How we handle washroom sealing in Pimlico
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. The enquiries we see most involve washrooms that look worn because of the sealant and split or peeling sealant at shower trays, on urinals and WCs, accessible toilets and changing rooms and showers, trays and wet room floors. Whoever orders the work in Pimlico, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Smaller places such as Pimlico still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or use the quote form and we will arrange a return visit.

Why act early in Pimlico
Washrooms shape how visitors judge a building. Visitors notice black sealant before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Converted and older buildings near places like Pimlico tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep extract fans working and vents clear
- Don’t leave an open joint at a basin or tray
- Don’t leave trays and floors sitting wet
- Note failing joints building by building
Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.
In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Pimlico can be grouped with others nearby. A fixed quote is given before anything starts.
- We survey each room, count the joints and note anything behind them that needs another 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.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.

Washroom sealing in Pimlico: the local picture

The work can go floor by floor, agreed with housekeeping. At about 21 miles from central London, Pimlico is within reach of the capital, in a commuter belt where offices and business parks are common. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time.

In a centre such as The Heights Shopping Centre, 2.9 miles north-west of Pimlico, public washrooms are resealed a block of facilities at a time.

Site staff or a sealant specialist?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Common questions from Pimlico clients
Must a hotel around Pimlico close while you work?
Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.
Can you work on a hospital site such as Hemel Hempstead Hospital?
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.
Do you guarantee washroom sealing?
A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
Can you reseal washrooms in healthcare buildings?
We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Loose panels, vanity units or tiles, which need fixing first
- Water escaping beneath the floor rather than through a joint
- Panel boards already damaged by water
If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
