FAQs: Withdean

Can work in a care setting near Withdean go ahead while residents are there?

Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.

Is a hospital such as The Montefiore Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Is it OK to put new silicone on top of the old?

We always remove it. New silicone won’t stick to the old so a bead over the top fails quickly.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Washroom sealing for commercial buildings in Withdean

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’ll plan around them. The enquiries we see most involve complaints from staff, guests or users about tired washrooms and open joints along basins and vanity units, on kitchens and tea points, urinals and WCs and showers, trays and wet room floors. One point of contact handles commercial sealant work in Withdean from the first photos to the final walk-round, for single jobs and planned programmes alike.

A place of Withdean’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What affects the price in Withdean

What shapes the price:

  • Induction, permit and paperwork requirements
  • Working within restricted access windows
  • The size and state of each joint
  • Removal of failed or old sealant

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

To price the job accurately, we need to understand the site. Useful things to include:

  • Specification clauses that apply
  • When you need the work done
  • Rough lengths or quantities, or drawings if you have them
  • Clear photos of the problem areas

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or email us.

How the job changes by surface

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. We reseal the floor-to-wall junctions and around drains where sealant is used.

Healthcare and care settings

Assisted bathrooms and accessible toilets get heavy use so their sealant tends to fail sooner.

Commercial clients in Withdean

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, with each stage agreed with your site contact.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Withdean can form part of a wider programme across Brighton and Hove.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Water from plumbing, not from a joint
  • Hollow tiles or loose panels behind the joint
  • Failed tanking beneath a wet-room floor or behind tiles

If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think.

Surfaces we seal

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

When to bring in a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Redoing a failed joint typically costs more than getting it right at the outset, 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.

Busy facilities in and around Withdean

The sea is no more than about 2 miles from Withdean, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Washrooms used guest after guest wear their sanitary silicone faster, and the quieter months are the natural time to reseal. A good number of hotels sit less than 2 miles from Withdean. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available.

En suites at hotels like Preston Park Hotel, less than half a mile to the south of Withdean, are cleaned daily, which wears silicone over time. At a hospital like The Montefiore Hospital, which lies south of Withdean, patient and staff washrooms are best done in short phases agreed with the ward. Colleges such as Varndean College (to the east of Withdean) have toilets, changing rooms and catering kitchens that can be resealed around term dates.
