Washroom sealing for businesses in Pottersheath

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

About our washroom sealing in Pottersheath

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. There is public liability insurance behind every job. Our workmanship is guaranteed for 12 months. If you have failed joints along IPS and cubicle panels and sealant laid over old silicone and now peeling, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Pottersheath it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Pottersheath still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

FAQs: Pottersheath

Is Pottersheath off your patch?

Not at all. Pottersheath is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as Queen Elizabeth II Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

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 work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it.

Can washrooms stay open while you work?

The work is phased so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Which silicone is right for commercial washrooms?

Each area gets the grade that suits it. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

What the job involves on each surface

IPS and cubicle panels

IPS panels and cubicle systems have joints at the wall, the floor and the worktop. Those joints protect the boards behind from water.

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.

Why it’s worth doing now in Pottersheath

When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. For buildings around smaller places like Pottersheath, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What you get with us

  • Over 20 years of commercial sealing
  • Products installed to the manufacturer’s instructions

Sanitary sealant for Pottersheath buildings

At about 25 miles from central London, Pottersheath is within reach of the capital. Office washrooms on business parks see heavy weekday use, which is why the work is phased.

For a hall at a building such as Church of St Michael and All Angels, resealing the kitchen and toilets can be fitted between bookings. For a hotel such as The Wellington Inn Hotel, which lies south of Pottersheath, resealing en suites a few rooms at a time keeps the rest available. For a site such as Queen Elizabeth II Hospital, which lies south of Pottersheath, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Cost factors for washrooms and wet areas

These are the things that shape the price:

  • Quantities, in metres or numbers
  • Phasing around occupants
  • Distance, for remote addresses
  • Backing rod, priming and other preparation

A quote for washrooms and wet areas depends on how many there are, their condition and the access. Call for a quote.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • Anything awkward about access or site hours
  • The postcode of the building
  • Any dates the work must fit around
  • Whether the building will be occupied during the work

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email the details over.

On site: what to expect

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Preparing the site
