Washroom sealing in Chackmore

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

Different surfaces, different methods

Kitchens and tea points

Worktop, sink and splashback joints in tea points take water and food. Sound joints keep those surfaces easy to clean.

IPS and cubicle panels

A panel that has already swollen won’t be fixed by sealant, and any we come across will be pointed out.

Washroom sealing in Chackmore

Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on accessible toilets and changing rooms, showers, trays and wet room floors and urinals and WCs, and the usual reasons a site gets in touch are open joints along basins and vanity units and washrooms that look worn because of the sealant. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Chackmore is the same: the right product in a properly prepared joint.

Farm shops, cafés and venues in converted rural buildings around places like Chackmore have busy toilets and kitchens. We plan the work around bookings and opening times.

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 bring in a specialist

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 a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When to call us in Chackmore

A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead so it peels away quickly.

Common reasons buildings call us in:

  • A new bead over an old one coming away
  • Washrooms that look worn because of the sealant
  • Mould spotting along silicone joints
  • Failed sealant behind washroom basins

On an industrial estate such as Moreton Road Industrial Estate, 1 mile to the south-east of Chackmore, staff toilets, showers and canteens are where sanitary sealant takes the most wear.

What to look for in a quote

  • Who will actually carry out the work
  • How the joint faces will be prepared and primed
  • Are they CHAS accredited or on Constructionline?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Questions to ask before you appoint anyone

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking half a day to a day per washroom, depending on the number of fittings. Smaller jobs around Chackmore can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Have the specification and drawings to hand
  • Agree which areas must stay open
  • For older buildings, check the asbestos register before work

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Leave signs up until the cure time is over
  • Inspect washroom sealant regularly
  • Don’t leave trays and floors sitting wet
  • Make sure washroom ventilation is running

Ventilation is half the battle. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
