Great service, great communication & great work
I am very happy with my new Four Seasons Liferoom. From the initial meetings to completion of the project, the process was very easy. GDM is great regarding communication, service & the work was very well done. Everyone on their team is very nice & personable. I would highly recommend them.

Lots of experience and “Can-Do” people
We needed to replace an old Pella sunroom after 35 years—tired of fighting the leaks! After some research and some luck, we found Four Seasons Sunrooms and Rob Shipstead at GDM Construction. Rob is Four Seasons contractor in the South Bay. Before starting GDM, Rob had been installing the Four Seasons windows for over 25 years. We are very happy with our new room. We were extremely happy with Rob and the guys st GDM. Very can do. Always felt that their primary target was/is customer satisfaction. Highly recommend.

GDM Construction & Design is the way to go!
I usually don't take time to sit and do a review on a company but GDM was so outstanding, I just had to. I recently interviewed 4 companies to get quotes on adding an enclosed sun room onto my home. GDM was the last of the 4 companies that came out here to talk to me and give me a quote. Instantly, after speaking to Mark (their salesman) I knew hands down that they were going to be the best and I wanted to go with them. Truly, I couldn't be more pleased with everything, from start to finish. They were so professional, polite and prompt. They knew I was moving my elderly Mom into my home and needed the space ASAP and they were here every day, until they finished my room. Things got started right away and in a 2 week period, they were done. Rob (the owner/contractor) was here daily, checking up on the job and making sure things were done perfectly and on time. The Four Seasons panels are insulated and gorgeous and the windows, slider and skylight are all energy efficient. I absolutely LOVE the addition to the house and have not one complaint, other than I will miss their friendly faces. If you are looking for a beautiful sun room addition, look no further than GDM! Seriously, you won't be sorry.

Simply Excellent
I found this place through a brief Google Maps search, and based on the owner's great phone manners, I went with GDM. What a lucky strike! After working with him through the quote and job, I found Robert to be honest, fair, reliable, and prompt. Pretty damn knowledgeable too. Add in a decent sense of humor, and he's a guy I'd work with over and over again. We put up a Four Seasons sunroom on an existing second-floor deck. The deck was sloped, but the final product was plumb and true to better than my eye could see. Every piece was carefully measured, cut, and fit, and the final product is outstanding. Windows slide effortlessly with the touch of a finger; colors are exactly as we chose. Functionality and aesthetics are simply excellent. I was watching the work progress fairly carefully, and every time I asked a question or made a suggestion, Robert and his crew were already "on it", either with me or ahead of me. Also, I had a couple of jobs going in parallel, and Robert even took over some of the (extra) stucco work, with no extra charge or nickel-diming me after the original quote. Highly recommended.

Exceptional Four Seasons sunroom
My dining room sunroom was leaking for years. I interviewed more than (6) Silicon Valley based sunroom installers and could not find a contractor that had positive user reviews. Last year was the last straw as the rain started destroying my rug, due to a leaky sunroom frame. I started my search again and found Robert S. from GDM Construction. GDM just completed the installation of my new Four Seasons sunroom. This work was my first construction project and involved an outside wall. I was very nervous after hearing horror stories from my friends about their renovation work. No need to worry! All of the other GDM reviews before me are absolutely true. Robert's team was extremely professional, on-time, considerate of my property and even provided additional enhancements to the structure at no additional cost. Another major difference between GDM and other proposed sunroom installers was the fact that Robert built a temporary wall between the inside of my house and the sunroom work. Other installers explained that they would hang a tarp, which would still leave my entire house exposed to the outside. My sunroom now looks beautiful. I wish that I had found Robert and GDM four years ago. This experience was so positive that I am trying to identify other problem areas within my house that Robert can fix.

And you may rest easy knowing that the Four Seasons materials combined with GDM’s professional installation will serve you well for many years to come. Thank you again for the opportunity and we look forward to your next project!

Terrific Job!
The team at GDM Construction did a terrific job on our second story sunroom project in San Jose! We had a large balcony (224 sq. ft.) overlooking the backyard and above the family room. Heavy rains last year resulted in leaking from the balcony to the first floor through the walls and ceiling. I hired Robert Shipstead and his team at GDM Construction to replace the surface of the balcony and install a Four Seasons Sunroom to cover the entire space. Now we have additional living space that will allow us to stretch out and relax throughout the year. The GDM team of construction professionals ensured that our job was done right and communicated the status throughout the project. The team was always on time, accommodated our schedules, left the job site clean, and made sure all of the permits and inspections were completed properly. I had a horrible experience with my previous contractor (Sunrooms America), who left town with our large deposit and is now out of business. GDM Construction has restored my faith in construction contractors and I would recommend them to anyone looking for a sunroom contractor or any home improvement project. Four Seasons has a great product and GDM (CA license #1027191) did an exceptional job installing it! Best regards, Steve R

Platinum Standard
Fantastic to work with, extremely accommodating, set the platinum standard for superb, high quality workmanship and exceptional customer service. Robert and Mark converted a never used patio into a beautiful “Life Room”. An ideal, year round living space that is fully functional in virtually any weather or climate condition. Picture an open-air veranda that within 15 seconds transforms into a partially or totally enclosed outdoor family room. Customized in our case, with their expertise, to include a 55 inch TV, stereo speakers and a place for a pet African Grey parrot. Which provides the perfect environment to watch sports and movies and entertain; or work in natural peace and quiet. Heaters, mister and flooring; a roof with skylights; even gorgeously backlit screens that raise and lower at the touch of a button to maintain comfort—create the ultimate indoor/outdoor hub for family, friends and clients. We are so impressed with this company and their product, we’re already planning the next project. Our “Life Room” is an amazing value and an extraordinary way to enhance living and lifestyle every day. Robert and Mark handled every detail and their competence and professionalism truly made this endeavor a fun and rewarding adventure.

Extremely Happy
We are extremely happy with our new 300 sq ft Sunroom. We really needed a proper dining room to invite family and friends. We’ve been planning for this Sunroom for years, did a lot of research, and interviewed many Contractors until we finally settled on Four Seasons GDM Construction. They did an awesome job exceeding all of our expectations. I had asked Robert from the very beginning I needed regular communications. As an engineer, I had much higher expectation. I wanted to be involved in every step of the way. Robert and his crew exceeded those high expectations. I loved how meticulous and professional they were paying attention to the minutest detail. Robert and his crew were always on time, respectful and sensitive to everyone around them including sleeping family members, neighbors and even our cat. We felt very comfortable leaving our house wide open during construction. Robert likes to take a few projects and do them well. That allows him to deliver on time the highest quality. We never had to worry about other projects competing with ours in any way. They were there until the job was completed to the very end. Our Sunroom has become the envy of our friends an neighbors to whom we recommend Robert and his crew.

Great quality work, fast and efficient, very easy to work with
GDM installed a new Four Seasons Sunroom replacing an existing 25 year old sunroom on the back of our house. They were able to reuse the existing cement pad. The new sun room is well designed and well installed. The double pane glass keeps the room insulated from both the cold and heat. Robert and his crew were very easy to work with. They answered all of our questions and took the time to fully understand our vision of the final room. The crew was amazing. They were fast and efficient. Each member of the construction crew was an expert at his job. The installation was very fast and the results are exactly what we had envisioned. They exceeded our expectations by offering suggestions for small enhancements that we had not thought about such as connecting the new room to the house HVAC supply. Their detail work was also very meticulous. They did a thorough cleaning of the new room as their final task. It was ready for use when they left.
