Q: What is the hardest room to renovate?

• <div><p>While bathrooms and kitchens are nearly equal in terms of renovation difficulty, kitchens are the most challenging.

Q: Do general contractors require a down payment and what is the typical payment schedule?

• <div><p>Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract.

Q: Do I need rebar on a basement floor?

• <div><p>Rebar is an essential part of reinforcing a basement floor, as not having it can impact its structural integrity.

Not including rebar could lead to an unstable floor, so don&rsquo;t skip it!</p></div>

Q: How much does it cost to make bigger windows in a basement?

• <div><p>Making a window in a basement larger costs an average of $4,200.

"Amanda was really very good! At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it. It was very clear that she knew her business and she gave me several ideas that I had not even thought about. I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!
