Washroom sealing across Woodlands

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

Building owners, agents and FMs in Woodlands

Building owners and managing agents use us on everything from one building to a spread of sites around Woodlands. Several sites can go on one quote, so there’s one set of paperwork to deal with.

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.

Washroom sealing in Woodlands, done properly

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Every resealed washroom carries our 12-month guarantee. The enquiries we see most involve users noticing mouldy joints and a new bead over an old one coming away, across kitchens and tea points, IPS panels and cubicles and showers, trays and wet room floors. Facilities teams, main contractors and managing agents in Woodlands tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural businesses near smaller places such as Woodlands, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Our process

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. For work around Woodlands, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Before we start on site

  • Let building users know which areas are affected
  • Agree which areas must stay open
  • For older buildings, check the asbestos register before work

Washroom sealing around Woodlands: what changes locally

There are four care or nursing homes within about 2 miles of Woodlands. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Work is agreed with the manager, around residents’ routines.

Healthcare estates like Tatchbury Mount Hospital, 2.1 miles to the north of Woodlands, expect contractors to follow their permits and cleaning rules in every washroom. Colleges such as Totton College, 2 miles to the north-east of Woodlands, have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Woodlands is about 2 miles south-west of Totton, in Hampshire. We cover Woodlands and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 723 places across Hampshire fall within our area, including Woodlands.

When to call us in Woodlands

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They don’t stand up to constant water, and they stain, crack or wash out.

These are often picked up first by site or facilities staff:

  • Sealant laid over old silicone and now peeling
  • Split or peeling sealant at shower trays
  • Stained sealant around pans and urinals
  • Panel joints letting water behind

Toilets at places like Totton Shopping Centre (to the north-east of Woodlands) are cleaned constantly, so silicone needs to be sound and smooth.

Before you book anyone

  • Which product they’ll use, and why it suits the joint
  • How the existing material will be dealt with
  • Their public liability cover
  • What the guarantee covers, and for how long

Our contractor checklist

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • How much there is to seal
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first
  • Specialist products, such as fire-rated or hygienic sealants

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • Clear photos of the problem areas
  • Rough lengths or quantities, or drawings if you have them
  • When you need the work done
  • The type of building and who uses it

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

After the work

For the best life from the joints:

  • Make sure washroom ventilation is running
  • Tell us about infection-control or permit rules before we quote
  • Don’t leave trays and floors sitting wet
  • Note failing joints building by building

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Swollen or delaminated boards behind panels or vanity tops
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Loose panels, vanity units or tiles, which need fixing first

If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think before you book.

Surfaces we seal

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

Woodlands: questions and answers

Is a hospital such as Tatchbury Mount Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is Woodlands too far out for you?

Not at all. Woodlands is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

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.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee backed by public liability insurance.
