Seaport Windows and Doors provided excellent service. The office staff was understanding and accommodating, fitting me into their schedule to repair windows that had been installed by someone else. The work crew arrived on time, clearly explained the issues, and addressed everything professionally. I highly recommend them for your window and door needs.

Got a reconstructing sliding door from Seaport for my balcony referred by a decking company who redoes the whole deck for my townhome due to leaking issues. I have to say, I have never ever had a contractor like Seaport that makes me so surprised with the quality of their work. From start to finish, Alex and his team were so professional, thorough and exceptional. They put special coverings on my floor from downstairs to the hallway upstairs from day 1 and cleaned "so well" at each step. They even went beyond in that when the decking company did not do the flashing correctly on the sill pan and nail fin of the door, Alex sent his team member, Kerwuin, out immediately to provide instructions to the decking guys and came back again to inspect. Also to mention the painting and caulking works from Eric were so good too that I cannot even find any imperfect areas inch by inch. And the price is fair. I cannot be any happier with the door and the whole process. I highly recommend Seaport if anyone needs door or window replacement.

Seaport had competitive pricing and when we experienced a fog issue with one window they came and fixed it with no issues. Would definitely use them again.

We had a custom garden window that needed to be replaced due to leaking. Seaport was much more affordable than what other people were quoting me. They did an amazing job, the window is great quality, they were fast, and made sure to clean up after. Would use again!

Had a great experience with Seaport! I've had terrible issues with water damage in my townhome due to defects several of the door thresholds and windows. I spent two years trying to diagnose the problem and spent a lot of money on repairs unnecessarily. Alex and crew were quick to identify the issues and I can now live peacefully knowing that my townhome will survive the next rainy season.

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.

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.

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.

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.

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!!

His proposal was reasonable. We gave him the OK to order replacement windows. Installation was flawless. I highly recommend Seaport Windows and Doors.
