I would strongly recommend Corniel construction for their services.
I hired them for some painting and flooring work and the job was done perfectly. The quality and timeliness was much appreciated.
In addition, they also took some time to help me fix some small issues with my bathroom which was even outside the scope of the project.
I would love to hire them again and recommend them to my friends.

We hired Corniel Construction to renovate our midtown Manhattan apartment. We added 700 square feet of ceramic tile and renovated the fixtures in the bathroom. The project was completed quickly, and we are very pleased with the results. Waldy was extremely professional and responded quickly to all our concerns and took initiative in making the project look right. I highly recommend this company and look forward to working with them again for our next renovation project.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
Renovation pricing depends on the scope, existing conditions, finishes and building requirements. We review these details during consultation and define the scope before preparing a proposal. Schedule Your Consultation to discuss your Manhattan renovation.
What is your typical process for working with a new customer?
We start with a consultation to understand your property, priorities and intended scope. We review existing conditions, finishes and building requirements, then define the work and proposal. During construction, we coordinate access, deliveries and the work sequence, and keep you informed as the project progresses.
What education and/or training do you have that relates to your work?
We pursue ongoing learning through construction courses, seminars and contractor business resources, including the SBA, SCORE and SBDC. We discuss the qualifications and documentation relevant to your project rather than treating a general profile statement as proof of a specific certification.
