Commercial sealant in Denmead, done properly
For a rental portfolio, resealing between tenants keeps bathrooms and kitchens presentable. Several addresses can go on one quote. If you have washroom sealant that looks dirty however often it’s cleaned and split sealant where wet room floors meet walls, we can put it right, whatever the surface.
Commercial work around a smaller place like Denmead normally means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.
All our work comes with our one-year guarantee.

Do you need commercial sealant in Denmead?
Staff kitchens and food areas see constant splashing and wiping, and grease and cleaning sprays break down sealant. Worktop and sink joints are often the first to go.
Common reasons people contact us are:
- Too many rooms to reseal without closing the building
- Silicone laid over old silicone by a previous contractor
- Black, stained silicone in guest bathrooms
- Rental bathrooms that need resealing between tenants
For site and facilities teams at buildings such as Denmead Junior School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

What affects the cost of commercial sealant
Call for a quick quote. The main things that affect it are:
- How many areas need sealing
- The product the joint needs
- Whether the work is at height
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What we need to know
You do not need to know the technical terms. Just tell us:
- Where the property is
- The type of property
- How we’d reach the joints
- If someone has resealed it before
For a quote, call 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.
Denmead questions
Do you cover smaller places like Denmead?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Cosham station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can you start early or work out of hours?
Often, yes. Tell us your opening hours and quiet times, and we will plan the work around them.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single washroom, longer for a whole building. In a smaller place like Denmead, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- 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.
- Each finished area is checked with you and given a cure time.
Before we arrive
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Tell us about any water getting in

What the job involves on each surface
Welfare facilities
Staff welfare areas are needed every shift. Work can be split into sections.
Student & care accommodation
Care homes need careful planning around residents, and staff are told when each bathroom can be used.
Why it’s worth doing now in Denmead
A leaking shower in a hotel room or flat above can damage the ceiling below. Then two rooms are out of action, not one. A reseal now avoids that. In a smaller place like Denmead, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
What you get with us
- Colour picked to suit the job
- Colour agreed with you before we start
- Homes, businesses and hotels

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
