Workplaces and buildings in Andover Down

How we handle fire rated sealant in Andover Down

A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That detail is what we take care over, gap by gap. Common call-outs are for gaps left after a refit or conversion and seals cut through by electricians, plumbers or data installers, on pipe & cable gaps, plasterboard & masonry and door frames.

Somewhere as small as Andover Down, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

DIY sealant or a professional job?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Common problems we fix in Andover Down

In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.

The most common problems we see are:

  • Open holes round services passing through fire walls
  • Gaps where walls meet ceilings or slabs
  • Gaps filled with a product that isn’t fire-rated
  • Open gaps behind door architraves

If you look after a building such as Pilgrims' Cross CofE Aided Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

How to choose a mastic man

Why act early in Andover Down

For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. In a small place like Andover Down, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

  • A 12-month guarantee on all work
  • 4.9 on Google from 180+ five-star reviews
  • Any old sealant cut out fully, not covered over

Andover Down: your questions answered

Can you do fire rated sealant in Andover Down?

Yes, Andover Down is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.

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

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.

Are you an approved applicator?

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

Can you do several jobs on one visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Is it messy?

Very little: the area around the joints is protected first, and we tidy up before we go.

Can you tell me which gaps need fire stopping?

No. That’s for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.

Do you certify the fire stopping?

We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.

Do you remove the old sealant?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

What we can’t put right

We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:

  • Construction that does not provide fire resistance on its own
  • Doors that are not fire doors in the first place
  • Issuing a fire rating or certificate for a building

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.

What affects the quote in Andover Down

Jobs vary more than people expect. What affects the quote:

  • Working hours on commercial sites
  • Whether there’s mould to deal with
  • The type of sealant required
  • The old material and how stubborn it is

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

What we need to know

Photos help, but a description is a good start. Please mention:

  • Whether it’s a home or a business
  • How many joints, rooms or windows are involved
  • Pictures of the joints, sent by email
  • Where the job is, and your postcode

If you are in Andover Down and need fire rated sealant, call 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before any work starts.

How the visit works

We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Andover Down, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

How to prepare

  • Move anything stored near the joints
  • Let us know if you’ve seen damp or leaks
  • Try not to wet indoor joints just before the visit
