Need washroom sealing in Maidenbower?

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

What we’re called out for in Maidenbower

Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We look for it before resealing and say if it needs a plumber or another trade.

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

  • Sealant lifting along a tray edge
  • Open joints at the base of cubicle panels
  • Gaps where vanity tops meet the wall
  • Kitchen worktop joints that can’t be kept clean

Toilets at colleges like Crawley College, 1.6 miles north-west of Maidenbower, take heavy use from students and staff alike.

Questions to ask before you appoint anyone

Washroom sealing in Maidenbower

Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. If you’re dealing with open joints at the base of cubicle panels and sealant laid over old silicone and now peeling, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Maidenbower it comes down to the same thing: the right product in a properly prepared joint.

Pub and restaurant kitchens around smaller places like Maidenbower work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

What affects the price in Maidenbower

Each job is priced on its own details. The things that drive the figure:

  • Specialist products, such as fire-rated or hygienic sealants
  • Whether the work must be split into stages
  • Access and working height
  • The total length or number of joints

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • The type of building and who uses it
  • The site address and postcode
  • Rough lengths or quantities, or drawings if you have them
  • How the joints are reached, and at what height

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, phone 01277 525 020 or email a schedule or drawings.

Your questions answered

Can you work on a hospital site such as Crawley Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is Maidenbower off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

How long before the toilets can reopen?

That varies with the sealant and the room temperature. You’ll get a reopening time for each area before we leave it.

Do you do washroom sealing in healthcare settings?

We work in clinics, hospitals and care homes. Tell us what records you need and we’ll confirm with the quote.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Site staff or a sealant specialist?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

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.

Surface by surface

Basins and vanity tops

A failed joint along a vanity unit lets water into the carcass. Resealing early protects the unit.

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath, and we will say if the trouble looks to be beneath the floor.

Leave it or put it right?

Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Small buildings around Maidenbower suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

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.

Why us?

  • RAL and finish matching where the product range allows
  • Coloured sealants to suit the setting, where available
  • Commercial sealant work since 2005
  • CHAS accredited

Our process

The first thing on site is a walk round with your contact, 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. For a job in Maidenbower, the main thing is a clear picture of the work. A fixed quote follows.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Getting the site ready

  • Tell staff and tenants when we’ll be in
  • Have the specification and drawings to hand
  • Share the asbestos register for older buildings
