About our washroom sealing in Aldermaston Wharf

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. We work on urinals and WCs, showers, trays and wet room floors and IPS panels and cubicles, and the failures we’re asked to look at most are sealant stained black around basins and showers and urinal joints that look unhygienic. Looking for mastic applicators who cover Aldermaston Wharf? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

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

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

When to call us in Aldermaston Wharf

Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed, and shower trays shift under foot. If the joint wasn’t laid to take that movement, it tears or peels away.

What tends to prompt an enquiry:

  • Urinal joints that look unhygienic
  • A new bead over an old one coming away
  • Mould spotting along silicone joints
  • Washrooms that look worn because of the sealant

Where you’re responsible for a hall attached to a building such as Church of St John the Baptist, its kitchen and toilets need sealant that stays cleanable.

Before you book anyone

  • Which product they’ll use, and why it suits the joint
  • Whether old or failed sealant will be cut out, not overlaid
  • Their approach to joint depth and backing
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Your questions answered

Do we have to close all our washrooms in Aldermaston Wharf for resealing?

Typically only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Must a hotel around Aldermaston Wharf close while you work?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you reseal washrooms in healthcare buildings?

We do. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.

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.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Work for main contractors and building owners

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.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

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.

Sanitary sealant for Aldermaston Wharf buildings

Central London is about 45 miles from Aldermaston Wharf. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time. Aldermaston Wharf has several hotels close by, all within 2 miles. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available.

En suites at hotels like Comfort Hotel (to the north-east of Aldermaston Wharf) are cleaned daily, which wears silicone over time. If you manage an office at a site such as Fronds Park Business Park, 0.8 miles south-west of Aldermaston Wharf, the washrooms and tea points can be done a floor at a time.

Why deal with it now?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Halls, stores and units around places like Aldermaston Wharf may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you are ready.

Cost factors for washrooms and wet areas

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Whether the work must be split into stages
  • How much existing material needs removing
  • Location, for remote and island sites
  • The total length or number of joints

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Details that help us quote

Diagnosis starts before we arrive. Let us know:

  • Specification clauses that apply
  • Photos of the joints, close up and from further back
  • Where the site is, with the postcode
  • How the joints are reached, and at what height

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Smaller jobs around Aldermaston Wharf can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  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.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Send your site hours and access windows
  • For older buildings, check the asbestos register before work
