Keeping the joints in good condition

Aftercare is simple:

  • Act on lifting sealant before it leaks
  • Book larger programmes for quieter times of year
  • Log resealing so you know what’s due
  • Leave squeegees in busy showers

Ask staff to report splits or lifting sealant early. A small gap caught quickly is a short fix.

Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, so the fix is replacement.

What we do, step by step

When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before we start. Most jobs take a morning for a small washroom, and a planned programme for bigger sites. In Brondesbury Park, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  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. The joints are degreased, treated and left to dry.
  4. New sealant suited to each area is applied and tooled.
  5. We check every room and give its cure time for housekeeping.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Clear the area around the work
  • For business premises, tell us about site rules or sign-in

Why it’s worth doing now in Brondesbury Park

Patching the worst rooms as complaints come in is hard to manage. A planned programme works through every room, with less disruption and one clear quote. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Your questions about commercial sealant in Brondesbury Park

Do you work for landlords with property near Wembley Central station?

Do you work in hotels near Brondesbury Park?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.

What should I tell you?

The location, the problem and the rough size of the job. If you can, email a few photos.

Are you ARBOMaster approved?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

What does commercial sealant cost?

We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Is out-of-hours working possible?

Often, yes. Let us know when the building is quietest, and we’ll plan the work around them.

What we can’t put right

New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:

  • Tiles coming off the wall
  • Certifying fire stopping or building compliance
  • Cracked trays or baths rather than failed joints

If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

What the job involves on each surface

Retail & leisure sites

Changing areas and showers at leisure sites are wet all day, so anti-fungal sanitary silicone is the product we use.

Welfare facilities

Welfare facilities, shower rooms and changing areas need to stay usable. Work can be split into sections so some facilities stay open.

How we quote for commercial sealant

The quote reflects the job in front of us. We take into account:

  • The amount of work
  • Whether the work is at height
  • The product the joint needs
  • Any mould that needs treating

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Helping us quote

When you contact us, these details help:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the property is
  • If someone has resealed it before
  • Roughly how big the job is

There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To arrange one, ring 0345 464 0079 or email us.
