About our mastic sealing in Canonbie

We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. Site teams most often ask us about mastic failing across several blocks on an estate and damp patches beside frames, on communal kitchens and washrooms, balcony and threshold joints and communal entrances and stairwells. Whoever orders the work in Canonbie, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

For buildings around Canonbie, we group the work to keep travel and visits down. Send addresses and photos for a quote covering the batch.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Plan resealing building by building rather than complaint by complaint
  • Check the asbestos register before any old mastic is disturbed
  • Reduce knocks to communal area joints
  • Include mastic in your cyclical inspections

Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.

Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Misted or failed double-glazed units
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Materials that need asbestos testing before work

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

What we seal

  • Shopfronts below residential blocks
  • Communal entrances and stairwells
  • Balcony and threshold joints
  • External wall and movement joints
  • Communal kitchens and washrooms
  • Window and door perimeters on blocks

Cost factors for mastic joints

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

  • The total length or number of joints
  • The product specified
  • Whether the work must be split into stages
  • Induction, permit and paperwork requirements

Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

Sending details for a quote

We can often quote from photos and a few details. It helps to include:

  • Specification clauses that apply
  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • Photos of the joints, close up and from further back

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email a schedule or drawings with what you know.

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building near Canonbie, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

What we need from you

  • Flag any permit to work we will need
  • Tell staff and tenants when we will be in
  • Share the asbestos register for older buildings

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

Should maintenance staff do it?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Canonbie: questions and answers

Is Canonbie too small for you to travel to?

Not at all. Canonbie is within our area. We cover the whole of Scotland. Good photos up front let us bring everything on the first visit.

Do you take on block-wide or estate-wide mastic work in Canonbie?

Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Is mastic sealing guaranteed?

A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
