Fire rated sealant in Todd's Green, done properly
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it. We’re often asked to deal with new service routes left unsealed after building work and fire seals that have cracked with movement, across service penetrations, plasterboard & masonry and linear gaps.
Work in a small place like Todd's Green is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Fire rated sealant in Todd's 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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Todd's Green has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Rented homes near Stevenage station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. Schools such as The John Henry Newman School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Openings too large for sealant, which need batts, boards or another system
- Deciding what fire stopping a building needs
- Certifying a building or signing off its fire safety
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.
What we seal
- Plasterboard & masonry
- Flats & HMOs
- Door frames
- Pipe & cable gaps
- Linear gaps
- Service penetrations
Different surfaces, different methods
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist.
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.

What else we do in Todd's Green
Common problems we fix in Todd's Green
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.
The most common problems we see are:
- Gaps around pipes and cables through fire-resisting walls
- Door frames with gaps between frame and wall
- Damaged fire sealant left by other trades
- Fire seals that have cracked with movement
For buildings such as Church of St Mary the Virgin, service openings in its walls need the right fire-rated sealant, as in any building.

The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. In a small place like Todd's Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.

Related advice
Todd's Green: your questions answered
Do you cover smaller places like Todd's Green?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you take on hotel work around Todd's Green?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
Will we have a record of what was sealed?
Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but won’t perform as fire stopping. Use a product tested for that gap and service.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
