When to call us in Headstone
Internal washrooms and en suites without a window rely entirely on extraction, so if the fan is weak, steam lingers and the sealant stays damp. Mould then takes hold in the silicone.
Any of these means the joints need attention:
- Washrooms that need sorting before an inspection
- Rental bathrooms that need resealing between tenants
- Large numbers of bathrooms needing the same work
- Leaks from showers into rooms or ceilings below
As a London address, Headstone can be tricky for parking: let us know about parking bays, permits or a driveway.

Commercial buildings in Headstone
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.
Rented homes near Headstone Lane station change hands often, and several rental properties can be resealed on one programme. Schools such as Pinner Park Primary School are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours.

Headstone: your questions answered
Can you do commercial sealant in Headstone?
Yes, Headstone is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Can parking be tricky for a visit in Headstone?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is out-of-hours working possible?
Often, yes. Tell us your opening hours and quiet times, and we’ll plan the work around them.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours for a single washroom, longer for a whole building. We’ll tell you when we quote.
Landlord and commercial work in Headstone
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Include the silicone on your room checklists
- Plan resealing around quiet periods
- Use mild cleaners on sealant, not bleach or abrasives
- Leave squeegees in busy showers
Make it easy for staff to flag a failing joint. Catching one split early can save a leak later, and if anything looks wrong, just phone 0345 464 0079 or email us.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.

What else we do in Headstone
How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours per area, with larger sites planned over several visits. In Headstone, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We start with a site walk to agree the rooms and the timing.
- Room by room, we protect the area and remove all the old sealant.
- We clean the joints, treat any mould and let them dry.
- New sealant suited to each area is applied and tooled.
- Rooms are checked and returned with a cure time so staff know when to use them.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit

Advice
Why deal with it now?
Room by room, the work is quick: it takes a few hours for a single washroom, longer for a whole building. Each area is then left to cure for the time we give you, so the programme is planned around cure times. 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 Headstone.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
