What the job involves on each surface
Kitchens and tea points
In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Where food contact is possible, we use a hygienic, food-safe sealant.
Basins and vanity tops
A failed joint along a vanity unit lets water into the carcass. Resealing early protects the unit.
Washroom sealing for commercial buildings in Letchworth Garden City
Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. We work on vanity units and basins, IPS panels and cubicles and showers, trays and wet room floors, and the usual reasons a site gets in touch are failed sealant behind washroom basins and failed joints along IPS and cubicle panels.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Work for main contractors and building owners
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Your questions answered
Will you plan work around the academic year at somewhere like North Hertfordshire College - Hitchin Campus?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you work in occupied care homes around Letchworth Garden City?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited and a Constructionline member.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How long does a job like this take?
It depends on the scope, but the work usually takes between a morning and a week or so, set by the number of rooms and the phasing you need. For bigger or phased jobs, we’ll set out a timescale with the quote.
Is it OK to put new silicone on top of the old?
The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.
What happens if it’s left?
Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Many buildings in towns like Letchworth Garden City have been extended or altered, and joints where old meets new tend to fail first. Renewing them before water gets in protects the fabric.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Doing it in-house
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. 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.

After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep a record of which washrooms need attention
- Avoid scourers and harsh descalers on silicone
- Respect the cure time before reopening each room
- Add sealant joints to planned maintenance checks
Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.
