Keeping Hyde washrooms open while we work

Central London is about 60 miles from Hyde, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, so we work a block of facilities at a time. Hyde has plenty of hotels close by, all within 2 miles. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.

At a college such as Peter Symonds College, 0.5 miles west of Hyde, washroom and kitchen sealant is best renewed in the holidays or in phases during term. For a site such as Royal Hampshire County Hospital (0.9 miles south-west of Hyde), sanitary joints in clinical areas need sound, cleanable sealant and a careful method. Student showers at universities like University of Winchester (0.9 miles south-west of Hyde) see more use than most, and their silicone shows it.

Hyde is about 1 mile north of Winchester, in Hampshire. Businesses, contractors and managing agents in Hyde can call on us for washrooms and wet areas, as part of our coverage of Hampshire. Hyde is one of 723 places in Hampshire on our list. Southampton is covered too, some 11 miles away.

Commercial sites across SO23, SO22 and SO20 are covered for washrooms and wet areas. If your site is on Elm Road, Swan Lane and City Road or close by, we can quote for washrooms and wet areas. If your building is just outside Hyde, we cover Abbotts Barton (1 mile north-east), Winchester (1 mile south), Weeke (1 mile west), Highcliffe (1 mile south-east) and Bar End (1 mile south). Bigger towns within reach include Eastleigh (7 miles south), Andover (12 miles north-west), Totton (13 miles south-west), Chandler's Ford (7 miles south-west), Hedge End (11 miles south) and Romsey (9 miles south-west).

About our washroom sealing in Hyde

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. We work on showers, trays and wet room floors, urinals and WCs and accessible toilets and changing rooms, and the usual reasons a site gets in touch are sealant stained black around basins and showers and open joints at the base of cubicle panels. For commercial sealant work in Hyde, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Pub and restaurant kitchens around smaller places like Hyde work hard on their joints. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable.

Work we carry out in Hampshire comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or send photos by email and we’ll come back to it.

Why act early in Hyde

Washrooms shape how visitors judge a building. Visitors notice black sealant even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. In a smaller place such as Hyde, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Questions about Hyde

Could you schedule work at a campus like University of Winchester for the vacation?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you work in occupied care homes around Hyde?

Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

How many days will you need on site?

It depends on the scope, though a typical visit normally takes a morning or so for a small washroom, longer where showers and changing rooms are included. For bigger or phased jobs, we’ll set out a timescale with the quote.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Work in places the size of Hyde is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  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. The failed silicone is stripped and every face scraped clean of residue.
  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.

Preparing the site

  • Tell us which areas need to stay in use
  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

Owners, agents and contractors

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Hyde can sit alongside others in a wider programme.

Different surfaces, different methods

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone and we choose a neutral-cure grade for them.

Kitchens and tea points

Worktop, sink and splashback joints in tea points take water and food. Sound joints keep those surfaces easy to clean.

Cost factors for washrooms and wet areas

These are the things that shape the price:

  • Site requirements such as inductions and permits
  • The total length or number of joints
  • Backing rod, priming and other preparation
  • How accessible the joints are

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Before you send an enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • How the joints are reached, and at what height
  • What the building is and how it’s used
  • The site address and postcode
  • Clear photographs of the problem areas

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or send photos by email.

What sealant work can’t fix

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

  • A room that stays damp because ventilation isn’t working
  • Water escaping beneath the floor rather than through a joint
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly.
