Fire rated sealant in Bockmer End

What we do, step by step

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Bockmer End needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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. 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 sign-in or site rules at work premises

About our fire rated sealant in Bockmer End

A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That detail is what we take care over, gap by gap. Typical jobs include fire seals that have cracked with movement and joints picked up in a fire-stopping survey, on plasterboard & masonry, flats & HMOs and door frames.

For holiday lets, converted business premises or a community building near Bockmer End, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Your questions about fire rated sealant in Bockmer End

Can you help a landlord with a rental near Marlow station?

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

Do you cover smaller places like Bockmer End?

Yes, Bockmer End is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can you tell me how many minutes the seal will last?

That is not something we state or certify. Your specification sets the requirement, and we apply a product tested for it, recording the locations and products.

Do I need to be at home?

That depends on where the joints are. Inside work needs someone to give us access.

Is there a guarantee?

Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.

How long does fire rated sealant take?

That depends on the amount of work, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We’ll tell you when we quote.

Will there be a smell?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Do you carry out fire risk assessments?

No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.

What we’re called out for in Bockmer End

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.

The problems people generally mention when they call are:

  • Joints picked up in a fire-stopping survey
  • Open holes round services passing through fire walls
  • Cracked or shrunken fire-rated sealant
  • Gaps filled with a product that is not fire-rated

Schools such as Danesfield School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

What your quote should include

  • The length of the guarantee
  • How the colour is chosen
  • Who turns up on the day
  • Which sealant they’ll use, and why

How to choose a mastic man

Can I do it myself?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

For landlords and businesses

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

How we quote for fire rated sealant

Your quote is based on your job. We look at:

  • Whether old sealant or filler has to be cut out
  • The number and length of the joints
  • The number of rooms or windows
  • How easy the joints are to reach

Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Helping us quote

Before you ask for a quote, have a think about:

  • If it’s domestic, commercial or a hotel
  • What the problem is, such as mould, gaps, leaks or cracking
  • Photos by email, if that is easy
  • How we’d reach the joints

Every job is quoted individually. Simply ring 0345 464 0079 or drop us an email and describe the job and send pictures if you have them.

What fire rated sealant looks like in Bockmer End

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. There are hotels and other places to stay in and around Bockmer End. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

Community buildings like Church of St Peter and St Paul are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Marlow station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Aftercare tips

So the new joints stay in good condition:

  • Check whether a sealant can be painted before decorating over it
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Ask every contractor to reseal any fire stopping they disturb
  • Flag any open gap you spot round a pipe or cable

Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

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

Honest limits

Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:

  • Certifying a building or signing off its fire safety
  • Big openings where sealant alone is not the tested solution
  • Problems with the door itself rather than the gap around the frame

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