Washroom sealing in Aldworth

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Our workmanship is guaranteed for 12 months. The enquiries we see most involve urinal joints that look unhygienic and sealant lifting along a tray edge, on kitchens and tea points, vanity units and basins and urinals and WCs. For commercial sealant work in Aldworth, you deal with one contact from quote to sign-off, whether it’s one building or several.

Community buildings around smaller places like Aldworth have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Doing it in-house

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Why it’s worth doing now in Aldworth

Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. Halls, stores and units around places like Aldworth may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Aldworth: questions and answers

Is a smaller place like Aldworth outside your area?

No. Places such as Aldworth are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will all the washrooms in our Aldworth building be closed at once?

Rarely all at once: work is phased so some facilities are always available. We will tell you the curing time for the product before we start.

Do you work in hospitals, clinics and care homes?

We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Is there a guarantee on the work?

Every job carries our 12-month guarantee. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.

How much does the work cost?

Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or use the quote form.

Central London is about 48 miles from Aldworth. Washrooms in commuter-belt offices take constant weekday traffic, which is why the work is phased.

Where you’re responsible for a hall attached to a building such as St Mary's church, its kitchen and toilets need sealant that stays cleanable.

Aldworth is about 7 miles south of Didcot, in West Berkshire. Any commercial site in Aldworth is covered. Aldworth is one of 140 places we cover in West Berkshire for washrooms and wet areas. We also cover Reading, some 11 miles away.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Signs you need washroom sealing in Aldworth

Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead, so it soon lets go.

Things that normally lead to an enquiry:

  • Stained or open joints at kitchen sinks and worktops
  • Sealant stained black around basins and showers
  • Failed sealant behind washroom basins
  • Split or peeling sealant at shower trays

Schools such as The Downs School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • Is the sealant right for the movement and the substrate?
  • How the existing material will be dealt with
  • How they’ll work around occupants

Our contractor checklist

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Aldworth can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.

What we need from you

  • Share the asbestos register for older buildings
  • Tell staff and tenants when we’ll be in
  • Share your working hours and any access restrictions

Getting a fixed quote

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email a schedule or drawings.

What the job involves on each surface

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and make the room look neglected.

Wet-room floors and floor-to-wall joints

Wet floors are common in accessible showers and changing rooms, so their perimeter joints get close attention.
