Washroom sealing for businesses in Barking
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Keep washrooms out of use until we say the sealant has cured
- Keep extract fans working and vents clear
- Photograph and log failed joints across the estate
- Add sealant joints to planned maintenance checks
Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.
Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.
How we handle washroom sealing in Barking
Accessible toilets, shower rooms and changing rooms have joints that work harder than most: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels so they get particular attention. If you have a new bead over an old one coming away and sealant lifting along a tray edge, we can help. Looking for mastic applicators who cover Barking? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Cost factors for washrooms and wet areas
What shapes the price:
- Site requirements such as inductions and permits
- Travel to remote or island sites
- Joint width, depth and condition
- Any access equipment needed
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:
- Any specification or named product
- Anything awkward about access or site hours
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, ring 01277 525 020 or email the details over.
What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Vanity carcasses that have swollen
- A room that stays damp because ventilation isn’t working
- Water escaping beneath the floor rather than through a joint
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
What we seal
- Showers, trays and wet room floors
- Vanity units and basins
- Accessible toilets and changing rooms
- Kitchens and tea points
- IPS panels and cubicles
- Urinals and WCs
Why it’s worth doing now in Barking
Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
A quote for washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Why us?
- Coloured sealants to suit the setting, where available
- Fully insured, including public liability cover
- One phone line for London, the South East and Scotland
- 12 months’ guarantee on every job
Questions about Barking
Can work in a care setting near Barking 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.
Do you take on jobs in Barking where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Is there a guarantee on the work?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
Is it OK to put new silicone on top of the old?
The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.
Toilets, showers and kitchens around Barking
London offices and hotels typically can’t close all their washrooms at once, so we phase the work core by core or floor by floor with the building manager. Barking has a number of hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later.
Colleges such as The Adult College (0.7 miles north-east of Barking) have toilets, changing rooms and catering kitchens that can be resealed around term dates. Office toilets at parks like Lyon Business Park, under half a mile to the south of Barking, take steady weekday use, and mouldy silicone soon shows. At a university such as University of East London, which lies south-west of Barking, summer is the usual window for resealing residence bathrooms.

Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- We agree which rooms close and when, so users always have somewhere to go.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Joints are cleaned, degreased and dried before sealing.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
What we need from you
- Warn occupants and staff about the work
- Make sure the joints can be reached
- Confirm the product named in the specification

Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
