Trusted fire rated sealant in Plaistow

Why deal with it now?

Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. Where a wall is exposed, as many are in small places like Plaistow, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Common questions in Plaistow

Is there a guarantee on fire rated sealant in Plaistow?

All our work, in Plaistow and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Can you do fire rated sealant in Plaistow?

Yes. Our work covers London and the South East, and Plaistow is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.

Do you hold any approvals?

Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

Is there any odour?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

Can you give us a record of the work?

Yes. We record the locations we have sealed and the products used for your files.

Do you remove the old sealant?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

Can you match the sealant colour?

Usually, yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Photograph sealed gaps before they’re covered up
  • Report cracked or damaged seals as soon as you notice them
  • Do not paint over fire sealant until it has cured
  • Never patch a fire seal with standard sealant

Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.

A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.

Do you need fire rated sealant in Plaistow?

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.

Signs it’s time to call us include:

  • Unsealed gaps where pipes and cables go through a wall
  • Cracked or shrunken fire-rated sealant
  • Open joints along the top of partitions
  • Unsealed gaps around fire door frames

If you look after a church, hall or community building such as Holy Trinity Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Questions to ask before you book

  • What preparation is included
  • How long to leave it before use
  • How much experience the applicator has
  • Whether they seal over old material or remove it

What affects the quote in Plaistow

We quote each job individually. These are the things that affect it:

  • The number of rooms or windows
  • The type of sealant required
  • Any working-time requirements on site

Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

  • The problem you’ve noticed
  • The rough size of the job

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 work to the specification you are given, installing the product to its tested details.

Managing a site like Plaistow and Kirdford Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

Can I do it myself?

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.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

What happens on the day

When we arrive, we look over the joints with you first. Surfaces next to the work are protected before work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Plaistow needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your records.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Clear the area around the work
  • On commercial sites, let us know about site rules
