Commercial sealant in St Leonards, done properly

Office kitchens, staff washrooms and welfare facilities need to be usable every working day. We can plan the work for early mornings or out of hours so the working day is disturbed as little as possible. Each area is handed back with its cure time. We work on student & care accommodation, office washrooms & kitchens and hotel bathrooms, and people most often call us about repeated reseals that don’t last and leaking joints in shower rooms and changing areas.

Community buildings, schools and small businesses around places like St Leonards have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.

You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

What happens on the day

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours per room, so whole buildings are phased. In a smaller place like St Leonards, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. The first visit is a look round the site to agree the scope.
  2. Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
  3. Areas are protected and the failed sealant removed.
  4. Joints are dried, then resealed and tooled neatly.
  5. We let your team know the cure time for every area.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Mention any parking rules near the property
  • For indoor joints, keep the area dry beforehand if you can

Signs you need commercial sealant in St Leonards

Commercial bathrooms get far more use than domestic ones, and they’re cleaned with strong products every day. That’s why sealant fails sooner.

The most common problems we see are:

  • Mouldy washroom sealant that staff and guests notice
  • Joints that need doing before an inspection or audit
  • Silicone laid over old silicone by a previous contractor
  • Mouldy bathrooms flagged at a tenancy check

If you look after a building such as St Ives Primary & Nursery School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Before you book anyone

  • Whether VAT is included
  • When the joint can take water or movement
  • What happens if they find a problem under the old sealant
  • How long the guarantee is

10 questions to ask before booking

Commercial buildings in St Leonards

Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

For buildings such as All Saints, its kitchen and washroom sealant needs looking after like anywhere else.

St Leonards is in Hampshire. Every kind of property in St Leonards can book us for commercial sealant, old or new, large or small. The work is guaranteed for a year. 683 places in Hampshire are on our list, from the larger towns to small villages. Our Southampton page covers work nearby, about 21 miles away.

Why deal with it now?

A quick bead over the old sealant might get a room back in use today, but silicone doesn’t bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. In a smaller place like St Leonards, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.

What affects the cost of commercial sealant

The quote reflects the job in front of us. We look at:

  • How many rooms, windows or areas are involved
  • Any working-time requirements on site
  • The number and length of the joints
  • Whether there’s mould to deal with

The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

What we need to know

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • If someone has resealed it before
  • A few pictures by email, if you can
  • The type of property
  • What’s wrong with the joints now

Want a quote for commercial sealant? Please ring 0345 464 0079 or email us with a few details. We’ll explain what we’d do and give you a clear quote before we start.

Surface by surface

Welfare facilities

Shower rooms in welfare blocks get heavy use and need sound joints. Anti-fungal sanitary silicone is used throughout, including accessible wet rooms.

Office washrooms & kitchens

Staff toilets, washrooms and kitchens get constant use, so the work can be arranged for quieter times. Basins, urinals, worktops and sinks are all resealed.

When it is not the sealant

In fairness, there are a few things sealant will not fix:

  • Poor ventilation that keeps bringing mould back
  • Damaged sanitaryware that needs replacing
  • Leaking pipework, valves or wastes (a plumber’s job)

If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Surfaces we seal

  • Retail & leisure sites
  • Office washrooms & kitchens
  • Rental portfolios
  • Hotel bathrooms
  • Welfare facilities
  • Student & care accommodation

Landlords, agents and businesses in St Leonards

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
