Fire rated sealant for homes and businesses in Watford Heath
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. Common call-outs are for door frames with gaps between frame and wall and joints picked up in a fire-stopping survey, across pipe & cable gaps, linear gaps and flats & HMOs.
In a smaller place like Watford Heath, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. The work is the same as in a big building, just on a smaller scale.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Photograph sealed gaps before they’re covered up
- Ask which product was used before you paint
- Never patch a fire seal with standard sealant
- Include fire stopping when you schedule refits
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.
What the job involves on each surface
Service penetrations
New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before the sealant goes in.
Leave it or put it right?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Homes in smaller places like Watford Heath can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

What happens on the day
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. In a smaller place like Watford Heath, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints

What else we do in Watford Heath
What sealant work cannot fix
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Deciding what fire stopping a building needs
- Problems with the door itself rather than the gap around the frame
- Large holes that need a different fire-stopping system
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
Where we work in Watford Heath
- Flats & HMOs
- Linear gaps
- Service penetrations
- Plasterboard & masonry
- Pipe & cable gaps
- Door frames
What we’re called out for in Watford Heath
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave does not always get resealed.
Keep an eye out for these signs:
- Fire stopping disturbed by later work
- Cracked or shrunken fire-rated sealant
- Gaps around pipes and cables through fire-resisting walls
- Ordinary sealant used where a fire-rated product was needed
If you look after a church, hall or community building such as Church of St Matthew, gaps around pipes and cables are worth checking after any building work there.
