We are fully insured. Every resealed washroom carries our 12-month guarantee.

Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Woodside is the same: the right product in a properly prepared joint.

FAQs: Woodside

Which documents can you supply for work in Woodside?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Will the toilets in our Woodside building be out of use?

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.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Do you work in hospitals, clinics and care homes?

We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Is Woodside in your area?

Yes. We take on work across Woodside, with one number for every area we cover.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Note failing joints building by building
  • Avoid scourers and harsh descalers on silicone
  • Don’t leave an open joint at a basin or tray
  • Add sealant joints to planned maintenance checks

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

What happens if it’s left?

A tired washroom says a lot about how a building is run. Visitors notice black sealant before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Around Woodside, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

What we can’t put right

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

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Loose panels, vanity units or tiles, which need fixing first
  • Water escaping beneath the floor rather than through a joint

If you are not sure, just ring 01277 525 020 or use the quote form and we’ll give you a straight answer.

What we seal

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

Common problems we fix in Woodside

Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead, so it soon lets go.

Look out for the following:

  • Split or peeling sealant at shower trays
  • Mould spotting along silicone joints
  • Panel joints letting water behind
  • Urinal joints that look unhygienic

For a hall at a building such as Church of St Mary, resealing the kitchen and toilets can be fitted between bookings.

What to look for in a quote

  • Will CSCS-carded applicators be on site?
  • Whether primer will be used where the manufacturer specifies it
  • How they’ll work around occupants
  • Whether old or failed sealant will be cut out, not overlaid

How to choose a sealant contractor

On site: what to expect

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Woodside need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

What we need from you

  • Make sure the joints can be reached
  • Tell us what induction or permit system the site runs
  • Have the specification and drawings to hand

Ask for a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or send photos by email.

What the job involves on each surface

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and look unhygienic.

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath and point it out if water appears to rise from below.
