Renovations in New York City come with unique challenges. The primary firm that you choose to work with needs to know how to deal with zoning, permitting, community boards, landmark organizations, and many more entities. If you are in a co-op or a restrictive condo, then they will also have to navigate the policies and practices of the board and management company.
Secondly, New York is full of specialists to handle each of the smaller aspects of the project —electricians, plumbers, carpenters, designers, architects, etc. If you don’t want to get stuck managing these numerous experts yourself, then you need a firm that is experienced in acting as your single point of contact that can organize all of the sub-projects on your behalf.
You also want to work with an experienced company that will be straightforward about estimated costs, will communicate with you throughout the entire process, and that has a good track record of handling projects like yours.
Review Process
We started with reviews on Google, Yelp, and the Better Business Bureau. Looking at the firm’s overall score can give a high level indicator, but it is also important to look at the time period of the reviews. Companies with only recent reviews, or only old reviews are not as informative as those with many years of reviews to demonstrate consistency. It was also helpful to look at issues that customers reported for negative reviews, to get an idea of specific types of projects or situations that the company was not as strong at handling.
The public websites for each of the companies also provided valuable information. This is where each of the firms emphasize their specialties. The best firms also provide guidance on the costs of the renovation as a rough guide to get you started. We have found that this upfront approach to pricing transparency reflects the firm’s commitment to honest and thorough communication throughout the project.
