What the job involves on each surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for the gap we are sealing.
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 so the sealant bonds.
About our fire rated sealant in Stonebridge
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. We work on pipe & cable gaps, flats & HMOs and service penetrations, and common reasons people get in touch are damaged fire sealant left by other trades and holes left by a change of layout.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Stonebridge, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
All our work is covered by our one-year guarantee.

Fire rated sealant in Stonebridge: 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. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
For buildings such as Saint Michael and All Angels, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like The Stonebridge School? Then fire-stopping around service openings should be restored whenever new services go in.

Do you need fire rated sealant in Stonebridge?
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
Any of these means the joints need attention:
- Gaps left after a refit or conversion
- Gaps around pipes and cables through fire-resisting walls
- Cracked or shrunken fire-rated sealant
- Standard silicone or caulk in a fire-stopping gap
If you let a flat or house near Harlesden station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How the visit works
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before we start. The work normally takes from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Stonebridge. It helps if you can point us to a visitor permit or a bay close to the door.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

Advice
How we quote for fire rated sealant
Your quote is based on your job. We look at:
- Any working-time requirements on site
- Access and height
- The number and length of the joints
- Mould in or behind the old joints
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
What we need to know
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- The address or postcode of the job
- The type of property
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or drop us an email.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Ask every contractor to reseal any fire stopping they disturb
- Include fire stopping when you schedule refits
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Report cracked or damaged seals as soon as you notice them
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Common questions in Stonebridge
Can you help a landlord with a rental near Harlesden station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Can parking be tricky for a visit in Stonebridge?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Will we have a record of what was sealed?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How much does fire rated sealant cost in Stonebridge?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
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. We apply the specified product to the manufacturer’s details and list the locations and products for you.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
