Mississauga contractors see the same renovation mistakes over and over. Most of them are avoidable — and all of them are expensive to fix after the fact. Here are the seven that cost Mississauga homeowners the most money, frustration, and time on kitchen renovations.
Under-budgeting by 10–20%
Most kitchen renos run over. Always add a 15–20% contingency to your quote.
Skipping the permit
Unpermitted electrical and plumbing work can void home insurance and cause problems at resale.
Choosing the cheapest quote
The lowest bid often reflects missing scope. Always compare line-by-line, not total price.
Ordering cabinets before finalizing layout
Cabinet lead times run 8–14 weeks. Changes after ordering are expensive.
Ignoring ventilation
Proper range hood venting to exterior is code in most provinces — and makes a huge quality-of-life difference.
Cheap countertops in a premium kitchen
Mismatched quality levels look wrong and hurt resale. Match your countertop budget to your cabinet investment.
No written change order process
Scope creep without documentation leads to disputes. Every change should be signed off in writing.
The Bottom Line
Most of these mistakes share a common thread: they're caused by rushing decisions, skipping steps that seem optional, or choosing cost savings in the wrong places. A kitchen renovation starting at $50,000 is a significant investment. Spending an extra $500–$2,000 to do it right protects the other $50K+.
