Washroom sealing in Southborough
Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, 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. Site teams most often ask us about panel joints letting water behind and a new bead over an old one coming away, on kitchens and tea points, vanity units and basins and IPS panels and cubicles. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Southborough it comes down to the same thing: the right product in a properly prepared joint.
In Southborough, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Southborough: questions and answers
Do you work in occupied care homes around Southborough?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
Could you schedule work at a campus like University of Greenwich - Avery Hill for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is it possible to just clean mouldy silicone?
Typically not. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacement is the lasting fix.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How much does the work cost?
We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.
Do you cover Southborough?
Yes. Southborough is in our area and the rest of Greater London. To discuss a job, give us a call on 01277 525 020 or email the details over.

Commercial washrooms in Southborough
A London building with hundreds of occupants can’t lose every washroom for a day, which is why the work is split into phases agreed in advance. There are 11 care or nursing homes within about 2 miles of Southborough. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. We plan the work with the manager so residents are disturbed as little as possible.
Healthcare estates like Princess Royal University Hospital (to the south of Southborough) expect contractors to follow their permits and cleaning rules in every washroom. In a centre such as The Mall, 1.5 miles to the north-west of Southborough, public washrooms are resealed a block of facilities at a time. At a college such as Bromley College, 0.5 miles to the south-west of Southborough, washroom and kitchen sealant is best renewed in the holidays or in phases during term.
Southborough is about 2 miles south-east of Bromley, in Greater London. Businesses, contractors and managing agents in Southborough can call on us for washrooms and wet areas.

What affects the price in Southborough
Each job is priced on its own details. The things that drive the figure:
- Whether the work must be split into stages
- Quantities, in metres or numbers
- Backing rod, priming and other preparation
- Location, for remote and island sites
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Your programme or deadline
- The product your specification calls for
- The site address and postcode
- A wide shot and a close-up of the area
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
What happens if it’s left?
Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Take a look at how commercial sealant jobs are priced and our accreditations.
Surface by surface
Changing rooms and gyms
Shower areas, wet floor edges and vanity areas all have sealant joints and we look at them as one job.
Wet-room floors and floor-to-wall joints
Changing rooms and accessible showers often have wet floors so the edges are checked carefully.
How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Before we start on site
- Tell staff and tenants when we will be in
- Share your working hours and any access restrictions
- Send asbestos survey details if the building is pre-2000

Related advice
After the work
To get the most from the new sealant:
- Inspect washroom sealant regularly
- Respect the cure time before reopening each room
- Mention any site permits or estates rules at quote stage
- Report split joints at trays and basins early
Each room goes back into use only when the sealant has cured enough. You will be told when showers and basins can be used again and signage stays in place until that time.
Mouldy sealant only gets harder to ignore, and complaints follow. Replacing it early keeps the job to a reseal.
