Fire rated sealant in Haslar
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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. Typical jobs include door frames with gaps between frame and wall and fire seals that have cracked with movement, across service penetrations, linear gaps and plasterboard & masonry.
If you have holiday lets, a converted barn used for business or a community building near Haslar, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Do you need fire rated sealant in Haslar?
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
If you can see any of these, it’s time to have the joints looked at:
- Sealant items on a fire risk assessment action list
- Fire stopping disturbed by later work
- Open gaps behind door architraves
- Standard silicone or caulk in a fire-stopping gap
If you look after a building such as Haselworth Primary School, service openings in fire-resisting walls need checking after any refurbishment.
Questions to ask before you book
- Whether you can choose the colour
- How the joint is cleaned and prepared
- How hidden problems are handled
- The length of the guarantee

What sealant work can’t fix
New sealant cannot fix everything, and we will tell you before work begins. It won’t solve:
- Issuing a fire rating or certificate for a building
- Assessing a building’s fire safety
- Openings too large for sealant, which need batts, boards or another system
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- Door frames
- Plasterboard & masonry
- Linear gaps
- Service penetrations
- Flats & HMOs
- Pipe & cable gaps
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Plan fire stopping into any work that goes through walls or floors
- Don’t paint over fire sealant until it has cured
- Look in service cupboards and ceiling voids from time to time
- Report cracked or damaged seals as soon as you notice them
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Haslar, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

How the job changes by surface
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
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.

Fire rated sealant in Haslar: local notes
If you run a hotel, guest house or holiday let in a coastal place like Haslar, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you let a flat or house near Portsmouth Harbour station, any gap left by new services in shared walls should be closed with a fire-rated product. Community buildings like St Francis are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
