Questions we’re asked in Pennington

Do hotels near Pennington have to close for sealant work?

Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.

Is Pennington too far out for you?

Not at all. Pennington is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Do you use special sealant for toilets and showers?

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

Can washrooms stay open while you work?

Only the area we are working in is closed. Each room reopens after the sealant’s cure time, then we move on.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

About our washroom sealing in Pennington

In a commercial washroom, sealant is normally the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. Most enquiries involve kitchen worktop joints that can’t be kept clean and shower tray joints that have opened up, on accessible toilets and changing rooms, showers, trays and wet room floors and kitchens and tea points. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Pennington, preparation and product choice get the time they need.

In a smaller place such as Pennington, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Wet areas in Pennington’s workplaces

Pennington 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. Washrooms used guest after guest wear their sanitary silicone faster, and the quieter months are the natural time to reseal. The area within 2 miles of Pennington holds several hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest.

Healthcare washrooms on sites such as Lymington New Forest Hospital, 1.4 miles north of Pennington, are resealed area by area, under the site’s own infection-control rules. Schools such as Priestlands School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Pennington is about 1 mile south-west of Lymington, in Hampshire. Anywhere in SO41, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 723 places across Hampshire fall within our area, including Pennington.

Leave it or put it right?

Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. In a smaller place such as Pennington, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Diagnose, treat, sign off

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 Pennington is a clear list of what needs doing, so send photos of each area. A fixed quote follows.

  1. We agree which washrooms close and when.
  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 confirm reopening times for each washroom.

Getting the site ready

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Panel boards already damaged by water
  • Loose panels, vanity units or tiles, which need fixing first
  • Condensation from failed extract fans

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly.

What we seal

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

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

When to call us in Pennington

Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.

What tends to prompt an enquiry:

  • Stained sealant around pans and urinals
  • Open joints at the base of cubicle panels
  • Split or peeling sealant at shower trays
  • Failed sealant behind washroom basins

For a hotel such as Londesborough Hotel (0.9 miles north-east of Pennington), resealing en suites a few rooms at a time keeps the rest available.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • Will failed sealant be removed rather than covered?
  • Their approach to joint depth and backing
  • Their public liability cover
