Fire rated sealant in Englefield
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. We work on door frames, plasterboard & masonry and flats & HMOs, and the jobs we see most are door frames with gaps between frame and wall and open holes round services passing through fire walls.
If you have holiday lets, a converted barn used for business or a community building near Englefield, 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 email us.

Why deal with it now?
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own and needn’t wait for anything else. Older cottages and farmhouses around Englefield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

Can you tell me how many minutes the seal will last?

There can be a smell while the sealant cures. Opening a window helps.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It generally takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Englefield, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Different surfaces, different methods
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified, flat by flat if needed.
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.
Workplaces and buildings in Englefield
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Schools such as Englefield C.E. Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Letting a property close to Theale station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Signs you need fire rated sealant in Englefield
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
People normally contact us when they notice one of these:
- Gaps where walls meet ceilings or slabs
- Cracked or shrunken fire-rated sealant
- Open holes round services passing through fire walls
- Unsealed gaps around fire door frames
Community buildings like Church of St Mark are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Aftercare tips
Looking after new joints is easy:
- Allow for resealing whenever new services are run
- Do not paint over fire sealant until it has cured
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Ask every contractor to reseal any fire stopping they disturb
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
