Fire rated sealant for homes and businesses in Greensted Green
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. If you are dealing with unsealed gaps around fire door frames and fire stopping disturbed by later work, we can put it right, on plasterboard & masonry, door frames and linear gaps alike.
For holiday lets, converted business premises or a community building near Greensted Green, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
All of our work is guaranteed for twelve months, in Greensted Green and everywhere else we cover.

Leave it or put it right?
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that doesn’t depend on other work. Older cottages and farmhouses around Greensted Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

What the job involves on each surface
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Greensted Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
