Our Comprehensive Remodeling Services

When you think of a bathroom remodel, do you only think of adding some new tile to the floor and maybe a new countertop? While that’s a great start, Cortese Construction Service Corp. wants to take your project even further. Our expert team can help with the complete design phase so that we help you visualize your perfect bathroom and put it down on paper.


We work with you on everything, including the plumbing and electrical in the room, so our design will be fully functional and efficient.


Once we have a design that matches your vision, we’ll have you come visit our showroom and let you decide on the best materials and selection components for the total remodel. We have a large range of tile options, bathroom fixtures, custom cabinets and vanities and countertop, so whatever bathroom is in your head, we can make it a reality!

Once construction starts, we’ll make sure to communicate with you through each step of the process so that you know and understand exactly what’s going on and what you’re paying for. By the end of the process, we’re confident that you’ll absolutely have fallen in love with your remodeled bathroom.

  • What Our Clients Are Saying

    ”We contacted Cortese Construction because the previous contractor whom we hired from another company built us a faulty shower. It was leaking through our shower floor and into our basement. We were referred to the Cortese handyman service which turned out to be the best option since it was a small job. It was also financially reasonable for what we were asking for. The work involved removing the tiled shower floor, the bottom row of the tiled shower wall, the marble threshold, and the shower door (which we were able to reuse). They also had to fix the faulty plumbing that was in place. Jake was the guy who came and did the estimate. He was extremely professional and communicative. Cale was the guy who did all the manual work, including the demo and the rebuilding of the shower. This guy is amazing at what he does. He is extremely knowledgeable, thorough, and professional as well. We have had such a good experience with Cortese Construction that we will not look elsewhere for other home improvement jobs in the future." — Subashini P.
  • What Our Clients Are Saying

    “After many years of research and looking at bathroom remodeling I decided to convert a 1920 sunroom into a SPA bathroom. I spoke with 4 construction companies. Cortese was the most easiest to work with and met my budget needs. Nick developed a few great floor plans. Ron the carpenter did an excellent job turning the sunroom into a room of my dreams. A soaking tub by the windows and a walk in rain shower with a pebble floor. I love it! I lived with only one small bathroom upstairs with an old pedestal tub for 15 years! Brian made sure everything went according to plan. Cortese is all about customer satisfaction. They truly want you to be happy. They went above and beyond my expectations." — Kathleen K.
  • What Our Clients Are Saying

    “My wife and I hired Cortese to completely renovate a 100 year old full bathroom in our City of Buffalo home. From start to finish, each employee we dealt with was professional, courteous, and gave us hope that truly exceptional customer service, while rare, is still alive and well. Phil and Michelle walked us through the planning process and gave great advice on selecting styles and materials. Tyler and Chelsea, who were on site at our home every single day during construction, kept us informed every step of the way, and did exceptionally high quality work. The end result was a custom bathroom that is even better than we originally envisioned. Even more remarkably, the project was on time and completed on schedule! I simply can't recommend Cortese Construction Services strongly enough... We will be using them for every project and renovation moving forward!" — Sam R.
