How we handle fire rated sealant in Winkfield Street

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. If you have old fire sealant that has split or come away and seals cut through by electricians, plumbers or data installers, we can help, on pipe & cable gaps, plasterboard & masonry and service penetrations alike.

For a small place like Winkfield Street, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Your questions about fire rated sealant in Winkfield Street

Is Winkfield Street in your area for fire rated sealant?

Yes. We work across London and the South East, and Winkfield Street is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.

Can you help a landlord with a rental near Martins Heron station?

Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Should I try DIY first?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

How long does the job take?

As a guide, most jobs take from a few hours to a few days, depending on the number of gaps and the access. Larger jobs naturally take longer.

Can you seal over the old sealant?

No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Do you remove the old sealant?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.

Will we have a record of what was sealed?

Yes. You get a list of where we worked and what we used.

Fire rated sealant in Winkfield Street: 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.

Community buildings like Church of St Mary are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

What affects the cost of fire rated sealant

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

  • Working hours on commercial sites
  • The amount of work
  • How easy the joints are to reach
  • The product the joint needs

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

What to tell us for a quote

Before you ask for a quote, have a think about:

  • The problem you’ve noticed
  • The rough size of the job
  • Any previous sealing or DIY work
  • Photos by email, if that is easy

Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

What we do, step by step

We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Winkfield Street, the journey is planned in advance: 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. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your records.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Mention any parking rules near the property
  • Keep children and pets away from the work area

Honest limits

We won’t take on work that will not last, so these are the limits:

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

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Joints and surfaces we work on

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

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Work for landlords, hotels and businesses

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

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

When to call us in Winkfield Street

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

Look out for these signs:

  • Cracked or shrunken fire-rated sealant
  • Open holes round services passing through fire walls
  • Ordinary sealant used where a fire-rated product was needed
  • Door frames with gaps between frame and wall

For landlords with property near Martins Heron station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Different surfaces, different methods

Door frames

We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist, and we’ll say if we spot a problem with them.

Linear gaps

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