About our commercial sealant in Newtown Common

Guest bathrooms are cleaned every day and used by different people every night, so sealant wears out faster than it would at home. We work through rooms in batches, so only a few are out of use at once, with a cure time for each room so housekeeping know when to release it. We work on student & care accommodation, retail & leisure sites and office washrooms & kitchens, and people most often call us about leaks from showers into rooms or ceilings below and failed floor-level joints in accessible wet rooms.

In a village or hamlet like Newtown Common, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

A 12-month guarantee comes as standard, so you’re covered after we have gone.

What happens on the day

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours per room, so whole buildings are phased. Somewhere as small as Newtown Common, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We agree a programme with you: which rooms, in what order, at what times.
  2. We go through your site’s paperwork needs, such as RAMS, before work begins.
  3. Old sealant is cut out room by room and joints cleaned and treated.
  4. We reseal with the right product for each joint.
  5. Each finished area is checked with you and given a cure time.

Before we arrive

  • Let us know about parking restrictions
  • Keep children and pets away from the work area
  • Clear the area around the work

Advice

Common problems we fix in Newtown Common

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:

  • Leaks from showers into rooms or ceilings below
  • Joints that need doing before an inspection or audit
  • Rental bathrooms that need resealing between tenants
  • Split sealant around staff kitchen worktops and sinks

For landlords with property near Newbury station, we can quote for one property or a whole portfolio of rentals.

What to look for in a quote

  • What guarantee comes with the work
  • What preparation is included
  • How much experience the applicator has
  • How the colour is chosen

Choosing a sealant specialist

What affects the cost of commercial sealant

Jobs vary more than people expect. The main factors:

  • Whether there’s mould to deal with
  • Access and height
  • The product the joint needs
  • How much old sealant there is and how hard it is to remove

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Helping us quote

You don’t need to know the technical terms. Just tell us:

  • If it’s domestic, commercial or a hotel
  • Photos by email, if that is easy
  • How we’d reach the joints
  • The rough size of the job

Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job.

Your questions about commercial sealant in Newtown Common

Do you work for landlords with property near Newbury station?

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

Can you do commercial sealant in Newtown Common?

Yes, Newtown Common is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.

Is there any odour?

Sometimes, a little. It fades as the sealant cures.

Can the hotel stay open while you work?

Yes. Rooms are done a few at a time, keeping most rooms available. Each room comes back with its cure time for housekeeping.

Should I try DIY first?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Can new sealant go over the old?

No, because it fails. We remove every bit of old sealant first.

Does someone need to be in?

We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.

Does commercial work come with a guarantee?

Yes. We’re fully insured, ARBOMaster approved and give a 12-month guarantee on every job.

Aftercare tips

Good habits help new joints last longer. A few tips:

  • Book larger programmes for quieter times of year
  • Include the silicone on your room checklists
  • Pass on the cure time to whoever cleans the rooms
  • Check extract fans are actually running

Keep the extraction running and maintained. In internal bathrooms, a weak or broken fan lets moisture linger, and mould comes back faster without it.

A room that can’t be let or used is lost income. Catching faults early means they can be put right in a short window, before they become leaks that take the room out of use.

Workplaces and buildings in Newtown Common

Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

For buildings such as Church of St Mary and St John the Baptist, halls and community kitchens see heavy use, and their sealant shows it. If you look after a building such as Horris Hill School, busy washrooms and kitchens can be resealed in phases so they stay open.

When it isn’t the sealant

Before booking, it’s worth knowing the limits too:

  • Faulty shower valves and leaking traps
  • Cracked trays or baths rather than failed joints
  • Poor ventilation that keeps bringing mould back

Why deal with it now?

Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. If something else is wrong, we will say so. In a small place like Newtown Common, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.
