Washroom sealing for Kelvedon Hatch sites

Washroom sealing in Kelvedon Hatch

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 are dealing with stained or open joints at kitchen sinks and worktops and split or peeling sealant at shower trays, we can help, on accessible toilets and changing rooms, vanity units and basins and IPS panels and cubicles alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Kelvedon Hatch, preparation and product choice get the time they need.

Smaller places such as Kelvedon Hatch still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Kelvedon Hatch: questions and answers

Is Kelvedon Hatch too far out for you?

Not at all. Kelvedon Hatch is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do we have to close all our washrooms in Kelvedon Hatch for resealing?

Rarely all at once: work is phased so some facilities are always available. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Is there a guarantee on the work?

Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Can washrooms stay open while you work?

Just the room being resealed is out of use. Rooms go back into use once the sealant has cured, then we move on.

Do you use special sealant for toilets and showers?

It depends on the joint. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

Is old silicone taken out first?

We strip every bit of the failed bead and wipe away the residue before resealing. That’s what makes the new joint last.

How do we ask for a quote?

You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email the details over. Include photos or drawings if you have them.

What we can’t put right

Being straight saves everyone time. Fresh joints won’t solve:

  • Swollen or delaminated boards behind panels or vanity tops
  • Leaks through tanking or membranes below the finishes
  • Hollow tiles or loose panels behind the joint

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

Surfaces we seal

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

Different surfaces, different methods

IPS and cubicle panels

Swollen or delaminated boards need replacing, and any we come across will be pointed out.

Changing rooms and gyms

Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we’ll plan around them.

Washroom sealing around Kelvedon Hatch: how the place shapes the job

Central London is about 20 miles from Kelvedon Hatch. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.

For a school such as Kelvedon Hatch Community Primary School, washroom and kitchen sealant can be renewed around term dates. Where you’re responsible for a hall attached to a building such as New Church of St Nicholas, its kitchen and toilets need sealant that stays cleanable.

Kelvedon Hatch is about 3 miles north-west of Brentwood, in Essex.

Site staff or a sealant specialist?

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.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Kelvedon Hatch, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work

Work for main contractors and building owners

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, and each stage is agreed with your contact.

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.

What we’re called out for in Kelvedon Hatch

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting and they discolour and fail early.

Typical triggers for a call:

  • Sealant laid over old silicone and now peeling
  • Failed joints along IPS and cubicle panels
  • Users noticing mouldy joints
  • Kitchen worktop joints that can’t be kept clean

Healthcare estates like Brentwood Community Hospital, 3.3 miles to the south-east of Kelvedon Hatch, expect contractors to follow their permits and cleaning rules in every washroom.

Questions to ask before you book

  • How joint depth will be controlled
  • What the guarantee covers, and for how long
  • How they’ll work around occupants
  • Health and safety accreditation such as CHAS
