Construction mastic for Selling sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Construction mastic for commercial buildings in Selling

We work to the specification and the programme. Where the specification names a product, we use it. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. We work on internal decorators’ caulk, floor and skirting junctions and sanitary and kitchen joints, and the usual reasons a site gets in touch are window and door perimeters that won’t pass inspection and frame gaps too wide for sealant alone. A single leaking joint is often how a building in Selling first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Sites around smaller places like Selling can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

What happens if it’s left?

A quick bead over a damaged joint can get an area past inspection. Sealant can’t grip a contaminated or existing bead, and the defect comes back after handover. Damaged joints are removed and resealed from clean faces. One visit to deal with every failing joint makes more sense than several trips to a place like Selling. Photos of every joint help us quote for the whole job.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Why appoint us

  • Specification-led, product-correct work
  • 12 months’ guarantee on every job
  • Old sealant cut out, never sealed over
  • Colour options checked against the specified product

Questions we are asked in Selling

Can the mastic package for our job in Selling follow the site programme?

Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Which documents can you supply for work in Selling?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

What do you charge?

Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or send details through our quote form with a description of the work.

Can staff carry on working while you’re here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit typically takes a day or two on a small fit-out and several weeks on a large multi-storey package. For bigger or phased jobs, we’ll set out a timescale with the quote.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Mastic packages on Selling sites

At about 47 miles from central London, Selling is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.

School extensions, at buildings such as Selling Church of England Primary School, usually run to the summer holidays, mastic included.

Selling is about 3 miles south-east of Faversham, in Kent. Across the ME13 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Selling is one of 931 places in Kent on our list. There’s a separate page for London, roughly 47 miles from Selling.

Commercial sites across ME13 are covered for mastic packages. If your site is on Selling Road, Selling Court and Vicarage Lane or close by, we can quote for mastic packages. We also cover Perrywood (1 mile south), Hogben's Hill (1 mile west), Gushmere (1 mile north), Neames Forstal (1 mile east) and Crouch (1 mile north-east) for mastic packages. A short drive away, we cover Ashford (9 miles south), Canterbury (7 miles east), Sittingbourne (10 miles north-west), Whitstable (7 miles north-east), Faversham (3 miles north-west) and Herne Bay (11 miles north-east).

Do you need construction mastic in Selling?

Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage.

Clients usually get in touch after noticing something like this:

  • Frame perimeters left unsealed or poorly sealed
  • Failed sealant in an existing building being refurbished
  • External joints sealed in damp or cold conditions that are now failing
  • Frame gaps too wide for sealant alone

Older buildings in the area around Selling, such as Belmont House and Gardens, 3.4 miles to the west of Selling, need care when sealed: the product has to suit soft or historic materials.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • Their public liability cover
  • Their plan for phasing and protecting the area
  • Whether old or failed sealant will be cut out, not overlaid

Choosing a commercial sealant contractor

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Selling need work, visits can be combined. A fixed quote is given before anything starts.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. The sequence is agreed with the site manager.
  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

  • Tell us which areas need to stay in use
  • Send your site hours and access windows
  • Flag any permit to work we will need

Advice

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Joints damaged after sign-off by following trades
  • Deciding which fire-stopping product a penetration needs

If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Where we work in Selling

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

What sets the cost

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

  • Specialist products, such as fire-rated or hygienic sealants
  • Whether the work must be split into stages
  • Backing rod, priming and other preparation
  • Distance, for remote addresses

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • The product your specification calls for
  • Approximate linear metres or a joint schedule
  • The type of building and who uses it
  • Your programme or deadline

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or use the quote form.
