After completing more than 800 renovation projects across Dubai, we have seen every mistake in the book. Some cost homeowners a few thousand dirhams. Others cost them their entire deposit and months of wasted time. Here are the seven most common — and how to protect yourself.

1. Choosing the Cheapest Quote

The cheapest quote is almost never the cheapest project. Low-ball contractors win jobs by underquoting, then pile on variations once work begins. They use vague terms like "allowances" instead of specifying exact materials. By the halfway point, the "cheap" contractor costs more than the mid-range one would have from the start.

What to do instead: Compare quotes line-by-line. Every material should be named and priced. If a quote says "tiles — allowance AED 45/sqm" instead of naming the exact tile, that is a red flag.

2. Not Getting a NOC Before Starting Work

Every gated community in Dubai requires a No Objection Certificate before renovation work begins. Palm Jumeirah (Nakheel), Arabian Ranches (Emaar), and Emirates Hills each have their own process. Starting work without a NOC can result in fines, work stoppages, and even blacklisting.

What to do instead: Ask your contractor to handle the NOC as part of the project scope. A professional contractor includes this as standard — it should not be an "extra."

3. Skipping the Design Phase

Jumping straight to construction without a finalised design leads to mid-project changes. Moving a light fitting costs AED 200 on a drawing. Moving it after the ceiling is plastered costs AED 2,000. Every design change during construction multiplies in cost.

What to do instead: Invest 2-3 weeks in design finalisation. Lock in every material, fixture position, and finish before demolition begins. Our team provides 3D renders so you can see the result before a single tile is laid.

4. Paying Too Much Upfront

A contractor who asks for 50% or more upfront is a risk. If they disappear — and this happens in Dubai more than you think — your money goes with them. There is almost no legal recourse that recovers the full amount quickly.

What to do instead: Use milestone-based payments. A typical structure: 10-15% mobilisation, then payments tied to completion of specific stages (demolition, rough works, tiling, joinery, handover). You should never be financially ahead of the work completed.

5. Not Checking if the Contractor Uses Subcontractors

Many Dubai renovation companies are actually project management firms. They win the job, then subcontract every trade to different teams. This means no quality control, coordination delays, and no one accountable when something goes wrong.

What to do instead: Ask directly: "Are the workers on my site your employees or subcontractors?" At First Unicorn Group, every tradesperson — from tilers to glass installers — is in-house. One team, one quality standard.

6. Ignoring the Contract Details

Verbal agreements mean nothing when a dispute arises. A proper renovation contract should specify: exact scope of work, material specifications, payment milestones, start and completion dates (with penalty clauses), warranty terms, and variation order procedures.

What to do instead: Read every line. If the contract does not include a fixed completion date with a penalty for overruns, ask why. If there is no warranty clause, walk away.

7. Renovating Room by Room Over Years

Spreading renovations over multiple phases seems financially sensible but usually costs 30-40% more than doing everything at once. Each phase requires separate mobilisation, permits, and disruption. Material prices increase annually. And design continuity suffers.

What to do instead: If budget is a constraint, discuss phased approaches with your contractor upfront. A good contractor can plan the full scope and phase the execution to manage cash flow while keeping the design cohesive and the overall cost lower.
