Common questions from Poets Estate clients

Can you work in a care home near Poets Estate with residents in?

Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we will work to them.

Is Poets Estate off your patch?

Not at all. Poets Estate is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Do you do washroom sealing in healthcare settings?

Yes. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Washroom sealing for commercial buildings in Poets Estate

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them. The products and the method are chosen for how heavily each space is used. If you have sealant laid over old silicone and now peeling and discoloured joints around urinals and WC pans, we can help, whatever the surface. For commercial sealant work in Poets Estate, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

A place of Poets Estate’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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Aftercare for building managers

Regular inspection catches problems early. Specifically:

  • Keep washrooms out of use until we say the sealant has cured
  • Brief cleaning staff to treat joints gently
  • Add sealant joints to planned maintenance checks
  • Clear standing water from shower floors where possible

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Quoting for work in Poets Estate

A fixed quote reflects the actual work. It takes account of:

  • The product specified
  • How much there is to seal
  • The size and state of each joint
  • Travel to remote or island sites

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What to include in your enquiry

To price the job accurately, we need to understand the site. Send us:

  • The type of building and who uses it
  • Rough lengths or quantities, or drawings if you have them
  • Photos of the joints, close up and from further back
  • The product your specification calls for

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Why deal with it now?

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • CHAS accredited contractor
  • Matching to RAL references, product permitting
  • Colours confirmed for the specified product
  • Joints cleaned back to sound surfaces

See what affects the cost and how we’re accredited.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Vanity carcasses that have swollen
  • Water escaping beneath the floor rather than through a joint
  • A dripping waste or valve behind a panel

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Surfaces we seal

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

Keeping Poets Estate washrooms open while we work

Poets Estate lies roughly 32 miles out from central London. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open. Poets Estate has a good number of hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later.

At a hospital like Pinehill Hospital, which lies west of Poets Estate, patient and staff washrooms are best done in short phases agreed with the ward. Customer toilets and staff facilities at retail sites such as Letchworth Gateway Retail Park (2.8 miles north-east of Poets Estate) need sealant that stays clean under heavy use. For a hotel such as The Lord Lister Hotel, 1 mile to the west of Poets Estate, resealing en suites a few rooms at a time keeps the rest available.

Poets Estate is about 1 mile east of Hitchin, in Hertfordshire.

When to bring in a specialist

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.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Several jobs near Poets Estate can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

What we need from you

  • Arrange parking or a loading space
  • Let building users know which areas are affected
  • Send asbestos survey details if the building is pre-2000
