What Customers Say

  • I highly recommend Coughlin. They did a big sliding glass door to our home and the experience was PERFECT. Not only did they have very competitive prices, they know the window and glass door business exceptionally well and pointed out options and concerns. They remove all the old door, took it away, installed the new one, fully cleaned up the area till it was spotless, and then spent time showing the locking features of the screen as well as the sliding glass door. It couldn’t have been a better experience!

  • We had Coughlin Windows replace all the windows and patio doors. They sent 3 crews and it took about 6 hours. They were very respectful of our things and put down covers to protect the carpet. They vacuumed each area after the installation was complete. Also I’m so impressed with the blinds being reinstalled. They seem to be cleaner and work better than before they got here! The whole process from measuring to installation was very smooth. Highly recommend!

  • Coughlin did an outstanding job of installing my windows. There were on time, they did what said they would do the first time and most importantly communicated clearly with me. I’m sure I will be a returning customer for future projects.

Frequently Asked Questions

Many one-room window replacements finish in a day; larger homes or mixed window/door projects may take more time. We’ll provide a clear schedule before we start.

For like-for-like replacement windows, permitting is often straightforward; new openings or structural changes can require approvals. We’ll advise based on scope and local guidelines in California.

Vinyl gives strong value, fiberglass supports larger panes, aluminum creates narrow sightlines, and wood offers classic warmth. We’ll help you find the right balance of look, durability, and performance.

Modern insulated glass and tight air seals can reduce drafts, stop hot-cold spots, and make rooms more comfortable—especially in coastal zones.
