Signs you need commercial sealant in Dumfries

Plenty of commercial bathrooms have no window at all, and where extraction is poor, damp hangs around. Mould then takes hold in the silicone.

Most people get in touch when they notice one of these:

  • Mouldy bathrooms flagged at a tenancy check
  • Large numbers of bathrooms needing the same work
  • Failed floor-level joints in accessible wet rooms
  • Leaks from showers into rooms or ceilings below

How to choose a mastic man

Work for landlords, hotels and businesses

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

Can I do it myself?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What sealant work can’t fix

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

  • Poor ventilation that keeps bringing mould back
  • Assessing what fire stopping a building needs
  • Tiles coming off the wall

If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

Surfaces we seal

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

The process

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours per area, with larger sites planned over several visits from start to finish. A visit in Dumfries needs three things planned: access, parking and where the work is. Outside work depends on the weather, as sealant needs a dry surface.

  1. We walk the site with you and agree the rooms, the order and the hours.
  2. Each area is protected and the old sealant cut out completely.
  3. Joints are cleaned, treated for mould and dried.
  4. We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
  5. Rooms are checked and returned with a cure time so staff know when to use them.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints

What happens if it’s left?

In a building with rooms above rooms, a failed shower seal can soon show on a ceiling below. Then two rooms are out of action, not one. Resealing first is the smaller job. For landlords in Dumfries, damp and leaks can fall under the Repairing Standard. Sorting failed joints early is easier than dealing with a tenant’s complaint.

What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
