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!

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.

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.

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.

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!!

3 years ago, Alex from Seaport did a lot of remodeling in my Leisure World home, which I was pleased with. He put in all new windows, reconfiguring and building a pony wall in my living room and replacing a bedroom window and slider. He replaced my front door with a beautiful fiberglass door and a security screen door that people stop and look at! Replaced my closet doors into custom triple doors for easy access, shaker style. He built a 3 foot wall around my patio, removing the old blocks and replacing with stucco. Recently he made custom shaker style doors for my bedroom and bathroom, replacing old ugly doors! They match my closet doors and add more beauty to my home.

Seaport Windows & Doors Review

Linda N.

Alex came by to estimate our job and made some good recommendations and bid the miscellaneous work we requested. A mixture of window and doors, including a dutch door for the front door. I wanted them to come in with a crew and knock the work out, but they knew better, and pieced it together with the right mix of workers. Demo, Wood workers, Stucco men, Painter, Finish carpenters. It took a little longer than expected, but the end product was well worth it. Finished product is excellent. We really appreciate the level of excellence the workers produced especially Erick the painter.

We love our new windows by Seaport Sash and Door. Changing out our old windows is probably the best thing we’ve done to improve our home in 20 years. The first thing we noticed is how quiet our new windows make our house. The double pane windows improved the temperature dramatically. We love the nice tint on the outside that gives us privacy during the day yet still gives us a clear view looking outside. I’d like to mention how great Seaport is to work with. This is a well run business. They are upfront and professional. The whole process only took 2 1/2 days from start to finish. The finish work makes Seaport Sash and door stand out above the competition.

I’ve been very pleased with my bi fold doors.  The installation happened in a timely manner and the quality has been excellent.  Nine years later they look great and function great.  I highly recommend them.

Joe R.

We’ve had Seaport install windows in two locations in our house.  The first were basic bathroom windows and the second were custom designed front windows which made a major difference to the look of the house.  Alex was instrumental in getting our ideas to work, and helped avoid some design pitfalls we were moving towards.  His experience with design, aesthetics and feasability is a great resource.  The installation crews were professional and respectful.  We will use Seaport again for a custom front door.

Marty B.

They did very nice work.  It is so nice to have high quality doors installed as the previous ones from the previous owner were poorly installed and some leaked.  We had 1 window, 2 regular doors, a French door, and a large slider door installed.  They stand behind their work. We had a couple of minor issues, including one that cropped up 13 months after installation and they were corrected without hesitation.  I would definitely use them again and recommend them to others.

Lisa K.

Seaport windows and doors,  Alex is awesome and excellent Job was done. I would strongly recommend to everyone.

“My side door to my garage was in really bad shape and needed repair. We not only needed a door but all the jams and a new threshold. After receiving a flyer in the mail from Seaport, I decided to get an estimate to see the cost. Alex came out and and gave me assurances that the job would be complete with no work to be done afterword. We decided to go forward with the job and I can’t tell you how pleased we are with the results and the care that was taken to do the best job possible. I highly recommend using Seaport.”

“The Seaport team was fantastic from start to finish. Truly a seamless installation process and they kept you updated every step of the way. We’ve had them do a couple sliding doors and a few windows, and we’ll look forward to having their team complete future work. Thank you, Seaport!.”

Megan B.

“When I bought my unit in 2005, there were louver windows from the 1960’s in the front. Those definitely needed to go! Alex from Seaport replaced all the windows and 2 doors. Fast forward to 2024. Termite damage to the window sills caused water to leak inside. I called Alex to do the work. The front windows and door needed to be removed and termite damage repaired. His workers were well trained and very nice. A shout out to Tommy the door guy, Ricardo removed the windows and door and repaired the termite damage, Manuel the drywall guy, Ernesto the security door installer, Kerwin the outside trim guy and Erick the painter. Jennifer kept me up to date and came out to check on the work progress. It took awhile to get the work done bc of all of the rain this year but I am satisfied with the end product. It was worth the wait. Thank you Alex and crew.”

Elaine T.

“Seaport Windows & Doors has just completed over $30,000 of repairs on my Seal Beach home to fix leaks on 3 sides of my house.  From day one, Alex Herrera was the most professional contractor with whom I have ever worked.  Competent, straight forward and honest he assessed a multitude of issues with my home many of which I never noticed.  His first document was a list of all the known repairs with line-item costs.  Each time there was an adjustment a new invoice appeared and every time I wrote a check, I received a confirmation ‘paid in full’ document. The men who worked for him were skilled, professional and respectful.  The sub-contractors were also skilled & hard-working.  What would have taken months with another company, took 3 weeks.  The work from deck to stucco to interior wall repair is excellent.  I highly recommend Seaport Windows & Doors.”

“Everything from start to finish was 100% to all my exceptions. From Alex, to the installers, and to Jennifer who made sure every step of the way made sure everything went smoothly.
The quality of service and follow-up is exceptional, I am very thankful for Seaport Windows and Doors. I will recommend them to any who wants quality and service that you do not find in others.(I would give 10 Stars out of 10 if that were one of my choices). Thank you once again.”

Michael A.

“We had a very challenging retrofit & more than 30 windows done by Seaport.  The problem we had was with the manufacturer NOT Seaport.  When Seaport finally received windows that were not damaged from the manufacturer the installation went quickly and smoothly.  We felt the pricing was about right for the amount of work required.  Ours was not a straightforward job and they pulled it off splendidly.  The true test of their work was with the amount of rain  this winter, we had with NO LEAKS or drips.  I really don’t think any other installer could have done this job. If you have a challenging job and want a professional experience, I would highly recommend Seaport Windows and Doors.”

“I have had a window problem with my older Milgard windows. Every time I have an issue I contact Alex at Seaport Windows and Doors at 4201 Katella Ave. Los Alamitos CA. He not only listens to my problems over the phone but he comes to my house no matter how small or large of an issue I have. I can’t thank Seaport enough, the people who work there are always very helpful and fast with a response. I’m glad to recommend Seaport to whom ever need fast and courteous service. Thanks Seaport.”

Mike S.

“All of the men that have come over throughout the month have been a pleasure. Jennifer is amazing and always on top of things. The doors are beautiful!

“Very professional. Left everything clean when they finished. Installers work on the clock so they take the time to do everything right. I’m really happy with my new windows.”

“We had an excellent experience with Seaport Window & Door. All of our windows were replaced. Thank you to Alex and his team; the windows look great. A special shout-out to Jennifer. She checked in daily to be sure everything was being done to our satisfaction. Great company to work with.”

seaport windows and doors; the right choice

For the average home owner, a window or door upgrade is typically considered a major purchase and the selection of the window and door dealer is extremely important.

At Seaport Windows and Doors our goal is “COMPLETE FULFILLMENT”, from the initial phone call to the final item of completion.   There are many very good window and door product lines available, but typically not every product line can fill the need, create value and exist within an owner’s budget.  To achieve “COMPLETE FULFILLMENT” we will recommend and provide the right product that will marry need, value and budget.

Our unit in Leisure World was virtually untouched when we bought it. We knew when we got around to replacing the entry and interior doors that it would be a challenge. Fortunately, we chose Seaport Windows and Doors. We are 100% satisfied with the outcome! Workmanship, hardware, and installation all exceeded our expectations. A year later, they are still checking up on us and sending someone free of charge to make any minor adjustments that are needed! We highly recommend their service and workmanship.

I love our new front door! It looks great! I love the glass and the design and the color. Thanks for working with us as I know I took extra time to consider choices. It was worth it, as the end result is perfect.
