Washroom sealing for Southrope sites

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

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 our CSCS-carded applicators are used to working under those rules.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Washroom sealing in Southrope

Whether it’s a single toilet block in Southrope or a programme across several buildings, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. We work on kitchens and tea points, showers, trays and wet room floors and accessible toilets and changing rooms, and the failures we’re asked to look at most are black mould inside silicone joints that cleaning can’t shift and sealant laid over old silicone and now peeling. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Southrope it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Farm shops, cafés and venues in converted rural buildings around places like Southrope 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.

Toilets, showers and kitchens around Southrope

Central London is about 46 miles from Southrope. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.

For a site such as Alton Community Hospital, 4.6 miles south-east of Southrope, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. Where you’re responsible for a hall attached to a building such as Church of St. Mary, its kitchen and toilets need sealant that stays cleanable.

Southrope is about 4 miles north-west of Alton, in Hampshire. We cover Southrope and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 723 places in Hampshire. There’s a separate page for Reading, about 17 miles away.

Anyone looking for washroom sealing in RG25 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Your questions answered

Must every washroom in our Southrope building shut while you work?

Rarely all at once: work is phased so some facilities are always available. We will tell you the curing time for the product before we start.

Is Southrope too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Is it OK to put new silicone on top of the old?

The failed bead is always removed. New silicone won’t stick to the old, so sealing over it soon peels.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.

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.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Can washrooms stay open while you work?

Just the room being resealed is out of use. Rooms go back into use once the sealant has cured, then we move on.

Why it’s worth doing now in Southrope

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. One visit to deal with every failing joint makes more sense than several trips to a place like Southrope. Photos of every joint help us quote for the whole job.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • Colours chosen to suit frames, cladding or finishes where possible
  • Constructionline member for supplier checks
  • A range of standard colours, depending on the product

Commercial clients in Southrope

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Looking after the joints

To get the most from the new sealant:

  • Don’t leave trays and floors sitting wet
  • Note failing joints building by building
  • Report faulty extraction promptly
  • Leave signs up until the cure time is over

Ventilation is half the battle. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • A room that stays damp because ventilation isn’t working
  • Swollen or delaminated boards behind panels or vanity tops
  • A dripping waste or valve behind a panel

If you are not sure, just call 01277 525 020 or email us and we will give you a straight answer.

Surfaces we seal

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

Our process

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Southrope can be grouped with others nearby. You will have a fixed quote before work starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

Before we start on site

  • Explain the parking and delivery arrangements
  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs
