Rated 5 out of 5 by from Wonderful service! For our first time purchasing windows & doors, we could not have asked for a better experience. Mike was extremely knowledgeable about our options and provided excellent customer service. From taking detailed measurements to helping us select our trim options to an extremely efficient and clean installation, we are very happy customers. Would recommend Aggressive Sash & Door to friends, family, anyone!

Rated 5 out of 5 by from Exceptional Service and Work Product Honest, efficient and reliable- just a few of the words I'd use to describe Mike and his crew. From start to finish our experience with Aggressive Sash and Door was exceptional. We were clear about what we wanted (installation of 5 older windows to match those on the rest of the house), and Mike came out the next day (on time) to give us a quote. He did not try to upsell us and was very knowledgeable about the product and work to be done. Within the next few days, our windows were ordered and an installation date was set. On the day of installation, Mike and his workers were on time and finished the job quickly. We were so impressed by the quality of the job- our windows look amazing! I highly recommend Aggressive Sash and Door for your window/door projects- they are absolutely deserving of 5 stars!

Rated 5 out of 5 by from Happy customer We recently had a large window replaced by Aggressive Sash & Door. The effect on the insulation is excellent. Nice temperature and noice insulation. Mike is very good at explaining what the process is. The delivery and installation were on time. They did an excellent job and left the job site clean.

Rated 5 out of 5 by from THE BEST THERE IS I am a realtor and me and my husband own several rental properties . I started using Mike to replace all my windows and doors several years ago and he has done several homes for us including interior doors, hardware and exterior windows and doors. I recommend him to all my clients and I always get great feedback. Don't bother going anywhere else.I always use Milgard products too because they are the best and a local company also.
