Fire rated sealant in Fulwell

Workplaces and buildings in Fulwell

Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. Fulwell 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.

For buildings such as St Michael's, older buildings that have had new heating or wiring often have service gaps worth checking. As a London address, Fulwell can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

When it is not the sealant

In fairness, there are a few things sealant will not fix:

  • Fire doors that need new seals, closers or hardware
  • Construction that doesn’t provide fire resistance on its own
  • Deciding what fire stopping a building needs

If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

Joints and surfaces we work on

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

The process

On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a handful of gaps, and longer for a whole building, including the tidy-up. In Fulwell, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Let us know about earlier repairs to the joints
  • For business premises, tell us about site rules or sign-in

Related advice

What we are called out for in Fulwell

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.

The most common problems we see are:

  • Open holes round services passing through fire walls
  • Fire seals that have cracked with movement
  • Gaps where walls meet ceilings or slabs
  • Gaps left after a refit or conversion

Letting a property close to Fulwell station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Questions to ask before you book

  • Whether they’re fully insured
  • How much experience the applicator has
  • When the joint can take water or movement
  • Is the old sealant removed completely?

10 questions to ask before you book

Questions from Fulwell

Do you work in hotels near Fulwell?

Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Is parking a problem for a job in Fulwell?

Parking in Fulwell, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Do you guarantee your work?

Yes. All our work carries our one-year guarantee.

What do you need from me for a quote?

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

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Will you leave a mess?

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

What sealant do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

I rent my home. Can I book you?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

Landlord and commercial work in Fulwell

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

What affects the cost of fire rated sealant

For a quick quote, just ask. The main things that affect it are:

  • How many rooms, windows or areas are involved
  • Mould in or behind the old joints
  • The product the joint needs
  • The size of the job

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

What we need to know

When you contact us, these details help:

  • Whether it’s a home or a business
  • What the problem is, such as mould, gaps, leaks or cracking
  • Any previous sealing or DIY work
  • The address or postcode of the job

For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. You’ll have a clear quote before we start.

How to look after the new joints

After the cure time, these simple habits help:

  • Ask every contractor to reseal any fire stopping they disturb
  • Report cracked or damaged seals as soon as you notice them
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Take photos of fire stopping before ceilings or boxing go back

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.

An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

Why act early in Fulwell

Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Fulwell, the repair is bigger than a sealant job.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
