Fire rated sealant in Sipson

Fire rated sealant around Sipson

There are hotels and other places to stay in and around Sipson. 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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

If you look after a church, hall or community building such as Christ Church, service openings in its walls need the right fire-rated sealant, as in any building. As a London address, Sipson can be tricky for parking: let us know about parking bays, permits or a driveway. Schools such as Cherry Lane Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

About our fire rated sealant in Sipson

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. If you are dealing with old fire sealant that has split or come away and sealant items on a fire risk assessment action list, we can put it right, whatever the surface.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Sipson cannot close.

Your job is guaranteed for a year, as with all our work.

Landlords, agents and businesses in Sipson

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

FAQs for Sipson

Is parking a problem for a job in Sipson?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

I let a flat near West Drayton station. Can you help?

Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Do you work in Sipson?

Yes, we do. Our applicators work in Sipson.

How long will you be here?

A typical job takes anything from a few hours to several days, depending on how many gaps there are, including preparation and clearing up. We will confirm how long when we quote.

Do you work in flats, HMOs and commercial buildings?

Yes. We regularly work in flats, HMOs, schools and offices while they’re in use and we plan access around the people using them. Early starts or out-of-hours work can be arranged where it’s needed.

Do you seal gaps around fire door frames?

Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself.

Can you quote for more than one area?

Yes, we can. Several rooms, windows or areas can go on one quote.

Are you fully insured?

Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.

How the visit works

There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. In a London area like Sipson, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work
  • Let us know about parking restrictions

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or drop us an email.

Related advice

Why deal with it now?

Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing once someone inspects it. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Combining jobs into one visit generally makes better use of the time than several visits. We will give you a clear quote for the lot.

Take a look at what affects the cost and what customers say.

What the job involves on each surface

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail.

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard.

Quotes for fire rated sealant in Sipson

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

  • Access and height
  • When we can work, for business premises
  • The old material and how stubborn it is
  • The number and length of the joints

What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

What to tell us for a quote

To help us quote quickly, let us know:

  • Where the property is
  • What the problem is, such as mould, gaps, leaks or cracking
  • The type of property
  • The rough size of the job

For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work before giving you a price.

How to look after the new joints

Looking after new joints is easy, and it makes a real difference:

  • Check whether a sealant can be painted before decorating over it
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Tell trades working in the building that fire seals must be put back
  • Check risers, ceiling voids and cupboards during building checks

File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is generally a straightforward job.

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

A DIY attempt does not rule out a professional job. We cut it out and start again.
