Mastic sealing in Clockmill

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

When to call us in Clockmill

Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.

What tends to prompt an enquiry:

  • Draught complaints from residents or tenants
  • Window mastic that has split and shrunk
  • Estate-wide sealant that is simply worn out
  • Leaks at window and door perimeters

Schools and community buildings such as Berwickshire High School need frame and external mastic kept sound like any building.

Comparing quotes

  • How the existing material will be dealt with
  • How long is the guarantee, and what does it include?
  • How the joint faces will be prepared and primed
  • The named product and why it was chosen

Our contractor checklist

Mastic sealing for commercial buildings in Clockmill

Across Clockmill and the rest of the Scottish Borders, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. Most enquiries involve brittle perimeter mastic across a building and mastic failing across several blocks on an estate, on communal entrances and stairwells, external wall and movement joints and window and door perimeters on blocks. For commercial sealant work in Clockmill, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around Clockmill, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Related advice

Maintenance after handover

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

  • Protect low-level joints in entrances
  • List the paperwork your organisation requires when you send details
  • Keep a record of when each building was resealed
  • Prioritise elevations facing the weather

Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

Surface by surface

Planned maintenance

We can work into your cyclical maintenance plan on a timetable you set.

External movement joints

Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.

Building owners, agents and FMs in Clockmill

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

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.

What affects the price in Clockmill

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Backing rod, priming and other preparation
  • Specialist products, such as fire-rated or hygienic sealants
  • Travel to remote or island sites
  • How much existing material needs removing

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • The site address and postcode
  • Your programme or deadline
  • Whether the building will be occupied during the work
  • Access details, including height

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Questions we’re asked in Clockmill

Is Clockmill too small for you to travel to?

Not at all. Clockmill is within our area. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.

Can one quote cover a number of our buildings near Clockmill?

Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Can you take on resealing for a block portfolio?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

Is asbestos a concern with old mastic?

Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
