Washroom sealing across Streat

Streat: questions and answers

Is a smaller place like Streat outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

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

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you guarantee washroom sealing?

Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

About our washroom sealing in Streat

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 accessible toilets and changing rooms, showers, trays and wet room floors and vanity units and basins, and the failures we’re asked to look at most are gaps where vanity tops meet the wall and open joints at the base of cubicle panels. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Streat, that means joint design, primers and backing rod as standard.

Farm shops, cafés and venues in converted rural buildings around places like Streat have busy toilets and kitchens. We plan the work around bookings and opening times.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Wet areas in Streat’s workplaces

Streat lies roughly 40 miles out from central London. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available.

Where you’re responsible for a hall attached to a building such as Streat Church, its kitchen and toilets need sealant that stays cleanable. Toilets at colleges like Plumpton College, 1 mile to the south of Streat, take heavy use from students and staff alike. At a university such as University of Sussex, which lies north-east of Streat, summer is the usual window for resealing residence bathrooms.

Streat is about 3 miles south-east of Burgess Hill, in East Sussex. Commercial clients in Streat use us for work on washrooms and wet areas. We work across 308 places in East Sussex. We also cover Brighton, around 6 miles from Streat.

Nearby places we also cover include Plumpton (1 mile south-east), Plumpton Green (1 mile north-east), East Chiltington (1 mile east), Ditchling Common (2 miles north) and Chiltington (2 miles east).

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Rural sites near Streat may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Preparing the site

  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand

Different surfaces, different methods

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.

Kitchens and tea points

We plan kitchen sealing around when the kitchen is in use. Your site hours and access windows set the timing.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Leaks through tanking or membranes below the finishes
  • A room that stays damp because ventilation isn’t working
  • Panel boards already damaged by water

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

Joints and surfaces we work on

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

Why it’s worth doing now in Streat

A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Around Streat, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Why clients in Streat choose us

  • Specification-led, product-correct work
  • Colour options checked against the specified product
  • One number for every site we cover
  • A Constructionline member, so easy to vet

See our cost guide or our accreditations.

Aftercare for building managers

After handover, a little attention goes a long way:

  • Act on the first split you see at a shower tray
  • Photograph and log failed joints across the estate
  • Avoid scourers and harsh descalers on silicone
  • Report faulty extraction promptly

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.

A split joint at a shower tray can leak for a long time before anyone sees it. By then, other trades may be needed as well, so reseal when you first spot a split.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
