This company replaced some windows with three La Cantina Multislide doors. The crew is professional and exceptionally skilled, they are on time, communicate very well, completely trustworthy, superb job, reasonably priced. After dealing with contractors for the last year in my home, this was a refreshing change! I am beyond pleased and highly recommend this company and their crew. Professionals with a vision, skills and expertise. read more

Sean and Brian went above and beyond to complete our project to our satisfaction (design/engineering, permits, construction, and close-out). The installation is high quality and it has made such a dramatic improvement to our home. We are really enjoying the finished product. read more

Sean And Will were the best! They were always on time, hand shake kind of guys...their word is worth gold. I've worked with a lot of contractors and these guys were the best, and my fold back doors are beautiful! Would use them again in a heart beat! read more

See all

Sean and his team just finished the installation of my 3rd La Cantina door and it turned out fantastic. I had him install a 3 panel and 4 panel 2 years prior. The craftsmanship is 2nd to none and you cannot ask for better service from Sean and his team. Prior to installing the doors, I had multiple contractors come out and provide bids. You will not find another person that is more knowledgeable or honest than Sean. Rather than providing a quote for a more expensive option, Sean will guide you towards what is the best option based on the condition and layout of your house. read more

Cornerstone and Brian were awesome to work with. They followed up on an installation of a folding door done in our family room to our back yard which was completed about 4 years ago. When our German shepherd puppies decided to snack on the rubber seal in the track, the doors and screen wasn't tracking right. Brian quickly agreed to fix the issue and didn't charge us for the service even though it was clearly caused but us. This kind of service is hard to come by these days. The initial installation went great as well. I wouldn't hesitate to use Cornerstone again or recommended highly. read more

We had a couple of bi-fold doors installed by Cornerstone to replace old and failing sliders. It is an expensive upgrade project but the Cornerstone team took some of the sting of expense away as their team was very professional and one of the best contractors that we've worked with over the last 30 years. The team responded timely for an estimate, acted quickly to begin the project then worked swift and were very clean to demo and then install once the doors were ready from LaCantina (took about a week for demo and install). I'd highly recommend Cornerstone read more

We had a 10ft. x 12ft. tri-fold opening installed by Cornerstone well over a year ago. Recently had a minor issue with the outside stucco above the opening (NOT the stacking/sliding doors) and Cornerstone was on it immediately and resolved 100%. Sean, Sam and crew are the most professional team you could ask for and their customer service is the absolute BEST!! If you are looking for a quality product, professionalism AND great customer service, don't look any further....Call Cornerstone! read more

We are so grateful for Sean and Cornerstone Openings. From start to finish to maintenance, Sean and his team are the best. We decided to add a La Cantina door to open up our living area and interviewed several contractors. In the end, Cornerstone had a very competitive price and had exceptional understanding of our objective. Sean always did what he said he'd do and followed-up swiftly. His crew was clean, respectful of our home, courteous, and very thorough. I suppose after doing hundreds of these installs, you get pretty good. Couldn't be happier with Sean, his team, or the project. Well done Sean! We are grateful for you. read more

Look no further... I cant recommend this company enough! I am an Interior Designer/Project Manager and have used Cornerstone for a past client. This is a big purchase, so trust me when I tell you that Sean and his team are the absolute best in their field! Their customer service is above and beyond and their skill set and attention to detail is impeccable. I recently asked them to service a product that wasn't purchased through them and without hesitation, they were out to assess the situation and oversee the necessary adjustments without charging a dime!!! Sam, you are one-in-a-million, thank you for taking care of me! Thank you Sean, for running such a quality business, truly a rarity these days... my review is obviously just one of 30+, five star reviews!!! read more

This is a top quality customer devoted company with high values. They followed up with us way beyond contractual requirements. The work and product quality is the highest. Expect a positive and pleasant experience when you deal with them. You will not find a better team for your needs. read more

Cornerstone Openings - My doors - Door Sales/Installation Near Me - Dana Point, California

Cornerstone Openings was referred to me by LaCantina doors and my husband and I are genuinely glad with the entire job from ordering to installation. They kept us informed and were easy to deal with throughout the process. These people are serious professionals, reliable, honest and a delight to work with. I strongly recommend them without reservation. Thanks to Sam, Sean and Will for your work on our behalf. read more

Great company. Sam is a phenomenal guy. Bought a door a year ago and was having trouble and he drove from Dana Point to my house in Huntington Beach the same day to take care of the problem. I'd wager 99% of other companies would have said well gee I'd like to help you but I just can't. Maybe you should call the guy who installed the door. Sam truly understands what it takes to deliver the best customer service possible. Honestly I never thought I'd encounter that from a company that sells doors. I am so happy to know I can depend on Cornerstone. I wouldn't think about ordering a product they sell from anyone else. read more

We cannot recommend Cornerstone Openings highly enough. They have the best prices around but far beyond that is their customer service. Will was very helpful and came out to meet with us and make a recommendation since we were torn between bi-fold and a slider. Will gave us great advice and didn't try to up-sell at all. Where they really came through was on the installation. Our installer thought the framing was off and that it wouldn't fit, and our general contractor basically washed his hands of it, so we were beyond worried that this huge investment was not going to work. Sean, the owner, responded to us right away, came out the next day to take a look, and promised that he would personally take care of it. The next day, the door was installed, and looks beautiful. This was a huge relief of course because of the money involved, but it also was so refreshing to have Sean take ownership and make sure it got taken care of, when it wasn't even a Cornerstone problem. We are beyond happy that we went with Sean, Will, and everyone on their team. read more

