Renovating your home can be exciting, but it’s easy for even experienced homeowners to make costly mistakes.
Here’s our guide to the top 10 home renovation mistakes and how to avoid them.
1. Skipping the Planning Stage
Mistake: Starting work without a detailed plan.
How to Avoid: Create a clear plan, including design ideas, materials, timelines, and budgets. Include contingencies for unexpected costs. A well-thought-out plan keeps your project on track.
2. Underestimating Costs
Mistake: Budgeting too tightly or ignoring hidden expenses.
How to Avoid: Get multiple quotes from builders, suppliers, and tradespeople. Add at least 10–15% contingency for unexpected costs like structural issues or delays.
3. Choosing the Wrong Builder
Mistake: Hiring without checking credentials, references, or past work.
How to Avoid: Vet your builder carefully—check insurance, qualifications, trade association membership, and client references. Use trusted platforms like The Association of Master Tradesmen to find vetted professionals.
4. Ignoring Building Regulations
Mistake: Skipping permits or failing inspections.
How to Avoid: Check planning permission and building regulations for your project. This avoids fines, delays, or even having to undo work.
5. Poor Communication with Your Builder
Mistake: Not discussing expectations or updates.
How to Avoid: Maintain regular communication. Hold weekly check-ins, document decisions, and confirm changes in writing to prevent misunderstandings.
6. Compromising on Quality to Save Money
Mistake: Opting for cheaper materials or cutting corners.
How to Avoid: Invest in quality materials and workmanship. Inexpensive shortcuts can cost more in repairs and reduce the longevity of your renovation.
7. Overlooking Structural or Maintenance Issues
Mistake: Ignoring plumbing, electrical, or roof problems before starting.
How to Avoid: Conduct thorough inspections and address issues first. Prevents costly delays and ensures your home is safe during renovation.
8. Failing to Plan for Storage and Living Arrangements
Mistake: Not considering how to live in or manage your home during renovations.
How to Avoid: Plan temporary storage for furniture and belongings. If necessary, arrange alternative accommodation for major projects to avoid stress and damage.
9. Making Frequent Design Changes
Mistake: Changing the design mid-project.
How to Avoid: Finalise plans and layouts before work starts. Minor tweaks are normal, but constant changes increase costs, timelines, and frustration.
10. Neglecting Aftercare and Warranties
Mistake: Assuming the work is done once the builder leaves.
How to Avoid: Ensure your builder provides warranties on workmanship and materials. Schedule snagging inspections and keep contact details handy for any post-renovation issues.
