DIY versus a professional 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 doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Commercial sealant for homes and businesses in Osterley
For a rental portfolio, resealing between tenants keeps bathrooms and kitchens presentable. We can quote for several properties at once. If you are dealing with mouldy bathrooms flagged at a tenancy check and washrooms that need sorting before an inspection, we can help, on welfare facilities, hotel bathrooms and student & care accommodation alike.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Osterley, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Commercial sealant in Osterley: local notes
London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
Managing a site like Isleworth and Syon School for Boys? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Letting a property close to Isleworth station? Then sealant work can be quoted for a single flat or a whole portfolio. Community buildings like St Mary's Church are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Note the date each area was done
- Use mild cleaners on sealant, not bleach or abrasives
- Plan resealing around quiet periods
- Don’t leave a failed joint until the next refurbishment
Strong chemicals and scourers wear silicone out faster. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.
Black sealant in a staff washroom or guest bathroom draws complaints. The longer it’s left, the deeper it grows into the silicone, and only replacement fixes it.
What happens on the day
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes as long as the scope needs, from one welfare room to a full building in most cases. For a job in Osterley, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
Before we arrive
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks

Advice
Leave it or put it right?
Sealant work is quick by the room: the job takes anything from a few hours to several days, depending on the number of rooms. Each area is then left to cure for the time we give you, so the programme is planned around cure times. 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 Osterley, the repair is bigger than the sealant job would have been.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Osterley questions
Do you work for landlords with property near Isleworth station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Do you take on hotel work around Osterley?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Which products 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.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
Do you come to Osterley?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
How long do rooms need to be out of use?
Usually after around 24 hours. Each room is handed back with the cure time for the product used.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
What the job involves on each surface
Hotel bathrooms
We work through hotel rooms in agreed batches, keeping most of the hotel open. Each room is handed back with its cure time for housekeeping.
Student & care accommodation
Vacant rooms make resealing quick and simple, but occupied rooms can be planned in as well.
