Washroom sealing in Howes, done properly

In a busy washroom, the sealant typically gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you have split or peeling sealant at shower trays and discoloured joints around urinals and WC pans, we can put it right, on showers, trays and wet room floors, urinals and WCs and kitchens and tea points alike. Looking for mastic applicators who cover Howes? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Hotels and holiday accommodation in rural Scotland have busy and quiet seasons, and resealing washrooms in the quieter months keeps rooms available when they’re needed.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Keeping Howes washrooms open while we work

Howes lies within about 2 miles of the sea, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Washrooms used guest after guest wear their sanitary silicone faster, so we plan the work for quieter weeks where possible. The east of Scotland, where Howes is, gets less rain than the west. Even so, a washroom that doesn’t dry out between uses will see mould get into its sealant.

On a healthcare site such as Annan Hospital, which lies east of Howes, washroom work starts with the infection-control team’s sign-off. Where you are responsible for a hall attached to a building such as Old Parish Church, its kitchen and toilets need sealant that stays cleanable.

Howes is about 14 miles east of Dumfries, in Dumfries and Galloway. Businesses, contractors and managing agents in Howes can call on us for washrooms and wet areas, as part of our coverage of Dumfries and Galloway. Across Dumfries and Galloway, 139 places are covered, including Howes. For work in that direction, see our Edinburgh page (66 miles or so).

Cost factors for washrooms and wet areas

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • The size and state of each joint
  • Access and working height
  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

What we need to price the job

A few photographs plus some basic facts will normally do. It helps to include:

  • The product your specification calls for
  • How the joints are reached, and at what height
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email us.

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Where we can, we combine work around Howes with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Preparing the site

  • Flag any permit to work we will need
  • Warn occupants and staff about the work
  • Have the specification and drawings to hand

When to call us in Howes

Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We check for that first and say if it needs a plumber or another trade.

It’s worth sending us details if you spot any of the following:

  • Complaints from staff, guests or users about tired washrooms
  • Shower tray joints that have opened up
  • Sealant laid over old silicone and now peeling
  • Black mould inside silicone joints that cleaning can’t shift

For a school such as Annan Academy, washroom and kitchen sealant can be renewed around term dates.

Before you book anyone

  • The terms of the workmanship guarantee
  • Who will actually carry out the work
  • Will RAMS and insurance details be available?
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

Commercial clients in Howes

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Howes can sit alongside others in a wider programme across Dumfries and Galloway.

Common questions from Howes clients

Is Howes too far out for you?

Not at all. Howes is within our area. Every Scottish council area is within our area. Good photographs up front let us bring everything on the first visit.

Do you take on work at healthcare sites like Annan Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you clean the mould off instead of resealing?

Not for long. The mould is inside the silicone so cleaning only lightens it for a while. Replacement is the lasting fix.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Do you use special sealant for toilets and showers?

It depends on the joint. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Swollen or delaminated boards behind panels or vanity tops
  • Condensation from failed extract fans

If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think before you book.

Where we work in Howes

  • IPS panels and cubicles
  • Urinals and WCs
  • Showers, trays and wet room floors
  • Accessible toilets and changing rooms
  • Kitchens and tea points
  • Vanity units and basins

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Respect the cure time before reopening each room
  • Clear standing water from shower floors where possible
  • Avoid scourers and harsh descalers on silicone
  • Act on the first split you see at a shower tray

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life over time.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.