Sean did a great job getting our La Cantina sliding doors purchased and installed. We love our doors and honestly would have installed them sooner if we have met a quality contractor, like Sean, earlier. Sean's team is amazing and they showed up and got the job done which is rare for contractors. One thing that makes them excellent is they only work on installing doors so the crew knows exactly what needs to get done. It was orchestrated perfectly and we are having a party Saturday night which some what risky with all the work needed to shore up the home, pour footings, new header and get the doors installed, yet they cranked and even ended 2 days ahead of schedule. We love how the doors let so much light in and connect us to our backyard. Highly recommend Sean and La Cantina doors! BOB read more

Will, Sean and the staff were amazing, they were ahead of schedule by several days. I was looking for one company to complete the whole process and Cornerstone Openings had this and it was perfect. Will answered all of my questions and concerns I had, I contacted him several times and he always got back to me very quickly. This process was a breeze from start to finish. Will even came out and clean my La Cantina doors. Installing these doors opened up my family room and they really showcase my view. I wish I could do more doors. This was the best experience I had working with a contractor. Thank you for the amazing doors!!!!! read more

Will was very helpful with deciding which doors would fit our space the best. His employees were punctual, courteous and did a great job. Beautiful product!! read more

My wife and I have very good friends that did a major remodel of their home and they installed La Cantina Bi-fold doors and it was very impressive. Thereafter we decided to do a major remodel of our home in the Mystic Hills area of Laguna Beach which included vaulting our ceilings and adding bi-fold doors and windows to replace our old aluminum sliders and picture windows. I was told to visit Cornerstone Openings' showroom in Dana Point and I met Sean and his staff. The showroom at Cornerstone is very impressive and not only offers what kind of doors you think you want but also displays other very creative bi-fold idea examples for picture windows too. After my visit to Cornerstones' showroom I went back to my architect and told him to make changes to my plans based on what I saw at Cornerstone and ideas that Sean (owner) suggested. Well I got my final plans from the architect and presented them to General Contractors that were bidding on the project. I finally decided on a Contractor and he said he had worked with Cornerstone Openings. Ultimately I signed the contract with the General Contractor but what I eventually found out was that he ordered the La Cantina bi-fold doors through another company called The Pelletier Company. The remodel project went well and the La Cantina bi-fold openings and new custom previous picture windows were replaced with new very cool bi-fold features. Stay with me because this is where I found out dealing with the right people makes a huge difference. About a year after the large bi-fold opening was installed it started to shows signs of not closing in sequence with the other doors. At first it was the windows becoming tight to close but ultimately would just hit metal on metal with side doors. I called my General Contractor but the number was not active. Then I called The Pelletier Company that ordered and provided the La Cantina bi-fold doors and windows. I actually connected with the Pelletier salesman that handled the ordering and purchase of the windows and doors and said "no problem" I'll make a few calls and get you taken care of. Well after a couple weeks of silence I then sent an email to Pelletier Company reminding them of their promise to take care of the issue. The Pelletier Company then went dark on me and did not respond to calls or emails after promising to "take care" of my issues. Feeling lost and my wife on my back to get it fixed I called Sean at Cornerstone Openings who originally gave me great advice and ideas on the windows and doors but didn't get the order because of my contractor. I told him my nightmare story of dealing with these other companies and their non-response and my personal regret not using him after giving all the great ideas but not using him because of my General Contractor. Sean was super supportive and said he hears the same story all the time. Bottom line he sent out his right hand man, Sam and they fixed my issues within 20 minutes or less with a few adjustments. The doors now close like butter and Sean did not charge me one cent. His guy Sam is a real pro and even looked at other doors that did not have any issues that I could detect but he made a few preventative adjustments. As I mentioned I live in Laguna Beach and the terra firma is always moving and will require occasional adjustments to your doors and windows. I learned that Cornerstone Openings is all about service and Sean and his team stepped up even though they didn't get the original sale. Simply stated, if you are looking for bi-fold doors or windows, Cornerstone Openings not only has the best display showroom they are a solid company with very impressive business practices.

Perfection... had a folding door put in. Could not be happier with Cornerstone. They did a great job and delivered on all promises. Rare company and a must if you want a folding door. read more

When we decided to add bi-fold doors to our home I contacted the five top manufactures. Most of them would sell me the doors but I would have to contract locally to have them installed. After pushing them I did get some potential names of contractors, but it would still have been two different transactions. The only one that had a local installer was La Cantina. I got estimates from them all. After meeting them all I was leaning toward Sean Scholl, owner of Cornerstone Openings and the local representative for La Cantina. I asked for a couple of references. It turned out that one of the names he gave us were personal friends. We went over to their house, saw the install, and asked about Sean. They said he was terrific and they loved the job he did. I signed the contract with Sean. This was the best construction experience I've ever had. He promised excellence and he delivered! He showed up every time he said he would, (even when he didn't feel well), returned every call immediately, and had the best people on the job, (that also showed on time). He noticed that we were very particular about how we kept our house and went above and beyond to protect everything, even buying brand new drop cloths and enclosing the work area with heavy plastic and a zipper opening. The finished job was fantastic! We highly recommend Sean and his crew for any job they choose to take on. This is a guy that won't provide anything but the highest possible standard of not just the finished product, but the entire construction experience. read more
