Fenn Street Fire Rated Sealant
Our applicators work in Fenn Street on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly.
- Gaps left after a refit or conversion
- Door frames with gaps between frame and wall
- Gaps filled with a product that isn’t fire-rated
Why act early in Fenn Street
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. Around Fenn Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Fire rated sealant in Fenn Street, done properly
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. We work on linear gaps, plasterboard & masonry and service penetrations, and people most often call us about unsealed gaps where pipes and cables go through a wall and damaged fire sealant left by other trades.
If you have holiday lets, a converted barn used for business or a community building near Fenn Street, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Your job is guaranteed for a year, as with all our work.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Plan fire stopping into any work that goes through walls or floors
- Flag any open gap you spot round a pipe or cable
- Check whether a sealant can be painted before decorating over it
- File the fire-stopping record where your assessor can find it
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the list grows.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Doors that are not fire doors in the first place
- Sign-off of the building, which sits with building control or your assessor
- Construction that doesn’t provide fire resistance on its own
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.

DIY sealant or a professional job?
If you’re 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 doesn’t work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on how many gaps there are. In a small place like Fenn Street, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Advice
Signs you need fire rated sealant in Fenn Street
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried.
Signs it’s time to call us include:
- Open gaps behind door architraves
- Gaps flagged on a fire risk assessment
- Gaps filled with a product that isn’t fire-rated
- Seals cut through by electricians, plumbers or data installers
If you let a flat or house near Gillingham (Kent) station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Different surfaces, different methods
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the sealant bonds.
Your questions about fire rated sealant in Fenn Street
Do you cover smaller places like Fenn Street?
Yes, Fenn Street is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Are you insured?
Yes. We’re fully insured.
What does intumescent mean?
Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can ordinary silicone be used in a fire-stopping gap?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.
Do you work in flats, HMOs and commercial buildings?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we will plan around it.
How do I get a quote for fire rated sealant in Fenn Street?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Workplaces and buildings in Fenn Street
If you run a hotel, guest house or holiday let in a coastal place like Fenn Street, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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.
Community buildings like Church of St Mary are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you look after a building such as High Halstow Primary Academy, gaps opened by contractors for new cabling are a common finding in schools and offices.
