Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Trowley Bottom, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- Every room is surveyed and the failed joints listed.
- The fixed quote sets out the rooms, the products and the phasing.
- Old sealant is removed completely and the faces cleaned.
- Joints are degreased and dried.
- A sanitary silicone bead is laid and given a smooth tooled finish.

Washroom sealing in Trowley Bottom, done properly
When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. We work on urinals and WCs, showers, trays and wet room floors and accessible toilets and changing rooms, and the usual reasons a site gets in touch are mould spotting along silicone joints and kitchen worktop joints that can’t be kept clean. Whoever orders the work in Trowley Bottom, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller places such as Trowley Bottom 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.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Looking after the joints
A few simple habits keep the new joints working:
- Brief cleaning staff to treat joints gently
- Include joints in routine washroom inspections
- Keep extract fans working and vents clear
- Note failing joints building by building
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 complaints follow. Replacing it early keeps the job to a reseal.
Questions about Trowley Bottom
Is Trowley Bottom too small for you to travel to?
Not at all. Trowley Bottom is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you take on a job at a hospital such as Hemel Hempstead Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can washrooms stay open while you work?
The work is phased so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators.
Can you clean the mould off instead of resealing?
Usually not. The mould is inside the silicone so cleaning only lightens it for a while. Replacing the bead is the lasting answer.
Different surfaces, different methods
Basins and vanity tops
A failed joint along a vanity unit lets water into the carcass. Prompt resealing keeps the unit sound.
Wet-room floors and floor-to-wall joints
Floor edges in wet areas are where water most often escapes. Floor perimeters and sealant joints near drains are resealed.

Quoting for work in Trowley Bottom
We price every job individually. The things that drive the figure:
- Joint width, depth and condition
- Access and working height
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
What to include in your enquiry
However big the job, these details speed things up:
- Any dates the work must fit around
- The asbestos register, for older buildings
- How the joints are reached, and at what height
- The postcode of the building
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Condensation from failed extract fans
- Panel boards already damaged by water
- Loose panels, vanity units or tiles, which need fixing first
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly.

General trades versus a specialist
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. That’s why many clients bring in a specialist from the beginning.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
