Commercial sealant around Gustard Wood
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you look after a building such as St Helen's Church of England Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Community buildings like St Peter are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.

People usually contact us after spotting one of these:
- Tired sealant ahead of a health and safety audit
- Leaks from showers into rooms or ceilings below
- Leaking joints in shower rooms and changing areas
- Sealant failing again soon after quick repairs

Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Extraction that isn’t working, which needs an electrician or ventilation contractor
- Cracked trays or baths rather than failed joints
- Water damage behind the tiles that needs a tiler or builder
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Add sealant to your planned maintenance checks
- Check extract fans are actually running
- Book larger programmes for quieter times of year
- Keep strong chemicals and scourers off the joints
Add sealant checks to your planned maintenance. Checking joints alongside other room checks catches failures before they leak.
Planned resealing is easier to manage than emergency repairs. We can fit the work around bookings, shifts and opening hours, instead of rooms closing without warning.
How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job usually takes anything from a few hours to several days, depending on the number of rooms. In a small place like Gustard Wood, access is generally the main thing to plan. 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.
- Tell us what paperwork your site needs, and we confirm what we can supply before we start.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

FAQs for Gustard Wood
Do you cover smaller places like Gustard Wood?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Harpenden station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Will there be a smell?
Some sealants have a smell while they cure. Opening a window helps.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Is commercial work guaranteed?
Yes. We give a 12-month guarantee on every job and are fully insured.
How much does commercial sealant cost in Gustard Wood?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Can you reseal hotel rooms while we stay open?
Yes. We work through rooms in batches, so only a few are out of use at once. Housekeeping are told when each room can be let again.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Landlords and letting agents in Gustard Wood can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
