Need fire rated sealant in Stonebridge Park?

What the job involves on each surface

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length so there are no open sections left.

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we will tell you.

How we handle fire rated sealant in Stonebridge Park

We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you are dealing with ordinary sealant used where a fire-rated product was needed and new service routes left unsealed after building work, we can help, 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 Stonebridge Park can’t close.

There’s a 12-month guarantee on every job, large or small.

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

How to look after the new joints

A little care helps the new joints last. We recommend:

  • Tell trades working in the building that fire seals must be put back
  • Allow for resealing whenever new services are run
  • Never patch a fire seal with standard sealant
  • Keep the record of products and locations with your fire safety documents

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

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Fire rated sealant around Stonebridge Park

There are hotels and other places to stay in and around Stonebridge Park. Hotel work can be planned room by room, with out-of-hours working where needed. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.

Rented homes near Stonebridge Park station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as St Michael the Archangel, older buildings that have had new heating or wiring often have service gaps worth checking. As a London address, Stonebridge Park can be tricky for parking: let us know about parking bays, permits or a driveway.

For landlords and businesses

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

What sealant work cannot fix

We’ll always be straight with you, so here’s what new sealant will not do:

  • Deciding what fire stopping a building needs
  • Issuing a fire rating or certificate for a building
  • Walls or floors that weren’t built to resist fire

If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

What we seal

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

Quotes for fire rated sealant in Stonebridge Park

The price is agreed before any work begins. It takes into account:

  • The old material and how stubborn it is
  • Whether there’s mould to deal with
  • The amount of work
  • Whether the work is at height

What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

Helping us quote

What to tell us when you ask for a quote:

  • If someone has resealed it before
  • What’s wrong with the joints now
  • A few photos by email, if you can
  • The type of property

If you are in Stonebridge Park and need fire rated sealant, ring 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.

Your questions about fire rated sealant in Stonebridge Park

Do you work in hotels near Stonebridge Park?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Can you help a landlord with a rental near Stonebridge Park station?

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

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Where do you work from?

Mr Mastic is based in Crawley. We cover Stonebridge Park and the rest of Greater London, along with the rest of our area.

Do I need to be at home?

If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.

Are you an approved applicator?

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

Can you tell me which gaps need fire stopping?

No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.

The process

We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on how many gaps there are, and we tell you how long to leave it before we go. In Stonebridge Park, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any leaks or damp you’ve noticed
  • Where the joints are inside, avoid wetting them before we arrive
