How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the number of rooms. Somewhere like Elvendon needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We walk the site with you and agree the rooms, the order and the hours.
- Every area is sheeted and the old silicone stripped out.
- The joints are degreased, treated and left to dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Rooms are checked and returned with a cure time so staff know when to use them.
Before we arrive
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Advice
When it is not the sealant
In fairness, some problems need a different trade:
- Water coming from plumbing rather than sealant
- Damaged sanitaryware that needs replacing
- A broken extractor fan behind the mould problem
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.
Surfaces we seal
- Welfare facilities
- Office washrooms & kitchens
- Retail & leisure sites
- Student & care accommodation
- Rental portfolios
- Hotel bathrooms
DIY versus a professional finish
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.
If you do try it yourself, take your time over the 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.

Common questions in Elvendon
Do you cover Elvendon for commercial sealant?
Yes. Our work covers London and the South East, and Elvendon is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Do you work for landlords with property near Goring & Streatley station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Can you work outside opening hours?
Early starts and out-of-hours work can be arranged. Tell us what you need when you ask for a quote.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
How long do rooms need to be out of use?
Follow the cure time we give you, which is normally around 24 hours. A room-by-room programme keeps only a few rooms out at once.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Does commercial work come with a guarantee?
Yes, with our 12-month guarantee. Regular gentle cleaning and working extraction help the sealant last.
Can the hotel stay open while you work?
Yes. We agree the room order and times with your managers, and each room is handed back with a cure time.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Tell cleaning staff when each room can be used
- Check the joints during routine room inspections
- Check extract fans are actually running
- Put a squeegee in each shower
Include sealant in routine room inspections. A quick look at each bathroom when rooms are checked spots problems early.
Rooms out of use cost a hotel or landlord money. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.
When to call us in Elvendon
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 is when black mould sets into the bead.
Most people get in touch when they notice something like this:
- Repeated reseals that don’t last
- Leaks from showers into rooms or ceilings below
- Washroom sealant that looks dirty however often it’s cleaned
- Rental bathrooms that need resealing between tenants
For landlords with property near Goring & Streatley station, we can quote for one property or a whole portfolio of rentals.
What your quote should include
- The length of the guarantee
- Whether VAT is included
- What product goes in the joint
- How the surfaces are prepared before sealing
Commercial buildings in Elvendon
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as The Oratory Preparatory School, washroom and kitchen sealant can be programmed around term times or opening hours.
