- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.

What else we do in Harrow Weald
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Plan resealing around quiet periods
- Include the silicone on your room checklists
- Don’t leave a failed joint until the next refurbishment
- Keep strong chemicals and scourers off the joints
Extract fans need to work. In internal bathrooms, a weak or broken fan lets moisture linger, and mould comes back faster without it.
It’s easier to plan a programme than to react to failures. We can fit the work around bookings, shifts and opening hours, rather than closed at short notice.
How the job changes by surface
Office washrooms & kitchens
Long vanity tops have joints that hold water and grime. It’s cut out, cleaned and resealed in one neat line.
Welfare facilities
Busy staff showers wear sealant out quickly. Anti-fungal sanitary silicone is used throughout, including accessible wet rooms.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Harrow Weald questions
Is parking an issue for commercial sealant in Harrow Weald?
Parking in Harrow Weald, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you cover Harrow Weald for commercial sealant?
Yes, Harrow Weald is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours for a single washroom, longer for a whole building. We’ll tell you when we quote.
What does commercial sealant cost?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

- Whether you can choose the colour
- What happens if they find a problem under the old sealant
Commercial sealant around Harrow Weald
London has hard water, so limescale builds up on sealant, grout and fittings, 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.
Harrow Weald is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a building such as Salvatorian Roman Catholic College, busy washrooms and kitchens can be resealed in phases so they stay open.

Why act early in Harrow Weald
Sealant is easy to forget until an audit or inspection is due. Booking it in good time leaves room for the cure time before the visit. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Harrow Weald, the repair is bigger than the sealant job would have been.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
