How we handle commercial sealant in Chase Cross
Mr Mastic brings more than 20 years’ experience to commercial sites, and we are fully insured and ARBOMaster approved. If your site needs RAMS or insurance details, tell us, and we will confirm what we can supply with the quote. We work on hotel bathrooms, retail & leisure sites and student & care accommodation, and common reasons people get in touch are worktop sealant that has shrunk and stained and silicone laid over old silicone by a previous contractor. Some people call us the mastic man, others the silicone man or the sealant specialist, but the work in Chase Cross is the same: old material out, joints prepared and the right product used.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Chase Cross, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Why act early in Chase Cross
A quick bead over the old sealant might get a room back in use today, but silicone doesn’t bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Chase Cross, the repair is bigger than the sealant job would have been.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas

Signs you need commercial sealant in Chase Cross
A rushed reseal between guests rarely lasts. New silicone over old, joints that weren’t dried, or an unsuitable product means the joint fails again soon.
If you can see any of these, it’s time to have the joints looked at:
- Mouldy washroom sealant that staff and guests notice
- Joints that need doing before an inspection or audit
- Mouldy bathrooms flagged at a tenancy check
- Leaking joints in shower rooms and changing areas
Community buildings like St James are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.

Common questions in Chase Cross
I let a flat near Gidea Park station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 07833 053749 or email us with the address and what needs doing, and we will give you a clear quote.
Do you cover Chase Cross for commercial sealant?
Yes, Chase Cross is within the area we cover. Our work covers London and the South East. You can call 07833 053749 or send us an email and tell us what needs doing.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How do I get a quote for commercial sealant in Chase Cross?
Every job is different, so each one gets its own quote. To get one, phone 07833 053749 or email us and let us know what needs doing and where.
Can you reseal every bathroom in a hotel?
Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, keeping most of it in use.
Is out-of-hours working possible?
Out-of-hours work and early starts can be arranged. Tell us what you need when you ask for a quote.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The process
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. It normally takes as long as the scope needs, from one welfare room to a full building. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- 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.
- Rooms are handed back in order, each with its cure time.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
Ask for a quote
We quote each job on its own, so start by telling us what you need. Simply ring 07833 053749 or email us and describe the job and send pictures if you have them.
