Washrooms, bathrooms and kitchens in Bicester need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.

How we handle commercial sealant in Bicester
Mr Mastic brings more than 20 years’ experience to commercial sites, and we’re fully insured and ARBOMaster approved. Tell us what paperwork your site needs, such as RAMS or insurance details, and we will confirm what we can supply with the quote. If you’re dealing with shower leaks reaching the floor below and large numbers of bathrooms needing the same work, we can help.
Shared washrooms take far more use than a home bathroom, and their sealant shows it, while fire-rated sealant has to be made good whenever new pipes or cables go through. In Bicester, timings are planned around the building.
All our work is covered by a 12-month guarantee.

For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
For anyone letting property in or around Bicester, several properties can go on one quote. Just tell us the addresses and what each one needs.
Different surfaces, different methods
Rental portfolios
Between tenancies is a good time to reseal, so the next tenant moves in to clean, sound joints.
Welfare facilities
Shower rooms in welfare blocks get heavy use and need sound joints. We reseal with anti-fungal sanitary silicone.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours per area, with larger sites planned over several visits, depending on the size of the job. For a job in Bicester, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- The first visit is a look round the site to agree the scope.
- We agree when we will work, with early or out-of-hours slots where they can be arranged.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about any water getting in
- Mention any parking rules near the property

Advice
What sealant work cannot fix
Before booking, it’s worth knowing the limits too:
- Extraction that is not working, which needs an electrician or ventilation contractor
- Failed tanking or loose tiles behind the sealant
- Damaged sanitaryware that needs replacing
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

What else we do in Bicester
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Pass on the cure time to whoever cleans the rooms
- Leave squeegees in busy showers
- Act on lifting sealant before it leaks
- Check the joints during routine room inspections
Include sealant in routine room inspections. Checking joints alongside other room checks catches failures before they leak.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.
Questions from Bicester
Is Bicester in your area for commercial sealant?
Yes. We work across London and the South East, and Bicester is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
What guarantee comes with commercial sealant in Bicester?
All our work, in Bicester and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can you reseal bathrooms across several rental properties?
Yes. Tell us the addresses and the rooms, and we will send you a clear quote.
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. Brands we use include Arbo and Everbuild.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Can you work around guests in a hotel?
Usually, yes. We agree the room order and times with your managers, and you’ll know when each room can be used.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Commercial sealant around Bicester
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Managing a site like Brookside Primary School? Then busy washrooms and kitchens can be resealed in phases so they stay open. Community buildings like Church of St Edburg are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.
