Washroom sealing for Alfold Crossways sites

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

Washroom sealing for commercial buildings in Alfold Crossways

Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. If you are dealing with a new bead over an old one coming away and stained sealant around pans and urinals, we can put it right. Most enquiries from Alfold Crossways start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Rural businesses near smaller places such as Alfold Crossways, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we’ll plan around them.

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.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes between a morning and a week or so, set by the number of rooms and the phasing you need, and our waste is bagged and taken away as we go. Smaller jobs around Alfold Crossways can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Send your site hours and access windows
  • Tell us which areas need to stay in use

Related advice

Do you need washroom sealing in Alfold Crossways?

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Look out for the following:

  • Mould spotting along silicone joints
  • A new bead over an old one coming away
  • Open joints along basins and vanity units
  • Washrooms that look worn because of the sealant

Welfare facilities in units on estates such as Littlemead Industrial Estate (2.6 miles north of Alfold Crossways) have showers, toilets and kitchens with sealant that works hard.

How to choose a sealant contractor

Why it’s worth doing now in Alfold Crossways

Sealing on top of old silicone saves nothing. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. Converted and older buildings near places like Alfold Crossways tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Your questions answered

What paperwork can you provide for a job in Alfold Crossways?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Is Alfold Crossways off your patch?

No. Places such as Alfold Crossways are covered as much as the big towns. 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 we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Can you clean the mould off instead of resealing?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

Can you handle several sites?

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

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Is old silicone taken out first?

The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.

Owners, agents and contractors

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Alfold Crossways is about 33 miles from central London, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, which is why the work is phased.

Halls linked to places like Church of St Nicholas host groups all week, which is hard on kitchen and toilet sealant.

After the work

A few simple habits keep the new joints working:

  • Avoid scourers and harsh descalers on silicone
  • Keep washrooms out of use until we say the sealant has cured
  • Act on the first split you see at a shower tray
  • Make sure washroom ventilation is running

Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

Doing it in-house

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
