Washroom sealing in Aston Clinton, done properly

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. Most enquiries involve resealing that didn’t last because the old bead stayed and black mould inside silicone joints that cleaning can’t shift, across showers, trays and wet room floors, vanity units and basins and urinals and WCs. Most enquiries from Aston Clinton start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Jobs in a smaller place such as Aston Clinton are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. A list and photos let us quote and plan so it’s done in one visit where possible.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sets the cost

Before we quote, we look at:

  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • The site’s rules and procedures

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

What we need to price the job

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

  • The site address and postcode
  • How the joints are reached, and at what height
  • The product your specification calls for
  • The asbestos register, for older buildings

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or use the quote form.

What the job involves on each surface

IPS and cubicle panels

A panel that has already swollen won’t be fixed by sealant and we will point out any we see.

Kitchens and tea points

Worktop, sink and splashback joints in tea points take water and food. Sealed joints leave no gaps for food and dirt.

Common problems we fix in Aston Clinton

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Things that usually lead to an enquiry:

  • Mould spotting along silicone joints
  • Failed sealant behind washroom basins
  • Failed sealant in a tea point or staff kitchen
  • Users noticing mouldy joints

For a site such as Stoke Mandeville Hospital, 3.2 miles west of Aston Clinton, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

What to look for in a quote

  • What the guarantee covers, and for how long
  • How they’ll work around occupants
  • The named product and why it was chosen
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

Looking after the joints

To get the most from the new sealant:

  • Add sealant joints to planned maintenance checks
  • Leave signs up until the cure time is over
  • Don’t leave trays and floors sitting wet
  • Clean sealant with gentle products and a soft cloth

Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface and give mould a start.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Your questions answered

Will our hotel in Aston Clinton need to close for the work?

In most cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.

Can work at a site such as University Campus Aylesbury Vale fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Can you clean the mould off instead of resealing?

Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Can you reseal washrooms in healthcare buildings?

We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.

Do you need to remove the old sealant?

We always remove it. New silicone won’t stick to the old, so sealing over it soon peels.

How a job runs

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Work in places the size of Aston Clinton is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached
  • Point out any areas we must not close
