How the job changes 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
Before a health and safety visit or audit, tired sealant is easy to sort. Tell us your deadline and we will schedule around it, cure time included.
Commercial sealant in Deadwater: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For buildings such as St Mark's Sacred Church, halls and community kitchens see heavy use, and their sealant shows it. Managing a site like Mill Chase Academy? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Water coming from plumbing rather than sealant
- Assessing what fire stopping a building needs
- Extraction that isn’t working, which needs an electrician or ventilation contractor
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.

Signs you need commercial sealant in Deadwater
Shower trays and baths in busy buildings move more: different weights, constant use and daily cleaning. A tray that is not fully supported soon tears its seal.
Most people get in touch when they notice one of these:
- Mouldy bathrooms flagged at a tenancy check
- Mouldy washroom sealant that staff and guests notice
- Silicone laid over old silicone by a previous contractor
- Joints that need doing before an inspection or audit
For landlords with property near Liphook station, we can quote for one property or a whole portfolio of rentals.
What to look for in a quote
- How long the guarantee is
- What product goes in the joint
- What the cure time is
- How the joint is cleaned and prepared

For landlords and businesses
Housing providers, facilities teams and property managers book us too in Deadwater and across Hampshire. We can quote a run of properties together.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Your questions about commercial sealant in Deadwater
Do you cover Deadwater for commercial sealant?
Yes. Our work covers London and the South East, and Deadwater is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Is Deadwater within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
When can guests or staff use the shower again?
Around 24 hours is typical for sanitary silicone. Housekeeping get the cure time for each room.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you work outside opening hours?
Often, yes. Let us know when the building is quietest, and we will see what can be arranged.
What affects the quote in Deadwater
Call for a quick quote. What matters most is:
- The number of rooms or windows
- The old material and how stubborn it is
- How easy the joints are to reach
- The product the joint needs
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- Whether it has been sealed before
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
We don’t publish a price list. Instead, we send you a clear quote for your job. To get started, call 0345 464 0079 or drop us an email.
What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a morning for a small washroom, and a planned programme for bigger sites, depending on the amount of work. Parking around Deadwater is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- 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
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
