What problems we deal with in this job

Look out for loose tiles, leaks near doors and flaking on the edge.

An accurate quote describes which areas will be inspected and which could hide damage that is not yet visible. At Build Ararat we don't promise a permanent repair without knowing the cause and the condition of the materials.

What we check before proposing the work

We check continuity under the paving, falls, drip edges, parapets and junctions with railings.

For a first enquiry we recommend sending photos from different angles, the town, the approximate number of floors and the history of the problem. This information helps us prepare the visit, but photos cannot certify the condition of a facade or the safety of its anchors.

Waterproofing

How it can be solved

The repair may combine waterproofing the horizontal surface, compatible seals, flashings and repairing damage to the edge where needed.

Tools, products and the access system are chosen according to the substrate and the conditions of the job. Rope access, suspended scaffolding, tube scaffolding or a platform can be used where appropriate; no technique is universally better than the others.

What can go wrong if only the appearance is fixed

There's no point repairing only the edge if water is still getting in from the floor.

On exterior elements we also need to check how water drains away, how the joints behave and what maintenance the finish will need. Preparation and details often determine whether a stain, a crack or a flaking layer comes back.

How the quote for balcony waterproofing is prepared

There is no single responsible rate for every building. For this job the key factors are: condition of the substrate; preparation and protection of third parties; the chosen material and its thickness; waste removal and restoration of finishes. To compare proposals, it helps to list materials, labour, safety measures, access equipment and exclusions separately. See how to request a detailed quote.

Frequently asked questions

Can I keep the current paving?

It depends on its stability and the system chosen.

Do the railings make a difference?

Yes; their fixings can create entry points for water.
