Need washroom sealing in Northway?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle washroom sealing in Northway

In healthcare and care settings, sealing is part of keeping surfaces cleanable. We work to your organisation’s estates and infection-control requirements and any site permits. Any records you need are confirmed with the quote. We work on accessible toilets and changing rooms, vanity units and basins and urinals and WCs, and what we’re called in for most is failed joints along IPS and cubicle panels and users noticing mouldy joints. Searching for sealant specialists in Northway? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Around Northway, washroom work typically comes one building at a time. A list and photographs let us quote and plan so it’s done in one visit where possible.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Cost factors for washrooms and wet areas

To price the job, we consider:

  • Specialist products, such as fire-rated or hygienic sealants
  • Whether old sealant has to be cut out first
  • The size and state of each joint
  • Phasing around occupants

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

What to include in your enquiry

A few photos plus some basic facts will normally do. Please tell us:

  • Whether an asbestos survey exists
  • Clear photographs of the problem areas
  • Access details, including height
  • Where the site is, with the postcode

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or email the details over.

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Keep extract fans working and vents clear
  • Respect the cure time before reopening each room
  • Mention any site permits or estates rules at quote stage
  • Clear standing water from shower floors where possible

Each room goes back into use only when the sealant has cured enough. You will be told when showers and basins can be used again, and it helps if signs stay up until then.

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

What we can’t put right

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

  • Vanity carcasses that have swollen
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Mould caused by poor ventilation, which will return until the extract is fixed

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Joints and surfaces we work on

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

Common questions from Northway clients

Can you work around term dates at a campus such as Oxford Brookes University Marston Road Site?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Northway off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is old silicone taken out first?

The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Will all the toilets be closed at once?

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

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Busy facilities in and around Northway

There are six care or nursing homes within about 2 miles of Northway. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Rooms are done a few at a time at times agreed with the home. Plenty of hotels sit less than 2 miles from Northway. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The work can go floor by floor, agreed with housekeeping.

On an industrial estate such as Shotover Trading Estate (1.7 miles south-east of Northway), staff toilets, showers and canteens are where sanitary sealant takes the most wear. For a campus such as Oxford Brookes University Marston Road Site, 0.8 miles south-west of Northway, showers in residences and washrooms in teaching blocks can be programmed around term dates.

Common problems we fix in Northway

Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.

Most enquiries start with one or more of the following:

  • Mould spotting along silicone joints
  • Resealing that didn’t last because the old bead stayed
  • Stained sealant around pans and urinals
  • Complaints from staff, guests or users about tired washrooms

For centre management at a site such as Clarendon Shopping Centre, which lies south-west of Northway, washroom work is planned around footfall.

Before you book anyone

  • Are they CHAS accredited or on Constructionline?
  • Who will actually carry out the work
  • Will failed sealant be removed rather than covered?
  • Proof of insurance

Questions to ask before you appoint anyone

How the job changes by surface

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively, so their joints often need renewing sooner.

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Stained or split joints here trap smells and make the room look neglected.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. For a job in Northway, the main thing is a clear picture of the work, so send photographs of each area. You’ll then get a fixed price for the work.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work
  • Explain the parking and delivery arrangements

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
