Commercial Sealant in Petersham
Our applicators work in Petersham on sealant work for offices, hotels, washrooms and commercial buildings. Old sealant removed completely, joints prepared properly.

- Mouldy washroom sealant that staff and guests notice

DIY sealant or a professional job?
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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
How we handle commercial sealant in Petersham
Guest bathrooms are cleaned every day and used by different people every night, so sealant wears out faster than it would at home. We work through rooms in batches, keeping most rooms available. Typical jobs include sealant failing again soon after quick repairs and black, stained silicone in guest bathrooms, across retail & leisure sites, welfare facilities and rental portfolios.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Where a building in Petersham needs to stay open, work can be planned outside normal hours.
A 12-month guarantee comes as standard.

Questions from Petersham
I let a flat near St Margarets (London) station. Can you help?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Is parking an issue for commercial sealant in Petersham?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
How long does the job take?
Most jobs take a few hours for a single washroom, longer for a whole building, including preparation and clearing up. We will confirm how long when we quote.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What happens if it’s left?
Sealing over the old bead can seem the fastest option, but silicone does not bond to silicone, so it lifts. One proper reseal beats several quick ones. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Petersham, the repair is bigger than a sealant job.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Keeping the joints in good condition
So the new joints stay in good condition:
- Keep extractor fans working and serviced
- Ask cleaners to go gently on the silicone
- Plan resealing around quiet periods
- Check the joints during routine room inspections
Each room is handed back with its cure time, usually around 24 hours. Make sure housekeeping or cleaning staff know it so the new sealant is not wetted or scrubbed too soon.
It’s easier to plan a programme than to react to failures. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.
Commercial sealant around Petersham
London’s water is hard, which leaves limescale on sealant, grout and taps. There are hotels and other places to stay in and around Petersham. Hotel work can be planned room by room, with out-of-hours working where needed.
If you look after a building such as The Russell Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
