What affects the cost of fire rated sealant
Jobs vary more than people expect. What affects the quote:
- The old material and how stubborn it is
- Whether there’s mould to deal with
- The size of the job
- Working hours on commercial sites
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.
What we need to know
To make quoting easier, please include:
- The problem you’ve noticed
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Whether it has been sealed before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or drop us an email.
Fire rated sealant for homes and businesses in High Wych
We can work through a building room by room or floor by floor, with each location and product recorded. That record is useful for your files and for whoever looks at the building next. We work on pipe & cable gaps, service penetrations and linear gaps, and the jobs we see most are gaps left after a refit or conversion and ordinary sealant used where a fire-rated product was needed.
For a small place like High Wych, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What we are called out for in High Wych
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
Any of these means the joints need attention:
- Old fire sealant that has split or come away
- Unsealed gaps where pipes and cables go through a wall
- Open gaps behind door architraves
- Standard silicone or caulk in a fire-stopping gap
If you let a flat or house near Harlow Mill station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Before you book anyone
- What insurance they hold
- How the joint is cleaned and prepared
- Who turns up on the day
- Which sealant they’ll use, and why
What we can’t put right
We will always be straight with you, so here’s what sealant cannot fix:
- Fire risk assessments, which need a qualified assessor
- Walls or floors that weren’t built to resist fire
- Issuing a fire rating or certificate for a building
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Surfaces we seal
- Flats & HMOs
- Door frames
- Linear gaps
- Service penetrations
- Pipe & cable gaps
- Plasterboard & masonry
How the job changes by surface
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Door frames
Frame gaps are generally hidden behind the architrave. We seal any open gap to the product’s tested details.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. In a small place like High Wych, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

Advice
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Don’t paint over fire sealant until it has cured
- Look in service cupboards and ceiling voids from time to time
- Tell trades working in the building that fire seals must be put back
- Store the list of sealed gaps with your building paperwork
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the list grows.
Fire rated sealant in High Wych: local notes
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
If you look after a building such as High Wych Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like Parish Church of St James the Great are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

What’s the difference between intumescent and fire-rated sealant?
An intumescent sealant expands when it gets hot. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Can you tell me how many minutes the seal will last?
We do not certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and list the locations and products for you.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
