Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Leave it or put it right?
Refitting a washroom is a big, disruptive project. When the fittings are sound, renewing the sealant brings it back with far less upheaval. If something else is wrong, we will say so. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Ham.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
Why book with us
- Tidy, careful work
- Anti-fungal silicone where joints get wet
- Over 20 years’ experience
- 180+ five-star Google reviews
Take a look at what affects the cost and customer reviews.
How to look after the new joints
So the new joints stay in good condition:
- Report broken fans quickly
- Keep strong chemicals and scourers off the joints
- Keep a record of which rooms were resealed and when
- Don’t leave a failed joint until the next refurbishment
Add sealant checks to your planned maintenance. Checking joints alongside other room checks catches failures before they leak.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, and only replacement fixes it.
What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the number of rooms. For a job in Ham, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First we visit and agree the scope, the sequence and the working hours.
- Room by room, we protect the area and remove all the old sealant.
- Joints are cleaned, treated for mould and dried.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Different surfaces, different methods
Retail & leisure sites
Changing areas and showers at leisure sites are wet all day, so joints are sealed with anti-fungal sanitary silicone.
Student & care accommodation
In care settings, we agree the order and timings with staff, with each bathroom handed back with its cure time.
Commercial sealant around Ham
Ham has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. London’s water is hard, so limescale builds up on sealant, grout and fittings.
If you look after a church, hall or community building such as Ham Christian Centre, any kitchen and washrooms need the same sealant care as any other building. For landlords with property near Teddington station, we can quote for one property or a whole portfolio of rentals. For site and facilities teams at buildings such as Meadlands Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.
Ham is about 1 mile south-east of Twickenham, in Greater London. Across the TW10 area, we cover commercial sealant for homes and businesses. Our area takes in 764 places across Greater London, large and small. There’s also a page for London, about 10 miles away.
All of TW10, KT2 and TW11 is within our area for commercial sealant. We cover properties on New Road, Lock Road and Cave Road and the roads around them. Ham sits on or near the A307, which makes travel easy. Nearby, we also carry out commercial sealant in Petersham (1 mile north), Eel Pie Island (1 mile north-west), Strawberry Hill (1 mile west), Teddington (1 mile south-west) and Richmond (1 mile north). Within a short drive, we also cover London (10 miles north-east), City of Westminster (9 miles north-east), Marylebone (9 miles north-east), Kensington (6 miles north-east), St Pancras (10 miles north-east) and Shoreditch (12 miles north-east).
Local landmarks in Ham
Locally, jobs take us to homes and businesses close to Grey Court School, The New Inn Public House and Sudbrook Park. The nearest railway station is Teddington station, roughly 1.2 miles south-west. Nearby you’ll also find Eel Pie Island Museum (1.1 miles north-west) and Bentall Centre (1.6 miles south). For a walk, there’s Kew Gardens Lake and Richmond Hill.
Ham: your questions answered
Do you work in hotels near Ham?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can you help a landlord with a rental near Teddington station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Do you come to Ham?
We do. Ham is part of the area we cover, and the service is the same as everywhere else.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where is Mr Mastic based?
We work from Crawley. We cover Ham and the rest of Greater London, along with the rest of our area.
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 I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
What we cannot put right
We will not take on work that will not last, so these are the limits:
- Assessing what fire stopping a building needs
- A shower tray, bath or basin that’s cracked or broken
- Failed tanking or loose tiles behind the sealant
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
What we seal
- Hotel bathrooms
- Welfare facilities
- Retail & leisure sites
- Student & care accommodation
- Rental portfolios
- Office washrooms & kitchens
What affects the cost of commercial sealant
Jobs vary more than people expect. What affects the quote:
- Access and height
- Whether there’s mould to deal with
- Any working-time requirements on site
- The old material and how stubborn it is
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
Asking for a quote
To make quoting easier, please include:
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- A few photos by email, if you can
For a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.
