Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Washroom sealing in Pentonville, done properly
Whether it’s a single toilet block in Pentonville or a programme across several buildings, the route is the same: details first, then a fixed quote, then the work, then the 12-month guarantee. A few photos and a count of fittings are enough for a quick quote, or we can arrange a visit. Site teams most often ask us about urinal joints that look unhygienic and failed sealant behind washroom basins, across urinals and WCs, IPS panels and cubicles and kitchens and tea points. A specialist sealant contractor works differently from a general builder: on jobs in Pentonville, preparation and product choice get the time they need.
In a London area such as Pentonville, commercial washrooms in offices, hotels and leisure buildings see constant use. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Advice
Questions we are asked in Pentonville
Can you work on a hospital site such as Moorfields Eye Hospital (City Road campus)?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work around term dates at a campus such as Paris Dauphine University - London Campus?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Is colour matching possible?
It depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
Is old silicone taken out first?
The failed bead is always removed. New silicone won’t stick to the old, so sealing over it soon peels.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What affects the price in Pentonville
The price varies from site to site. Expect it to depend on:
- Any access equipment needed
- Site requirements such as inductions and permits
- Distance, for remote addresses
- Backing rod, priming and other preparation
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you’re ready.
What to include in your enquiry
We can often quote from photos and a few details. Please tell us:
- Rough lengths or quantities, or drawings if you have them
- Clear photographs of the problem areas
- Where the site is, with the postcode
- What the building is and how it’s used
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, phone 01277 525 020 or use the quote form.
Do you need washroom sealing in Pentonville?
Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.
It’s worth sending us details if you spot any of the following:
- Panel joints letting water behind
- Washrooms that look worn because of the sealant
- Split or peeling sealant at shower trays
- A new bead over an old one coming away
Healthcare washrooms on sites such as Moorfields Eye Hospital (City Road campus) (to the south-east of Pentonville) are resealed area by area, under the site’s own infection-control rules.

How the job changes by surface
Kitchens and tea points
In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Food-safe sealants are used where food may touch the joint.
Showers and trays
If a tray moves too much or is cracked, it needs attention first, and we will say so before resealing.

Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Squeegee showers and trays after busy periods
- Report split joints at trays and basins early
- Respect the cure time before reopening each room
- Keep a record of which washrooms need attention
Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.
A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.
