Amazing Experience!!

I had my two homes installed.  The response was very quickly to set up a presentation. The sales rep came out with samples and choices.   The crew was fast, courtesy and efficient. I highly recommend this company.

Amazing Experience!!

I had my previous home installed. They did an amazing job i asked them to come to do my 2nd home.  The response was very quickly to set up a presentation. The sales reps came out with samples and choices. I was kept updated on timelines. The contractors were really friendly and professional.

Beautiful custom made sliding door

My experience with Design Windows and Doors was a positive experience. I was pleased with the time that my special order took to arrive and be installed. The team that installed my new sliding door was knowledgeable, polite, arrived on time and was very clean. Considering that installation was upstairs directly leading out to a balcony. Great job fellas !!

Love our new Front Door!

First let me say we love our new Front Door! everything went pretty smooth and I was in constant communication with the project manager Arthur. The installers were professional and did great work. I would recommend them to my family and friends.

GREAT SERVICE

Our experience with this company was a good one. I don't remember the guys name who first came to our house to give us a quote. I want to say Mike? He was very upfront and honest with us and took the time to answer our questions. Afterwards once all the papers were signed we got our installation date. Michelle was our project manager and she was great. Very polite and easy to work with. Our installers were also great. They were there on time and done in less than half a day. They made sure before they left that they went over every window with us to make sure they were working properly. Overall it was a good experience. The only tough part was the long delay between the sale and the installation. But I understand that materials are tough to get now. Michelle was very helpful at explaining the delay and keeping us up to date.

Window Install was GREAT! (8 month project)

My experience was AMAZING, the project took place between Jan. 2021 to Aug. 2021! When we received our quote from Mike McLean, he was very honest and clear with his explanation of the different window options we had and the pricing of the project. He showed examples of past projects, that ranged from retrofits to fixing botched jobs from competitors. After we had chosen our windows and options. we were assigned our project manager, Martha. Goodness gracious, I did not think I'd come across someone as dedicated and hard working as Martha. all through out the project she was constantly on top of everything. She handled all the documents pertaining to HOA and other documentation, save for the documents that required us to fill out. when it came to the windows and the project she would always keep us posted on how things were going no matter if it was letting us know about approval ETAs or just letting us know about information pertaining to the factory and our order. Come June we receive our windows are ready for install and Luis who installed them did a splendid job. He removed the old windows and installed the new ones in less than five hours, all while flying solo! But alas! we were missing screens and the lock on one of the panels wasn't behaving too well. I let her know and before I could say warranty she had already called Milgard about the screens that were missing and had set up for a technician to come out and check our lock. The screens were back ordered and the lock issue was resolved quite quickly and the lock was behaving as intended. after the initial install we had to wait two months until the time of writing this to receive the screens and all through out Martha was keeping us up to date on what was going on with our order. On 8/24 our screens were delivered and installed by Ray! the install was quick, he also took care of some touch up on the paint for the frames. He also told me a little more about our windows. I want to thank you all at Design for making this project a great adventure. Special thanks to Martha for her dedication and diligence, Mike McLean for helping us with choosing our windows and starting our project, and the Techs who installed our windows, Luis and Ray, even though I was watching and asking questions they were working efficiently and never lost focus. THANK YOU !!!!

Wonderful

I want take the time to appreciate all your hard work as a team. It started out with the boss Joe who gave me a reasonable estimate.Then came Michelle my project manager which she communicated the whole time with great customer service. Finally the 4 workers that came to my home showed up on scheduled days were always right on time which is a big deal for me l, they came in and got down to business, they were very professional and finished installing 5 sliding doors 8 windows in 2 days both days leaving everything absolutely clean they also took the old sliding doors and windows. I had an amazing experience thank you to all of you that were part of my project. Will definitely refer them.

Great

The whole process was great. From Bill the salesman who advised and showed me what I was buying. and Michelle my coordinator was really great to work with.Very happy, friendly and upbeat, she updated me weekly on the status of my windows. Also the installation was done on the date promised. Michelle was wonderful.She even contacted me after the installation to make sure I was happy with everything. The most important part was the Installation crew. I haven't seen a crew more organized and efficient, thorough, and clean than this group of men. In the end I have nine beautiful new windows in my mobile home.The finished look is perfection. I couldn't be more happy. My home is much cooler. No more hot glass. Thanks to all involved in my upgrade.
