Commercial sealant in Newton Stewart

How we handle commercial sealant in Newton Stewart

In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, applied by ARBOMaster approved applicators. We work on hotel bathrooms, student & care accommodation and office washrooms & kitchens, and people most often call us about too many rooms to reseal without closing the building and split sealant around staff kitchen worktops and sinks.

Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.

Every job comes with a 12-month guarantee, wherever you are in Dumfries and Galloway.

Commercial sealant in Newton Stewart: local notes

Around Newton Stewart, as everywhere, commercial sealant is only as good as the preparation behind it.

When it is not the sealant

It helps to know what we cannot do too:

  • Certifying fire stopping or building compliance
  • Water damage behind the tiles that needs a tiler or builder
  • Poor ventilation that keeps bringing mould back

Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Why act early in Newton Stewart

A leaking shower in a hotel room or flat above can damage the ceiling below. That means a second room out of use and a repair to pay for. Resealing first is the smaller job. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

Why book with us

  • We’re fully insured
  • An ARBOMaster approved applicator
  • Colour picked to suit the job
  • Colour agreed with you before any work starts

When to call us in Newton Stewart

Quick fixes come back quickly. New silicone over old, joints that weren’t dried, or an unsuitable product all lead to the same thing: another reseal before long.

Most people get in touch after spotting something like this:

  • Washrooms that need sorting before an inspection
  • Leaking joints in shower rooms and changing areas
  • Silicone laid over old silicone by a previous contractor
  • Mouldy bathrooms flagged at a tenancy check

For site and facilities teams at buildings such as Douglas Ewart High School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Questions to ask before booking

  • Whether you can choose the colour
  • How hidden problems are handled
  • How much experience the applicator has
  • What insurance they hold

Work for landlords, hotels and businesses

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

If you manage several properties in or around Newton Stewart, jobs at different addresses can be quoted together. Send us the addresses and the work at each.

What we do, step by step

We keep the work tidy and contained to the area we’re working on. The job usually takes a few hours for a single washroom, longer for a whole building, and we tell you how long to leave it before we go. Outside jobs in Newton Stewart need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.

  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. Rooms are handed back in order, each with its cure time.

How to prepare

  • Keep pets and children clear of the area while we work
  • Tell us if parking is tricky
  • For indoor joints, keep the area dry beforehand if you can

How to get a quote

Every job is quoted individually, so start by telling us what you need. Just drop us a line at info@mrmastic.co.uk with the details and send photos if you have them.

Can I do it myself?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
