Questions about Rowledge

Is Rowledge too small for you to travel to?

Not at all. Rowledge is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work around term dates at a campus such as University for the Creative Arts?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Will all the toilets be closed at once?

Only the area we’re working in is closed. Rooms go back into use once the sealant has cured and we start the next.

Are you CHAS accredited and on Constructionline?

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

Is old silicone taken out first?

The failed bead is always removed. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

Washroom sealing in Rowledge

Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. If you’re dealing with gaps where vanity tops meet the wall and resealing that didn’t last because the old bead stayed, we can put it right. A single leaking joint is often how a building in Rowledge first comes to us: we look at the rest while we are there and tell you what we find.

Farm shops, cafés and venues in converted rural buildings around places like Rowledge have busy toilets and kitchens. Tell us your opening times and quiet periods and we will plan around them.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

When to bring in a specialist

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

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 easy to get wrong without experience.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work. If others near Rowledge need work, visits can be combined. A fixed quote is given before anything starts.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Send any specification or drawings in advance
  • Arrange parking or a loading space
  • Make sure the joints can be reached

Getting a fixed quote

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send photos by email.

Advice

Wet areas in Rowledge’s workplaces

Rowledge is about 38 miles from central London, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, which is why the work is phased.

For a hall at a building such as Saint James, resealing the kitchen and toilets can be fitted between bookings. At a hospital like Chase Community Hospital, 5.6 miles south of Rowledge, patient and staff washrooms are best done in short phases agreed with the ward.

Rowledge is about 2 miles south-west of Farnham, in Surrey. We cover Rowledge and the rest of Surrey, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Surrey coverage takes in 379 places, from busy centres to rural villages. Our Reading page has more on work in that area.

If you need washroom sealing in GU10, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. For a building on High Street, Chapel Road and Bell Lane or nearby, we can quote for washrooms and wet areas. Just outside Rowledge, we also work in Holt Pound (1 mile west), Boundstone (1 mile north-east), Wrecclesham (1 mile north), Shortheath (1 mile north-east) and Batt's Corner (1 mile south). Further afield, our area takes in Guildford (12 miles east), Woking (14 miles north-east), Camberley (11 miles north), Frimley (10 miles north-east), Haslemere (8 miles south-east) and Cranleigh (15 miles east).

What’s near Rowledge

We work on buildings around Underdown nature reserve, Weydon School and The Hare and Hounds pub. The nearest railway station is Bentley (Hampshire) station, about 2 miles west. A little further out are Chase Community Hospital (5.6 miles south) and Museum of Farnham (2.2 miles north). Open spaces near Rowledge include Beacon Hill and Farnham Heath.

Maintenance after handover

To get the most from the new sealant:

  • Tell us about infection-control or permit rules before we quote
  • Keep washrooms out of use until we say the sealant has cured
  • Add sealant joints to planned maintenance checks
  • Act on the first split you see at a shower tray

Each room goes back into use only when the sealant has cured enough. We’ll tell you when the wet areas can be used and signage stays in place until that time.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

Common problems we fix in Rowledge

Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.

Most enquiries start with something like this:

  • Stained or open joints at kitchen sinks and worktops
  • Sealant stained black around basins and showers
  • Stained sealant around pans and urinals
  • Washrooms that look worn because of the sealant

Units at estates like Grovebell Industrial Estate, 1.3 miles to the north of Rowledge, have welfare blocks whose showers and toilets see shift after shift.

What to look for in a quote

  • How the joint faces will be prepared and primed
  • Their public liability cover
  • How they handle RAMS and site documents
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

What the job involves on each surface

Kitchens and tea points

Kitchen work can be phased around service. Tell us your site hours and access windows and we will plan around them.

Urinals and WC pans

Floor joints around WC pans are often forgotten. They are checked with everything else.

What sealant work can’t fix

Honesty saves time and money. New sealant won’t cure:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Loose panels, vanity units or tiles, which need fixing first
  • Swollen or delaminated boards behind panels or vanity tops

If you’re not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer.
