How we handle commercial sealant in South Mundham

For a rental portfolio, resealing between tenants keeps bathrooms and kitchens presentable. Several addresses can be quoted together. If you are dealing with water marks on ceilings under bathrooms and leaking joints in shower rooms and changing areas, we can put it right, whatever the surface.

In a village or hamlet like South Mundham, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

South Mundham: your questions answered

Can you help a landlord with a rental near Chichester station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.

Is South Mundham in your area for commercial sealant?

Yes, South Mundham is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.

How long do rooms need to be out of use?

Normally after around 24 hours. Each room is handed back with the cure time for the product used.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Do you take on large, multi-room jobs?

Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, so only part of the building is affected at once.

Can you send RAMS and insurance details for our site?

Let us know your site’s requirements. We’ll confirm what we can supply before work is booked.

Do you offer different sealant colours?

Most of the time, yes. We will tell you which colours the right product comes in and agree one before work begins.

Is out-of-hours working possible?

In many cases. Tell us your opening hours and quiet times, and we’ll plan the work around them.

Aftercare tips

Good habits help new joints last longer. Our tips:

  • Pass on the cure time to whoever cleans the rooms
  • Use mild cleaners on sealant, not bleach or abrasives
  • Get split or lifting joints looked at early
  • Put a squeegee in each shower

A squeegee in each shower is a simple help: less water sits on the joints between uses.

Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.

Workplaces and buildings in South Mundham

If you run a hotel, guest house or holiday let in a coastal place like South Mundham, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Letting a property close to Chichester station? Then we can quote for one property or a whole portfolio of rentals. Schools such as North Mundham Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Different surfaces, different methods

Retail & leisure sites

Customer toilets reflect on the business, and clean, neat sealant makes them look cared for.

Student & care accommodation

Halls and care homes often have many near-identical bathrooms. A room-by-room programme keeps the job efficient.

Honest limits

We won’t take on work that won’t last, so these are the limits:

  • Assessing what fire stopping a building needs
  • Leaking pipework, valves or wastes (a plumber’s job)
  • Poor ventilation that keeps bringing mould back

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

Where we work in South Mundham

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

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.

What we are called out for in South Mundham

Internal washrooms and en suites without a window rely entirely on extraction, and where extraction is poor, damp hangs around. That’s when black mould sets into the bead.

Keep an eye out for any of the following:

  • Rental bathrooms that need resealing between tenants
  • Tired sealant ahead of a health and safety audit
  • Mouldy washroom sealant that staff and guests notice
  • Failed floor-level joints in accessible wet rooms

Community buildings like The Parish Church of St Stephen are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

What to look for in a quote

  • When the joint can take water or movement
  • What happens if the job turns out different
  • Is VAT in the price?
  • What insurance they hold

How to choose a mastic man

Why deal with it now?

Patching the worst rooms as complaints come in is hard to manage. A planned programme works through every room, keeping disruption down and costs clear. In a small place like South Mundham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

Why book with us

  • White, clear, grey or another colour, product permitting
  • Sanitary silicone with an anti-fungal additive in wet areas
  • We agree the colour with you first
  • Neat joints and a tidy finish

The process

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a morning for a small washroom, and a planned programme for bigger sites. In a small place like South Mundham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. Rooms are checked and returned with a cure time so staff know when to use them.

Getting ready for the visit

  • Let us know about parking restrictions
  • Tell us about any water getting in
  • Try not to wet indoor joints just before the visit
