Washroom sealing for Sandleford sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

General trades versus a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

About our washroom sealing in Sandleford

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. We work on kitchens and tea points, IPS panels and cubicles and accessible toilets and changing rooms, and what we’re called in for most is sealant stained black around basins and showers and gaps where vanity tops meet the wall. Searching for sealant specialists in Sandleford? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

In and around smaller places like Sandleford, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Sandleford need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  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. Rooms reopen after the cure time.

What we need from you

  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work
  • Make sure the joints can be reached

Questions about Sandleford

Will you plan work around the academic year at somewhere like Newbury College?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a smaller place like Sandleford outside your area?

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.

Can you reseal washrooms in healthcare buildings?

Yes, healthcare and care settings are part of our work. Tell us what records you need and we will confirm with the quote before we start.

Are you fully insured?

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

Will all the toilets be closed at once?

Only the area we’re working in is closed. Each room reopens after the sealant’s cure time and we start the next.

When can showers be used after new sealant?

The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so there are always rooms open.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

How the job changes by surface

Wet-room floors and floor-to-wall joints

We seal the visible joints; we don’t install or repair waterproofing below, and we’ll say if the trouble looks to be beneath the floor.

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. We work to your estates and infection-control requirements and any permits the site uses.

Commercial washrooms in Sandleford

There are a good number of hotels within about 2 miles of Sandleford. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest. Sandleford is about 53 miles from central London. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.

Pupil toilets at schools like The Willows Primary School take heavy daily use, and the holidays give the window to reseal. Colleges such as Newbury College, under half a mile north-west of Sandleford, have toilets, changing rooms and catering kitchens that can be resealed around term dates. Customer toilets and staff facilities at retail sites such as Newbury Retail Park (to the north of Sandleford) need sealant that stays clean under heavy use.

Work for main contractors and building owners

Honest limits

Being straight saves everyone time. Fresh joints won’t solve:

  • Loose panels, vanity units or tiles, which need fixing first
  • A room that stays damp because ventilation isn’t working
  • Swollen or delaminated boards behind panels or vanity tops

Not sure which it is? You can ring 01277 525 020 or use the quote form and we’ll tell you honestly.

Where we work in Sandleford

Quoting for work in Sandleford

The price varies from site to site. Expect it to depend on:

  • Travel to remote or island sites
  • Removal of failed or old sealant
  • The site’s rules and procedures
  • Joint width, depth and condition

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Access details, including height
  • Rough lengths or quantities, or drawings if you have them
  • The type of building and who uses it
  • The postcode of the building

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.
