Washroom sealing for commercial buildings in Stoneleigh
Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Our workmanship is guaranteed for 12 months. We work on vanity units and basins, IPS panels and cubicles and showers, trays and wet room floors, and what we’re called in for most is sealant lifting along a tray edge and kitchen worktop joints that can’t be kept clean. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Stoneleigh is the same: the right product in a properly prepared joint.
A place of Stoneleigh’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around Stoneleigh need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- Every room is surveyed and the failed joints listed.
- You get a fixed quote with the phasing plan.
- Old sealant is removed completely and the faces cleaned.
- Joints are degreased and dried.
- New anti-mould sealant goes in and is tooled neat.
- Rooms reopen after the cure time.
Preparing the site
- Point out any areas we must not close
- Flag any permit to work we will need
- Clear stock, furniture or equipment away from the joints
Request a quote
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

What affects the price in Stoneleigh
Each job is priced on its own details. The main factors are:
- Whether the work must be split into stages
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- The type of building and who uses it
- Photos of the joints, close up and from further back
- Any dates the work must fit around
- The site address and postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
Work for main contractors and building owners
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Make sure washroom ventilation is running
- Respect the cure time before reopening each room
- Squeegee showers and trays after busy periods
- Add sealant joints to planned maintenance checks
Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades, so get faulty extract looked at.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
Questions about Stoneleigh
Do hotels near Stoneleigh have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.
Would you work within a site like St. Ebba's Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
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 a bead over the top fails quickly.
Can you quote from photographs?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
Is it possible to just clean mouldy silicone?
Typically not. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacement is the lasting fix.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Do you work in Stoneleigh?
Yes. We take on work across Stoneleigh, with one number for every area we cover.
Washroom sealing around Stoneleigh: points for this area
Central London is about 11 miles from Stoneleigh, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time. There are two care or nursing homes within about 2 miles of Stoneleigh. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Rooms are done a few at a time at times agreed with the home.
For an occupier at a site such as Longmead Industrial Estate, 1.6 miles to the south-west of Stoneleigh, the canteen and welfare facilities need cleanable joints as much as any office.

Customer toilets in retail centres such as The Ashley Centre, 2.4 miles to the south-west of Stoneleigh, rarely close, so resealing is phased.

Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Why deal with it now?
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 smaller place such as Stoneleigh, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
