What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It usually takes a morning for a small washroom, and a planned programme for bigger sites. For a village or hamlet like Upper Farringdon, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- We let your team know the cure time for every area.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts

What happens if it’s left?
Patching the worst rooms as complaints come in is hard to manage. A planned programme works through every room, keeping disruption down and costs clear. Around Upper Farringdon, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.

Upper Farringdon: your questions answered
Will you come out to Upper Farringdon?
Yes. Upper Farringdon is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Alton station. Can you help?
Yes, rental work is part of what we do. You can phone 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.
Where is Mr Mastic based?
We work from Crawley. We cover Upper Farringdon and the rest of Hampshire.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
How long do rooms need to be out of use?
Plan for around 24 hours, or the cure time we give for that area. A room-by-room programme keeps only a few rooms out at once.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Can you work outside opening hours?
Out-of-hours work and early starts can be arranged. Tell us what you need when you ask for a quote.
Do you provide RAMS?
We’re fully insured, and we will go through your site’s requirements with you. Send over your requirements and we’ll confirm what we can provide.
What sealant work can’t fix
We will not take on work that won’t last, so these are the limits:
- Damaged sanitaryware that needs replacing
- Failed tanking or loose tiles behind the sealant
- Water coming from plumbing rather than sealant
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.

What the job involves on each surface
Welfare facilities
Failed sealant in welfare areas is a simple fix before an audit. Tell us your deadline and we will schedule around it, cure time included.
Retail & leisure sites
Customer toilets reflect on the business, and fresh sealant makes them look well kept.
Landlords, agents and businesses in Upper Farringdon
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Landlords and letting agents in Upper Farringdon can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Get split or lifting joints looked at early
- Log resealing so you know what’s due
- Encourage users to squeegee shower walls
- Pass on the cure time to whoever cleans the rooms
Make it easy for staff to flag a failing joint. Catching one split early can save a leak later.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.
Commercial sealant in Upper Farringdon: local notes
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.
For buildings such as Church of All Saints, halls and community kitchens see heavy use, and their sealant shows it. If you let a flat or house near Alton station, several rental properties can be resealed on one programme.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
