Washroom sealing in Rickmansworth
Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. Most enquiries involve black mould inside silicone joints that cleaning can’t shift and discoloured joints around urinals and WC pans, on vanity units and basins, showers, trays and wet room floors and IPS panels and cubicles. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Rickmansworth, that means joint design, primers and backing rod as standard.
Schools in towns like Rickmansworth typically want washrooms and changing rooms done in the holidays, while offices and care homes need phased work. Let us know your opening times and any access limits, and we will work to them.
Every job we finish is backed by a 12-month workmanship guarantee, in Rickmansworth as everywhere else we work. If our installation lets you down in that time, we return and fix it.

From enquiry to sign-off
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Town-centre premises in Rickmansworth may have limited parking, so tell us what’s nearby. On estates and business parks it’s usually simpler.
- We inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- The whole of the old bead is removed.
- Joints are degreased and dried.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Each area is handed back when ready.
Preparing the site
- Point out any areas we must not close
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000

Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Loose panels, vanity units or tiles, which need fixing first
- Water escaping beneath the floor rather than through a joint
If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think.
What we seal
- Vanity units and basins
- Urinals and WCs
- Showers, trays and wet room floors
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Kitchens and tea points
Signs you need washroom sealing in Rickmansworth
Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.
Things that usually lead to an enquiry:
- Kitchen worktop joints that can’t be kept clean
- Black mould inside silicone joints that cleaning can’t shift
- Gaps where vanity tops meet the wall
- A new bead over an old one coming away
Pupil toilets at schools like Saint Joan of Arc Catholic School take heavy daily use, and the holidays give the window to reseal.

Rickmansworth: questions and answers
Can you work around term dates at a campus such as West Herts College?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is a hospital such as Harefield Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Will all the toilets be closed at once?
The work is phased so there are always facilities open. We work through the building a room or section at a time around your site hours and access windows.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you clean the mould off instead of resealing?
Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.
Wet areas in Rickmansworth’s workplaces
Rickmansworth is about 19 miles from central London. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.
Where you’re responsible for a hall attached to a building such as Church of St Mary, its kitchen and toilets need sealant that stays cleanable. At a college such as West Herts College, which lies north-east of Rickmansworth, washroom and kitchen sealant is best renewed in the holidays or in phases during term.

How the quote is worked out
The price varies from site to site. Expect it to depend on:
- Location, for remote and island sites
- Induction, permit and paperwork requirements
- Working within restricted access windows
- Specialist products, such as fire-rated or hygienic sealants
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
- The product your specification calls for
- When you need the work done
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Leave it or put it right?
A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints before they notice much else. Resealing is a modest task with a very visible payoff. In a town like Rickmansworth, a split, stained or mouldy joint is often the first thing visitors notice. Renewing it keeps the building looking cared for.
Pricing washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.
