Fire rated sealant in Sleaford, done properly
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That detail is what we take care over. We are often asked to deal with standard silicone or caulk in a fire-stopping gap and old fire sealant that has split or come away, on door frames, linear gaps and flats & HMOs.
Work in a small place like Sleaford is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Big or small, it’s backed by our 12-month guarantee.

Leave it or put it right?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Sleaford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What we are called out for in Sleaford
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.
These are the problems we’re asked about most:
- Door frames with gaps between frame and wall
- Damaged fire sealant left by other trades
- Gaps filled with a product that isn’t fire-rated
- Open joints along the top of partitions
Rented homes near Bentley (Hampshire) station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Questions to ask before booking
- Whether they seal over old material or remove it
- What insurance they hold
- What happens if they find a problem under the old sealant
- Which colour the sealant will be
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Sleaford, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Getting ready for the visit
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Make resealing part of every contractor’s brief
- Don’t paint over fire sealant until it has cured
- Never patch a fire seal with standard sealant
- Flag any open gap you spot round a pipe or cable
Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
Commercial buildings in Sleaford
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 are given, installing the product to its tested details.
For site and facilities teams at buildings such as Mill Chase Academy, service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Church of All Saints, service openings in its walls need the right fire-rated sealant, as in any building.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Different surfaces, different methods
Plasterboard walls
We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.
Door frames
Frame gaps are normally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size.
