Washroom sealing in Bentworth

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. We work on vanity units and basins, urinals and WCs and kitchens and tea points, and the failures we are asked to look at most are split or peeling sealant at shower trays and stained or open joints at kitchen sinks and worktops. For commercial sealant work in Bentworth, you deal with one contact from quote to sign-off, whether it’s one building or several.

Smaller places such as Bentworth still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we will arrange a return visit.

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. 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. Rural sites near Bentworth may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

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

Before we start on site

  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements
  • Have the specification and drawings to hand

Ask for a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or send details through our quote form.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Hollow tiles or loose panels behind the joint
  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Panel boards already damaged by water

If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.

Questions we’re asked in Bentworth

Is Bentworth too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is hospital work, at somewhere like Alton Community Hospital, something you do?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives in the majority of cases. We use neutral-cure versions on stone, some metals and near mirrors.

Do you need to remove the old sealant?

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 phase washroom resealing?

The work is phased so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we’ll plan around them.

Can you quote from photos?

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

How do I request a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or use the quote form. Include photographs or drawings if you have them.

Why it’s worth doing now in Bentworth

Sealing on top of old silicone saves nothing. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Full removal and proper cleaning is what makes the new joint last. For buildings around smaller places like Bentworth, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Work for main contractors and building owners

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Bentworth. One quote can cover more than one site, which keeps the paperwork simple.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

How the job changes by surface

Changing rooms and gyms

We phase work so not every changing area is closed at once. Phasing follows your site hours and access windows.

Urinals and WC pans

We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.

Wet areas in Bentworth’s workplaces

Bentworth lies roughly 47 miles out from central London. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.

Where you are responsible for a hall attached to a building such as St. Mary's Church, its kitchen and toilets need sealant that stays cleanable. For a site such as Alton Community Hospital, 2.8 miles to the south-east of Bentworth, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. Schools such as St Mary's Bentworth Church of England Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
