Should I try it myself first?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Fire rated sealant in Bricket Wood, done properly

Bigger jobs can be worked through in stages, flat by flat or floor by floor, with each location and product recorded. It gives you a list to keep with the building’s fire safety documents.

Keeping the joints in good condition

Simple care keeps the joints in good condition. Our advice:

  • Never patch a fire seal with standard sealant
  • Ask which product was used before you paint
  • Report cracked or damaged seals as soon as you notice them
  • Store the list of sealed gaps with your building paperwork

Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.

An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

What happens on the day

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building. For a job in Bricket Wood, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  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. 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.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • For business premises, tell us about site rules or sign-in
  • Move anything stored near the joints

What the job involves on each surface

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified, flat by flat if needed.

Will it make a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

Should I try DIY first?

Workplaces and buildings in Bricket Wood

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Rented homes near Bricket Wood station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Managing a site like Mount Pleasant Lane Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Church of All Saints, gaps around pipes and cables are worth checking after any building work there.
