Washroom sealing in Great Lea Common, done properly

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Every resealed washroom carries our 12-month guarantee. We work on accessible toilets and changing rooms, showers, trays and wet room floors and urinals and WCs, and the failures we’re asked to look at most are washrooms that look worn because of the sealant and failed joints along IPS and cubicle panels. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Great Lea Common it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Rural businesses near smaller places such as Great Lea Common, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we will plan around them.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email a schedule or drawings and we will come back to it.

Honest limits

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

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

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly.

Surfaces we seal

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

What happens if it’s left?

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. For buildings around smaller places like Great Lea Common, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why appoint us

  • RAL and finish matching where the product range allows
  • Workmanship guaranteed for 12 months
  • A fixed quote before work starts
  • One phone line for London, the South East and Scotland

What we’re called out for in Great Lea Common

Panels and vanity units move slightly in use, and shower trays shift under foot. If the joint wasn’t laid to take that movement, it tears or peels away.

Any of the following is a good reason to get the joints checked over:

  • Resealing that didn’t last because the old bead stayed
  • Open joints at the base of cubicle panels
  • Sealant stained black around basins and showers
  • Failed sealant in a tea point or staff kitchen

Halls of residence and teaching buildings at universities such as University of Reading - Whiteknights Campus, 2.5 miles to the north-east of Great Lea Common, are easiest to reseal during vacations.

What your quote should include

  • Health and safety accreditation such as CHAS
  • What level of public liability insurance do they hold?
  • How the joint faces will be prepared and primed
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Sanitary sealant for Great Lea Common buildings

At about 39 miles from central London, Great Lea Common is within reach of the capital. Office washrooms on business parks see heavy weekday use, and resealing in phases keeps facilities available. The area within 2 miles of Great Lea Common holds a number of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. Rooms are done in turn so most stay available.

Church halls and community buildings, such as those at St Paul's Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard. For a hotel such as voco Reading Hotel, which lies north of Great Lea Common, resealing en suites a few rooms at a time keeps the rest available.

Cost factors for washrooms and wet areas

Your fixed quote is built from the real scope. It takes account of:

  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages
  • Specialist products, such as fire-rated or hygienic sealants

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you are ready.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Whether an asbestos survey exists
  • Any dates the work must fit around
  • The type of building and who uses it
  • Drawings or a marked-up plan, if available

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.

Questions about Great Lea Common

Can you take on a job at a hospital such as Berkshire Independent Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can work at a site such as University of Reading - Whiteknights Campus fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Do you need to remove the old sealant?

The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How long does a job like this take?

It depends on the scope, though a typical visit usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Diagnose, treat, sign off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Smaller jobs around Great Lea Common can be grouped with others nearby. You’ll have a fixed quote before work starts.

  2. The fixed quote sets out the rooms, the products and the phasing.

  4. Joints are degreased and dried.

Different surfaces, different methods

Showers and trays

Shower joints in hotels, gyms and workplaces work hard. Every joint is stripped, degreased, dried and given a new bead.

Basins and vanity tops

Vanity tops and basins are splashed all day, so the wall joint and bowl surrounds tend to fail before anything else. We remove the old bead and lay a fresh one of sanitary silicone.
