About our fire rated sealant in Hyde

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. Common call-outs are for open joints along the top of partitions and open gaps behind door architraves, on pipe & cable gaps, service penetrations and linear gaps.

Work in a small place like Hyde is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.

We stand behind the work with a one-year guarantee.

How the visit works

Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Hyde, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • Keep children and pets away from the work area
  • Mention if the joints have been sealed before

Aftercare tips

Good habits help new joints last longer. Our tips:

  • Ask every contractor to reseal any fire stopping they disturb
  • Report cracked or damaged seals as soon as you notice them
  • Include fire stopping when you schedule refits
  • Do not fill fire-stopping gaps with ordinary foam or silicone

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.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

When to call us in Hyde

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.

Signs it’s time to call us include:

  • Ordinary sealant used where a fire-rated product was needed
  • New service routes left unsealed after building work
  • Gaps around pipes and cables through fire-resisting walls
  • Open gaps behind door architraves

Managing a site like Hyde Church of England Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

What your quote should include

  • What happens if they find a problem under the old sealant

  • What insurance they hold

Why it’s worth doing now in Hyde

Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we will tell you. Where a wall is exposed, as many are in small places like Hyde, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

Why book with us

  • Tidy, careful work
  • Rated 4.9 stars on Google

Commercial buildings in Hyde

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.

For buildings such as Church of the Holy Ascension, service openings in its walls need the right fire-rated sealant, as in any building.

When it isn’t the sealant

Before booking, it’s worth knowing the limits:

  • Problems with the door itself rather than the gap around the frame
  • Large holes that need a different fire-stopping system
  • Walls or floors that weren’t built to resist fire

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

What we seal

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

Surface by surface

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard for each gap size.

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 we start so residents know what to expect.

Common questions in Hyde

Do you cover Hyde for fire rated sealant?

Yes, Hyde is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.

What guarantee comes with fire rated sealant in Hyde?

Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

Do you seal gaps around fire door frames?

Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door, its seals and closer are for a door specialist.

Can I use normal mastic around a pipe through a fire wall?

No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.

Is it messy?

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

Do you take out the old sealant first?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Do you certify the fire stopping?

We do not issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.

Can you match the sealant colour?

In most cases you can choose. We’ll explain which colours are available and agree one before work begins.

Can I do it myself?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
