Fire rated sealant for homes and businesses in Hampstead Garden Suburb
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. If you have holes left by a change of layout and unsealed gaps around fire door frames, we can put it right, on plasterboard & masonry, linear gaps and flats & HMOs alike.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Hampstead Garden Suburb cannot close.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

DIY sealant or a professional job?
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.
If you are set on DIY, put the effort into 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.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Check whether a sealant can be painted before decorating over it
- Include fire stopping when you schedule refits
- Tell trades working in the building that fire seals must be put back
- Keep the record of products and locations with your fire safety documents
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t and we will tell you which one you have.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
What we cannot put right
Sealant isn’t the answer to every problem, and we will tell you before any work starts. Sealant won’t put right:
- Walls or floors that weren’t built to resist fire
- Problems with the door itself rather than the gap around the frame
- Sign-off of the building, which sits with building control or your assessor
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.
Surfaces we seal
- Linear gaps
- Flats & HMOs
- Service penetrations
- Door frames
- Pipe & cable gaps
- Plasterboard & masonry
How we quote for fire rated sealant
Every job gets its own quote. These are the things that affect it:
- Mould in or behind the old joints
- The product the joint needs
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
What to tell us for a quote
You don’t need to know the technical terms. Just tell us:
- Where the property is
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- Any access issues, like height or stairs
Need a quote? Please ring 0345 464 0079 or send us an email with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.
