DIY sealant or a professional job?

A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

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

Fire rated sealant for homes and businesses in Polstead

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. If you are dealing with gaps where walls meet ceilings or slabs and damaged fire sealant left by other trades, we can put it right, whatever the surface.

Work in a small place like Polstead is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

What affects the quote in Polstead

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

  • Mould in or behind the old joints
  • Whether old sealant or filler has to be cut out
  • The amount of work
  • How many rooms, windows or areas are involved

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email.

Asking for a quote

To help us quote quickly, please include:

  • Where the job is, and your postcode
  • If someone has resealed it before
  • Whether it’s a home or a business
  • How we’d reach the joints

We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or email us.

When to call us in Polstead

Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.

Keep an eye out for any of the following:

  • New service routes left unsealed after building work
  • Ordinary sealant used where a fire-rated product was needed
  • Joints picked up in a fire-stopping survey
  • Fire stopping disturbed by later work

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

Before you book anyone

  • Whether all the old sealant comes out first
  • Which colour the sealant will be
  • Are they insured?
  • Which sealant they’ll use, and why

The process

Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Polstead, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  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. Locations and products are noted so you have them on file.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Mention any parking rules near the property
  • Move anything stored near the joints

Leave it or put it right?

An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. Older cottages and farmhouses around Polstead can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
