Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Commercial mastic work in Winchmore Hill
How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead. We work on washrooms and tea points, window and door perimeters and external facade joints, and the failures we’re asked to look at most are movement joints packed with grit and debris and leaks that seem to come through a sealant line. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Winchmore Hill, that means joint design, primers and backing rod as standard.
In an occupied building in Winchmore Hill, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.
In and around smaller places such as Winchmore Hill, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Faulty windows rather than failed perimeter sealant
- Structural cracks or movement the joints weren’t designed for
- Suspect materials that need testing and specialist removal

Common questions from Winchmore Hill clients
What documents will you need to give us for a job in Winchmore Hill?
We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Is Winchmore Hill too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
How do you keep disruption to occupiers down?
That comes down to planning: areas are phased, access windows agreed and enough washrooms or entrances left in use. Tell us what has to stay open and we’ll plan the job around it.
Do you work for facilities managers and managing agents?
Yes. We quote, schedule and report back in the way that suits your process.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
How is commercial sealant work priced?
Send what you have, even a few photographs and rough lengths. Questions or a site visit follow where needed, then a fixed quote.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What happens if it’s left?
Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement. Converted and older buildings near places like Winchmore Hill tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
Why us?

Our process
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. If others near Winchmore Hill need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
Getting the site ready
- Arrange parking or a loading space
- Move anything stored against the joints
- Warn occupants and staff about the work
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Related advice
After the work
For the best life from the joints:
- Have extract fans checked so wet areas dry out
- Deal with small splits before they become leaks
- Make sure contractors see the asbestos survey before cutting out old mastic
- Add sealant to the planned maintenance inspection list
Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.
Sealant rarely fails all at once across a building. A few splits this year usually mean more next year. We can assess the lot and suggest what to do now and later.

Different surfaces, different methods
Commercial kitchens and tea points
In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. Proper degreasing comes before any new sealant, and a hygienic or food-safe sealant is used where food contact is possible.
Washrooms and toilets
Mould that has grown into washroom sealant can’t normally be cleaned out. The lasting answer is removal, preparation and a new sanitary bead, room by room if that suits the building.
