Washroom sealing for Lamb Corner sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Washroom sealing for commercial buildings in Lamb Corner

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Only replacement gets rid of it for good. If you have stained or open joints at kitchen sinks and worktops and users noticing mouldy joints, we can put it right, on kitchens and tea points, vanity units and basins and showers, trays and wet room floors alike. For commercial sealant work in Lamb Corner, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

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

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common questions from Lamb Corner clients

Would you work within a site like Severalls Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Is Lamb Corner too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

Can washrooms stay open while you work?

Just the room being resealed is out of use. Each room reopens after the sealant’s cure time, then we move on.

Does the weather affect the work?

Outside, 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.

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: its movement, its surfaces and what it has to cope with.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Water from plumbing, not from a joint
  • Condensation from failed extract fans
  • Vanity carcasses that have swollen

Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly before you book.

Central London is about 55 miles from Lamb Corner. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available. There are several hotels within about 2 miles of Lamb Corner. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. The work can go floor by floor, agreed with housekeeping.

Student showers at universities like University of Essex (to the south of Lamb Corner) see more use than most, and their silicone shows it. Clinical washrooms at sites like Severalls Hospital, 4 miles to the south-west of Lamb Corner, are scheduled with the ward so the room is out of use for as little time as possible. Pupil toilets at schools like Dedham Church of England Voluntary Controlled Primary School take heavy daily use, and the holidays give the window to reseal.

What affects the price in Lamb Corner

Each job is priced on its own details. The main factors are:

  • Travel to remote or island sites
  • How much existing material needs removing
  • Phasing around occupants
  • Specialist products, such as fire-rated or hygienic sealants

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • The product your specification calls for
  • Where the site is, with the postcode
  • Access details, including height
  • Your programme or deadline

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or phone 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Our process

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Rural sites near Lamb Corner may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Getting the site ready

  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

Related advice

Leave it or put it right?

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Around Lamb Corner, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
