Need washroom sealing in Brockham?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When it isn’t the sealant

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

  • Condensation from failed extract fans
  • Swollen or delaminated boards behind panels or vanity tops
  • Hollow tiles or loose panels behind the joint

If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Joints and surfaces we work on

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

Washroom sealing for commercial buildings in Brockham

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Our workmanship is guaranteed for 12 months. If you have stained sealant around pans and urinals and open joints at the base of cubicle panels, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Brockham, preparation and product choice get the time they need.

Smaller places such as Brockham still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould usually can’t be cleaned, so it is cut out and replaced.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Cost factors for washrooms and wet areas

Before we quote, we look at:

  • The size and state of each joint
  • Any access equipment needed
  • Quantities, in metres or numbers
  • Specialist products, such as fire-rated or hygienic sealants

A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • Specification clauses that apply
  • The postcode of the building
  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Brockham need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

What we need from you

  • Flag any permit to work we will need
  • Warn occupants and staff about the work
  • Explain the parking and delivery arrangements

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Common questions from Brockham clients

Do you work in occupied care homes around Brockham?

Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.

Would you work within a site like Dorking Community Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

What happens if old sealant might contain asbestos?

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

Do you do washroom sealing in healthcare settings?

Yes. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Signs you need washroom sealing in Brockham

Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and say if it needs a plumber or another trade.

Any of the following is a good reason to get the joints checked over:

  • Sealant lifting along a tray edge
  • Open joints along basins and vanity units
  • Urinal joints that look unhygienic
  • Sealant laid over old silicone and now peeling

For a site such as Dorking Community Hospital (2.3 miles west of Brockham), sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Building owners, agents and FMs in Brockham

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
