What the job involves on each surface
Welfare facilities

Retail & leisure sites
Customer toilets reflect on the business, and fresh sealant makes them look well kept.
Commercial sealant in Rooks Nest
Mouldy or split sealant in a commercial building causes more than a bad impression. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. If you have failed floor-level joints in accessible wet rooms and washroom sealant that looks dirty however often it’s cleaned, we can put it right.
Work in a small place like Rooks Nest is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Whatever the size of the job, you get the same 12-month guarantee.

When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Certifying fire stopping or building compliance
- Leaking pipework, valves or wastes (a plumber’s job)
- Extraction that is not working, which needs an electrician or ventilation contractor
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

What commercial sealant looks like in Rooks Nest
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings. Rooks Nest is part of Stevenage, one of the post-war new towns. Stevenage was planned with its own industrial and business areas, so there are offices, units and workplaces not far from home. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere.
Community buildings like Church of Saint Nicholas are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. For site and facilities teams at buildings such as Trotts Hill Primary and Nursery School, washroom and kitchen sealant can be programmed around term times or opening hours.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a single washroom, longer for a whole building. Somewhere like Rooks Nest needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Schedule work around occupancy
- Use mild cleaners on sealant, not bleach or abrasives
- Note the date each area was done
- Don’t leave a failed joint until the next refurbishment
Strong chemicals and scourers wear silicone out faster. A mild cleaner and a soft cloth is enough for the joints.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, so the fix is replacement.
When to call us in Rooks Nest
Larger buildings move, and stud walls move more than solid ones. The sealant between walls, trays and fittings absorbs that strain.
Look out for these signs:
- Rental bathrooms that need resealing between tenants
- Failed joints in office kitchens and tea points
- Leaks from showers into rooms or ceilings below
- Silicone laid over old silicone by a previous contractor
If you let a flat or house near Stevenage station, we can quote for one property or a whole portfolio of rentals.
Questions to ask before booking
- The length of the guarantee
- How hidden problems are handled
- Whether they’re fully insured
- Which colour the sealant will be
What happens if it’s left?
Before an inspection, audit or busy season, sealant is easy to overlook. Booking it in good time leaves room for the cure time before the visit. Older cottages and farmhouses around Rooks Nest can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.
