Washroom sealing for businesses in Stonestreet Green

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

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Loose panels, vanity units or tiles, which need fixing first
  • Water escaping beneath the floor rather than through a joint
  • Mould caused by poor ventilation, which will return until the extract is fixed

If in doubt, call the office on 01277 525 020 or use the quote form and we’ll say what we think before you book.

What we seal

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

About our washroom sealing in Stonestreet Green

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. Our workmanship is guaranteed for 12 months. If you’re dealing with panel joints letting water behind and failed sealant in a tea point or staff kitchen, we can put it right, whatever the surface. Most enquiries from Stonestreet Green start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Halls and community buildings near places like Stonestreet Green are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

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 spell out the cover before we begin.

After the work

A few simple habits keep the new joints working:

  • Share your site rules when you send details
  • Note failing joints building by building
  • Squeegee showers and trays after busy periods
  • Avoid scourers and harsh descalers on silicone

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Replacing it early keeps the job to a reseal.

Keeping Stonestreet Green washrooms open while we work

Stonestreet Green is about 53 miles from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, which is why the work is phased.

Schools such as Aldington Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays. For centre management at a site such as Ashford Retail Park, 3 miles to the north-west of Stonestreet Green, washroom work is planned around footfall. Church halls and community buildings, such as those at Church of St Martin, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Stonestreet Green is about 5 miles south-east of Ashford, in Kent. We cover commercial sites throughout Stonestreet Green, for single jobs and planned programmes alike.

How the quote is worked out

Before we quote, we look at:

  • Distance, for remote addresses
  • How much existing material needs removing
  • Backing rod, priming and other preparation
  • Any access equipment needed

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • Specification clauses that apply
  • The type of building and who uses it
  • Approximate linear metres or a joint schedule
  • When you need the work done

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or use the quote form.

Commercial clients in Stonestreet Green

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Stonestreet Green. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Stonestreet Green: questions and answers

Will all the washrooms in our Stonestreet Green building be closed at once?

Rarely all at once: work is phased so some facilities are always available. Each area is handed back once the sealant has cured enough to use.

Can you work on a hospital site such as William Harvey Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How much does the work cost?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

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.

Can you handle several sites?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
