About our washroom sealing in Totteridge

In healthcare and care settings, sealing is part of keeping surfaces cleanable. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Any records you need are confirmed with the quote. If you have sealant laid over old silicone and now peeling and urinal joints that look unhygienic, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Totteridge is the same: the right product in a properly prepared joint.

A place of Totteridge’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Your questions answered

Does a hotel in Totteridge need to shut while its sealant is renewed?

Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we’ll plan around them.

Can you work on a hospital site such as Wycombe General Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Which silicone is right for commercial washrooms?

Sanitary silicone with anti-mould additives for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.

Will cleaning remove black mould from sealant?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Common problems we fix in Totteridge

Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.

What tends to prompt an enquiry:

  • Failed sealant in a tea point or staff kitchen
  • Resealing that didn’t last because the old bead stayed
  • Washrooms that look worn because of the sealant
  • Stained sealant around pans and urinals

Hotels such as Red Lion Hotel (to the west of Totteridge) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

What your quote should include

  • How joint depth will be controlled
  • How the joint faces will be prepared and primed
  • Will CSCS-carded applicators be on site?
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Swollen or delaminated boards behind panels or vanity tops
  • Condensation from failed extract fans

If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

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

Keeping Totteridge washrooms open while we work

There are a number of hotels within about 2 miles of Totteridge. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. Rooms are done in turn so most stay available. At about 29 miles from central London, Totteridge is within reach of the capital. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.

On a healthcare site such as Wycombe General Hospital (1.3 miles west of Totteridge), washroom work starts with the infection-control team’s sign-off. Units at estates like The Wye Industrial Estate (0.7 miles south of Totteridge) have welfare blocks whose showers and toilets see shift after shift.

Totteridge is about 1 mile east of High Wycombe, in Buckinghamshire. We send applicators to Totteridge for washrooms and wet areas. Totteridge is one of 308 places in Buckinghamshire on our list for washrooms and wet areas. For work in that direction, see our Reading page (17 miles or so).

We take on washrooms and wet areas across the HP13 and HP11 postcode area, whatever the building. If your site is on Hunt Road, Perth Road and Elora Road or close by, we can quote for washrooms and wet areas. If your building is just outside Totteridge, we cover Micklefield (1 mile east), Terriers (1 mile north-west), Wycombe Marsh (1 mile south), High Wycombe (1 mile west) and Tylers Green (1 mile north-east). Bigger towns within reach include Aylesbury (13 miles north), Chesham (7 miles north-east), Marlow (5 miles south-west), Amersham (6 miles north-east), Beaconsfield (4 miles south-east) and Chalfont St Peter (7 miles east).

Related advice

Leave it or put it right?

Cleaning mouldy sealant only masks it, but the mould is rooted in the silicone and comes back. A full reseal deals with it and cleaners stop fighting a losing battle. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
