"Quality of workmanship was excellent and pleasant to work with. Was flexible with changes and creative in solving construction problems."

"Very good service only did the work I ask for and help in doing the install at a lower cost."

"Jose was friendly and professional. My job was not considered large by any means (re-hanging a gate) but he completed it in short order and cleaned up after himself. I really appreciated the fact he wanted to insure I was satisfied with the work because he needed to cut an inch off of the gate.....which I was. I would certainly call him again."

"The contracted the work off to a third party. Jon took longer than expected. The windows was installed pretty good from the looks. Communication could have been better with knowing the job will take longer and what types of trims I wanted for the windows. As the contractor that was hired for this job by this company. Did a good job with putting up decent trim. As for the new windows they look great. I purchased the myself and hired sentri homes to install them. I will need to have a my siding on my house redone to be closer to the new windows so the gaps are not so obvious. That was not expected at first. But from old storm windows and not knowing how they were put in originally. There was some unknown things that was learned from the job being completed. I will have the siding of the house slightly done to match really good for what I wanted later on. My only concern is better communication with sentri homes. Overall they were great when I did talk to them."
