# 10 Costly Renovation Mistakes Ottawa Homeowners Make

After years of working on Ottawa homes, patterns emerge. The same mistakes keep costing homeowners money, time, and frustration. Here are the most expensive ones—and how to avoid them.

## 1. Skipping the Planning Phase

**The mistake:** Rushing to start demo without fully planning the project.

**What happens:**

- Discover structural issues mid-project

- Find unexpected plumbing or electrical

- Realize design doesn't work in practice

- Change orders pile up

- Project takes twice as long

**The fix:**

- Invest in proper design before breaking anything

- Get multiple quotes with detailed scopes

- Have a contingency budget (15-20%)

- Understand what's behind walls before removing them

**Cost of mistake:** $5,000-$20,000+ in changes and delays

## 2. Choosing Contractor on Price Alone

**The mistake:** Taking the lowest bid without evaluating quality.

**What happens:**

- Corners cut to meet low price

- Subpar materials substituted

- Timeline issues and no-shows

- Work needs redoing

- Contractor disappears before finishing

**The fix:**

- Compare 3+ detailed quotes

- Verify references for similar work

- Check insurance and licenses

- Understand HOW they'll achieve the price

- Value isn't always the lowest number

**Cost of mistake:** $10,000-$50,000+ to fix poor work

## 3. Underestimating True Costs

**The mistake:** Budgeting only for the visible work.

**What gets missed:**

- Permit fees

- Design and engineering

- Hidden repairs discovered during work

- Upgraded electrical to support renovation

- Finishing touches (trim, paint, fixtures)

- Temporary living arrangements

- Landscaping restoration

**The fix:**

- Budget for the project plus 20% contingency

- Ask contractor what's NOT included

- Plan for scope creep

- Get quotes for complete scope, not partial

**Cost of mistake:** Running out of money mid-project

## 4. Ignoring Permits

**The mistake:** "It's just interior work, I don't need a permit."

**What happens:**

- Work doesn't meet code

- Problems when selling (disclosure, bank issues)

- Insurance may not cover damage

- City can require removal of work

- Double permit fees as penalty

**The fix:**

- Check with city before starting

- Permit fees are minor compared to consequences

- Proper inspections catch problems early

**Cost of mistake:** $5,000-$30,000+ to bring up to code or remove

## 5. DIY Beyond Your Skill Level

**The mistake:** YouTube makes it look easy.

**Common failures:**

- Electrical that's unsafe

- Plumbing that leaks

- Tile that cracks

- Drywall that looks terrible

- Projects that drag for months

**The fix:**

- Honest assessment of skills

- DIY cosmetic, hire for mechanical/structural

- If you're learning on your house, budget for fixes

- Know when to call professional

**Cost of mistake:** $2,000-$15,000+ to fix failed DIY

## 6. Forgetting About Resale

**The mistake:** Highly personalized renovations that don't appeal to buyers.

**Examples:**

- Converting garage to room (losing parking)

- Wild color schemes

- Removing bedrooms to make larger spaces

- Over-improving for neighborhood

- Trends that will date quickly

**The fix:**

- Consider future buyers even if not selling soon

- Neutral base with personality in changeable elements

- Don't remove features buyers expect

- Research what local buyers want

**Cost of mistake:** Losing $10,000-$50,000+ in resale value

## 7. Poor Contractor Communication

**The mistake:** Assuming everyone's on the same page.

**What happens:**

- Work doesn't match expectations

- "That'll be extra" surprises

- Delays nobody mentioned

- Quality issues discovered too late

- Relationship breaks down

**The fix:**

- Everything important in writing

- Detailed contract with specifications

- Regular check-ins during project

- Clear change order process

- Ask questions before they become problems

**Cost of mistake:** $2,000-$20,000+ in misunderstandings

## 8. Wrong Renovation Timing

**The mistake:** Starting major renovation at the worst time.

**Ottawa-specific timing issues:**

- Exterior work in winter (limited options, higher costs)

- HVAC replacement in peak season (premium pricing)

- Starting before holidays or events

- Beginning before financing secured

**The fix:**

- Plan exterior work for spring/summer/fall

- Book popular trades in off-season

- Account for your family's schedule

- Have financing approved before starting

**Cost of mistake:** 10-30% premium for bad timing

## 9. Neglecting the Boring Stuff

**The mistake:** All budget goes to pretty things, nothing for infrastructure.

**What gets skipped:**

- Electrical panel upgrade (then can't run new appliances)

- Insulation improvements (then heating bills surprise)

- Plumbing upgrades (then pipes fail in 5 years)

- Proper ventilation (then moisture problems appear)

**The fix:**

- Address infrastructure before cosmetics

- Ask what SHOULD be done while walls are open

- Think 10-20 years ahead, not just completion day

**Cost of mistake:** Doing it twice, at higher total cost

## 10. Not Living with the Space First

**The mistake:** Renovating immediately after moving in.

**What happens:**

- Don't understand traffic patterns

- Miss issues that need addressing first

- Realize different priorities after living there

- Waste money on things you'd change anyway

**The fix:**

- Live in house for 6-12 months if possible

- Learn what actually bothers you

- Understand how you use the space

- Emergency repairs only at first

**Cost of mistake:** Renovating the wrong things

## Bonus: Common Ottawa-Specific Mistakes

### Finishing Basement Without Waterproofing

**Mistake:** Beautiful basement that gets destroyed by water.

**Fix:** Address moisture issues before finishing.

### Undersizing HVAC for Addition

**Mistake:** Existing system can't handle new space.

**Fix:** HVAC assessment before addition design finalized.

### Ignoring Ice Dam History

**Mistake:** Renovating attic without addressing heat loss.

**Fix:** Proper air sealing and insulation as part of any roof/attic work.
