About our fire rated sealant in South Acton

We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. If you have joints picked up in a fire-stopping survey and ordinary sealant used where a fire-rated product was needed, we can put it right.

Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in South Acton.

A one-year guarantee comes with the work, just as it does everywhere we cover.

What fire rated sealant looks like in South Acton

South Acton has hotels and guest accommodation in and around it. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Rented homes near South Acton station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like Ark Acton Academy? Then service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Church of All Saints are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

What affects the quote in South Acton

We don’t publish a price list, because no two jobs are the same. The quote depends on:

  • Which sealant suits the joint
  • How many areas need sealing
  • When we can work, for business premises
  • The size of the job

Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

What we need to know

When you contact us, it’s useful to know:

  • How we’d reach the joints
  • The type of property
  • What’s wrong with the joints now
  • The rough size of the job

To get a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. You’ll have a clear quote before we start.

DIY versus a professional finish

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Surface by surface

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length.

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail, and we will tell you.

FAQs for South Acton

Can parking be tricky for a visit in South Acton?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

I let a flat near South Acton station. Can you help?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

What should I tell you?

Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.

Do you carry out fire risk assessments?

No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we’ll quote for the sealant work on it.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Do you offer different sealant colours?

Most of the time, yes. We’ll explain which colours are available and agree one before work begins.

Can I add another job to the visit?

Yes. More than one area can go on one quote.

Can I use normal mastic around a pipe through a fire wall?

No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed and we can apply it for you.

Landlord and commercial work in South Acton

In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.

What sealant work can’t fix

Some problems need a builder, plumber or other trade rather than us:

  • Deciding what fire stopping a building needs
  • Issuing a fire rating or certificate for a building
  • Construction that does not provide fire resistance on its own

If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Joints and surfaces we work on

  • Linear gaps
  • Flats & HMOs
  • Door frames
  • Service penetrations
  • Pipe & cable gaps
  • Plasterboard & masonry

Keeping the joints in good condition

A little care helps the new joints last. Our advice:

  • Ask which product was used before you paint
  • Include hidden areas like risers in routine checks
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Ask every contractor to reseal any fire stopping they disturb

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

What happens on the day

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. In South Acton, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is 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.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Plan for the work area to be out of bounds to pets and children
  • Try not to wet indoor joints just before the visit
