Seaport provides excellent service and great products. I had my front entry door replaced 12 years ago by Seaport. The door still looks great today. Recently I had Seaport replace my kitchen door with a modern glass door. The door looks fabulous and brings my kitchen alive. Thanks Seaport!

Wonderful company. I highly recommend them and they were the only company who could do my VERY custom windows without destroying my kitchen counter tops. Beautiful work and all the workmen great to work with. Customer service always there from start to finish.

Seaport did a great job helping choose and then install kitchen windows and doors. Alex is very knowledgeable and takes the time to get things right. What impressed me most was the attention to detail by the crew. Especially the interior and exterior molding, paint match, and general installation. I will definitely contact Seaport for all future work. I highly Recommend Seaport. Tom C, Cypress CA

Communication on point 👌🏽We had a lot of different contractors during our remodel, but none stood out as much as seaport. They communicated each morning their plan of action and followed through, it was a real pleasure working with Alex and his team. Highly recommended.

Really enjoyed working with this company. The owner Alex came over on numerous occasions to make sure the project was going as planned. And the installation team and Alfonso were friendly and knowledgeable. They did a great job on our 2 large sliders.

Seaport was great to work with.Alex and his team, from office to the onsite workers, were attentive and prompt. Don’t hesitate to call them first.

Got new windows and a patio door installed. Both were installed efficiently and professionally. Always great communication. I just had a bunch of remodeling done from different companies, and Seaport was by far the best and easiest to work with and coordinate. Very fair pricing. I’ll definitely be recommending them to all my people interested in window work.

When it comes to master craftsmanship, my recommendation goes to Seaport Windows and Doors. Mr. Alex Herrera, the owner, is a true artisan whose dedication to quality shines through in every project. From start to finish, his team delivered nothing short of excellence. Their expertise and professionalism are truly commendable. I particularly appreciated the seamless interaction with Mr. Herrera's staff, each of whom shares a longstanding relationship with him. This speaks volumes about the company's culture and commitment to fostering lasting client relationships. Furthermore, Ms. Jennifer N ensured that every aspect of my project was meticulously covered to my utmost satisfaction.Rest assured that whatever project you have pending; you're in good hands with Seaport windows and doors.

Seaport did an amazing job at our home. While it was a major project that involved removing and installing 35 windows, they did it so unbelievably surgically and meticulously that it was a minimal interruption to our daily lives. The installers are professional and respectful, and their daily cleanup was impeccable. They regularly worked overtime to complete daily goals, and they left everything exactly how they found it each day. Alex is extremely knowledgeable and helped come up with creative and innovative ideas for issues we were looking to resolve. He ultimately came up with a product and plan that was perfectly suited to our needs and wants. The windows turned out beautifully, and the overall transformation to our home was incredible.We are so happy with both the product and the service we received, and we could not more highly recommend Seaport to prospective customers considering using them.

Nice place!!!!!!

I went with Seaport because Alex was exceptionally thorough and thoughtful when designing our custom balcony doors. He and his team were incredibly professional, courteous, and did amazing work. I look forward to working with them again in the future

They do perfect work and the painter is a magician. If you get any windows or doors this is the place to go it's a no brainer

The window renovation worked out well. The only downside is that it took a little longer than expected, but in the end, the window looks great.

Seaport is phenomenal. They installed bi-folding doors in our house. They are beautiful and have completely enhanced the look and flow of our home.This was a big project that required significant construction. Usually significant construction interferes with your daily life, but not in this case. Seaport installed a dust wall which literally sealed off the construction. This allowed us to run our busy home without any interference from the construction.The Seaport staff is also spectacular. We knew what they would be doing day by day. Each day we would receive a call from the Seaport staff letting us know when they would be there and what they would be doing that day. Things like this really set Seaport apart from others.Finally, Seaport’s work product was top notch. I am still amazed that they cut a giant hole in our house and I can’t see any patch work. The stucco and internal drywall and texture coat are perfect and the doors themselves are of the highest quality.I can’t recommend Seaport enough. If you are in the market for doors or windows, give Seaport a call.

