Commercial sealant in Coldwaltham: local notes
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.
Rented homes near Pulborough station change hands often, and several rental properties can be resealed on one programme. If you look after a church, hall or community building such as The Parish Church of St Giles, any kitchen and washrooms need the same sealant care as any other building. Managing a site like St James' CofE Primary School? Then washroom and kitchen sealant can be programmed around term times or opening hours.

Coldwaltham questions
I let a flat near Pulborough station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Do you cover Coldwaltham for commercial sealant?
Yes. Our work covers London and the South East, and Coldwaltham is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Where are you based?
Mr Mastic is based in Crawley. We cover Coldwaltham and the rest of West Sussex, along with the rest of our area.
Can you work around guests in a hotel?
Yes. The order and timing are agreed with your team, and each room is handed back with a cure time.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Cracked trays or baths rather than failed joints
- Assessing what fire stopping a building needs
- Water damage behind the tiles that needs a tiler or builder
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
What we seal
- Office washrooms & kitchens
- Student & care accommodation
- Rental portfolios
- Welfare facilities
- Hotel bathrooms
- Retail & leisure sites
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Report broken fans quickly
- Plan resealing around quiet periods
- Use mild cleaners on sealant, not bleach or abrasives
- Don’t leave a failed joint until the next refurbishment
We give a cure time for every area we finish, normally around 24 hours. Make sure housekeeping or cleaning staff know it so the new sealant isn’t wetted or scrubbed too soon.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.
DIY versus a professional finish
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.
A careful DIYer can reseal a simple joint, 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.
Surface by surface
Office washrooms & kitchens
Office washrooms and tea points are used all day, so we can work early or out of hours where that can be arranged. Basins, urinals, worktops and sinks are all resealed.
Hotel bathrooms
Guest bathrooms are resealed room by room or in batches, so most rooms stay available. Each room is handed back with its cure time for housekeeping.
How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a single washroom, longer for a whole building, including the tidy-up. In a small place like Coldwaltham, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Each finished area is checked with you and given a cure time.
Before we arrive
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
