About our fire rated sealant in Wymering

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. Common call-outs are for open joints along the top of partitions and joints picked up in a fire-stopping survey, across flats & HMOs, service penetrations and linear gaps.

Commercial work around a smaller place like Wymering usually means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Fire rated sealant in Wymering: local notes

If you run a hotel, guest house or holiday let in a coastal place like Wymering, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.

For site and facilities teams at buildings such as Medina Primary School, fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Cosham station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Do you need fire rated sealant in Wymering?

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

It’s worth asking for a quote if you see:

  • Door frames with gaps between frame and wall
  • Seals cut through by electricians, plumbers or data installers
  • Unsealed gaps where pipes and cables go through a wall
  • Standard silicone or caulk in a fire-stopping gap

Community buildings like Church of St Peter and St Paul are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Before you book anyone

  • Is the old sealant removed completely?
  • Whether the sealant suits the joint
  • What insurance they hold
  • How the colour is chosen

When something else is needed

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

  • Assessing a building’s fire safety
  • A wall that is not a fire-resisting element to begin with
  • Big openings where sealant alone is not the tested solution

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

Surfaces we seal

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

How we quote for fire rated sealant

Jobs vary more than people expect. What affects the quote:

  • The type of sealant required
  • Whether there’s mould to deal with
  • How many rooms, windows or areas are involved
  • Access and height

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Asking for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Roughly how big the job is
  • Whether it has been sealed before
  • How we’d reach the joints
  • The problem you’ve noticed

There’s no standard price list. Instead, we give you a clear quote for your job. To arrange one, phone 0345 464 0079 or drop us an email.

Keeping the joints in good condition

How long the joints last depends on use and care. Here’s what we suggest:

  • Report cracked or damaged seals as soon as you notice them
  • Include hidden areas like risers in routine checks
  • Keep the record of products and locations with your fire safety documents
  • Check whether a sealant can be painted before decorating over it

File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.

Work for landlords, hotels and businesses

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.

We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.

The process

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It generally takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Wymering, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  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. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Finally, we list where we worked and what we used, for your records.

Before we arrive

  • Clear the area around the work
  • On commercial sites, let us know about site rules
  • Keep children and pets away from the work area

Advice

Can I do it myself?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

Wymering questions

Is Wymering within the area you cover?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Cosham station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.

Can new sealant go over the old?

No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Can you do several jobs on one visit?

Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Will the old sealant be removed?

Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.

How much does fire rated sealant cost in Wymering?

It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or email us with a short description of the job.

Do you do fire sealant around door frames?

Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself and we will tell you if we spot problems with the door.
