What the job involves on each surface

Rental portfolios

An empty property is easy to reseal, so the next tenant moves in to clean, sound joints.

Retail & leisure sites

Customer washrooms are part of the impression a business makes, and fresh sealant makes them look well kept.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

For landlords and businesses

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

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Common problems we fix in Whitstable

Shower trays and baths in busy buildings move more: different weights, constant use and daily cleaning. If a tray flexes, the sealant around it splits.

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

  • Silicone laid over old silicone by a previous contractor
  • Water marks on ceilings under bathrooms
  • Failed floor-level joints in accessible wet rooms
  • Too many rooms to reseal without closing the building

If you let a flat or house near Whitstable station, sealant work can be quoted for a single flat or a whole portfolio.

FAQs for Whitstable

Do you take on hotel work around Whitstable?

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

Do you work for landlords with property near Whitstable station?

Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.

Where is Mr Mastic based?

We work from Crawley. We cover Whitstable and the rest of Kent.

Is it OK to seal over old sealant?

No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Can you do several jobs on one visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit.

When can guests or staff use the shower again?

Plan for around 24 hours, or the cure time we give for that area. Planning the order of rooms keeps that downtime manageable.

Do you work in Whitstable?

Yes. We’re based in Crawley and work across South East England, London and Scotland, Whitstable included.

How much does commercial sealant cost in Whitstable?

We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Why act early in Whitstable

Sealing over the old bead can seem the fastest option, but silicone does not bond to silicone, so it lifts. One proper reseal beats several quick ones. Around Whitstable, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.

What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What happens on the day

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes anything from a few hours to several days, depending on the number of rooms, depending on how much there is to do. For a job in Whitstable, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.

  1. We start with a site walk to agree the rooms and the timing.
  2. Each area is protected and the old sealant cut out completely.
  3. We clean the joints, treat any mould and let them dry.
  4. We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
  5. We check every room and give its cure time for housekeeping.

Getting ready for the visit

  • Let us know about parking restrictions
  • Where the joints are inside, avoid wetting them before we arrive
  • Move anything stored near the joints

Workplaces and buildings in Whitstable

If you run a hotel, guest house or holiday let in a coastal place like Whitstable, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Whitstable has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

If you look after a church, hall or community building such as Church of St John (Methodist), any kitchen and washrooms need the same sealant care as any other building. For site and facilities teams at buildings such as The Whitstable School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
