Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Water from plumbing, not from a joint
- Swollen or delaminated boards behind panels or vanity tops
Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly.

How we handle washroom sealing in Kingsbury
In a busy washroom, the sealant usually gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. If you are dealing with discoloured joints around urinals and WC pans and gaps where vanity tops meet the wall, we can put it right, on vanity units and basins, kitchens and tea points and showers, trays and wet room floors alike. Facilities teams, main contractors and managing agents in Kingsbury tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

After the work
After handover, these steps help:
- Don’t leave an open joint at a basin or tray
- Clear standing water from shower floors where possible
- Leave signs up until the cure time is over
- Include joints in routine washroom inspections
Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.
In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
Different surfaces, different methods
Showers and trays
Shower trays move under foot and are wet all day. Tray perimeters are a frequent source of leaks.
Urinals and WC pans
We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.
What affects the price in Kingsbury
Each job is priced on its own details. The things that drive the figure:
- Distance, for remote addresses
- Which sealant the job calls for
- Backing rod, priming and other preparation
- Whether the work must be split into stages
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Details that help us quote
It doesn’t need to be a full survey. A few details are enough to get going:
- A wide shot and a close-up of the area
- Access details, including height
- The product your specification calls for
- Whether an asbestos survey exists
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, call the office on 01277 525 020 or email us.
Why it’s worth doing now in Kingsbury
Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on 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. In Kingsbury, most buildings stay in use during the work, 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.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Preparing the site
- Tell us which areas need to stay in use
- Send any specification or drawings in advance
- Tell staff and tenants when we’ll be in
