Washroom sealing for businesses in Felsted

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

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Felsted may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. We clean and dry every surface so the new sealant can grip.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Agree which areas must stay open
  • Let building users know which areas are affected

Washroom sealing in Felsted

Closing all the facilities in a building isn’t an option. Work is phased by room or by section, 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. We work on kitchens and tea points, accessible toilets and changing rooms and IPS panels and cubicles, and the failures we’re asked to look at most are stained or open joints at kitchen sinks and worktops and sealant stained black around basins and showers. Looking for mastic applicators who cover Felsted? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Smaller places such as Felsted 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.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Questions about Felsted

Is Felsted too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Will the toilets in our Felsted building be out of use?

Normally only some of them, for a short time. We work in phases so other facilities stay open. We’ll tell you the curing time for the product before we start.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Is it possible to just clean mouldy silicone?

Normally not. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacement is the lasting fix.

How much does the work cost?

We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • A dripping waste or valve behind a panel
  • Leaks through tanking or membranes below the finishes
  • Loose panels, vanity units or tiles, which need fixing first

Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Do you need washroom sealing in Felsted?

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.

These are often picked up first by site or facilities staff:

  • Shower tray joints that have opened up
  • Mould spotting along silicone joints
  • Stained or open joints at kitchen sinks and worktops
  • Failed joints along IPS and cubicle panels

Where you’re responsible for a hall attached to a building such as Church of the Holy Cross, its kitchen and toilets need sealant that stays cleanable.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • Proof of insurance
  • Whether primer will be used where the manufacturer specifies it
  • Their pre-qualification and accreditations

Choosing a commercial sealant contractor

Maintenance after handover

For the best life from the joints:

  • Inspect washroom sealant regularly
  • Keep a record of which washrooms need attention
  • Report faulty extraction promptly
  • Don’t leave trays and floors sitting wet

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Leave it or put it right?

When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Converted and older buildings near places like Felsted tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why us?

  • CSCS-carded applicators
  • Workmanship guaranteed for 12 months
  • Commercial sealant work since 2005
  • One contact handling all your sites
