Need washroom sealing in Over Wallop?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Swollen or delaminated boards behind panels or vanity tops
  • A dripping waste or valve behind a panel

If you are not sure, just phone 01277 525 020 or email us and we will give you a straight answer.

Surfaces we seal

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

How we handle washroom sealing in Over Wallop

Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. If you are dealing with split or peeling sealant at shower trays and kitchen worktop joints that can’t be kept clean, we can put it right. Looking for mastic applicators who cover Over Wallop? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

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

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to call us in Over Wallop

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

It’s worth sending us details if you spot any of the following:

  • Users noticing mouldy joints
  • A new bead over an old one coming away
  • Stained or open joints at kitchen sinks and worktops
  • Split or peeling sealant at shower trays

At a hotel such as Fifehead Manor Hotel, which lies south-east of Over Wallop, the quieter weeks are the time to reseal bathrooms.

What your quote should include

  • What the guarantee covers, and for how long
  • Proof of insurance
  • How joint depth will be controlled
  • Will RAMS and insurance details be available?

Choosing a commercial sealant contractor

Schools such as Wallop Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays. Church halls and community buildings, such as those at Church of St Peter, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Over Wallop: questions and answers

What site paperwork comes with a job in Over Wallop?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Is Over Wallop too far out for you?

Not at all. Over Wallop is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

Can you reseal washrooms in healthcare buildings?

Yes, healthcare and care settings are part of our work. Tell us what records you need and we will confirm with the quote.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

How long before the toilets can reopen?

Cure times vary by product and temperature. You will get a reopening time for each area before we leave it.

Aftercare for building managers

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Keep washrooms out of use until we say the sealant has cured
  • Brief cleaning staff to treat joints gently
  • Mention any site permits or estates rules at quote stage
  • Add sealant joints to planned maintenance checks

Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs in and around smaller places like Over Wallop are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • Share the asbestos register for older buildings
  • Let building users know which areas are affected
  • Point out any areas we must not close
