"How much will my remodel cost?" is probably top of mind after you've been considering your dream kitchen remodel.
When taking one of the first steps of determining the budget for your new kitchen, understanding the average costs is a great starting point. On average a Washington, D.C. kitchen remodel cost (without changing the floor plan) can range $75,000 to $150,000, for a mid-range remodel cost. A high end kitchen remodel cost is more likely to run between $150,000 to $250,000. The difference in these always falls on quality and longevity; a high-end material and finish always upholds the best and usually the longest.
Your personal design selections will greatly impact the cost. When it comes to remodeling there is no one size fits all.
There are three main areas that impact your kitchen remodel cost. These include the size of project, infrastructure, and fixtures/finishes.

Absolutely. We offer bathroom remodeling for everything from compact powder rooms to luxury spa-like master suites. For inspiration, browse our blog posts on walk-in shower ideas, bathroom lighting, or modern bathroom decoration.

This covers Bethesda, North Bethesda, Chevy Chase, Potomac, Glen Echo, Cabin John, and Silver Spring.
The first step is a complimentary consultation with our team. We’ll discuss your goals, budget, and vision before preparing a tailored design agreement with detailed plans and renderings.
