Signs you need commercial sealant in Shephall

In an accessible wet room, water spreads across the floor every use, so the joints at floor level are under water often. Any split there can let water through quickly.

It’s worth asking for a quote if you see:

  • Large numbers of bathrooms needing the same work
  • Washrooms that need sorting before an inspection
  • Silicone laid over old silicone by a previous contractor
  • Water marks on ceilings under bathrooms

Rented homes near Stevenage station change hands often, and we can quote for one property or a whole portfolio of rentals.

What your quote should include

  • When the joint can take water or movement
  • Whether they seal over old material or remove it
  • Which sealant they’ll use, and why
  • How long the guarantee is

10 questions to ask before booking

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The process

We keep the work tidy and contained to the joints we are treating. The job normally takes a few hours per area, with larger sites planned over several visits, and we tell you how long to leave it before we go. For a job in Shephall, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We walk the site with you and agree the rooms, the order and the hours.
  2. Room by room, we protect the area and remove all the old sealant.
  3. We clean the joints, treat any mould and let them dry.
  4. New sealant suited to each area is applied and tooled.
  5. We check every room and give its cure time for housekeeping.

Getting ready for the visit

  • On commercial sites, let us know about site rules
  • Clear the area around the work
  • Let us know if you’ve seen damp or leaks

Commercial buildings in Shephall

Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings. Shephall 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. Each has washrooms, kitchens and fire-rated joints to keep in order.

If you look after a building such as Peartree Spring Primary School, washroom and kitchen sealant can be programmed around term times or opening hours. If you look after a church, hall or community building such as Church of Saint Mary, its kitchen and washroom sealant needs looking after like anywhere else.

Shephall is about 1 mile south of Stevenage, in Hertfordshire. Jobs in Shephall get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee.

Retail & leisure sites

Gym and leisure changing rooms take heavy use and plenty of water, so joints are sealed with anti-fungal sanitary silicone.

Hotel bathrooms

In a hotel, every bathroom is used and cleaned daily, so we use anti-fungal sanitary silicone and finish joints smooth for easy cleaning.

What sealant work can’t fix

We will always be straight with you, so here’s what sealant can’t fix:

  • Extraction that isn’t working, which needs an electrician or ventilation contractor
  • Water damage behind the tiles that needs a tiler or builder
  • Assessing what fire stopping a building needs

If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Where we work in Shephall

For landlords and businesses

We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.

We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Add sealant to your planned maintenance checks
  • Keep strong chemicals and scourers off the joints
  • Note the date each area was done
  • Check extract fans are actually running

Ask staff to report splits or lifting sealant early. A small gap caught quickly is a short fix.

Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.
