Fire rated sealant in Tonwell
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We work on service penetrations, plasterboard & masonry and linear gaps, and common reasons people get in touch are standard silicone or caulk in a fire-stopping gap and unsealed gaps where pipes and cables go through a wall.
In a village or hamlet like Tonwell, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

When to call us in Tonwell
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.
These are the problems we’re asked about most:
- Unsealed gaps around fire door frames
- Old fire sealant that has split or come away
- Gaps filled with a product that isn’t fire-rated
- Open joints along the top of partitions
Managing a site like Tonwell St Mary's Church of England Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.
What your quote should include
- How much experience the applicator has
- How the surfaces are prepared before sealing
- Which sealant they’ll use, and why
- What guarantee comes with the work

How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are, including the tidy-up. For a village or hamlet like Tonwell, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks

Advice
Looking after it afterwards
After the cure time, these simple habits help:
- Ask which product was used before you paint
- Store the list of sealed gaps with your building paperwork
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Ask every contractor to reseal any fire stopping they disturb
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Every job gets its own quote. This is what makes a difference:

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Different surfaces, different methods
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified, flat by flat if needed.
