About our washroom sealing in Ditton

Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on kitchens and tea points, accessible toilets and changing rooms and showers, trays and wet room floors, and the usual reasons a site gets in touch are black mould inside silicone joints that cleaning can’t shift and failed joints along IPS and cubicle panels. Whether you call it commercial sealant work, mastic application or joint sealing, in Ditton it comes down to the same thing: the right product in a properly prepared joint.

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

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. If others near Ditton need work, visits can be combined. A fixed quote is given before anything starts.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Getting the site ready

  • Make sure the joints can be reached
  • Let us know about inductions and permits

FAQs: Ditton

Can you work around term dates at a campus such as Royal Holloway University?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Will our hotel in Ditton need to close for the work?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

How soon can a washroom be used after resealing?

The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so there are always rooms open.

Do you phase washroom resealing?

We phase it so there are always facilities open. We work through the building a room or section at a time. Tell us your site hours and access windows and we will plan around them.

Which silicone is right for commercial washrooms?

Sanitary silicone with anti-mould additives in the majority of cases. We use neutral-cure versions on stone, some metals and near mirrors.

What affects the price in Ditton

To price the job, we consider:

  • How much existing material needs removing
  • Working within restricted access windows
  • Joint width, depth and condition
  • Which sealant the job calls for

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • When you need the work done
  • The postcode of the building
  • Asbestos survey details if the building is older
  • Specification clauses that apply

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or send details through our quote form if you’d rather talk the job through.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Clear standing water from shower floors where possible
  • Don’t leave an open joint at a basin or tray
  • Inspect washroom sealant regularly
  • Avoid scourers and harsh descalers on silicone

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Replacing it early keeps the job to a reseal.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Common problems we fix in Ditton

Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We check for that first and tell you if another trade is needed.

If one of these sounds familiar, it’s time for a closer look:

  • Sealant laid over old silicone and now peeling
  • Failed sealant in a tea point or staff kitchen
  • Complaints from staff, guests or users about tired washrooms
  • Gaps where vanity tops meet the wall

In a centre such as Slough Retail Park, 2.8 miles to the north-west of Ditton, public washrooms are resealed a block of facilities at a time.

Before you book anyone

  • Will RAMS and insurance details be available?
  • Proof of insurance
  • Their plan for phasing and protecting the area
  • Are they CHAS accredited or on Constructionline?
