Washroom sealing across Newington Green
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Washroom sealing in Newington Green, done properly
Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. If you have mould spotting along silicone joints and failed joints along IPS and cubicle panels, we can put it right. Whoever orders the work in Newington Green, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Building managers in Newington Green normally need some facilities open throughout. We work through washrooms floor by floor or core by core, at times agreed with you, so staff and visitors can always find an open washroom.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Do you need washroom sealing in Newington Green?
Washrooms are warm, damp and full of organic residue, and sealant joints trap all three. Even anti-mould grades can be colonised over time where extraction is poor.
Common reasons buildings call us in:
- Open joints along basins and vanity units
- Stained or open joints at kitchen sinks and worktops
- Users noticing mouldy joints
- Panel joints letting water behind
On an industrial estate such as Frogmore Industrial Estate, 0.5 miles to the west of Newington Green, staff toilets, showers and canteens are where sanitary sealant takes the most wear.
What your quote should include
- Do they follow the manufacturer’s priming guidance?
- How long is the guarantee, and what does it include?
- The named product and why it was chosen
- Can the work be phased to keep areas open?
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Loose panels, vanity units or tiles, which need fixing first
- A dripping waste or valve behind a panel
- Mould caused by poor ventilation, which will return until the extract is fixed
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

FAQs: Newington Green
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Can you take on a job at a hospital such as Moorfields Eye Hospital (City Road campus)?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Is it OK to put new silicone on top of the old?
The failed bead is always removed. New silicone won’t stick to the old so a bead over the top fails quickly.
Is it possible to just clean mouldy silicone?
Not for long. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.
How the job changes by surface
IPS and cubicle panels
Panels flex slightly in use so the bead needs to cope with it. Loose panels are flagged before any sealant goes on.
Showers and trays
In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Every joint is stripped, degreased, dried and given a new bead.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a job in Newington Green, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
