Frequently Asked Questions
How to Budget a Renovation
Why Renovation Costs Vary So Much
Renovation costs depend on four main factors: location, quality of materials, scope of work, and property condition. Our estimator accounts for the first three and adds a contingency buffer for the fourth.
Budget vs Standard vs Premium
Budget renovations use basic materials and focus on functionality. Standard renovations balance aesthetics and cost. Premium renovations use high-end materials and custom craftsmanship.
The Most Expensive Rooms to Renovate
Kitchens and bathrooms are the most expensive because they involve plumbing, electrical, and specialized fixtures. However, they also add the most value: kitchens return 60-80% and bathrooms 50-70%.
Tips to Keep Costs Under Control
Get at least 3 quotes. Define scope clearly before starting. Keep existing layout when possible. Buy materials yourself when possible. Always keep 10-20% as contingency.
