Washroom sealing across Cross in Hand

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If others near Cross in Hand need work, visits can be combined. You will have a fixed quote before work starts.

  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. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

What we need from you

  • Send any specification or drawings in advance
  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use

Getting a fixed quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

How we handle washroom sealing in Cross in Hand

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Every resealed washroom carries our 12-month guarantee. We work on showers, trays and wet room floors, vanity units and basins and urinals and WCs, and the failures we’re asked to look at most are stained sealant around pans and urinals and mould spotting along silicone joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Cross in Hand is the same: the right product in a properly prepared joint.

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

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Keeping Cross in Hand washrooms open while we work

Cross in Hand lies roughly 39 miles out from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available.

At a school such as Cross-in-Hand Church of England Primary School, changing rooms and kitchens need cleanable joints as much as the toilets. For an occupier at a site such as Station Road Industrial Estate, which lies east of Cross in Hand, the canteen and welfare facilities need cleanable joints as much as any office. Clinical washrooms at sites like Uckfield Community Hospital (4.9 miles west of Cross in Hand) are scheduled with the ward so the room is out of use for as little time as possible.

Cross in Hand is about 5 miles east of Uckfield, in East Sussex. We send applicators to Cross in Hand for washrooms and wet areas, handled exactly as we handle every other area. Our East Sussex coverage takes in 308 places. Our Brighton page has more on work in that area.

We cover the TN21 postcode districts for washrooms and wet areas. If your site is on Fir Grove Road, Windmill Place and Dads Hill or close by, we can quote for washrooms and wet areas. If your building is just outside Cross in Hand, we cover Roser's Cross (1 mile south-west), Waldron (1 mile south-west), Heathfield (2 miles east), Sandy Cross (2 miles south-east) and Lions Green (2 miles south). A short drive away, we cover Eastbourne (13 miles south), Bexhill-on-Sea (14 miles south-east), Seaford (14 miles south), Lewes (11 miles south-west), Hailsham (8 miles south) and Crowborough (6 miles north).

Why act early in Cross in Hand

Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. One visit to deal with every failing joint makes more sense than several trips to a place like Cross in Hand, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What you get with us

  • Products installed to the manufacturer’s instructions
  • Standard and matched colours in many product ranges

Questions we’re asked in Cross in Hand

Will the toilets in our Cross in Hand building be out of use?

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

Can you work on a hospital site such as Uckfield Community Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

How long before the toilets can reopen?

That varies with the sealant and the room temperature. You will get a reopening time for each area before we leave it.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

What’s the quickest route to a quote?

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

Keeping the joints sound

A few simple habits keep the new joints working:

  • Respect the cure time before reopening each room
  • Note failing joints building by building
  • Clear standing water from shower floors where possible
  • 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. Beyond that, regular checks keep small problems small.

A few failed joints can be resealed with hardly any disruption. Left, it tends to become a building-wide job and more closures to manage.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Cost factors for washrooms and wet areas

What shapes the price:

  • The product specified
  • Working within restricted access windows
  • How accessible the joints are
  • Quantities, in metres or numbers

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Any dates the work must fit around
  • Any specification or named product
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or use the quote form.

Different surfaces, different methods

Changing rooms and gyms

Gym and leisure changing rooms see showers running most of the day so sealant there works very hard. Anti-mould sanitary silicone is the standard choice.

Urinals and WC pans

Pan and urinal joints face constant cleaning and splashing. Once they discolour or split, they hold odours and make the room look neglected.
