About our fire rated sealant in Wivelsfield Green

Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. If you’re dealing with open gaps behind door architraves and old fire sealant that has split or come away, we can help, on pipe & cable gaps, linear gaps and service penetrations alike.

Somewhere as small as Wivelsfield Green, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Landlord and commercial work in Wivelsfield Green

We regularly work with letting and managing agents. Tell us the address, the job and how access works.

If you manage several properties in or around Wivelsfield Green, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

What sealant work can’t fix

A few problems are outside what sealant work can do:

  • Big openings where sealant alone is not the tested solution
  • Fire risk assessments, which need a qualified assessor
  • Problems with the door itself rather than the gap around the frame

If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Fire rated sealant in Wivelsfield Green: local notes

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.

For buildings such as Ote Hall Chapel, service openings in its walls need the right fire-rated sealant, as in any building. Letting a property close to Wivelsfield station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as Wivelsfield Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Surface by surface

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run.

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

What we do, step by step

There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. In a small place like Wivelsfield Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Clear the area around the work
  • Let us know if you’ve seen damp or leaks

What affects the cost of fire rated sealant

Your quote is based on your job. We take into account:

  • The product the joint needs
  • Access and height
  • The number and length of the joints
  • How many areas need sealing

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Asking for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Any previous sealing or DIY work
  • Pictures of the joints, sent by email
  • What’s wrong with the joints now
  • If it’s domestic, commercial or a hotel

For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we will explain what’s involved.

How to look after the new joints

No joint lasts for ever, but care makes a real difference. Our tips:

  • Include hidden areas like risers in routine checks
  • Make resealing part of every contractor’s brief
  • Include fire stopping when you schedule refits
  • File the fire-stopping record where your assessor can find it

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.

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