How we handle commercial sealant in Portsmouth

Guest bathrooms are cleaned every day and used by different people every night, so sealant wears out faster than it would at home. Rooms are resealed 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. Common call-outs are for shower leaks reaching the floor below and leaking joints in shower rooms and changing areas, across retail & leisure sites, rental portfolios and student & care accommodation.

A place the size of Portsmouth has offices, shops, hotels and schools, each with its own washrooms, kitchens and fire-rated joints to look after. Our work covers washroom and kitchen sealant as well as fire-rated sealant, fitted to the product’s tested details.

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

For landlords and businesses

Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

What commercial sealant looks like in Portsmouth

For seaside hotels, guest houses and holiday lets around Portsmouth, 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, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Community buildings like St Wilfrid are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it. Schools such as Manor Infant School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Rented homes near Fratton station change hands often, and several rental properties can be resealed on one programme.

How it works

There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours per room, so whole buildings are phased in most cases. Where a business in Portsmouth needs to stay open, out-of-hours working can be arranged, while home visits are arranged within our normal working hours, Monday to Saturday.

  1. First we visit and agree the scope, the sequence and the working hours.
  2. Every area is sheeted and the old silicone stripped out.
  3. We clean the joints, treat any mould and let them dry.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
  5. Rooms are checked and returned with a cure time so staff know when to use them.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Where the joints are inside, avoid wetting them before we arrive
  • Keep children and pets away from the work area

How to get a quote

Asking for a quote is easy: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we will take it from there.

Advice

What affects the quote in Portsmouth

We quote each job individually. This is what makes a difference:

  • Any mould that needs treating
  • How many rooms, windows or areas are involved
  • Working hours on commercial sites
  • The amount of work

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

  • The rough size of the job
  • Access, such as stairs, a lift or height
  • Where the property is
  • What the problem is, such as mould, gaps, leaks or cracking

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or send us an email.

Honest limits

To be straight with you, some problems need a different trade:

  • Faulty shower valves and leaking traps
  • Assessing what fire stopping a building needs
  • Tiles coming off the wall

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Joints and surfaces we work on

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

DIY versus a professional finish

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Surface by surface

Retail & leisure sites

Retail and leisure sites have washrooms, kitchens and changing areas with sealant to maintain. Work can be arranged outside opening hours where that is possible.

Student & care accommodation

Many accommodation blocks have rows of similar en suites. A room-by-room programme keeps the job efficient.

Portsmouth: your questions answered

Can you do commercial sealant in Portsmouth?

Yes, Portsmouth 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, and we’ll give you a clear quote.

Do you work for landlords with property near Fratton station?

Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.

Can I choose the sealant colour?

We help you choose a colour that suits. The product needed can limit the range.

Where are you based?

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

What sealant do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

How long do rooms need to be out of use?

Most areas can be used after around 24 hours. Each room is handed back with the cure time for the product used.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Why it’s worth doing now in Portsmouth

Sealant work is quick by the room: it takes as long as the scope needs, from one welfare room to a full building. Each area is then left to cure for the time we give you, so planning the order matters more than the hours on site. In a large rental market like Portsmouth, tired sealant leads to tenant complaints about mould, damp and leaks. It’s simpler to sort between tenants than in the middle of a let.

Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
