Construction mastic across Badlesmere

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How the quote is worked out

These are the things that shape the price:

  • Access and working height
  • The total length or number of joints
  • Travel to remote or island sites
  • Phasing around occupants

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.

Before you send an enquiry

However big the job, these details speed things up:

  • The product your specification calls for
  • Access details, including height
  • Your programme or deadline
  • Photos of the joints, close up and from further back

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Construction mastic in Badlesmere, done properly

Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Badlesmere, send drawings and the specification through our quote form. We work on cladding and panel joints, floor and skirting junctions and window and door perimeters, and the usual reasons a site gets in touch are different trades sealing to different standards and perimeter gaps outside the sealant’s range. Facilities teams, main contractors and managing agents in Badlesmere tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Badlesmere, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Surface by surface

External facade and movement joints

Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.

Snagging before handover

Snagging is often the final mastic stage. Snags are cleared room by room, cutting out damaged joints and resealing them properly.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Badlesmere, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. Final snagging is completed and the 12-month guarantee applies.

What we need from you

  • Confirm the product named in the specification
  • Flag any permit to work we’ll need
  • Move anything stored against the joints

Advice

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Sites and facades in and around Badlesmere

The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Badlesmere lies roughly 45 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.

Projects at schools like Sheldwich Primary School work to term dates, so mastic is programmed tightly. With historic properties like Belmont House and Gardens (to the north-west of Badlesmere) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Badlesmere is about 4 miles south of Preston, in Kent. We send applicators to Badlesmere for mastic packages. Badlesmere is one of 931 places in Kent on our list for mastic packages. London is covered too, around 45 miles from Badlesmere.

Your questions answered

What paperwork can you provide for a job in Badlesmere?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Is Badlesmere too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

What happens if the weather stops external sealing?

Conditions have to suit the product before external work starts. Sealing in poor conditions risks adhesion failure, so we wait rather than redo work.

Are you CHAS accredited?

We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We’re also fully insured, with five million pounds of public liability cover.

Can you clear a mastic snag list before handover?

Yes, we can. Share the list and photographs, and a fixed quote follows.

What happens if it’s left?

A quick bead over a damaged joint can get an area past inspection, but it won’t last. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. Damaged joints are removed and resealed from clean faces. Converted and older buildings near places like Badlesmere tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Why appoint us

  • Workmanship guaranteed for 12 months
  • Standard and matched colours in many product ranges
  • Colour agreed before work starts
  • Joints cleaned back to sound surfaces

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Share drawings and the specification as soon as possible
  • Keep scrapers and abrasive pads off new beads
  • Note which sealant went where at handover
  • Stick to the specified sealant rather than a generic substitute

Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.

Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short and keeps handover on track.
