General Contractor reviews in Glendale, Wisconsin

Loved it

Great work and fair price!

Great local contractor. Solid reputation.

Maretes has great attention to detail, and is a great resource!

Really listened to what we envisioned and brought it to life. Communicated very well every step of the way.

Maretes has done work for me several times and has grown her business because of her great personal service and focus on customer satisfaction.

A great company to work with. The owner of COR Improvements is easy to talk to and a lot of fun to work with.

Recently I met with the owner and was totally impressed by insight, experience and a willingness to assist us. Just having a conversation with Maretas will help you with knowing this is a contractor you can trust and has your best interests at hand.

I continually am impressed with this organization and owner. You will be treated with respect and provided excellent communication along the way. They do great work and have a sincere interest in what they do. If you want to work with great quality people, be sure to meet with COR before making any decisions.

I called because I needed a door repaired. I spoke with Justin who told me they didn't repair doors, but he would try to find someone who did. He was kind enough to take time out of his day to look up several companies that he thought could help me with my problem. I felt the need to give this company a five star review even thought I didn't need or use their service at this time because, with employees like Justin should the need arise in the future where I do need the services they offer, I will definitely call COR first.

We’ve had the good fortune to work with Maretes and COR Improvements on several projects and are always impressed with their quality, professionalism and especially the great outcomes of their projects. Highly recommended!

We contracted with COR to put a sun room addition on our house. It was roughly 14' x 21' plus a full basement below. The sub-contractors were all coordinated and kept to their schedules. The quality of the sub-contractors was excellent. The only variance from the original estimate was where we needed a couple of changes due to some underground electrical and water lines not found via Diggers Hotline and some HVAC changes we opted to make due to equipment age. The final result was on time and on budget and turned out great. I highly recommend the company and Maretes, the owner really has raving fans.

COR did not provide the quality and value that we expected for our recent, March 2020 to August 2020, bathroom remodel.

Design, coordination, communication, workmanship and efficiency were not up to reasonably expected standards. Our house was not even properly secured when work was done in our absence.

The little 5 by 9 bathroom project that we were told would take about 4 to 6 weeks ended up taking 18 weeks. The project also consumed an unreasonable amount of our time and energy to monitor results and point out errors i.e. tile laid improperly, half-wall not square, etc.

We would not use COR Improvements again and would not recommend COR Improvements to others.

I heard nothing but wonderful things about Maretes and her company. I was really impressed with her communication and the work she produced that I decided to hire her to build my salon suites at Good Hair Day MKE. I started working with her back in mid December 2014-March 2015. It was a MAJOR renovation job, 2000 sq ft, 9 suites, manicure/pedicure area, bathroom, and waiting area, all built from scratch. Custom build cabinetry/countertop with shampoo bowls installed in each suite, new flooring, electrical, plumbing, HVAC system, fire sprinklers, painting, putting together equipments, etc. It was the most stressful time I went through from purchasing my salon to completing construction in 2.5 months in order to open on time. There were a fair share of unforseen stuff that occured which was out of our control. But Maretes was always quick to work around the unforseen stuff, made my life so much easier because she was on top of every aspect, regularly stopped by to make sure everything was running smoothly and made sure everything was up to code for inspection to pass. She also communicated with me on a daily basis, calmed down my nerves and went above and beyond. She even went as far as making sure the inspector would show up to the salon as scheduled and when that fell apart on the day of (the scheduled inspector called in sick at last minute), she kept calling the supervisor and demanded that they send another inspector which he finally gave in and showed up himself. If she did not go above and beyond to make this work, I would not have been able to open my salon as scheduled! And the best part was I had no idea of the hot mess that transpired that morning until after giving me the good news that I could officially open my salon. That alone shows us what a great, hardworking person she is, that she will take on any issues that arise just to alleviate your stress! I honestly do not know what I would do without her and her team. Another part that stood out about her is the fact that she throughly listened to all of my visions and was not quick to shut down any ideas I had. If there were any part I was unsure about or changed my mind, she was quick to work around that.

I hired her again around end of April 2020 while my salon was shutdown due to Covid. I had to install new floorings due to water damage coming in from outside building (which the condo association is working on). Maretes, her project manager, and her team was able to complete the flooring and repaint within two weeks and right in time to reopen. It was a wonderful experience working with her and her team again. And BONUS, they have a really cool set up where you can check through an app daily and see the progress they made, posted daily updates, information and pictures. I communicated with her project manager daily which was still great and very effective.

I will always stick with Maretes and her team for anything I need, especially future projects. I am hoping to expand and she will always be the person to go to! She works really hard to be one of the best company, to go above and beyond, have excellent communication skills, makes sure she hires top notch reputable contractors, have trustworthy team staff, and will work with ANY issues you may have. She will always make sure you are left completely happy with the results!!

COR Improvements did our kitchen remodel - new floor, granite counter top, and back splash in both units of our duplex. Quality workmanship, professional staff, and all work completed in a timely manner. We highly recommend COR Improvements for your home remodeling projects.

We did two back-to-back projects with Cor improvements. One was a complete bathroom remodel (with age in place features) and the other involved taking down a supporting wall between two rooms (and making it one room.) Their communication with us was extraordinary during the project and they were very responsive when problems arose. They dealt well with the surprises that arise with remodeling in older houses. The quality of the work is excellent and they dealt well with the village inspectors.

COR Improvements is a great company to work with. They paid attention to detail, were very clean and finished ahead of schedule. Their entire team was professional. We couldn’t have asked for a better experience!

COR IMPROVEMENTS is an awesome team to work with and go the extra mile to make your project run smooth and the end result turning out exactly the way you want it! Thank you all for a Beautiful job!

COR Improvements has been amazing to work with. Their attention to detail is remarkable, and the transformation that took place with our kitchen and bath was amazing. We received at least weekly communication with updates as things progressed. Every person who came in to do work was professional and so easy to work with. This was the second project we have used them for and as far as I am concerned, the only company we would use for our improvement projects.

COR Improvements was great to work with from beginning to end on our kitchen remodel. They listened to what we wanted and worked with us to create a design at a manageable budget for us. The project included a complete kitchen remodel and new flooring and trim throughout main living space. They were professional, responsive, on time and within budget…not sure what else you could ask for.

We hired COR to do a complete remodel of our kitchen/dinning room/bathroom on first floor. The project was a big undertaking requiring walls to come down and relocating a bathroom. Everyone at COR from the staff to the contractors were professional and great to work with. They were great at communicating updates as the project progressed and following up with us on things they needed from us. We have heard horror stories of others who have done remodeling projects and are happy to say that COR was the complete opposite and a joy to work with.

Maretes was just the best to work with - so professional and fun to work with on this project. They really took our vision and made it into a reality. We would highly recommend them to anyone who wants to do a remodeling project and would use them again in the future!
