Why act early in Magham Down

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Around Magham Down, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What we do, step by step

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Magham Down, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Where the tested detail needs backing or fill, we fit it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Finally, we list where we worked and what we used, for your records.

What the job involves on each surface

Flats and HMOs

In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before work begins to keep disruption down.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each and we flag any that need another system.

Work for landlords, hotels and businesses

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 go on one 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.

Commercial buildings in Magham Down

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 Polegate station, any gap left by new services in shared walls should be closed with a fire-rated product.

Do you need fire rated sealant in Magham Down?

Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

Keep an eye out for these signs:

  • Linear gaps at the head of walls
  • Gaps around pipes and cables through fire-resisting walls
  • Fire stopping disturbed by later work
  • Gaps filled with a product that isn’t fire-rated

If you look after a building such as Hailsham Community College, fire-stopping around service openings should be restored whenever new services go in.

Questions to ask before booking

  • Who turns up on the day
  • Whether the sealant suits the joint
  • The length of the guarantee
  • Whether they’re fully insured

10 questions to ask before booking

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Keep photos of seals that will be hidden
  • Get damaged fire seals looked at promptly
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Make resealing part of every contractor’s brief

Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.

A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so you can show it was dealt with.

Magham Down: your questions answered

Will you come out to Magham Down?

Yes, Magham Down is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you cover Magham Down for fire rated sealant?

Yes. We work across London and the South East, and Magham Down is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Do you seal gaps around fire door frames?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself and we will tell you if we spot problems with the door.

Can new sealant go over the old?

No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.

What’s the difference between intumescent and fire-rated sealant?

Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all.

Are you fully insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

I rent my home. Can I book you?

Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
