Workplaces and buildings in North Boarhunt

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.

Community buildings like Church of the Holy Trinity are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. For landlords with property near Portchester station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Fire rated sealant in North Boarhunt

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We’re often asked to deal with open holes round services passing through fire walls and new service routes left unsealed after building work, on pipe & cable gaps, linear gaps and door frames.

In a village or hamlet like North Boarhunt, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Our work is backed for twelve months, in North Boarhunt and everywhere else we cover.

Signs you need fire rated sealant in North Boarhunt

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

Common reasons people contact us include:

  • Gaps filled with a product that is not fire-rated
  • Gaps where walls meet ceilings or slabs
  • Sealant items on a fire risk assessment action list
  • Cracked or shrunken fire-rated sealant

Schools such as Newtown Soberton Infant School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

How it works

We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as North Boarhunt, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. 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 files.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Mention any leaks or damp you’ve noticed
  • Clear items away from the joints we are working on

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or email us.

Landlord and commercial work in North Boarhunt

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.

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

What affects the cost of fire rated sealant

We do not publish a price list, because no two jobs are the same. What we look at:

  • Which sealant suits the joint
  • How many areas need sealing
  • Whether the work is at height
  • How much old sealant there is and how hard it is to remove

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

Helping us quote

What to tell us when you ask for a quote:

  • Where the property is
  • Roughly how big the job is
  • Whether it’s a home or a business
  • The problem you’ve noticed

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

What the job involves on each surface

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first.

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.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Honest limits

It helps to know what we can’t do:

  • Doors that aren’t fire doors in the first place
  • Deciding what fire stopping a building needs
  • Construction that does not provide fire resistance on its own

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

Yes, North Boarhunt is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.

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

Will there be a smell?

Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

What information do you need?

The location, the problem and the rough size of the job. Photos by email help too.

Do you take on fire stopping in schools and offices?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.

Do you take out the old sealant first?

Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

Are you insured?

Yes, we are fully insured for every job we do.

Do you hold any approvals?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
