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. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.</p></div>

Q: Can you make your basement deeper?

• <div><p>If you don&rsquo;t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less&mdash;between <b>$40,000 and $90,000</b> on average. However, if you&rsquo;re not adding new finished square footage, you won&rsquo;t see much in the way of ROI.</p></div>

Q: Is an extension less expensive than a loft conversion?

• <div><p>Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.</p></div>

Q: Is it less expensive to finish a basement or add an addition?

• <div><p>It&rsquo;s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is <b>$32,000</b> (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.</p></div>

Q: What is considered a finished basement?

• <div><p>A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.</p><p>Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.</p></div>

"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!
