Construction mastic in Willington

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

FAQs: Willington

Could you schedule work at a campus like University for the Creative Arts for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

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

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Do you do internal caulk as well as external mastic?

Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. The scope follows your specification.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Is the mastic package guaranteed?

It’s backed by our 12-month guarantee on the workmanship. Protecting sealed areas from following trades helps avoid damage.

How many days will you need on site?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Can you fit around our programme?

Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready, and we will raise anything that holds the work up.

Construction mastic in Willington

Mastic tends to be one of the final packages before handover. Mastic Doctor takes on mastic packages for main contractors and developers on schemes in Willington, following the trades through the building as rooms and elevations become ready. Site teams most often ask us about missed perimeter joints on a new elevation and internal caulk splitting as the building dries out, on window and door perimeters, brick and block movement joints and floor and skirting junctions. For commercial sealant work in Willington, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Building work in places the size of Willington is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Quoting for work in Willington

A fixed quote reflects the actual work. It takes account of:

  • How much existing material needs removing
  • Location, for remote and island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits

Pricing mastic packages depends on how many there are, their condition and the access. Call for a quote.

Details that help us quote

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Your programme or deadline
  • Rough lengths or quantities, or drawings if you have them
  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Construction mastic in Willington: the local picture

Willington lies roughly 33 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. There are several hotels within about 2 miles of Willington. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

Recladding or extending a unit at a site like Park Wood Trading Estate, 0.9 miles to the south of Willington, brings panel joints and frame perimeters into the programme. On a campus such as University for the Creative Arts, which lies north-west of Willington, new teaching buildings and residences are normally built and refurbished around the academic year. When a college such as Kent Police College, 0.7 miles to the south-west of Willington, builds or refurbishes, the mastic package normally has to fit around students and staff.

Willington is about 2 miles south-east of Maidstone, in Kent. We send applicators to Willington for mastic packages, handled exactly as we handle every other area. Across Kent, 931 places are covered, Willington among them. London is covered too, around 33 miles from Willington.

If you need construction mastic in ME15 and ME17, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

If your building is just outside Willington, we cover Shepway (1 mile west), Otham (1 mile south-east), Park Wood (1 mile south), Bearsted (2 miles north-east) and Weavering (2 miles north). Bigger towns within reach include Ashford (15 miles south-east), Sittingbourne (10 miles north-east), Royal Tunbridge Wells (15 miles south-west), Gravesend (15 miles north-west), Tonbridge (13 miles west) and Faversham (15 miles east).

Different surfaces, different methods

Fire-rated sealant where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer; we work to the specification and the manufacturer’s installation guidance.

Kitchens and utility areas

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product.

Keeping the joints sound

Problems stay small when the joints are checked regularly. In particular:

  • Brief the final clean team to avoid blades near sealant
  • Keep product details for future maintenance
  • Bring the mastic contractor in after the last trades are through
  • Use the product the specification names

Any damage after we have finished should go on the snag list right away. Snags can be picked up in a planned close-out visit as agreed in the quote.

External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks, so we plan external work with that in mind.

What happens if it’s left?

Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. We can run snagging as its own phase before handover. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Honest limits

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Oversized gaps that need packing or adjustment by others
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
  • Glazing units that are cracked or misted

If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Surfaces we seal

  • Internal decorators’ caulk
  • Window and door perimeters
  • Sanitary and kitchen joints
  • Brick and block movement joints
  • Floor and skirting junctions
  • Cladding and panel joints

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Several jobs near Willington can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. Drawings, specification and programme come to us.
  2. Quantities are measured and a fixed price returned.
  3. We agree with the site team which areas come first.
  4. Each area is sealed when it’s released.
  5. Joints are prepared, backed and sealed to the specification.
  6. After snagging, the work is handed over under our 12-month guarantee.

Before we start on site

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use
