Construction mastic for Ashley sites

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

Construction mastic around Ashley: points for this area

Ashley is in the South East, one of the UK’s drier regions. 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. Ashley lies roughly 64 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

New wings at hospitals like Buckland Hospital (to the south of Ashley) bring long runs of window and panel joints to seal. Recladding or extending a unit at a site like Pike Road Industrial Estate (to the north-west of Ashley) brings panel joints and frame perimeters into the programme.

Ashley is about 4 miles north of Dover, in Kent. Looking for construction mastic in Ashley? We can help, as we do across Kent. Ashley is one of 931 places in Kent on our list. Sites around London have their own page, about 64 miles away.

Construction mastic in Ashley

Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal areas can typically carry on while the outside waits. We work on brick and block movement joints, sanitary and kitchen joints and internal decorators’ caulk, and what we are called in for most is sealant knocked or painted over by other trades and failed sealant in an existing building being refurbished. Facilities teams, main contractors and managing agents in Ashley tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a site near Ashley, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.

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

Common questions from Ashley clients

Is hospital work, at somewhere like Buckland Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Ashley off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

What do you charge?

Every job gets its own fixed quote. For yours, phone 01277 525 020 or email drawings and photos.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

What joints do you seal on a new build?

External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. The scope follows your specification.

Can you work to our specification?

Yes. Send it with your enquiry, and we’ll price the work to it.

Can staff carry on working while you are here?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

What sets the cost

Before we quote, we look at:

  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • How much existing material needs removing

There’s no price list, since every building and every scope is different. Call for a quote.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Your programme or deadline
  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area
  • The type of building and who uses it

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email drawings and photos.

Our process

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on 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 a building around Ashley, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We price from the drawings, specification and programme you send.
  2. A fixed quote sets out the scope, the products and the sequence.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. Snags are cleared before handover and completed areas carry our 12-month guarantee.

What we need from you

  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints

Quotes

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or send photos by email.

Advice

After the work

Keep the joints in good shape with a few simple steps:

  • Protect sealed areas from following trades
  • Plan external elevations with the weather in mind
  • Put any product change through the designer first
  • Record the products used in the O&M file

If a joint is damaged after sealing, flag it early. We can return to clear snags before handover.

Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We flag them as soon as we see them.

What we are called out for in Ashley

Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.

Things that usually lead to an enquiry:

  • Oversized or tapered gaps around new frames
  • New external sealant already peeling away
  • Different trades sealing to different standards
  • Sanitary sealant damaged by following trades

Historic houses such as Walmer Castle, 4.3 miles east of Ashley, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

What your quote should include

  • Their public liability cover
  • Their approach to joint depth and backing
  • How they’ll work around occupants
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Designing joint widths or choosing the specification (that sits with the designer)
  • Oversized gaps that need packing or adjustment by others
  • Glazing units that are cracked or misted

If you’re not sure, just ring 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
