Work for main contractors and building owners

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

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

How we handle washroom sealing in Wickham

Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. If you are dealing with stained or open joints at kitchen sinks and worktops and complaints from staff, guests or users about tired washrooms, we can put it right, on IPS panels and cubicles, urinals and WCs and showers, trays and wet room floors alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Wickham, preparation and product choice get the time they need.

Pub and restaurant kitchens around smaller places like Wickham work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.

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

Common problems we fix in Wickham

Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.

If one of these sounds familiar, it’s time for a closer look:

  • Washrooms that look worn because of the sealant
  • Open joints along basins and vanity units
  • Black mould inside silicone joints that cleaning can’t shift
  • A new bead over an old one coming away

At a hospital like Knowle Hospital, 1.5 miles to the south-west of Wickham, patient and staff washrooms are best done in short phases agreed with the ward.

What your quote should include

  • Can the work be phased to keep areas open?
  • Their public liability cover
  • Will CSCS-carded applicators be on site?
  • Will failed sealant be removed rather than covered?

Questions to ask before you appoint anyone

Questions we are asked in Wickham

Is Wickham off your patch?

Not at all. Wickham is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Would you work within a site like Knowle Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

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.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Wet areas in Wickham’s workplaces

Central London is about 63 miles from Wickham. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open. There are several hotels within about 2 miles of Wickham. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. We work a handful of rooms at a time, so the hotel keeps letting the rest.

Office toilets at parks like Knowle Village Business Park, 1.5 miles south-west of Wickham, take steady weekday use, and mouldy silicone soon shows. Where you are responsible for a hall attached to a building such as Church of St Nicholas, its kitchen and toilets need sealant that stays cleanable.

Wickham is about 3 miles north of Fareham, in Hampshire. Across the PO17 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Hampshire coverage takes in 723 places. Our Portsmouth page has more on work in that area, about 8 miles away.

Anyone looking for washroom sealing in PO17 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. We cover commercial and managed buildings on The Square, Station Road and Bridge Street. Wickham sits on or close to the A32 and A334, useful when we plan access and materials. Just outside Wickham, we also work in Shedfield (1 mile north-west), Shirrell Heath (2 miles north), Kingsmead (2 miles north-east), Woodend (2 miles north-east) and Mislingford (2 miles north). Nearby towns on our patch include Winchester (12 miles north-west), Gosport (7 miles south), Havant (9 miles east), Eastleigh (8 miles north-west), Fareham (3 miles south) and Horndean (8 miles east).

Local landmarks in Wickham

Other landmarks nearby include Fareham Shopping Centre (3.2 miles south) and Carron Row Farm Museum (3.5 miles south-west). Not far away are St Clair's Meadow and Portsdown Hill.

Quoting for work in Wickham

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Backing rod, priming and other preparation
  • Access and working height
  • The total length or number of joints
  • Travel to remote or island sites

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

Details that help us quote

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

  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area
  • Specification clauses that apply
  • Access details, including height

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

Why it’s worth doing now in Wickham

Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. A full reseal deals with it and your cleaning team stops chasing it. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Why us?

  • CSCS-carded applicators
  • Coloured sealants to suit the setting, where available
  • 12 months’ guarantee on every job
  • One number for every site we cover

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. 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. What matters most for a job in Wickham is a clear list of what needs doing. A fixed quote follows.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Before we start on site

  • Tell staff and tenants when we will be in
  • Confirm the product named in the specification
  • Flag any permit to work we’ll need

Request a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Advice

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

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

If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think before you book.

What we seal

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