Why act early in Alfold Crossways
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In a small place like Alfold Crossways, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before work begins.

Fire rated sealant in Alfold Crossways
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. Common call-outs are for fire stopping disturbed by later work and open joints along the top of partitions, across flats & HMOs, pipe & cable gaps and door frames.
For a small place like Alfold Crossways, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
A one-year guarantee comes as standard.

When something else is needed
It helps to know what we cannot do too:
- A wall that isn’t a fire-resisting element to begin with
- Fire risk assessments, which need a qualified assessor
- Problems with the door itself rather than the gap around the frame
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

How to look after the new joints
After the cure time, these simple habits help:
- Plan fire stopping into any work that goes through walls or floors
- Look in service cupboards and ceiling voids from time to time
- Report cracked or damaged seals as soon as you notice them
- Store the list of sealed gaps with your building paperwork
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Different surfaces, different methods
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing.
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
What fire rated sealant looks like in Alfold Crossways
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.
For buildings such as Church of St Nicholas, gaps around pipes and cables are worth checking after any building work there.

How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Alfold Crossways, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start with the survey or action list, checking the size and surfaces of every gap.
- 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.
- We record the locations and products used for your records.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
