About our fire rated sealant in Tatsfield

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We work on pipe & cable gaps, linear gaps and plasterboard & masonry, and the jobs we see most are new service routes left unsealed after building work and joints picked up in a fire-stopping survey.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Tatsfield can’t close.

You get a one-year guarantee, the same in Tatsfield as everywhere else we work.

Workplaces and buildings in Tatsfield

Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. 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 work to the specification you’re given, installing the product to its tested details.

Tatsfield is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For buildings such as Church of St Mary the Virgin, service openings in its walls need the right fire-rated sealant, as in any building.

When to call us in Tatsfield

Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.

These are the problems we’re asked about most:

  • Open joints along the top of partitions
  • Gaps filled with a product that is not fire-rated
  • Cracked or shrunken fire-rated sealant
  • Seals cut through by electricians, plumbers or data installers

If you look after a building such as Charles Darwin School, service openings in fire-resisting walls need checking after any refurbishment.

What to look for in a quote

  • When the joint can take water or movement
  • Are they insured?
  • How hidden problems are handled
  • Which sealant they’ll use, and why

Choosing a sealant specialist

Landlord and commercial work in Tatsfield

Landlords and agents in Tatsfield can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

When it isn’t the sealant

Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Large holes that need a different fire-stopping system
  • Issuing a fire rating or certificate for a building
  • Fire risk assessments, which need a qualified assessor

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Joints and surfaces we work on

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

Common questions in Tatsfield

Do you work for landlords with property near Oxted station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.

Can parking be tricky for a visit in Tatsfield?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.

Are you fully insured?

Yes. We are fully insured for domestic and commercial work.

Should I try DIY first?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

What does intumescent mean?

Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

Do you guarantee your work?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.

Will it make a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before resealing.

DIY sealant or a professional job?

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

How the job changes by surface

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail.

How we quote for fire rated sealant

We quote each job individually. These are the things that affect it:

  • Any mould that needs treating
  • The number of rooms or windows
  • Any working-time requirements on site
  • The product the joint needs

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

What to tell us for a quote

To make quoting easier, let us know:

  • A few pictures by email, if you can
  • Where the job is, and your postcode
  • How many joints, rooms or windows are involved
  • Any access issues, like height or stairs

We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.

What happens on the day

At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  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. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

How to prepare

  • Clear items away from the joints we’re working on
  • Tell us about any water getting in
  • Tell us about access, such as stairs, a lift or high-level joints

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or send us an email.
