Hook questions
Can you help a landlord with a rental near Chessington North station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Is Hook in your area for commercial sealant?
Yes. We work across London and the South East, and Hook is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Can you work around guests in a hotel?
Yes. Rooms are done a few at a time, so only a few are out of use at once. Housekeeping are told when each room can be let again.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What sealant work can’t fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- A broken extractor fan behind the mould problem
- Fire risk assessments or certification
- Water coming from plumbing rather than sealant
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.

Quotes for commercial sealant in Hook
The quote reflects the job in front of us. We take into account:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Any working-time requirements on site
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
What to tell us when you ask for a quote:
- Where the property is
- Any access issues, like height or stairs
- Photos by email, if that is easy
- If someone has resealed it before
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand.
What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a morning for a small washroom, and a planned programme for bigger sites. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
- Joints are cleaned, treated for mould and dried.
- New sealant suited to each area is applied and tooled.
- Each room is checked and handed back with its cure time.
Preparing for the visit
- Clear items away from the joints we are working on
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules

Why it’s worth doing now in Hook
Refitting a washroom is a big, disruptive project. If the fittings are in good order, new sealant is often all it needs. We’ll tell you if we find anything that needs another trade. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Hook, the repair is bigger than a sealant job.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Hook is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Chessington North station, we can quote for one property or a whole portfolio of rentals.

Common problems we fix in Hook
Internal washrooms and en suites without a window rely entirely on extraction, so if the fan is weak, steam lingers and the sealant stays damp. That’s when black mould sets into the bead.
Keep an eye out for any of the following:
- Washroom sealant that looks dirty however often it’s cleaned
- Sealant failing again soon after quick repairs
- Split sealant where wet room floors meet walls
- Large numbers of bathrooms needing the same work
Community buildings like St Paul's are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.
