Questions we are asked in Willen

Do you take on work at healthcare sites like Blakelands Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Do you work in occupied care homes around Willen?

Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you work in Willen?

Yes. Sites across Willen are covered, and the same phone number covers every area.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Do you have public liability insurance?

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

Is it OK to put new silicone on top of the old?

The failed bead is always removed. New silicone won’t stick to the old so a bead over the top fails quickly.

Washroom sealing in Willen

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. We are fully insured. Our workmanship is guaranteed for 12 months. We work on showers, trays and wet room floors, urinals and WCs and accessible toilets and changing rooms, and the usual reasons a site gets in touch are mould spotting along silicone joints and open joints along basins and vanity units. One point of contact handles commercial sealant work in Willen from the first photos to the final walk-round, whether it’s one building or several.

Rural businesses near smaller places such as Willen, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.

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.

Do you need washroom sealing in Willen?

Panels and vanity units move slightly in use and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.

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

  • Stained or open joints at kitchen sinks and worktops
  • Users noticing mouldy joints
  • Sealant laid over old silicone and now peeling
  • Gaps where vanity tops meet the wall

Student showers at universities like University of Bedfordshire Milton Keynes Campus, 2.4 miles south-west of Willen, see more use than most, and their silicone shows it.

What your quote should include

  • How long is the guarantee, and what does it include?
  • Will failed sealant be removed rather than covered?
  • Whether their applicators hold CSCS cards
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

Why it’s worth doing now in Willen

Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. Around Willen, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

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 we will put a fixed figure on it.

Why appoint us

  • Our applicators hold CSCS cards
  • RAL and finish matching where the product range allows
  • One contact handling all your sites
  • Commercial sealant work since 2005

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. Smaller jobs around Willen can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected
  • Have the specification and drawings to hand

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Honest limits

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

  • Fittings that move too much to hold a bead
  • Vanity carcasses that have swollen
  • Failed tanking beneath a wet-room floor or behind tiles

Not sure which it is? You can call 01277 525 020 or email us and we’ll tell you honestly before you book.

Joints and surfaces we work on

  • IPS panels and cubicles
  • Kitchens and tea points

Before we quote, we look at:

  • How much existing material needs removing
  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
