How we handle fire rated sealant in Forest Side
We often work from an action list drawn up by a fire risk assessor on buildings across Forest Side. If you share the list, we can quote for the gaps that need fire-rated sealant. If you are dealing with open joints along the top of partitions and gaps filled with a product that isn’t fire-rated, we can put it right, whatever the surface.
For holiday lets, converted business premises or a community building near Forest Side, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Your job is guaranteed for a year, as with all our work.

Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Can I use normal mastic around a pipe through a fire wall?
No. It looks sealed but won’t perform as fire stopping. A tested fire-rated product is needed and we can apply it for you.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Surface by surface
Flats and HMOs
Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and record where they are.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What happens on the day
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a small place like Forest Side, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- 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.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can

Related advice
Do you need fire rated sealant in Forest Side?
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.
If you can see any of these, it’s time to have the joints looked at:
- Standard silicone or caulk in a fire-stopping gap
- Gaps left after a refit or conversion
- Gaps flagged on a fire risk assessment
- Seals cut through by electricians, plumbers or data installers
Schools such as Carisbrooke College are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
What to look for in a quote
- What the cure time is
- How hidden problems are handled
- What preparation is included
- Which sealant they’ll use, and why
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep the record of products and locations with your fire safety documents
- Look in service cupboards and ceiling voids from time to time
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Plan fire stopping into any work that goes through walls or floors
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which we used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
