Commercial sealant for homes and businesses in Whetstone
Staff facilities cannot be out of action for long. We can plan the work for early mornings or out of hours to keep disruption down. You’re told when each area can be used again. If you have silicone laid over old silicone by a previous contractor and worktop sealant that has shrunk and stained, we can help, whatever the surface.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Whetstone, and room-by-room programmes can be planned where needed.
Your job is guaranteed for a year, as with all our work.

- Split sealant where wet room floors meet walls
- Mouldy bathrooms flagged at a tenancy check
- Tired sealant ahead of a health and safety audit
As a London address, Whetstone can be tricky for parking: let us know about parking bays, permits or a driveway.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Why it’s worth doing now in Whetstone
A quick bead over the old sealant might get a room back in use today, but it won’t bond, and it lifts again soon. One proper reseal beats several quick ones. In a flat in Whetstone, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

- Arbo and Everbuild products
- Approved under the ARBOMaster scheme

Whetstone questions
Can you do commercial sealant in Whetstone?
Yes. Our work covers London and the South East, and Whetstone is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.
Can you help a landlord with a rental near Oakleigh Park station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
How soon can a room be used after resealing?
Most areas can be used after around 24 hours. We give a cure time for each area.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you take on large, multi-room jobs?
Yes. With more than 20 years’ experience and over 2,847 projects behind us, we plan big jobs so the building keeps running.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours per room, so whole buildings are phased. We’ll tell you when we quote.
What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single washroom, longer for a whole building. In Whetstone, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we visit and agree the scope, the sequence and the working hours.
- Room by room, we protect the area and remove all the old sealant.
- The joints are degreased, treated and left to dry.
- New sealant suited to each area is applied and tooled.
- Each room is checked and handed back with its cure time.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

Commercial buildings in Whetstone
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
Letting a property close to Oakleigh Park station? Then several rental properties can be resealed on one programme. If you look after a church, hall or community building such as Church of St John, any kitchen and washrooms need the same sealant care as any other building.
