Trusted commercial sealant in Cowesfield Gate

Commercial sealant in Cowesfield Gate, done properly

Staff facilities cannot be out of action for long. We can plan the work for early mornings or out of hours to keep disruption down. You are told when each area can be used again. If you are dealing with tired sealant in let properties and leaks from showers into rooms or ceilings below, we can help.

In a village or hamlet like Cowesfield Gate, 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.

There’s a 12-month guarantee on every job.

What we can’t put right

In fairness, there are a few things sealant won’t fix:

  • Failed tanking or loose tiles behind the sealant
  • Assessing what fire stopping a building needs
  • Poor ventilation that keeps bringing mould back

If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

Where we work in Cowesfield Gate

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

Work for landlords, hotels and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

How to look after the new joints

Simple care keeps the joints in good condition. We recommend:

  • Tell cleaning staff when each room can be used
  • Keep a record of which rooms were resealed and when
  • Check the joints during routine room inspections
  • Put a squeegee in each shower

Ask staff to report splits or lifting sealant early. Catching one split early can save a leak later.

Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Dealing with the joint early stops that spread.

What affects the cost of commercial sealant

We quote each job individually. These are the things that affect it:

  • When we can work, for business premises
  • Whether there’s mould to deal with
  • Which sealant suits the joint
  • The number of rooms or windows

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Helping us quote

Photos by email are helpful but not essential. Try to tell us:

  • Any previous sealing or DIY work
  • What’s wrong with the joints now
  • Whether it’s a home or a business
  • How many joints, rooms or windows are involved

To get a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before any work starts.

What happens on the day

Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from a few hours to several days, depending on the number of rooms. Somewhere as small as Cowesfield Gate, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Tell us the rooms, hours and site rules, and we will plan the programme.
  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. Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
  5. Each finished area is checked with you and given a cure time.

Before we arrive

  • Tell us if parking is tricky
  • Mention any leaks or damp you’ve noticed
  • Mention any sign-in or site rules at work premises

Related advice

Can I do it myself?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

When to call us in Cowesfield Gate

Internal washrooms and en suites without a window rely entirely on extraction, and where extraction is poor, damp hangs around. Mould then takes hold in the silicone.

Most people get in touch after spotting something like this:

  • Whole floors of tired en suites
  • Black, stained silicone in guest bathrooms
  • Failed floor-level joints in accessible wet rooms
  • Failed joints in office kitchens and tea points
