Common problems we fix in West Reading

Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We check for that first and say if it needs a plumber or another trade.

Clients normally get in touch after noticing one or more of the following:

  • Complaints from staff, guests or users about tired washrooms
  • Black mould inside silicone joints that cleaning can’t shift
  • Gaps where vanity tops meet the wall
  • Split or peeling sealant at shower trays

Customer toilets and staff facilities at retail sites such as Reading Retail Park, 1 mile to the north-west of West Reading, need sealant that stays clean under heavy use.

Our contractor checklist

Washroom sealing in West Reading

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. Most enquiries involve resealing that didn’t last because the old bead stayed and failed sealant behind washroom basins, on urinals and WCs, vanity units and basins and accessible toilets and changing rooms. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in West Reading is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Pub and restaurant kitchens around smaller places like West Reading work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Common questions from West Reading clients

Is West Reading off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Will you plan work around the academic year at somewhere like University of Reading?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can you reseal washrooms in healthcare buildings?

Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in West Reading, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work
  • Arrange parking or a loading space

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Condensation from failed extract fans
  • Hollow tiles or loose panels behind the joint

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.

Where we work in West Reading

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

Busy facilities in and around West Reading

A 2-mile radius around West Reading takes in plenty of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest. Central London is about 39 miles from West Reading. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.

Toilets at colleges like Reading College (1.7 miles east of West Reading) take heavy use from students and staff alike. For a site such as Spire Dunedin Hospital, less than half a mile south-east of West Reading, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Commercial clients in West Reading

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Aftercare for building managers

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Don’t leave trays and floors sitting wet
  • Keep extract fans working and vents clear
  • Add sealant joints to planned maintenance checks
  • Avoid scourers and harsh descalers on silicone

Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Site staff or a sealant specialist?

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.

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