Jobs vary more than people expect. The main factors:
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- The size of the job
- Any working-time requirements on site
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Aftercare tips
Looking after new joints is easy:
- Report broken fans quickly
- Encourage users to squeegee shower walls
- Give housekeeping the cure time for every room
- Use mild cleaners on sealant, not bleach or abrasives
We give a cure time for every area we finish, which is generally around 24 hours. Pass it on to housekeeping or cleaners so nobody showers or cleans the joint too early.
Rooms out of use cost a hotel or landlord money. Catching faults early means they can be put right in a short window, before they become leaks that take the room out of use.
Shoreham-by-Sea: your questions answered
I let a flat near Shoreham-By-Sea station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is Shoreham-by-Sea in your area for commercial sealant?
Yes, Shoreham-by-Sea is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
How soon can a room be used after resealing?

Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Can you reseal hotel rooms while we stay open?
Yes. We agree a batch of rooms for each visit, working around check-out and check-in where possible.
Commercial buildings in Shoreham-by-Sea
For seaside hotels, guest houses and holiday lets around Shoreham-by-Sea, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
If you look after a church, hall or community building such as St Mary de Haura Church, any kitchen and washrooms need the same sealant care as any other building. If you let a flat or house near Shoreham-By-Sea station, sealant work can be quoted for a single flat or a whole portfolio.

Why it’s worth doing now in Shoreham-by-Sea
A leaking shower in a hotel room or flat above can damage the ceiling below. That means a second room out of use and a repair to pay for. Resealing first is the smaller job. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What we can’t put right
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Water coming from plumbing rather than sealant
- Water damage behind the tiles that needs a tiler or builder
- Certifying fire stopping or building compliance
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

- Hotel bathrooms

- Welfare facilities
- Rental portfolios
What we are called out for in Shoreham-by-Sea
Plenty of commercial bathrooms have no window at all, and where extraction is poor, damp hangs around. Mould then takes hold in the silicone.
The problems people generally mention when they call are:
- Washrooms that need sorting before an inspection
- Sealant failing again soon after quick repairs
- Split sealant around staff kitchen worktops and sinks
- Failed floor-level joints in accessible wet rooms
Schools such as Buckingham Park Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.
