Work for landlords, hotels and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
What affects the quote in Sandford-on-Thames
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Whether the work is at height
- How many rooms, windows or areas are involved
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What we need to know
When you contact us, these details help:
- Photos by email, if that’s easy
- Where the job is, and your postcode
- How we’d reach the joints
- Any previous sealing or DIY work

Commercial sealant in Sandford-on-Thames: local notes
Sandford-on-Thames has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Community buildings like Church of St Andrew are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. Rented homes near Radley station change hands often, and we can quote for one property or a whole portfolio of rentals.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep strong chemicals and scourers off the joints
- Log resealing so you know what’s due
- Schedule work around occupancy
- Get split or lifting joints looked at early
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.
Mould in shared washrooms gets noticed and talked about. The longer it’s left, the deeper it grows into the silicone, so the fix is replacement.
How it works
The work is kept neat and contained to the area we’re working on. The job usually takes a few hours for a single washroom, longer for a whole building, and we explain the cure time before we leave. Somewhere as small as Sandford-on-Thames, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.
Preparing for the visit
- Clear items away from the joints we’re working on
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

Your questions about commercial sealant in Sandford-on-Thames
Do you take on hotel work around Sandford-on-Thames?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Will you come out to Sandford-on-Thames?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you reseal bathrooms across several rental properties?
Yes. Between tenancies is a good time to reseal bathrooms and kitchens, and we can quote for several addresses at once.
Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
When to call us in Sandford-on-Thames
Shower trays and baths in busy buildings move more: different weights, constant use and daily cleaning all work at the joint. A tray that isn’t fully supported soon tears its seal.
Any of these means the joints need attention:
- Shower leaks reaching the floor below
- Sealant failing again soon after quick repairs
- Mouldy bathrooms flagged at a tenancy check
- Worktop sealant that has shrunk and stained
Managing a site like John Henry Newman Academy? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Surface by surface
Retail & leisure sites
Retail and leisure sites have washrooms, kitchens and changing areas with sealant to maintain. Work can be arranged outside opening hours where that is possible.
Welfare facilities
Busy staff showers wear sealant out quickly. Anti-fungal sanitary silicone is used throughout.
Why deal with it now?
Sealant is easy to forget until an audit or inspection is due. Planning the work ahead means rooms are finished and cured in time. Around Sandford-on-Thames, 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 generally makes better use of the time than several visits. We will give you a clear price for the lot.
