DIY balcony waterproofing without removing tiles

We’re so lucky to have beautiful weather in Australia which means we spend a lot of time outdoors. A tiled balcony is a fantastic place to sit for meals, to read, have a beer or a glass of wine or just to soak up the rays. Unfortunately, tiled balconies can be afflicted with leaks. Your first thought is probably “Oh no! That means we’re going to have to rip up the tiles to fix it!” Well, not necessarily. DIY balcony waterproofing without removing tiles is possible … but once you read this article, you may decide to call in the professionals.

Symptoms of a leaky balcony

Leaking balcony repairs are usually necessary when the balcony tile waterproofing hasn’t been done correctly in the first place. Or it could simply be a case of wear and tear in an ageing building. Have you noticed any of the following signs of water leaks on your tiled outdoor or rooftop area?

  • Cracked or missing grout
  • Splitting, cracked or peeling paint
  • Discoloured or stained tiles and grout
  • Loose tiles
  • A hollow sound when you walk over a tile
  • Growth of mould or mildew
  • Weakened or loose structural posts or railings
  • Water ‘ponding’ in areas

Where to start with waterproofing balcony

If you are experiencing any of these conditions, you need to get help as soon as possible. Allowing a leak to spread will only worsen the problem and make it harder – and more expensive – to fix. A balcony tile leak repair is the place to start. There’s really no point scrubbing the stains or re-grouting the tiles until the leak is found.

We use a specialised device to detect the leak. Our moisture detection scanning equipment locates the site so we can perform non-destructive repairs and then conduct remedial waterproofing services. This is done without removing tiles, which will no doubt come as a relief to you.

You’ll also be pleased to know that we don’t just leave it at that either. Your balcony waterproofing repair also involves restoring the area so that it looks as good as new. All the old, worn and damaged grout will be removed and the whole surface will be given a thorough clean before re-grouting balcony floor tiles with a new layer of EPG epoxy grout. We use a high quality polyurethane to finish all the internal joints for maximum sealing, to keep water out for good!

Finally, we apply two coats of clear waterproofing membrane and a clear penetrating sealer which will keep your tiles and grout stain resistant for up to 10 years or we’ll return and treat the surface again at no charge.

DIY balcony waterproofing without removing tiles – yes or no?

Staying home is the new going out! As such, we want our homes to be maintained in a condition that’s enjoyable, practical, safe and convenient. But what happens when you have a leaking tiled balcony? Does your mind instantly go to the nightmare of removing tiles to find the leak? What if we told you that balcony waterproofing repair can be done without removing any tiles?

Where are balconies leaking?

In our day to day work, we’re seeing leaky balconies in old and new buildings, two-story homes, high-rise apartments, office towers and everything in between. Sometimes the leak impacts on a room below the balcony and other times, it’s a chain reaction, meaning that if the 15th floor’s balcony is leaking, all those below it will, in time, suffer. Whatever the situation, leaking balcony repairs must be done as soon as possible to halt any damage spreading.

DIY waterproofing balcony

If you’re looking to do some DIY balcony tile waterproofing at home, you should really only consider this an option if you have some experience in this kind of specialised task. First and foremost, it involves leak detection moisture metres that permit balcony waterproofing without removing tiles. And isn’t that the biggest headache of the job? Once you start removing tiles, you then have to find the exact same tiles to get your balcony back to normal. Even if you do find the same ones, they’ll be from a different batch so matching them with the old ones will be very difficult and the end result will be disappointing.

Waterproofing your balcony yourself presents the following problems:

  • Purchasing expensive products and having waste left over.
  • Not having the skills or experience to produce a fully remediated result.
  • Spending a great deal of time on a task that can take several days in inexperienced hands.
  • Having to remove, purchase and replace tiles because you haven’t been able to detect the leak.

Why you should choose professional remedial waterproofing services


As professionals in this very task, we’re out there doing remedial waterproofing and re-grouting balcony floor tiles on a daily basis. We can get the job done in around half a day, depending on the area size of the problem.

We remove all old and ineffective grout and give the area a deep clean to remove any surface contaminants. We apply a new layer of EPG epoxy grout to restore all the joins between tiles back to new. Next, we use a high-quality flexible polyurethane to ensure maximum sealing and finish with two coats of our own waterproofing membrane product, ColourSeal, which guarantees a watertight seal for 15 years.

Finally, the whole area is given a coating of our clear penetrating sealing service which promises a stain-free surface for up to 10 years or we’ll retreat the surface for free.

There are many jobs you can DIY around the house and achieve a spectacular result. Before starting on waterproofing your leaking balcony, ask yourself if you really have the tools, the patience, the experience, the skills and the time to tackle it. It could cost you a whole lot more in the long run.
