About our washroom sealing in Forest Green

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 showers, trays and wet room floors, and what we are called in for most is split or peeling sealant at shower trays and sealant stained black around basins and showers. A specialist sealant contractor works differently from a general builder: in Forest Green, that means joint design, primers and backing rod as standard.

In and around smaller places like Forest Green, 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.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Do you need washroom sealing in Forest Green?

Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We check for that first and tell you if another trade is needed.

If one of these sounds familiar, it’s time for a closer look:

  • Failed sealant in a tea point or staff kitchen
  • Gaps where vanity tops meet the wall
  • Washrooms that look worn because of the sealant
  • Mould spotting along silicone joints

Around Forest Green, washroom joints are resealed by removing the old silicone completely and laying anti-mould sanitary silicone on dry surfaces.

Comparing quotes

  • What site paperwork they can supply
  • The terms of the workmanship guarantee
  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?

Choosing a commercial sealant contractor

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

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. A poor seal in places like these tends to cost more to put right later.

Wet areas in Forest Green’s workplaces

Forest Green lies roughly 27 miles out from central London, within the office belt around the capital. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

For a hall at a building such as Holy Trinity, resealing the kitchen and toilets can be fitted between bookings.

Cost factors for washrooms and wet areas

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

  • How accessible the joints are
  • Whether old sealant has to be cut out first
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • Access details, including height
  • Any dates the work must fit around
  • The asbestos register, for older buildings
  • Approximate linear metres or a joint schedule

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email drawings and photos.

Different surfaces, different methods

Showers and trays

A tray that rocks or has cracked won’t be fixed by sealant and we flag that beforehand.

Urinals and WC pans

Floor joints around WC pans are often forgotten. They are checked with everything else.

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Forest Green are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

What we need from you

  • Confirm the product named in the specification
  • Point out any areas we must not close
  • Make sure the joints can be reached

Questions we are asked in Forest Green

Do we have to close all our washrooms in Forest Green for resealing?

Typically 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.

Is Forest Green 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.

Can you reseal washrooms in healthcare buildings?

Yes. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can weather delay the job?

It can, for external work. 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.

Is there a guarantee on the work?

There is a 12-month guarantee on our workmanship, and we carry public liability insurance.
