Lynn and his crew (Pablo & Ricardo) were such a pleasure to work with. From beginning to end, they were professionals. Lynn was almost always available when you called (granted I had his cell number) and if not, he usually called back the same day. There was a miscommunication about the door we ordered, and a mix up with the windows, but it was brought to our attention immediately and resolved quickly as well. Lynn came to our home several times (mind you, he's driving from North Hills and we're on opposite side of town in Pomona) and we went over the contract, the details, and for the walk through with his concrete crew. One time he even stayed as late as 9pm to accommodate my husband's work schedule and to go over all the final details. The same professionalism was carried out by his crew, lead by Pablo and Ricardo. Pablo was in charge of the sunroom structure and Ricardo was in charge of concrete and electrical. They were one of the best construction crews we have ever worked with; efficient, diligent, and communicative. They weren't afraid to answer our questions and when something went wrong, instead of hiding it from us, they were very upfront about it and assured us it would be fixed right away. When the factory provided different windows, Pablo pointed it out to us and asked which ones we wanted to go with and that he was going back to pick up uniform ones. We couldn't have known unless Pablo told us or until we saw them later on. When we had to put the sunroom's electrical on a different circuit breaker on our panel (about 40 ft away) and metal tubing had to be used because it was run externally, without us asking at all but because they knew we were aesthetically concerned about the silver tubing looking out of place, Ricardo had his crew paint the tube to match our house. The previous owner painted the house and never left any paint so we had no idea what color it was, but Ricardo's crew went and matched it! They did all of this without us asking and didn't charge a single penny for this additional work. They even left the remaining paint for us so we could touch up other areas or just have paint color reference for the future. There were a number of other little things they did that restored our faith in contractors (e.g. helping my 3 yo daughter put handprint in wet concrete, removing a very small section of bricks and pouring concrete over it, coming back to diagnose a leak in sunroom that we weren't able to duplicate to this day, etc). Lynn and his crew were exactly as how other reviewers described, the traditional contractor that honors his word and delivers as promised. We were hesitant in the beginning because Lynn's price was so competitive (more than $10k below other sunroom contractors we talked to), but we are so glad we did. To sum it up, if these people are not your ideal contractor and crew, then don't bother calling these guys and wasting their time!
