When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Water escaping beneath the floor rather than through a joint
- Panel boards already damaged by water
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think.

Washroom sealing in Sydenham Hill, done properly
In healthcare and care settings, sealing is part of keeping surfaces cleanable. We work to your organisation’s estates and infection-control requirements and any site permits. Tell us what records you need and we’ll confirm with the quote. Site teams most often ask us about panel joints letting water behind and stained or open joints at kitchen sinks and worktops, across urinals and WCs, IPS panels and cubicles and accessible toilets and changing rooms. Most enquiries from Sydenham Hill start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Building managers in Sydenham Hill typically need some facilities open throughout. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand, so staff and visitors can always find an open washroom.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Questions we are asked in Sydenham Hill
Do you take on jobs in Sydenham Hill where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Must a hotel around Sydenham Hill close while you work?
Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.
What guarantee comes with washroom resealing?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you cover Sydenham Hill?
Yes. Sites across Sydenham Hill are covered.
Is old silicone taken out first?
The failed bead is always removed. New silicone won’t stick to the old, so sealing over it soon peels.

On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. In Sydenham 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.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- We clean and dry every surface so the new sealant can grip.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Rooms reopen after the product’s cure time, and we move to the next.

What affects the price in Sydenham Hill
The price varies from site to site. It mainly depends on:
- The total length or number of joints
- The size and state of each joint
- Site requirements such as inductions and permits
- Working within restricted access windows
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Sending details for a quote
A few photos plus some basic facts will normally do. It helps to include:
- Access details, including height
- Whether an asbestos survey exists
- Any dates the work must fit around
- Where the site is, with the postcode
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or send photos by email if you’d rather talk the job through.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Photograph and log failed joints across the estate
- Report split joints at trays and basins early
- Keep washrooms out of use until we say the sealant has cured
- Tell us about infection-control or permit rules before we quote
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface over time.
Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
