?

All our work, in Selham and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.

Do you cover smaller places like Selham?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you take out the old sealant first?

Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

Do you seal gaps around fire door frames?

Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door, its seals and closer are for a door specialist.

Do you provide details of the products used?

Yes. You get a list of where we worked and what we used to keep with your fire safety documents.

Should I try DIY first?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

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

No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.

What does fire rated sealant cost?

We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

How we quote for fire rated sealant

The price is agreed before any work begins. It’s based on:

  • The size of the job
  • The old material and how stubborn it is
  • Whether there’s mould to deal with
  • When we can work, for business premises

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.

What we need to know

What to tell us when you ask for a quote:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it’s a home or a business
  • Access, such as stairs, a lift or height
  • Whether it has been sealed before

For a quote, call 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before we start.

Fire rated sealant in Selham: local notes

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, 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.

In and around Selham, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

How to look after the new joints

Good habits help new joints last longer. Our tips:

  • File the fire-stopping record where your assessor can find it
  • Tell trades working in the building that fire seals must be put back
  • Include fire stopping when you schedule refits
  • Include hidden areas like risers in routine checks

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.
