Different surfaces, different methods
Showers and trays
Shower joints in hotels, gyms and workplaces work hard. Each bead is stripped, the joint dried and new sealant laid.
Healthcare and care settings
Assisted bathrooms and accessible toilets get heavy use, so their joints often need renewing sooner.

Advice
Washroom sealing around Aldenham: points for this area
Central London is about 16 miles from Aldenham, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, so we work a block of facilities at a time. Several hotels sit less than 2 miles from Aldenham. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The work can go floor by floor, agreed with housekeeping.
Toilets at colleges like West Herts College, 2.4 miles to the south-west of Aldenham, take heavy use from students and staff alike. Welfare facilities in units on estates such as Otters Pool Way Industrial Estate, 0.7 miles to the south-west of Aldenham, have showers, toilets and kitchens with sealant that works hard. For centre management at a site such as Waterfields Shopping Park, 2.1 miles south-west of Aldenham, washroom work is planned around footfall.

What happens if it’s left?
Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. Older rural buildings around Aldenham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Pricing washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

What else we do in Aldenham
Owners, agents and contractors
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Loose panels, vanity units or tiles, which need fixing first
- Mould caused by poor ventilation, which will return until the extract is fixed
- Water escaping beneath the floor rather than through a joint
If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Common questions from Aldenham clients
Could you schedule work at a campus like West Herts College for the vacation?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you work on a hospital site such as Watford General Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Is it OK to put new silicone on top of the old?
The failed bead is always removed. New silicone won’t stick to the old so a bead over the top fails quickly.
Is there a guarantee on the work?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
How long before the toilets can reopen?
Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.
Can washrooms stay open while you work?
The work is phased so users always have somewhere to go. We work through the building a room or section at a time around your site hours and access windows.
What sets the cost
These are the things that shape the price:
- How much there is to seal
- Backing rod, priming and other preparation
- The product specified
- Travel to remote or island sites
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Good information means a firmer quote. When you get in touch, include:
- Whether the building will be occupied during the work
- The product your specification calls for
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
For a fixed quote, phone 01277 525 020 or email the details over with the site address and an outline of the work. You can also send details through our quote form.
