Cambridge Heath Commercial Sealant
Sealant work for offices, hotels, washrooms and commercial buildings for homeowners, landlords and businesses in Cambridge Heath. Fully insured, ARBOMaster approved and guaranteed for a year.
- Shower leaks reaching the floor below
- Washrooms that need sorting before an inspection
- Washroom sealant that looks dirty however often it’s cleaned
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Commercial sealant for homes and businesses in Cambridge Heath
Mr Mastic brings more than 20 years’ experience to commercial sites, and we are fully insured and ARBOMaster approved. Tell us what paperwork your site needs, such as RAMS or insurance details, and we will confirm what we can supply with the quote. If you are dealing with split sealant around staff kitchen worktops and sinks and leaks from showers into rooms or ceilings below, we can help, on welfare facilities, rental portfolios and student & care accommodation alike.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Cambridge Heath, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

Aftercare tips
Looking after new joints is easy:
- Get split or lifting joints looked at early
- Pass on the cure time to whoever cleans the rooms
- Schedule work around occupancy
- Log resealing so you know what’s due
Keep the extraction running and maintained. In internal bathrooms, a weak or broken fan lets moisture linger, and that’s what keeps mould away.
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.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Your questions about commercial sealant in Cambridge Heath
Is parking a problem for a job in Cambridge Heath?
Parking in Cambridge Heath, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for hotels and guest houses in Cambridge Heath?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Is there a guarantee?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
What does commercial sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before we start.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
What should I tell you?
A short description and the location. If we need more, we’ll ask.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Surface by surface
Office washrooms & kitchens
In staff kitchens, we degrease joints before resealing, using a food-safe sealant by sinks where it’s needed.
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’s possible.
The process
Our applicators work methodically: 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, and the area is left clean. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Cambridge Heath. It helps if you can point us to a visitor permit or a bay close to the door.
- First we visit and agree the scope, the sequence and the working hours.
- Each area is protected and the old sealant cut out completely.
- We clean the joints, treat any mould and let them dry.
- New sealant suited to each area is applied and tooled.
- Each room is checked and handed back with its cure time.
Before we arrive
- Mention any tricky access
- Mention any parking rules near the property
- Clear the area around the work
Ask for a quote
Asking for a quote is easy: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll take it from there.
Related advice
Commercial sealant in Cambridge Heath: local notes
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
Cambridge Heath is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For buildings such as St James-the-Less, its kitchen and washroom sealant needs looking after like anywhere else. Schools such as Mowlem Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.

Why it’s worth doing now in Cambridge Heath
Sealant work is quick by the room: it takes a morning for a small washroom, and a planned programme for bigger sites. After that, each area needs its cure time before use, so the programme is planned around cure times. In a flat in Cambridge Heath, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

How we quote for commercial sealant
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- Any mould that needs treating
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
What we need to know
You do not need to know the technical terms. Just tell us:
- The rough size of the job
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- If someone has resealed it before
For commercial sealant in Cambridge Heath, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.
