Need washroom sealing in New Milton?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Leave it or put it right?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

Pricing washrooms and wet areas depends on quantities, condition and access. Ask us for a fixed quote.

Washroom sealing in New Milton, done properly

You can’t shut every toilet in an office, school or hotel at once. 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. Give us your site hours and access windows and the phasing is planned around them. If you’re dealing with black mould inside silicone joints that cleaning can’t shift and gaps where vanity tops meet the wall, we can help, on IPS panels and cubicles, kitchens and tea points and urinals and WCs alike. Most enquiries from New Milton start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Pub and restaurant kitchens around smaller places like New Milton work hard on their joints. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable.

Work we carry out in Hampshire comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email drawings and photos and we’ll come back to it.

Owners, agents and contractors

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

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

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. What matters most for a job in New Milton is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

What we need from you

  • Point out parking and an unloading spot
  • Send any specification or drawings in advance
  • Agree which areas must stay open

Cost factors for washrooms and wet areas

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Quantities, in metres or numbers
  • The product specified
  • The site’s rules and procedures
  • Distance, for remote addresses

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Access details, including height
  • Your programme or deadline
  • Photos of the joints, close up and from further back
  • The site address and postcode

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Swollen or delaminated boards behind panels or vanity tops
  • Water escaping beneath the floor rather than through a joint

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

Surfaces we seal

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

After the work

For the best life from the joints:

  • Clean sealant with gentle products and a soft cloth
  • Keep extract fans working and vents clear
  • Keep washrooms out of use until we say the sealant has cured
  • Act on the first split you see at a shower tray

Ventilation is half the battle. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Common questions from New Milton clients

Do you work in occupied care homes around New Milton?

Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.

Is a smaller place like New Milton outside your area?

No. Places such as New Milton are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Do you work in hospitals, clinics and care homes?

Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

What happens if old sealant might contain asbestos?

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

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

The failed bead is always removed. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

Commercial washrooms in New Milton

The sea is no more than about 2 miles from New Milton, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Showers and en suites in constant use are where silicone moulds and splits first, so resealing in the quieter months keeps rooms ready. The 2 miles around New Milton include five care or nursing homes. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Each room is kept out of use only as long as the sealant needs.

For a school such as The Arnewood School, washroom and kitchen sealant can be renewed around term dates. Staff changing rooms and patient toilets at places like Lymington New Forest Hospital, 5.1 miles to the east of New Milton, need cleanable, sound silicone. Welfare facilities in units on estates such as Gore Road Industrial Estate, 0.5 miles to the west of New Milton, have showers, toilets and kitchens with sealant that works hard.
