Common questions from Cuddesdon clients

Is a hospital such as Slade Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Does a hotel in Cuddesdon need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Can washrooms stay open while you work?

We phase it so users always have somewhere to go. We work through the building a room or section at a time around your site hours and access windows.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Is it OK to put new silicone on top of the old?

We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.

Washroom sealing for commercial buildings in Cuddesdon

Whether it’s a single toilet block in Cuddesdon or a programme across several buildings, the route is the same: send details, get a fixed quote, we seal, guaranteed. A few photos and a count of fittings are enough for a quick quote, or we can arrange a visit. We work on kitchens and tea points, urinals and WCs and vanity units and basins, and what we are called in for most is split or peeling sealant at shower trays and urinal joints that look unhygienic. A single leaking joint is often how a building in Cuddesdon first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Rural businesses near smaller places such as Cuddesdon, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.

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.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Inspect washroom sealant regularly
  • Keep a record of which washrooms need attention
  • Clear standing water from shower floors where possible
  • Clean sealant with gentle products and a soft cloth

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

From enquiry to sign-off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. If others near Cuddesdon need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Getting the site ready

  • Let building users know which areas are affected
  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work

Toilets, showers and kitchens around Cuddesdon

Cuddesdon is about 47 miles from central London. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available. There are several hotels within about 2 miles of Cuddesdon. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available.

Church halls and community buildings, such as those at Church of All Saints, have kitchens and toilets used by many groups, and their sanitary sealant works hard. In a centre such as Oxford Retail Park, which lies west of Cuddesdon, public washrooms are resealed a block of facilities at a time. If you manage an office at a site such as The Boundary Business Park (0.9 miles west of Cuddesdon), the washrooms and tea points can be done a floor at a time.

How the quote is worked out

These are the things that shape the price:

  • How much there is to seal
  • How accessible the joints are
  • Which sealant the job calls for
  • Working within restricted access windows

A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Call for a quote.

Details that help us quote

However big the job, the same details help:

  • The asbestos register, for older buildings
  • How the joints are reached, and at what height
  • The type of building and who uses it
  • The postcode of the building

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Commercial clients in Cuddesdon

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, with each stage agreed with your site contact.

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Hollow tiles or loose panels behind the joint
  • Water from plumbing, not from a joint
  • Vanity carcasses that have swollen

If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

What we seal

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

What the job involves on each surface

Urinals and WC pans

We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked, so the sealant has to take that movement. Loose panels are flagged before any sealant goes on.
