Fire rated sealant near Gospel Oak

Fire rated sealant in Gospel Oak

We can work through a building room by room or floor by floor. That record is useful for your files and for whoever looks at the building next. We’re often asked to deal with open joints along the top of partitions and gaps filled with a product that isn’t fire-rated, on linear gaps, door frames and flats & HMOs.

London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Gospel Oak, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.

Each job carries a 12-month guarantee, whatever its size.

Fire rated sealant around Gospel Oak

Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

If you look after a church, hall or community building such as Highgate Road Chapel, gaps around pipes and cables are worth checking after any building work there. Rented homes near Gospel Oak station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What we are called out for in Gospel Oak

Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

If you can see any of these, it’s time to have the joints looked at:

  • Fire seals that have cracked with movement
  • Gaps where walls meet ceilings or slabs
  • Gaps left after a refit or conversion
  • Open gaps behind door architraves

Gospel Oak is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

How we quote for fire rated sealant

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • How many areas need sealing
  • Whether the work is at height
  • Whether old sealant or filler has to be cut out
  • Working hours on commercial sites

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we need to know

There’s no need for technical detail. It helps if you can tell us:

  • Roughly how big the job is
  • Access, such as stairs, a lift or height
  • Where the property is
  • What’s wrong with the joints now

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.

Looking after it afterwards

Aftercare is simple, and it makes a real difference:

  • Check risers, ceiling voids and cupboards during building checks
  • Get damaged fire seals looked at promptly
  • Check whether a sealant can be painted before decorating over it
  • Allow for resealing whenever new services are run

Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.

How the job changes by surface

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each.

The process

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It normally takes from a few hours to a few days, depending on the number of gaps and the access. In a London area like Gospel Oak, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Finally, we list where we worked and what we used, for your records.

How to prepare

  • Tell us about any water getting in
  • Tell us if parking is tricky
  • Mention if the joints have been sealed before

Advice

Gospel Oak: your questions answered

Do you work in hotels near Gospel Oak?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Can parking be tricky for a visit in Gospel Oak?

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 rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

Is there any odour?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

What information do you need?

The location, the problem and the rough size of the job. If you can, email a few photos.

Will it make a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Is the work guaranteed?

Yes. Every job comes with our one-year guarantee.

Is standard sealant good enough for a fire gap?

No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service, or ask us to do it.

Why it’s worth doing now in Gospel Oak

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. In a flat in Gospel Oak, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

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

  • Neat joints and a tidy finish
  • 180+ five-star Google reviews
  • Anti-fungal silicone where joints get wet

Landlords, agents and businesses in Gospel Oak

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
