Construction mastic in Eastchurch

Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. If you are dealing with different trades sealing to different standards and mastic snags holding up handover, we can put it right. Searching for sealant specialists in Eastchurch? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Sites around smaller places like Eastchurch can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we will quote to suit.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Protect sealed areas from following trades
  • Record the products used in the O&M file
  • Bring the mastic contractor in after the last trades are through
  • Check frame gaps are within the sealant’s range before sealing

Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades which is why protection after sealing matters.

A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating, and a delay to handover. A check of every frame before decorators start is worth the time.

FAQs: Eastchurch

Can you work on a hospital site such as Sheppey Community Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Our building in Eastchurch is near the coast: does that change the sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Do you offer coloured sealant?

That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How many days will you need on site?

That varies with the scale of the job, but the work normally takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For bigger or phased jobs, we will set out a timescale with the quote.

Do you use the sealant named in the specification?

The specification decides the product. Product standards such as BS EN 15651 are often named in specifications.

Do you have public liability insurance?

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

Do you guarantee new-build sealant work?

Each package is signed off with a 12-month workmanship guarantee. Damage by others after we’ve finished isn’t covered.

Construction mastic around Eastchurch: how the place shapes the job

Eastchurch is within about 2 miles of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Eastchurch is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

For a contractor working at a hospital such as Sheppey Community Hospital, which lies west of Eastchurch, perimeter and facade sealing is planned around patients and deliveries. Recladding or extending a unit at a site like Marshlands Industrial Estate, 2.8 miles west of Eastchurch, brings panel joints and frame perimeters into the programme.

What happens if it’s left?

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility, with the same standard on every plot. Around Eastchurch, 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.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Why us?

  • Our applicators hold CSCS cards
  • Commercial sealant work since 2005
  • Matching to RAL references, product permitting
  • Coloured sealants to suit the setting, where available

What we are called out for in Eastchurch

A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is typically the first to crack. Choosing the right product for each joint reduces that.

Site and facilities staff are often the first to spot these:

  • Sanitary sealant damaged by following trades
  • Missed perimeter joints on a new elevation
  • Different trades sealing to different standards
  • Failed sealant in an existing building being refurbished

Hotel extensions and refits, at places such as The Shurland Hotel, under half a mile north-west of Eastchurch, typically run between busy periods, so the sealing is squeezed into short windows.

Before you book anyone

  • How long is the guarantee, and what does it include?
  • How they’ll work around occupants
  • What level of public liability insurance do they hold?
  • Their pre-qualification and accreditations

Choosing a commercial sealant contractor

What sets the cost

Quotes vary with the job. It mainly depends on:

  • Access and working height
  • How much there is to seal
  • Joint width, depth and condition
  • Location, for remote and island sites

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Specification clauses that apply
  • Drawings or a marked-up plan, if available
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
