Washroom sealing for New Winton sites

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

Commercial clients in New Winton

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Washroom sealing in New Winton

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. We work on showers, trays and wet room floors, urinals and WCs and IPS panels and cubicles, and the failures we are asked to look at most are resealing that didn’t last because the old bead stayed and failed sealant in a tea point or staff kitchen. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in New Winton is the same: the right product in a properly prepared joint.

Travel to smaller places like New Winton is planned so the work is finished on one visit. Photos of each washroom and a count of rooms help us quote and plan.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Washroom sealing in New Winton: the local picture

New Winton is within about 3 miles of the coast, and seaside hospitality normally has a peak season that works washrooms hard. Washrooms used guest after guest wear their sanitary silicone faster, and the quieter months are the natural time to reseal. The 2 miles around New Winton include two care or nursing homes. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Rooms are done a few at a time at times agreed with the home.

At a school such as Ross High School, changing rooms and kitchens need cleanable joints as much as the toilets. Staff changing rooms and patient toilets at places like Roodlands General Hospital (5.1 miles east of New Winton) need cleanable, sound silicone.

New Winton is about 5 miles east of Musselburgh, in East Lothian.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Hollow tiles or loose panels behind the joint
  • A room that stays damp because ventilation isn’t working
  • Water from plumbing, not from a joint

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly.

What we seal

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

What we are called out for in New Winton

Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

Typical triggers for a call:

  • Open joints along basins and vanity units
  • Open joints at the base of cubicle panels
  • Sealant laid over old silicone and now peeling
  • Washrooms that look worn because of the sealant

If you manage an office at a site such as Macmerry Business Park, which lies north-east of New Winton, the washrooms and tea points can be done a floor at a time.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How the existing material will be dealt with
  • What site paperwork they can supply

Our contractor checklist

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. Tell us who will meet us and how to get in at your building near New Winton. That goes into the plan alongside the quote.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. We clean and dry every surface so the new sealant can grip.
  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.

What we need from you

  • Point out any areas we must not close
  • Confirm the product named in the specification
  • Send your site hours and access windows

Questions we are asked in New Winton

Would you work within a site like Roodlands General Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is New Winton too far out for you?

Not at all. New Winton is within our area. Our area covers all of Scotland, cities, towns and islands alike. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What guarantee comes with washroom resealing?

Our workmanship has a 12-month guarantee backed by public liability insurance.

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 photographs and a postcode.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives in most cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

Why it’s worth doing now in New Winton

Waiting for a holiday closure can leave failing joints in place for a long time. With phasing, the work can go ahead while most facilities stay open. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like New Winton, a repair visit takes planning, so it’s better to act early.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

What affects the price in New Winton

These are the things that shape the price:

  • Location, for remote and island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint
  • Whether old sealant has to be cut out first

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • Where the site is, with the postcode
  • Specification clauses that apply
  • Drawings or a marked-up plan, if available
  • How the joints are reached, and at what height

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
