Facades, frames and programmes in Thanington

At about 52 miles from central London, Thanington is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Thanington sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

Hotel extensions and refits, at places such as Canterbury Hotel, 0.7 miles north-east of Thanington, usually run between busy periods, so the sealing is squeezed into short windows. New units and refits on sites such as Wincheap Industrial Estate, 0.7 miles north-east of Thanington, need their panel and perimeter joints sealed to the specification.

Thanington is about 1 mile south-west of Wincheap, in Kent. Thanington sits inside our coverage and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

About our construction mastic in Thanington

On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. Most enquiries involve failed sealant in an existing building being refurbished and inconsistent sealant finishes from plot to plot, across brick and block movement joints, floor and skirting junctions and sanitary and kitchen joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Thanington, preparation and product choice get the time they need.

On a small site around Thanington, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Advice

Cost factors for mastic packages

Before we quote, we look at:

  • Removal of failed or old sealant
  • Travel to remote or island sites
  • How much there is to seal
  • Specialist products, such as fire-rated or hygienic sealants

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • Access details, including height
  • Rough lengths or quantities, or drawings if you have them

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, speak to us on 01277 525 020 or send photos by email.

Thanington: questions and answers

Will you take on work at estates like Wincheap Industrial Estate, close to Thanington?

Yes. We cover Thanington and the area around it, including industrial estates, business parks and retail parks such as Wincheap Industrial Estate. Photos and a short description are enough for a first look.

Will you plan work around the academic year at somewhere like University of the Creative Arts?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you install fire-rated sealant as part of a package?

Where it’s specified, yes to the tested detail. We will flag if the detail needs a different product.

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Why deal with it now?

Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area usually clears more for less disruption. We can run snagging as its own phase before handover. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

Whether it’s a single area or a whole estate, the same things set the price: 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.

Building owners, agents and FMs in Thanington

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Joints damaged after sign-off by following trades
  • Frame gaps too wide for sealant, which the installer needs to correct

If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Where we work in Thanington

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

Do you need construction mastic in Thanington?

Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge, so gaps outside that range need sorting by the installer first. We flag them early rather than filling them with sealant that won’t last.

It’s worth sending us details if you spot any of the following:

  • Bath and shower joints scraped during the final clean
  • Internal caulk splitting as the building dries out
  • Existing joints on a refurb that need cutting out and resealing
  • External joints sealed in damp or cold conditions that are now failing

New wings at hospitals like Kent and Canterbury Hospital (to the east of Thanington) bring long runs of window and panel joints to seal.
