Washroom sealing in Gay Street

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

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

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

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a morning or so for a small washroom, longer where showers and changing rooms are included. Smaller jobs around Gay Street can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  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.

Before we start on site

  • Tell us which areas need to stay in use
  • Confirm the product named in the specification
  • Make sure the joints can be reached

Quotes

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

FAQs: Gay Street

Is Gay Street too far out for you?

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

Can you work around term dates at a campus such as Brinsbury College?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can you quote from photos?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.

Do you have public liability insurance?

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

What guarantee comes with washroom resealing?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Cost factors for washrooms and wet areas

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • Location, for remote and island sites
  • Working within restricted access windows
  • Backing rod, priming and other preparation

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • What the building is and how it’s used
  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older
  • Any dates the work must fit around

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

When something else is needed

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Water from plumbing, not from a joint
  • Swollen or delaminated boards behind panels or vanity tops
  • Loose panels, vanity units or tiles, which need fixing first

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

What we seal

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

Do you need washroom sealing in Gay Street?

A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old so it peels away quickly.

Most enquiries start with one or more of the following:

  • Split or peeling sealant at shower trays
  • Kitchen worktop joints that can’t be kept clean
  • Mould spotting along silicone joints
  • A new bead over an old one coming away

If you manage an office at a site such as Broomers Hill Business Park, 1.4 miles west of Gay Street, the washrooms and tea points can be done a floor at a time.

What to look for in a quote

  • Will RAMS and insurance details be available?
  • Health and safety accreditation such as CHAS
  • Will failed sealant be removed rather than covered?
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

Surface by surface

Wet-room floors and floor-to-wall joints

Wet floors are common in accessible showers and changing rooms so the edges are checked carefully.

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.
