Fire Rated Sealant in Shorthampton

Fire rated sealant in Shorthampton, done properly
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on linear gaps, door frames and service penetrations, and common reasons people get in touch are damaged fire sealant left by other trades and linear gaps at the head of walls.
If you have holiday lets, a converted barn used for business or a community building near Shorthampton, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Big or small, it’s backed by our one-year guarantee in Shorthampton and across Oxfordshire.

Surface by surface
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length so there are no open sections left.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for the gap we’re sealing.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Include hidden areas like risers in routine checks
- Get damaged fire seals looked at promptly
- Ask every contractor to reseal any fire stopping they disturb
- Never patch a fire seal with standard sealant
Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Why act early in Shorthampton
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Around Shorthampton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Fire rated sealant in Shorthampton: local notes
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
For buildings such as Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Charlbury station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
