Fire rated sealant in Harestock

Why deal with it now?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. In an older home around Harestock, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

Combining jobs into one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.

Surface by surface

Door frames

We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist, and we’ll say if we spot a problem with them.

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.

What happens on the day

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on how many gaps there are, and the area is left clean. For a job in Harestock, 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 go through the gaps on your list or survey and check each one’s size and substrate.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

Before we arrive

  • Keep pets and children clear of the area while we work
  • Mention any sign-in or site rules at work premises
  • Clear items away from the joints we’re working on

When to call us in Harestock

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it is not fire-rated.

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

  • Door frames with gaps between frame and wall
  • Standard silicone or caulk in a fire-stopping gap
  • Fire seals that have cracked with movement
  • Open joints along the top of partitions

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

Choosing a sealant specialist

For landlords and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Harestock questions

Is Harestock within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you work for landlords with property near Winchester station?

Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.

Where do you work from?

We work from Crawley. Our applicators cover Harestock.

Can you quote for more than one area?

Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

How long does fire rated sealant take?

Typically it takes a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer, and we will tell you how long to expect.

Is the work guaranteed?

Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.

Do I have to be there?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.

Fire rated sealant around Harestock

There are hotels and other places to stay in and around Harestock. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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.

Community buildings like Saint Barnabas are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Rented homes near Winchester station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How we quote for fire rated sealant

You’ll get a clear quote before any work starts. It’s based on:

  • The type of sealant required
  • Whether the work is at height
  • Any working-time requirements on site
  • The amount of work

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

Asking for a quote

When you call or email, these details help:

  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved
  • Where the property is
  • Pictures of the joints, sent by email

Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.

Should I try it myself first?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
