What Our Clients Say

Project Questions

Common Questions

Common questions about our materials, pricing, and renovation process.

What materials do you use on your projects?

We work with materials we would use in our own homes. That means quartz countertops, quality cabinetry from trusted suppliers, Level 4 drywall finish, and quality flooring. Every material is specified in your proposal before work starts — no surprises.

How much does a typical renovation cost?

Every project is different. A kitchen remodel typically starts around $40,000. A full main floor or whole home renovation runs $80,000 and up. We provide a detailed, fixed-price proposal before any work begins — so you know exactly what you are getting.

How long does a renovation take?

Timelines depend on scope. A bathroom runs 2 to 3 weeks. A kitchen or basement is typically 4 to 8 weeks. A whole home renovation can take 3 to 4 months. You get a clear schedule before we start and daily updates throughout.

Do you handle permits and inspections?

Yes. We pull all required building permits and coordinate inspections directly with the municipality. You do not have to chase anyone — we handle it start to finish.
