Aggressive Sash & Door is rated 5.0 out of 5 by 29.
Rated 5 out of 5 by from Excellent knowledge of the product and exceptional installation. I used Aggressive Sash and Door to replace all of my windows down at the beach. They quoted me a time as to when I could expect the delivery and they were dead on. They also finished right when they said they would and their knowledge and the professional installation job that they did blew me away. I will be using them for all of my window needs in the future.

Rated 5 out of 5 by from Dealing with the best has its rewards. I have had the pleasure of dealing with ASD for over 8 years. A very professional group that do what they say when they say it. As a general contractor it is very tough to find good vendors that make you look good to your customers. In ASD 's case, thet are a cut above good, they are consistently great. I wish I could speak as highly about all my vendors. I highly recommend ASD for all your door and widow installation needs. Even if you install yourself, you won't find more competitive pricing on material.

Rated 5 out of 5 by from This dealer went out of his way to help us! We would absolutely recommend this dealer. The person we dealt with was very responsive whenever we had questions. We didn't feel pressure to make a purchase. Our representative showed us different options of windows and explained the differences so we could stay within a certain budget. Our representative was here to ensure the team was here on time and understood the job while making us feel very comfortable. The team that installed our windows asked where we would like them to start. The team worked hard and fast. They finished early and installed all 13 windows in one day. They cleaned up after themselves and were very respectful and professional while they were here. We had no issues with our installer from start to finish.

Rated 5 out of 5 by from The dealer is honest and punctual and does high quality work. The dealer replaced all of the windows in my two story home. The installation work was performed in a very professional manner. The pricing for the work was very reasonable. The sales representative and the installers were both punctual for appointments. I had a great overall experience and would highly recommend this company's work.

Rated 5 out of 5 by from Aggressive is THE best! I have used Agressive Sash and Door on about 10 projects of mine. Mike Frisoli and his team never let me down. If problems arise (which are seldom), they solve it quickly. Pricing is always highly competitive. I trust them completely and am delighted to give this review.

Rated 5 out of 5 by from GREAT SERVICE! After interviewing several window companies, we decided to go with Aggressive Sash and Door because their manager, Ernie Martinez was so knowledgeable and responsive. No big sales pitch, just good old fashioned honesty. We had 17 new replacement windows installed and couldn't be happier. Ernie made sure his team was ready to go on time. The crew worked together like a well tuned machine and finished the job 2 hours early without a hitch. Every man on the job was a Pro and very polite. We even recommended them to a neighbor who was equally satisfied. Highly recommend this service.

Rated 5 out of 5 by from prompt, courteous, quality service... We had doors and hardware installed throughout the house. The work was done quickly and most of all neatly. We did not have to do any cleanup. From the time we got the estimate to the completion of the job was the shortest possible time. Every one of the crew members that did the install were so courteous and customer service oriented that we felt completely comfortable with them. Overall, this was one of the best experiences we have ever had with any house improvement/modification. All of our special requests were fulfilled and all of our expectations were exceeded. The best part is that the entire job was priced within our budget.

Rated 5 out of 5 by from Great vendor. We ordered custom sliding doors for our office building and the folks at Aggressive helped us with the design and installation tips at no extra charge. The doors turned out great and were delivered earlier than promised.

Rated 5 out of 5 by from Great job in every aspect I contacted Agressive Sash and Door to do all my windors and doors in my Bell Canyon home. Over 30 window, 6 sliders and new front door. Not one thing went wrong. Great responsiveness from the original meeting and quote, through completion. They were on time for everything, and did extreme quality work and care. I felt like the installers were installing at their own house. I have recommended Agressive to many of friends who have all had the same experience. These are good people!

Aggressive Sash & Door, in Canoga Park, offered great solutions at a very competitive price. The estimate was done quickly, the selection was great and the install was painless. We love our new windows, they make the house!
