Washroom sealing for commercial buildings in Aston

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. Most enquiries involve failed sealant behind washroom basins and split or peeling sealant at shower trays, across showers, trays and wet room floors, IPS panels and cubicles and urinals and WCs. One point of contact handles commercial sealant work in Aston from the first photographs to the final walk-round, whether it’s one building or several.

Community buildings around smaller places like Aston have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes half a day to a day per washroom, depending on the number of fittings, and our waste is bagged and taken away as we go. For work around Aston, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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 give you a reopening time for every room.

What we need from you

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Share your working hours and any access restrictions

Advice

Owners, agents and contractors

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Looking after the joints

After handover, a little attention goes a long way:

  • Note failing joints building by building
  • Tell us about infection-control or permit rules before we quote
  • Squeegee showers and trays after busy periods
  • Add sealant joints to planned maintenance checks

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

Questions about Aston

Is Aston off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as Longworth Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is it possible to just clean mouldy silicone?

Typically not. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacement is the lasting fix.

How do you choose the sealant?

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

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact.

Sanitary sealant for Aston buildings

At about 62 miles from central London, Aston is within reach of the capital, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available.

Where you’re responsible for a hall attached to a building such as Church of St James, its kitchen and toilets need sealant that stays cleanable. For buildings on a site such as Bampton Business Centre North, which lies south-west of Aston, washrooms and tea points can be resealed in phases through the working week.

Why it’s worth doing now in Aston

A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Around Aston, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Why appoint us

  • Constructionline member for supplier checks
  • Commercial sealant work since 2005

Do you need washroom sealing in Aston?

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

Most enquiries start with something like this:

  • Gaps where vanity tops meet the wall
  • Sealant laid over old silicone and now peeling
  • Sealant lifting along a tray edge
  • Urinal joints that look unhygienic

Clinical washrooms at sites like Longworth Hospital, 5.7 miles to the south-west of Aston, are scheduled with the ward so the room is out of use for as little time as possible.

Comparing quotes

  • Whether their applicators hold CSCS cards
  • What level of public liability insurance do they hold?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
