For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Fire rated sealant for homes and businesses in The Folly
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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. We work on door frames, flats & HMOs and pipe & cable gaps, and the jobs we see most are open gaps behind door architraves and open joints along the top of partitions.
Work in a small place like The Folly is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
Whatever the size of the job, it’s backed by our one-year guarantee in The Folly and across Hertfordshire.

The process
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like The Folly, access is usually 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.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Flag any open gap you spot round a pipe or cable
- Don’t paint over fire sealant until it has cured
- Make resealing part of every contractor’s brief
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
What affects the cost of fire rated sealant
We quote each job individually. This is what makes a difference:
- How much there is to do
- Working hours on commercial sites
- Whether the work is at height
- The product the joint needs
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
To help us quote quickly, please include:
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
To get a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before we start.
The Folly questions
Will you come out to The Folly?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Harpenden station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
What does fire rated sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Can you work in occupied buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, large or small.
Why deal with it now?
Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We will say so if a gap needs something other than sealant. Where a wall is exposed, as many are in small places like The Folly, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- Approved under the ARBOMaster scheme
- Tidy, careful work
- A 12-month guarantee on all work
- We’re fully insured

Fire rated sealant in The Folly: 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a church, hall or community building such as St Helen's Church, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as St Helen's Church of England Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Signs you need fire rated sealant in The Folly
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
If you can see any of these, it’s time to have the joints looked at:
- Gaps around pipes and cables through fire-resisting walls
- Open gaps behind door architraves
- Sealant items on a fire risk assessment action list
- New service routes left unsealed after building work
Letting a property close to Harpenden station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Honest limits
New sealant cannot fix everything, and we will tell you before work begins. It won’t solve:
- A wall that is not a fire-resisting element to begin with
- Deciding what fire stopping a building needs
- Big openings where sealant alone isn’t the tested solution
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.
