Washroom sealing across Lamberhurst Quarter

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Aftercare for building managers

Regular inspection catches problems early. Specifically:

  • Include joints in routine washroom inspections
  • Respect the cure time before reopening each room
  • Keep extract fans working and vents clear
  • Report split joints at trays and basins early

If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

About our washroom sealing in Lamberhurst Quarter

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. There is public liability insurance behind every job. Our workmanship is guaranteed for 12 months. We work on urinals and WCs, showers, trays and wet room floors and kitchens and tea points, and the failures we are asked to look at most are stained or open joints at kitchen sinks and worktops and failed joints along IPS and cubicle panels. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Lamberhurst Quarter is the same: the right product in a properly prepared joint.

Halls and community buildings near places like Lamberhurst Quarter are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Common problems we fix in Lamberhurst Quarter

Washrooms are warm, damp and full of organic residue, and sealant joints trap all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

Things that usually lead to an enquiry:

  • Stained sealant around pans and urinals
  • Washrooms that look worn because of the sealant
  • Black mould inside silicone joints that cleaning can’t shift
  • Kitchen worktop joints that can’t be kept clean

In any commercial washroom in or near Lamberhurst Quarter, mouldy sealant is cut out rather than cleaned, and anti-mould sanitary silicone goes on clean, dry joints.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • How joint depth will be controlled
  • How they’ll work around occupants
  • Their public liability cover

Choosing a commercial sealant contractor

Doing it in-house

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Your questions answered

Will the toilets in our Lamberhurst Quarter building be out of use?

Typically only some of them, for a short time. We work in phases so other facilities stay open. We’ll tell you the curing time for the product before we start.

Is a hospital such as Pembury Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email us. Include photographs or drawings if you have them.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Which silicone is right for commercial washrooms?

It depends on the joint. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Is old silicone taken out first?

The failed bead is always removed. New silicone won’t stick to the old so a bead over the top fails quickly.

Surface by surface

Kitchens and tea points

Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sealed joints leave no gaps for food and dirt.

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and look unhygienic.
