Washroom sealing in Bouldnor

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

How we handle washroom sealing in Bouldnor

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Most enquiries involve discoloured joints around urinals and WC pans and shower tray joints that have opened up, across urinals and WCs, showers, trays and wet room floors and vanity units and basins. One point of contact handles commercial sealant work in Bouldnor from the first photos to the final walk-round, whether it’s one building or several.

Halls and community buildings near places like Bouldnor are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Work for main contractors and building owners

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

What happens if it’s left?

Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. One visit to deal with every failing joint makes more sense than several trips to a place like Bouldnor. Photos of every joint help us quote for the whole job.

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

Why appoint us

  • A fixed quote before work starts
  • Work to your specification and the manufacturer’s guidance
  • One contact handling all your sites
  • Coloured sealants to suit the setting, where available

Quoting for work in Bouldnor

There’s no standard rate for sealant work, because every site is different. What we look at:

  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing
  • Site requirements such as inductions and permits

A quote for washrooms and wet areas depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

What we need to price the job

However big the job, the same details help:

  • Where the site is, with the postcode
  • When you need the work done
  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back

For a fixed quote, speak to us on 01277 525 020 or send photos by email. You can also send details through our quote form.

Questions we’re asked in Bouldnor

Do you take on work at healthcare sites like Lymington New Forest Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will our hotel in Bouldnor need to close for the work?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we’ll plan around them.

Are you CHAS accredited?

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

Is it possible to just clean mouldy silicone?

Normally not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.

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

The whole of the old bead is removed and the surfaces cleaned before resealing. It’s the difference between a joint that lasts and one that peels.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Diagnose, treat, sign off

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Bouldnor, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  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.

What we need from you

  • Tell us which areas need to stay in use
  • Make sure the joints can be reached
  • Arrange parking or a loading space

Advice

Surface by surface

Showers and trays

A tray that rocks or has cracked won’t be fixed by sealant and we flag that beforehand.

Kitchens and tea points

In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Food-safe sealants are used where food may touch the joint.

Keeping Bouldnor washrooms open while we work

Bouldnor sits close to the coast, within about 1 mile, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Heavy seasonal use is hard on shower and basin sealant, which is why off-season resealing makes sense. There are several hotels within about 2 miles of Bouldnor. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest.

Church halls and community buildings, such as those at Church of St Swithin (old), have kitchens and toilets used by many groups, and their sanitary sealant works hard. For a school such as Yarmouth Church of England Aided Primary School, washroom and kitchen sealant can be renewed around term dates. For a site such as Lymington New Forest Hospital (5.2 miles north-west of Bouldnor), sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Bouldnor is about 5 miles south-east of Lymington, in the Isle of Wight. Across the PO41 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Bouldnor is one of 125 places in the Isle of Wight on our list. Sites around Southampton have their own page, roughly 15 miles from Bouldnor.

We take on washrooms and wet areas across the PO41 postcode area. Buildings on The Vineyard, Port La Salle and Waters Edge are within our area. We also cover Yarmouth (1 mile west), Cranmore (1 mile east), Hamstead (2 miles north-east), Shalfleet (3 miles east) and Thorns Beach (4 miles north). Nearby towns on our patch include Newport (8 miles east), Ryde (14 miles east), Cowes (8 miles north-east), Sandown (14 miles east), Shanklin (14 miles east) and Ventnor (14 miles south-east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you speak to us on 01277 525 020 or email a schedule or drawings.

When to bring in a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

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.
