Commercial & hotel sealant in Coldharbour, Greater London
Sealant work for offices, hotels, washrooms and commercial buildings for householders, landlords and businesses in Coldharbour. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Mouldy bathrooms flagged at a tenancy check
- Washrooms that need sorting before an inspection
- Worktop sealant that has shrunk and stained
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Give housekeeping the cure time for every room
- Keep strong chemicals and scourers off the joints
- Report broken fans quickly
- Log resealing so you know what’s due
Each room is handed back with its cure time, normally around 24 hours. Make sure housekeeping or cleaning staff know it so the new sealant isn’t wetted or scrubbed too soon.
Signs to look for: mould, splits, peeling corners or water marks downstairs. When you see them, it’s time to plan a reseal.
How we handle commercial sealant in Coldharbour
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, applied by ARBOMaster approved applicators. We work on hotel bathrooms, rental portfolios and student & care accommodation, and people most often call us about shower leaks reaching the floor below and rental bathrooms that need resealing between tenants.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Coldharbour cannot close.
All of our work is guaranteed for twelve months, in Coldharbour and everywhere else we cover.

How we quote for commercial sealant
You will get a clear quote before work begins. It takes into account:
- The number of rooms or windows
- The product the joint needs
- Whether the work is at height
- Working hours on commercial sites
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Asking for a quote
What to tell us when you ask for a quote:
- Roughly how big the job is
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, call 0345 464 0079 or send us an email.
Your questions about commercial sealant in Coldharbour
Is parking an issue for commercial sealant in Coldharbour?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you take on hotel work around Coldharbour?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
How do I get a quote for commercial sealant in Coldharbour?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or drop us an email with a short description of the job.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
How long does the job take?
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.

Honest limits

- A broken extractor fan behind the mould problem
- Fire risk assessments or certification

- Welfare facilities
What the job involves on each surface
Welfare facilities
Shower rooms in welfare blocks get heavy use and need sound joints. We reseal with anti-fungal sanitary silicone, including accessible wet rooms.
Office washrooms & kitchens
Long vanity tops have joints that hold water and grime. We renew it in one tidy, continuous bead.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

For buildings such as All Saints Church, halls and community kitchens see heavy use, and their sealant shows it.
