Balcony Waterproofing and Leak Repairs

Balcony waterproofing lives underneath the tiles, not in the grout between them. That is why resealing the joints never fixes a leaking balcony, and why the damage usually shows up in the room below rather than on the balcony itself.

Our Process

We look at the balcony, the outlet and the ceiling below before quoting, then tell you plainly whether the tiles have to come up or the failure is at one detail.

  1. 1
    Free site inspection.

    We look at the balcony, the room below, and the outlet, and establish whether the membrane has failed or the problem is at a single detail.

  2. 2
    Written quote, honest about scope.

    Localised repair where the membrane is otherwise sound, full replacement where it is not, with preparation and screed work priced separately from the waterproofing.

  3. 3
    The work.

    Torch-on membrane across the slab where the balcony is being redone, liquid rubber at the outlet, upstands, threshold and edges where a sheet cannot conform.

  4. 4
    Follow-up and guarantee.

    Fred phones after the first proper rain to confirm the ceiling below is dry. Written, minimum 2-year guarantee.

Why Choose TurboMax

Balconies are a detail job, and details are where this trade separates. Torch-on and liquid rubber are what we specialise in, Fred quotes and manages every project himself, and his son Thomas runs the second team, so there is an owner on your balcony rather than a subcontractor with a phone number that stops working.

The follow-up is the part clients mention most. Fred phones after the first heavy rain to check the ceiling below is dry, before you have to phone him, and if it is not, we come back at our cost. On a balcony, where the consequence of a failed repair usually lands on somebody else, that matters more than usual.

Written, minimum 2-year guarantee on the workmanship, with extended and 10-year service guarantees available on request.

Frequently Asked Questions

Straight answers, including the ones that talk us out of a bigger job.

What does balcony waterproofing cost?

The main driver is whether the tiles come up. A detail repair at an outlet or a threshold on an otherwise sound membrane is a modest job. Stripping tiles, laying a new membrane and retiling is a considerably bigger one, and bigger again where the screed and falls also need correcting first. Size, access, whether there is a fall to correct, and whether the ceiling below needs repair all move the figure.

Do you have to lift the tiles?

Not always, and we will not do it unless the inspection says the membrane underneath has failed. If the failure is at a single detail, we repair that detail. If the membrane is gone, a surface coating over the top of it buys you a season and then leaks again, and we will tell you that rather than sell you the cheaper version twice.

My balcony pools water after rain. Is that the problem?

It is at least part of it. Standing water sits against the membrane and every joint in it continuously rather than draining away, and it finds weaknesses that moving water never would. Ponding usually means the fall is wrong or the outlet is not doing its job, and both have to be corrected as part of the work rather than covered over.

Water is coming into the flat below mine. Whose responsibility is it?

In a sectional title scheme that depends on the scheme's rules and on whether the balcony is common property or part of your section, and we are not the right people to advise you on it. What we can give you is a clear written report of what we found and what has failed, which is the technical information the scheme will need before anyone can decide anything.

Do you retile afterwards?

We prefer the tiling to be handled as part of the same job, because if someone else lifts and relays tiles over our membrane we cannot stand behind the result, and the guarantee is the point. Ask us when we quote and we will tell you how we would arrange it on your balcony.
