Fire rated sealant around Borehamwood
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’re given, installing the product to its tested details.
For site and facilities teams at buildings such as St Teresa Catholic Primary School, fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Elstree & Borehamwood station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

How we handle fire rated sealant in Borehamwood
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. We work on door frames, linear gaps and service penetrations, and the jobs we see most are seals cut through by electricians, plumbers or data installers and gaps where walls meet ceilings or slabs.
Shared washrooms take far more use than a home bathroom, and their sealant shows it, while fire-rated sealant has to be made good whenever new pipes or cables go through. In Borehamwood, timings are planned around the building.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

How we quote for fire rated sealant
Every job gets its own quote. These are the things that affect it:
- The number and length of the joints
- How easy the joints are to reach
- The type of sealant required
- How much old sealant there is and how hard it is to remove
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, and we will explain the quote if you ask.
Asking for a quote
To make quoting easier, let us know:
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- How we’d reach the joints
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.
Borehamwood: your questions answered
Can you help a landlord with a rental near Elstree & Borehamwood station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Is Borehamwood in your area for fire rated sealant?
Yes, Borehamwood is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Common problems we fix in Borehamwood
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
The problems people normally mention when they call include:
- Fire seals that have cracked with movement
- Ordinary sealant used where a fire-rated product was needed
- New service routes left unsealed after building work
- Gaps where walls meet ceilings or slabs
If you look after a church, hall or community building such as All Saints church, service openings in its walls need the right fire-rated sealant, as in any building.

Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. In a family home in Borehamwood, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Left alone, that means rot, damp and a bigger repair.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
Why us?
- 20+ years of sealant experience

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Tell trades working in the building that fire seals must be put back
- Allow for resealing whenever new services are run
- Take photos of fire stopping before ceilings or boxing go back
- Flag any open gap you spot round a pipe or cable
Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so you can show it was dealt with.
Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Deciding what fire stopping a building needs
- Construction that does not provide fire resistance on its own
- Sign-off of the building, which sits with building control or your assessor
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a job in Borehamwood, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
