Looking after the joints
Regular inspection catches problems early. In particular:
- Respect the cure time before reopening each room
- Add sealant joints to planned maintenance checks
- Don’t leave an open joint at a basin or tray
- Squeegee showers and trays after busy periods
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, regular checks keep small problems small.
Mouldy sealant only gets harder to ignore and users notice. Replacing it early keeps the job to a reseal.
Quoting for work in Strawberry Hill
The price varies from site to site. Expect it to depend on:
- Phasing around occupants
- The size and state of each joint
- How much existing material needs removing
- How accessible the joints are
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- Anything awkward about access or site hours
- Asbestos survey details if the building is older
- Any dates the work must fit around
- The postcode of the building

Building owners, agents and FMs in Strawberry Hill
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
On site: what to expect
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits. In Strawberry Hill, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- Old sealant is removed completely and the faces cleaned.
- Each joint is cleaned and left dry.
- New anti-mould sealant goes in and is tooled neat.
- Each area is handed back when ready.
Getting the site ready
- Share your working hours and any access restrictions
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use

Sanitary sealant for Strawberry Hill buildings
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. Strawberry Hill has a good number of hotels close by, all within 2 miles. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. Rooms are done in turn so most stay available.
Student showers at universities like St Mary's University, under half a mile south of Strawberry Hill, see more use than most, and their silicone shows it. Toilets at colleges like Richmond-upon-Thames College, 1 mile to the north of Strawberry Hill, take heavy use from students and staff alike.
Strawberry Hill is about 1 mile south of Twickenham, in Greater London. Any commercial site in Strawberry Hill is covered, for single jobs and planned programmes alike. Across Greater London, 764 places are covered, Strawberry Hill among them. Our London page has more on work in that area.

Strawberry Hill: questions and answers
Is hospital work, at somewhere like Teddington Memorial Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can work at a site such as St Mary's University fit around teaching?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Will all the toilets be closed at once?
Only the area we are working in is closed. Each room reopens after the sealant’s cure time and we start the next.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Do you cover Strawberry Hill?
Yes. We take on work across Strawberry Hill.
What we are called out for in Strawberry Hill
Mop buckets, trolleys and knocks from users damage joints near the floor, especially at floor edges and around urinals and WC pans.
Any of the following is a good reason to get the joints checked over:
- Mould spotting along silicone joints
- Urinal joints that look unhygienic
- Washrooms that look worn because of the sealant
- Stained or open joints at kitchen sinks and worktops
Office toilets at parks like Newmans Shipyard & Business Park, less than half a mile north-east of Strawberry Hill, take steady weekday use, and mouldy silicone soon shows.

When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Water from plumbing, not from a joint
- Loose panels, vanity units or tiles, which need fixing first
- Failed tanking beneath a wet-room floor or behind tiles
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly before you book.
