We Analyzed 50 Tile Projects in Montreal — Here’s What Homeowners Regret the Most

Most tile projects don’t fail because of the tile.They fail because of decisions made long before installation even begins.

After working on dozens of tile installations across Montreal, from small bathroom upgrades to full-scale renovations, we started noticing something interesting.

The biggest regrets homeowners had weren’t about color, style, or trends.

They were about what went wrong behind the scenes.

So we took a step back and analyzed over 50 real projects to identify the patterns. What mistakes kept showing up? What would people do differently if they could go back?

If you're planning a renovation, this article will give you a clear advantage, because most of these mistakes are preventable, but only if you know what to look for.

Regret #1 — “We chose the cheapest quote… and paid for it later”

At first glance, tile installation can seem straightforward.Many homeowners assume that one contractor is essentially the same as another, just at a different price.

That assumption is where things start to go wrong.

In lower-cost projects, we often see shortcuts like:

• minimal surface preparation

• uneven leveling

• rushed installation timelines

These decisions don’t always show immediately. But a few months later, the signs begin:cracked tiles, hollow sounds when you walk, grout lines breaking down.

What seemed like a “saving” quickly turns into a repair.

What most people don’t realize: You’re not paying for tile installation, you’re paying for how long it will last.

Regret #2 — “No one told us what was under the tile mattered”

This is, without exaggeration, one of the most critical (and ignored) parts of any tile project.

The subfloor.

If the base isn’t properly prepared, even the most expensive tiles will fail.

We’ve seen perfectly beautiful installations deteriorate within a year simply because:

• the surface wasn’t properly leveled

• the structure wasn’t stable

• moisture protection was incomplete

From the outside, everything looked perfect.Underneath, it was already compromised.

Reality: Tile doesn’t fail from the top, it fails from underneath.

Regret #3 — “We chose what looked good, not what worked”

Design matters. But function matters more.

One of the most common patterns we found was homeowners choosing tiles purely based on aesthetics, without understanding how they perform in real life.

For example:

• glossy tiles in bathrooms that become dangerously slippery

• materials that absorb moisture in high-humidity spaces

• finishes that show every stain, footprint, or scratch

These aren’t design mistakes, they’re context mistakes.

The difference:A good tile looks beautiful.The right tile works for your lifestyle.

Regret #4 — “Something felt off… but we couldn’t explain why”

This is where craftsmanship becomes visible.

Even when the materials are high quality, poor layout planning can ruin the final result.

We’ve seen projects where:

• cuts near edges look rushed or inconsistent

• patterns don’t align properly

• spacing feels visually unbalanced

Nothing is “technically wrong”, but everything feels slightly off.

That’s because tile installation is not just technical. It’s visual precision.

Truth: The difference between average and premium is in the details most people can’t name, but immediately notice.

Regret #5 — “We didn’t think waterproofing was that important”

Until it becomes a problem.

In bathrooms, kitchens, and basements, waterproofing is not a bonus, it’s a foundation.

When it’s done incorrectly (or skipped), the consequences don’t show immediately. But over time, they become expensive:

• hidden moisture buildup

• mold development

• structural damage behind walls or under floors

And by the time you notice it, the repair is no longer simple.

Hard truth: Water damage doesn’t happen suddenly, it builds quietly.

Regret #6 — “We didn’t think long-term”

Many renovation decisions are made in the moment:what looks best now, what feels trendy, what fits the immediate vision.

But a tile project isn’t temporary. It’s something you live with every day.

We’ve seen clients regret:

• trends that feel outdated after a short time

• materials that are difficult to maintain

• finishes that wear faster than expected

Better question to ask: Will I still like this in 5 years, not just today?

What the Best Projects Have in Common

When we looked at the projects homeowners were happiest with, the pattern was clear.

It wasn’t about budget.It wasn’t about luxury materials.

It was about decisions made early, and made correctly.

The most successful projects focused on:

• proper preparation before installation

• choosing materials based on use, not just style

• thoughtful layout planning

• experienced, detail-oriented execution

Everything else followed from there.

Before You Start Your Tile Project

If you take one thing from this article, let it be this:

Most regrets are not about what you see.They’re about what you don’t.

Before moving forward, make sure you have clarity on:

• how the surface will be prepared

• whether the materials fit your space

• how the layout will be executed

• who is responsible for the quality of every step

Because once the tiles are installed, correcting mistakes becomes significantly more expensive.
