About our washroom sealing in Single Street
Whether it’s a single toilet block in Single Street or a programme across several buildings, the route is the same: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. Site teams most often ask us about a new bead over an old one coming away and stained or open joints at kitchen sinks and worktops, across kitchens and tea points, vanity units and basins and urinals and WCs. A specialist sealant contractor works differently from a general builder: in Single Street, that means joint design, primers and backing rod as standard.
In Single Street, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Travel to remote or island sites
- Removal of failed or old sealant
- Any access equipment needed
- The total length or number of joints
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:
- Asbestos survey details if the building is older
- The site address and postcode
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or email a schedule or drawings.

Advice
Single Street: questions and answers
Do we have to close all our washrooms in Single Street for resealing?
Typically only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.
Do you take on jobs in Single Street where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Is Single Street in your area?
Yes. We cover Single Street, and you can phone 01277 525 020 or email the details over to get started.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Respect the cure time before reopening each room
- Note failing joints building by building
- Keep extract fans working and vents clear
- Inspect washroom sealant regularly
Ventilation is half the battle. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.
Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.
What happens if it’s left?
Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Keeping Single Street washrooms open while we work
A London building with hundreds of occupants can’t lose every washroom for a day, so resealing goes floor by floor, agreed with the facilities team.
Pupil toilets at schools like Cudham Church of England Primary School take heavy daily use, and the holidays give the window to reseal. Staff changing rooms and patient toilets at places like Princess Royal University Hospital (to the north of Single Street) need cleanable, sound silicone. At a hotel such as The Landing Hotel, 1.4 miles west of Single Street, the quieter weeks are the time to reseal bathrooms.

How the job changes by surface
Basins and vanity tops
Vanity tops and basins are splashed all day, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.
IPS and cubicle panels
IPS panels and cubicle systems have joints at the wall, the floor and the worktop. They stop water reaching the panel boards.
