Home Renovation & Construction FAQ
How long does a typical renovation take?
Walk-up basement conversion: 8-14 weeks. Basement finish: 6-10 weeks. Addition: 12-24 weeks. Whole-home reno: 4-9 months. We give a written timeline with milestones.
Do I need permits?
Almost always. Walk-up basement: yes (basement walkout permit + plumbing if adding kitchen). Addition: yes (building permit + zoning). Basement finish: yes if adding bathroom or kitchen. We handle every permit.
Can I live in the house during renovation?
For basement work and additions: yes, with dust control. For whole-home renos: usually no — most clients move out for the duration.
Will you coordinate plumbing and electrical?
Yes — we have licensed plumber and electrician partners and coordinate their work as part of the project. You’re not chasing subs.
Do you offer financing?
Yes — financing partners for projects over $25,000 with installment plans up to 60 months. Ask when you request your quote.
How do progress payments work?
Typically: 10% deposit, then milestone payments at framing, rough-in, drywall, and final. Written into the contract — you only pay as each milestone passes inspection.