Our doors were a special order that required a great deal of coordination. Crystal was phenomenal about dealing with the details. Peter did an outstanding job on installing them and making sure every detail was tended to with an expert 's eye. Alex was always available to answer questions and make sure that the project went smoothly.

18:17 26 Feb 18

My new windows and door are beautiful Seaport did a very professional job and I could not be happier with the results. I highly recommend them to anyone who is planning on replacing their old doors and windows. They are the best!

06:58 22 Nov 17

Seaport staff and install team was top notch. From the start with a very thorough review of my needs for new replacement windows, a timely and professional plan and bid was presented. Alex Herrera kept me informed and answered all my questi9ns in a timely manner. The installment team was courteous and professional. They did everything they said they would and more. I’m so happy with the job they did. I highly recommend Seaport Windows and Doors.

These guys are first rate, meticulous care and attention to detail.

Our home was 'personally-built' by the original owner in the early 1940s, and nothing is plumb or level, so it's not easy for contractors to work on. When my husband and I had to replace our 3 large picture windows (4'x7'), our friends highly recommended Seaport Windows and Doors. This has been the best contractor experience we've ever had--everyone at Seaport has given us superior customer service! Alex, the highly knowledgeable owner, assessed our job, educated us on the available products, gave us options, and then gave us a very good price in a written quote that clearly detailed an appropriate payment schedule. Alex also quickly responded to our emails when we had questions. The office staff kept us well-informed of where we were in the process of having custom windows made. And the installation crew, Jose and Leslie, were amazing! They called us each day to let us know what time they would arrive, and they were always on time or early. They were highly professional, hardworking, polite and pleasant. They kept me informed throughout the three day installation process, maintained an organized work environment, cleaned up at the end of each day, and respectfully answered all of my many questions (unlike many contractors who treat women as if they are brainless). I watched the entire process and it was a pleasure listening to Jose and Leslie logically solve the installation issues they encountered in our 'twisted home.' And never once did I get the impression that they thought it was a "difficult job" even though I know just how difficult it is to work on our house. The windows look incredible! When we do the next part of our remodel, we plan on hiring Seaport to install our doors, casings, and trim. We highly recommend Seaport Windows and Doors!!

I had an excellent experience with Seaport Windows. Alex Herrera Is a very knowledgeable. He was able to explain the problem that had developed with the windows we installed when we built our home. His proposal was reasonable. We gave him the OK to order replacement windows. Installation was flawless. I highly recommend Seaport Windows and Doors.

18:34 28 Feb 17

Seaport, Alex and crew, did a great job on my window project. Very courteous and professional.

Having worked for Seaport Windows and Doors two different times and I currently am working in the front office. I have seen this company's growth and longevity over the years and it amazes me! People always think the grass is greener and with the social media so big, they try to lash out. I can tell you first hand. Alex is a good, hard working man that has a heart of gold! He has taught me so much and the most important thing Is good customer service. I apply it in my life everyday and it truly is a life changer. Treat people as you want to be treated! I am in the center of the company and the reputation in this business and with his customers is positive, friendly yet still professional. He is a man of his word and will always take the time to help others. There are many neighborhood residents who come into Seaport's office with desperation because the company they have worked with can't be found or is out of business yet Seaport is in the same location and same Owner for 25+ years. That, more then anything, says so much! Thank you for taking the time to read this, truly honest review and have a successful day! Teri Miller

I have been working for this company for over 4 years and enjoy working for Alex. I started out working part time helping him rebuild his computers lost customers files back into the files . When working for Alex and learning his business, how he wanted it ran due to the details that went into each job. I learned so much as to how important to follow each job correctly. He has thought me a lot over the years, that now has put me into the full time book keeping position. We strive very hard to make all our customers satisfied. Sometimes with orders and the vendors not being able to make orders meet Deadlines or come damaged due to shipping, causes process of installation put back unfortunately. Some ppl not being in the full cycle of business procedures don't understand all steps on what it takes. We also service all our customers with meeting all warranties from products sold by us and others. I would highly recommend this family owned business that likes detailed custom work done by a professional!
