Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you are dealing with fire stopping disturbed by later work and open holes round services passing through fire walls, we can help, whatever the surface.

For holiday lets, converted business premises or a community building near Fifield, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

What we are called out for in Fifield

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.

The most common problems we see are:

  • Sealant items on a fire risk assessment action list
  • Fire stopping disturbed by later work
  • Cracked or shrunken fire-rated sealant
  • Gaps filled with a product that is not fire-rated

Letting a property close to Maidenhead station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Choosing a sealant specialist

What happens on the day

Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on how many gaps there are. In a small place like Fifield, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • On commercial sites, let us know about site rules
  • Let us know about parking restrictions
  • Move anything stored near the joints

What sealant work can’t fix

To be straight with you, there are a few things sealant won’t fix:

  • A wall that isn’t a fire-resisting element to begin with
  • Issuing a fire rating or certificate for a building
  • Big openings where sealant alone isn’t the tested solution

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

Where we work in Fifield

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

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Plan fire stopping into any work that goes through walls or floors
  • Tell trades working in the building that fire seals must be put back
  • Check risers, ceiling voids and cupboards during building checks
  • Don’t fill fire-stopping gaps with ordinary foam or silicone

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

FAQs for Fifield

I let a flat near Maidenhead station. Can you help?

Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.

Can you do fire rated sealant in Fifield?

Yes, Fifield is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.

Are you ARBOMaster approved?

Yes. We’re an ARBOMaster approved applicator.

What do you put in the joint?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Can you seal over the old sealant?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Can you tell me how many minutes the seal will last?

We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.

How long does fire rated sealant take?

That depends on how much there is to do, but most jobs take from a few hours to a few days, depending on the number of gaps and the access. We’ll tell you when we quote.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Commercial buildings in Fifield

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

Managing a site like Braywood CofE First School? Then service openings in fire-resisting walls need checking after any refurbishment. For buildings such as All Saints, gaps around pipes and cables are worth checking after any building work there.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

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, and the work is guaranteed for a year.

What the job involves on each surface

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and the locations noted.

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
