Fire rated sealant in Farnborough

Fire rated sealant for homes and businesses in Farnborough

Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment on buildings across Farnborough. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on pipe & cable gaps, flats & HMOs and service penetrations, and the jobs we see most are gaps flagged on a fire risk assessment and new service routes left unsealed after building work.

Shared washrooms take far more use than a home bathroom, and their sealant shows it, and fire-rated joints need restoring whenever new services are run through a wall. In Farnborough, timings are planned around the building.

A one-year guarantee comes as standard, so you’re covered after we have gone.

Questions from Farnborough

What guarantee comes with fire rated sealant in Farnborough?

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

Can you help a landlord with a rental near Farnborough Main station?

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

What do you need from me for a quote?

Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.

Can you fill the gap behind a fire door frame?

Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.

Do you hold any approvals?

Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

Can you give us a record of the work?

Yes. Every gap we seal is listed with the product used so it’s there for the next inspection.

Is there any odour?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and we’ll quote it together.

What happens on the day

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In Farnborough, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • Tell us about any previous sealing or DIY attempts
  • Tell us about any water getting in

Advice

For landlords and businesses

Letting agents and landlords in Farnborough can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Do you need fire rated sealant in Farnborough?

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common particularly when it was the last job before handover.

Most people get in touch when they notice one of these:

  • New service routes left unsealed after building work
  • Open gaps behind door architraves
  • Fire seals that have cracked with movement
  • Linear gaps at the head of walls

If you look after a church, hall or community building such as Church of St Christopher, gaps around pipes and cables are worth checking after any building work there.

What to look for in a quote

  • How the joint is cleaned and prepared
  • What guarantee comes with the work
  • Which colour the sealant will be
  • Whether all the old sealant comes out first

Choosing a sealant specialist

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

How to look after the new joints

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

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Ask every contractor to reseal any fire stopping they disturb
  • Take pictures of fire stopping before ceilings or boxing go back
  • Don’t paint over fire sealant until it has cured

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t and we will tell you which one you have.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Fire rated sealant in Farnborough: 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, 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.

For site and facilities teams at buildings such as Tower Hill Primary School, fire-stopping around service openings should be restored whenever new services go in. Rented homes near Farnborough Main station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What affects the quote in Farnborough

Your quote is based on your job. We look at:

  • The size of the job
  • How much old sealant there is and how hard it is to remove
  • The type of sealant required
  • Working hours on commercial sites

What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before we start.

Helping us quote

Photos help, but a description is a good start. Try to tell us:

  • Where the property is
  • How we’d reach the joints
  • What the problem is, such as mould, gaps, leaks or cracking
  • How many joints, rooms or windows are involved

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

What the job involves on each surface

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.

Plasterboard walls

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