Construction mastic across Kenardington

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

What sets the cost

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

  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants
  • Travel to remote or island sites
  • Whether old sealant has to be cut out first

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • Any dates the work must fit around
  • The site address and postcode
  • Clear photographs of the problem areas
  • The type of building and who uses it

Construction mastic for commercial buildings in Kenardington

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 on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. We work on internal decorators’ caulk, window and door perimeters and floor and skirting junctions, and the failures we are asked to look at most are snag items on joints that need redoing before handover and new external sealant already peeling away. Searching for sealant specialists in Kenardington? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Conversions of older rural buildings near smaller places such as Kenardington bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

On site: what to expect

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. If others near Kenardington need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First we take quantities off the drawings and read through the specification.
  2. We return a fixed quote that ties the mastic package to your programme.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. Areas are sealed plot by plot or floor by floor as the trades hand them over.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. We close out snagging and hand over with a 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Point out parking and an unloading spot
  • Send your site hours and access windows

Common problems we fix in Kenardington

Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with. Better to raise it at the start than seal a joint that’s bound to fail.

Most enquiries start with something like this:

  • Oversized or tapered gaps around new frames
  • Bath and shower joints scraped during the final clean
  • Window and door perimeters that won’t pass inspection
  • New external sealant already peeling away

Recladding or extending a unit at a site like Meadow View Business Park (2.7 miles east of Kenardington) brings panel joints and frame perimeters into the programme.

Comparing quotes

  • Will CSCS-carded applicators be on site?
  • What the guarantee covers, and for how long
  • The named product and why it was chosen
  • Whether old or failed sealant will be cut out, not overlaid

Questions to ask before you appoint anyone

What the job involves on each surface

Window and door perimeters

Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. The specification decides which, and colour-matched products can be used where the frame is on show.

Fire-rated sealant where specified

Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services so we will flag where the detail needs something different. Tell us what records you need and we will confirm with the quote.

Building owners, agents and FMs in Kenardington

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Approving fire stopping as compliant
  • Faulty frames rather than failed sealant
  • Rework caused by others damaging completed areas

If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think before you book.

Where we work in Kenardington

  • Sanitary and kitchen joints

  • Window and door perimeters
  • Floor and skirting junctions

Facades, frames and programmes in Kenardington

Kenardington is about 50 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Kenardington sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.

On any site in or around Kenardington, the mastic follows the specification and the programme.

Kenardington is about 6 miles south-west of Ashford, in Kent. Businesses, contractors and managing agents in Kenardington can call on us for mastic packages. 931 places across Kent fall within our area, including Kenardington. For work in that direction, see our Brighton page (44 miles or so).

Kenardington: questions and answers

Is a smaller place like Kenardington outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can you work to our programme on a site in or near Kenardington?

Yes. The mastic is planned around your key stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you take on mastic snagging only?

Yes. We clear snags by redoing joints rather than patching them, working to your handover date.

What happens if the weather stops external sealing?

Outside, the joint has to be dry and the temperature within the product’s limits. Damp, frost or condensation on frames can stop work so we typically switch to internal work when that happens.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
