Fire rated sealant for homes and businesses in East Dulwich
Until it’s heated, intumescent sealant behaves like an ordinary sealant; 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 follow the tested detail for each one. We work on plasterboard & masonry, flats & HMOs and door frames, and the jobs we see most are cracked or shrunken fire-rated sealant and gaps where walls meet ceilings or slabs.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in East Dulwich needs to stay open, work can be planned outside normal hours.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Construction that does not provide fire resistance on its own
- Issuing a fire rating or certificate for a building
- Fire doors that need new seals, closers or hardware
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What the job involves on each surface
Flats and HMOs
Conversions generally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and record where they are.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each, and tell you if sealant alone isn’t the right fix.
FAQs for East Dulwich
Do you take on hotel work around East Dulwich?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
I let a flat near East Dulwich station. Can you help?

What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.

Do you need fire rated sealant in East Dulwich?
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.
Most people get in touch when they notice something like this:
- Unsealed gaps around fire door frames
- Gaps around pipes and cables through fire-resisting walls
- Gaps where walls meet ceilings or slabs
- Cracked or shrunken fire-rated sealant
Schools such as Dog Kennel Hill School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any mould that needs treating
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
When you contact us, it’s useful to know:
- Whether it’s a home or a business
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that is easy
To get a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. You’ll have a clear quote before work begins.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Ask every contractor to reseal any fire stopping they disturb
- Get damaged fire seals looked at promptly
- Do not paint over fire sealant until it has cured
- Include hidden areas like risers in routine checks
Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record so you can show it was dealt with.
