Washroom sealing for commercial buildings in Send

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. Every resealed washroom carries our 12-month guarantee. We work on urinals and WCs, IPS panels and cubicles and showers, trays and wet room floors, and the usual reasons a site gets in touch are shower tray joints that have opened up and kitchen worktop joints that can’t be kept clean. A specialist sealant contractor works differently from a general builder: on jobs in Send, preparation and product choice get the time they need.

Around Send, washroom work typically comes one building at a time. Photos of each area help us plan the visit and bring the right sealant.

Every job we finish is backed by a 12-month workmanship guarantee, in Send as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Sanitary sealant for Send buildings

Send is about 24 miles from central London, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time.

For a campus such as University of Surrey - Stag Hill Campus, which lies south-west of Send, showers in residences and washrooms in teaching blocks can be programmed around term dates. At a college such as Woking College, 1.4 miles north-west of Send, washroom and kitchen sealant is best renewed in the holidays or in phases during term.

Send is about 3 miles south-east of Woking, in Surrey. We send applicators to Send for washrooms and wet areas, handled exactly as we handle every other area. Send is one of 379 places we cover in Surrey for washrooms and wet areas. Our Reading page has more on work in that area (22 miles or so).

Work on washrooms and wet areas is covered throughout GU23, for business premises of every kind. Buildings on Sandy Lane, Farm Lane and Sandfields are within our area for washrooms and wet areas. Just outside Send, we also work in Send Marsh (1 mile east), Burntcommon (1 mile east), Sutton Green (1 mile south-west), Mayford (2 miles west) and Pyle Hill (2 miles west). Further afield, our area takes in Guildford (3 miles south-west), Woking (3 miles north-west), Camberley (9 miles west), Epsom (12 miles east), Farnham (13 miles south-west) and Ewell (13 miles east).

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Which sealant the job calls for
  • Distance, for remote addresses
  • How much there is to seal
  • The site’s rules and procedures

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • Anything awkward about access or site hours
  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around
  • The asbestos register, for older buildings

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email drawings and photos.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. Several jobs near Send can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Preparing the site

  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed

Related advice

Leave it or put it right?

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • Specification-led, product-correct work
  • Fully insured, including public liability cover
  • Colours chosen to suit frames, cladding or finishes where possible
  • One contact handling all your sites

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Questions about Send

Would you work within a site like Woking Community Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Send outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

How do I request a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or send photos by email. Include photos or drawings if you have them.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

Is old silicone taken out first?

The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Looking after the joints

Regular inspection catches problems early. In particular:

  • Note failing joints building by building
  • Squeegee showers and trays after busy periods
  • Clean sealant with gentle products and a soft cloth
  • Share your site rules when you send details

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Signs you need washroom sealing in Send

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They aren’t made for constant wetting, and they stain, crack or wash out.

Common reasons buildings call us in:

  • Washrooms that look worn because of the sealant
  • Failed sealant behind washroom basins
  • Black mould inside silicone joints that cleaning can’t shift
  • A new bead over an old one coming away

At a hospital like Woking Community Hospital (2.1 miles north-west of Send), patient and staff washrooms are best done in short phases agreed with the ward.
