Washroom sealing near Chartway Street

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

On site: what to expect

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. If others near Chartway Street need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.

Getting the site ready

  • Arrange parking or a loading space
  • Share the asbestos register for older buildings
  • Tell us what induction or permit system the site runs

Washroom sealing in Chartway Street

From one staff toilet in Chartway Street to washrooms across a whole estate, the route is the same: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. The enquiries we see most involve sealant laid over old silicone and now peeling and gaps where vanity tops meet the wall, across urinals and WCs, IPS panels and cubicles and showers, trays and wet room floors. Whoever orders the work in Chartway Street, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Farm shops, cafés and venues in converted rural buildings around places like Chartway Street have busy toilets and kitchens. We plan the work around bookings and opening times.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Busy facilities in and around Chartway Street

At about 36 miles from central London, Chartway Street is within reach of the capital, within the office belt around the capital. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time.

On a healthcare site such as KIMS hospital, 5.1 miles north-west of Chartway Street, washroom work starts with the infection-control team’s sign-off. Student showers at universities like Canterbury Christ Church University, 4.2 miles to the north-east of Chartway Street, see more use than most, and their silicone shows it. Where you’re responsible for a hall attached to a building such as St Peter's and St Paul's Church, its kitchen and toilets need sealant that stays cleanable.

What the job involves on each surface

Healthcare and care settings

In healthcare, sealed joints are part of infection control. Your infection-control and estates rules are followed as well as site permits.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Where food contact is possible, we use a hygienic, food-safe sealant.

Questions about Chartway Street

Is a hospital such as KIMS hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Is Chartway Street too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Do you phase washroom resealing?

We phase it so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

How much does the work cost?

Each job is quoted on its own details. For yours, call the office on 01277 525 020 or use the quote form.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

For managing agents and facilities managers

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. We can agree access arrangements and keyholder contacts beforehand.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • The size and state of each joint
  • How much existing material needs removing
  • Induction, permit and paperwork requirements
  • Working within restricted access windows

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Approximate linear metres or a joint schedule
  • Specification clauses that apply
  • Your programme or deadline
  • Access details, including height

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Should maintenance staff do it?

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.

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.

Why deal with it now?

Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. A full reseal deals with it and cleaners stop fighting a losing battle. Around Chartway Street, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
