When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Leaks through tanking or membranes below the finishes
- Swollen or delaminated boards behind panels or vanity tops
- Loose panels, vanity units or tiles, which need fixing first
If in doubt, ring 01277 525 020 or use the quote form and we’ll say what we think.
Joints and surfaces we work on
- Showers, trays and wet room floors
- Vanity units and basins
- IPS panels and cubicles
- Accessible toilets and changing rooms
- Kitchens and tea points
- Urinals and WCs
Washroom sealing in Aldgate, done properly
Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. We work on IPS panels and cubicles, accessible toilets and changing rooms and urinals and WCs, and the failures we are asked to look at most are gaps where vanity tops meet the wall and split or peeling sealant at shower trays. Looking for mastic applicators who cover Aldgate? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Many London buildings can’t close every toilet at once. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Other services in Aldgate
Commercial washrooms in Aldgate
The 2 miles around Aldgate include nine care or nursing homes. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Work is agreed with the manager, around residents’ routines. A London building with hundreds of occupants can’t lose every washroom for a day, so we take one block of facilities out of use at a time.
On a healthcare site such as London Bridge Hospital, 0.6 miles to the south-west of Aldgate, washroom work starts with the infection-control team’s sign-off. For a campus such as London Metroplitan University: Aldgate Campus, less than half a mile to the north-east of Aldgate, showers in residences and washrooms in teaching blocks can be programmed around term dates. If you manage an office at a site such as Princes Court Business Centre, 0.9 miles east of Aldgate, the washrooms and tea points can be done a floor at a time.

Why act early in Aldgate
When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. In Aldgate, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

How the job changes by surface
Kitchens and tea points
We plan kitchen sealing around when the kitchen is in use. Tell us your site hours and access windows and we’ll plan around them.
Wet-room floors and floor-to-wall joints
Wet floors are common in accessible showers and changing rooms, so their perimeter joints get close attention.
Our process
Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First, the phasing is agreed so facilities stay open.
- Leaks, loose panels or damp are pointed out first.
- Old sealant is stripped and the faces prepared.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.
Before we start on site
- Tell staff and tenants when we’ll be in
- For older buildings, check the asbestos register before work
- Move anything stored against the joints

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Questions we’re asked in Aldgate
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Can work in a care setting near Aldgate go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you guarantee washroom sealing?
A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
Will cleaning remove black mould from sealant?
Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
