Commercial sealant in New Barnet, done properly

Commercial work is planned around the building, not the other way round. We can work room by room, floor by floor or in batches, and early starts or out-of-hours working can be arranged. Common call-outs are for repeated reseals that don’t last and water marks on ceilings under bathrooms, across office washrooms & kitchens, welfare facilities and rental portfolios.

In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in New Barnet, and room-by-room programmes can be planned where needed.

Big or small, it’s backed by our one-year guarantee.

FAQs for New Barnet

Do you work in hotels near New Barnet?

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 New Barnet station?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.

Which products 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.

Is out-of-hours working possible?

It can be arranged. The hours are agreed before work starts.

Where are you based?

We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

Can I choose the sealant colour?

Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures.

Can you send RAMS and insurance details for our site?

Tell us what your site asks contractors for. We’ll confirm what we can provide alongside the quote.

What happens if it’s left?

Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. Replacing it does. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in New Barnet.

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

When it is not the sealant

We’d rather tell you now than do work that won’t last, so these are the limits:

  • A broken extractor fan behind the mould problem
  • Tiles coming off the wall
  • Assessing what fire stopping a building needs

Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.

What happens on the day

You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a single washroom, longer for a whole building for a typical job. In New Barnet, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. Tell us the rooms, hours and site rules, and we’ll plan the programme.
  2. Tell us what paperwork your site needs, and we confirm what we can supply before we start.
  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. Rooms are handed back in order, each with its cure time.

What the job involves on each surface

Rental portfolios

Good sealant prevents leaks that cause bigger repairs, especially where you rarely see the bathroom yourself.

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.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. Our tips:

  • Log resealing so you know what’s due
  • Do not leave a failed joint until the next refurbishment
  • Leave squeegees in busy showers
  • Keep strong chemicals and scourers off the joints

Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.

It’s easier to plan a programme than to react to failures. We can fit the work around bookings, shifts and opening hours, instead of rooms closing without warning.

Commercial sealant around New Barnet

Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. London has hard water, so limescale builds up on sealant, grout and fittings.

Schools such as St Mary's CofE Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open. Community buildings like Holy Trinity Lyonsdown are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.

Do you need commercial sealant in New Barnet?

A hotel shower or office washroom is used many times a day, and they’re cleaned with strong products every day. That’s why sealant fails sooner.

Any of these means the joints need attention:

  • Leaks from showers into rooms or ceilings below
  • Joints that need doing before an inspection or audit
  • Split sealant around staff kitchen worktops and sinks
  • Mouldy bathrooms flagged at a tenancy check

New Barnet is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Before you book anyone

  • Whether they’re fully insured
  • What the cure time is
  • How the joint is cleaned and prepared
  • What happens if the job turns out different
