Woolmer Fire Rated Sealant
We cover Woolmer for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Old fire sealant that has split or come away
- Joints picked up in a fire-stopping survey
- Gaps left after a refit or conversion
About our fire rated sealant in Woolmer
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. We are often asked to deal with standard silicone or caulk in a fire-stopping gap and seals cut through by electricians, plumbers or data installers, on flats & HMOs, pipe & cable gaps and plasterboard & masonry.
For a small place like Woolmer, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What we’re called out for in Woolmer
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
Signs it’s time to call us include:
- Linear gaps at the head of walls
- Old fire sealant that has split or come away
- New service routes left unsealed after building work
- Joints picked up in a fire-stopping survey
Rented homes near Liss station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Woolmer, 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.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used.
Getting ready for the visit
- Mention any tricky access
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

How the job changes by surface
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the sealant bonds.
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail, and we will tell you.
What affects the quote in Woolmer
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The size of the job
- Any working-time requirements on site
Combining jobs into one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.
Asking for a quote
Before you ask for a quote, have a think about:
- The rough size of the job
- Whether it has been sealed before
- Where the property is
- A few photos by email, if you can
Getting a quote is simple: tell us what needs doing and where. A few pictures by email make the job easier to understand, and we’ll take it from there.
Woolmer questions
Will you come out to Woolmer?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Liss station?
Yes. We work for letting agents and landlords as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Can you fill the gap behind a fire door frame?
Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you tell me how many minutes the seal will last?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and list the locations and products for you.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Store the list of sealed gaps with your building paperwork
- Don’t paint over fire sealant until it has cured
- Get damaged fire seals looked at promptly
- Make resealing part of every contractor’s brief
Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the list grows.
Why it’s worth doing now in Woolmer
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing once someone inspects it. Where a wall is exposed, as many are in small places like Woolmer, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Workplaces and buildings in Woolmer
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.
Schools such as St Matthew's Church of England Aided Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Community buildings like St Matthew's Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
