Morden: your questions answered
Can you help a landlord with a rental near St Helier station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Can you do commercial sealant in Morden?
Yes. Our work covers London and the South East, and Morden is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can you work around guests in a hotel?
Yes, in most cases. Each visit covers an agreed batch of rooms, working around check-out and check-in where possible.
Can new sealant go over the old?
No. The old sealant always comes out first.
What does commercial sealant cost?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Commercial sealant in Morden
Mr Mastic brings more than 20 years’ experience to commercial sites, and we’re fully insured and ARBOMaster approved. If your site needs RAMS or insurance details, tell us, and we will confirm what we can provide. If you have leaks from showers into rooms or ceilings below and rental bathrooms that need resealing between tenants, we can help.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Morden cannot close.
All our work is covered by a one-year guarantee.

Why act early in Morden
First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and scrubbing won’t fix it. New sealant does. 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 Morden.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Why book with us
- A choice of colours where the product allows
- More than 20 years in sealant work
- An ARBOMaster approved applicator
- 12-month guarantee on every job

How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes as long as the scope needs, from one welfare room to a full building. In Morden, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Tell us the rooms, hours and site rules, and we’ll 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.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Leave squeegees in busy showers
- Keep a record of which rooms were resealed and when
- Add sealant to your planned maintenance checks
- Use mild cleaners on sealant, not bleach or abrasives
Each room is handed back with its cure time, usually around 24 hours. Pass it on to housekeeping or cleaners so nobody showers or cleans the joint too early.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, so the fix is replacement.

What commercial sealant looks like in Morden
London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
Rented homes near St Helier station change hands often, and we can quote for one property or a whole portfolio of rentals. For site and facilities teams at buildings such as Morden Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. For buildings such as St Lawrence Church, any kitchen and washrooms need the same sealant care as any other building.

We also work for property managers and facilities teams in Morden and across Greater London. Several sites can go on one quote, and we’re fully insured.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What sealant work cannot fix
We will not take on work that will not last, so these are the limits:
- Water coming from plumbing rather than sealant
- Certifying fire stopping or building compliance
- Damaged sanitaryware that needs replacing
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Office washrooms & kitchens
- Welfare facilities
- Hotel bathrooms
- Student & care accommodation
- Retail & leisure sites
- Rental portfolios
Surface by surface
Hotel bathrooms
We work through hotel rooms in agreed batches, keeping most of the hotel open. Each room is handed back with its cure time for housekeeping.
Rental portfolios
An empty property is easy to reseal, so the next tenant moves in to clean, sound joints.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you are 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 does not work out, we can still put it right.
