Trusted fire rated sealant in Bushey

Fire rated sealant for homes and businesses in Bushey

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. Typical jobs include seals cut through by electricians, plumbers or data installers and holes left by a change of layout, across pipe & cable gaps, flats & HMOs and door frames.

In a town like Bushey, commercial work can mean offices, shops, schools, surgeries or small business units. All of them have washroom and kitchen joints, and many have fire-rated joints around pipes and cables.

You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

How it works

Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes from a few hours to a few days, depending on the number of gaps and the access. Parking in a town like Bushey is usually straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.

  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 gap cleaned.
  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 records.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Try not to wet indoor joints just before the visit
  • Let us know about earlier repairs to the joints

Keeping the joints in good condition

So the new joints stay in good condition:

  • Keep the record of products and locations with your fire safety documents
  • Check risers, ceiling voids and cupboards during building checks
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Don’t paint over fire sealant until it has cured

Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.

A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.

How we quote for fire rated sealant

We quote each job individually. This is what makes a difference:

  • Access and height
  • Whether old sealant or filler has to be cut out
  • Any working-time requirements on site
  • How many rooms, windows or areas are involved

Commercial jobs are quoted on the same basis as homes: 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 go through it with you.

What we need to know

What to tell us when you ask for a quote:

  • Pictures of the joints, sent by email
  • If it’s domestic, commercial or a hotel
  • Access, such as stairs, a lift or height
  • How many joints, rooms or windows are involved

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Why deal with it now?

Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. In a family home in Bushey, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Left alone, that means rot, damp and a bigger repair.

What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

Questions from Bushey

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

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.

Is there a guarantee on fire rated sealant in Bushey?

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

Should I try DIY first?

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

Can you tell me which gaps need fire stopping?

No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.

What do you need from me for a quote?

Let us know what needs doing and where, with photos by email if possible. If we need more, we will ask.

Which products do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

How long does the job take?

That depends on the amount of work, but as a guide it takes a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.

What fire rating will the seal have?

That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it with a record of each location.

Signs you need fire rated sealant in Bushey

In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.

The most common problems we see are:

  • Gaps where walls meet ceilings or slabs
  • Joints picked up in a fire-stopping survey
  • Fire stopping disturbed by later work
  • Fire seals that have cracked with movement

If you look after a church, hall or community building such as Congregational Church, service openings in its walls need the right fire-rated sealant, as in any building.

Questions to ask before you book

  • What happens if they find a problem under the old sealant
  • How the surfaces are prepared before sealing
  • The length of the guarantee
  • What insurance they hold

Commercial buildings in Bushey

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Schools such as Little Reddings Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. For landlords with property near Bushey station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard for the gap we are sealing.
