Should maintenance staff do it?
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
How we handle washroom sealing in Woolwich
When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you have black mould inside silicone joints that cleaning can’t shift and open joints at the base of cubicle panels, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Woolwich, preparation and product choice get the time they need.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Keeping the joints sound
For the best life from the joints:
- Keep washrooms out of use until we say the sealant has cured
- Report split joints at trays and basins early
- Squeegee showers and trays after busy periods
- Include joints in routine washroom inspections
Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.
Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.
Your questions answered
Can work in a care setting near Woolwich go ahead while residents are there?
Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Will cleaning remove black mould from sealant?
Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Sanitary sealant for Woolwich buildings
Woolwich has plenty of hotels close by, all within 2 miles. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. In London buildings, toilets and showers generally need to stay partly open, so we take one block of facilities out of use at a time.
Clinical washrooms at sites like Queen Elizabeth Hospital, 1 mile to the south-west of Woolwich, are scheduled with the ward so the room is out of use for as little time as possible. On an industrial estate such as Woolwich Dockyard Industrial Estate, 0.5 miles to the north-west of Woolwich, staff toilets, showers and canteens are where sanitary sealant takes the most wear. In a centre such as Stone Lake Retail Park, which lies west of Woolwich, public washrooms are resealed a block of facilities at a time.

How a job runs
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- 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.
What we need from you
- Make sure the joints can be reached
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

How the quote is worked out
Before we quote, we look at:
- How accessible the joints are
- The product specified
- Joint width, depth and condition
- Removal of failed or old sealant
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- Approximate linear metres or a joint schedule
- How the joints are reached, and at what height
- Any dates the work must fit around
- The postcode of the building
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
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Failed tanking beneath a wet-room floor or behind tiles
- Hollow tiles or loose panels behind the joint
- Condensation from failed extract fans
If you are not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer before you book.
