Fire rated sealant in Monken Hadley

How we handle fire rated sealant in Monken Hadley

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you are dealing with holes left by a change of layout and fire seals that have cracked with movement, we can put it right, whatever the surface.

In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Monken Hadley, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

There’s a 12-month guarantee on every job, whatever its size.

Why act early in Monken Hadley

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. 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.

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

The process

When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. The work usually takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Monken Hadley, parking and access are the things to plan: 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. 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

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any leaks or damp you’ve noticed
  • Let us know about parking restrictions

How we quote for fire rated sealant

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

  • How many rooms, windows or areas are involved
  • Any mould that needs treating
  • How much there is to do
  • How much old sealant there is and how hard it is to remove

What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Asking for a quote

Photos help, but a description is a good start. Try to tell us:

  • Access, such as stairs, a lift or height
  • The problem you’ve noticed
  • Whether it’s a home or a business
  • Where the job is, and your postcode

Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will take it from there.

FAQs for Monken Hadley

Can parking be tricky for a visit in Monken Hadley?

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 Hadley Wood station. Can you help?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.

Will there be a smell?

Sometimes, a little. It fades as the sealant cures.

Do you certify the fire stopping?

We don’t give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it with a record of each location.

What does fire rated sealant cost?

It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email with a short description of the job.

What do you put in the joint?

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

Can you seal over the old sealant?

No, because it fails. We remove every bit of old sealant first.

Can ordinary silicone be used in a fire-stopping gap?

No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.

Workplaces and buildings in Monken Hadley

Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

If you let a flat or house near Hadley Wood station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Monken Hadley CofE Primary School, fire-stopping around service openings should be restored whenever new services go in.

What sealant work cannot fix

Sealant is not the answer to every problem, and we will tell you before any work starts. Sealant won’t put right:

  • Problems with the door itself rather than the gap around the frame
  • Assessing a building’s fire safety
  • A wall that is not a fire-resisting element to begin with

Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before you book.

Surfaces we seal

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

Common problems we fix in Monken Hadley

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it isn’t a fire-rated seal.

Any of these means the joints need attention:

  • Holes left by a change of layout
  • Open holes round services passing through fire walls
  • Open joints along the top of partitions
  • Fire stopping disturbed by later work

As a London address, Monken Hadley can be tricky for parking: let us know about parking bays, permits or a driveway.

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

For landlords and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
