"Had the pleasure of having Sal install and replace 3 exterior doors and 2 storm doors. Very detailed, skilled, knowledgeable and professional with his craft. Will continue to use his service and recommend to others."

"They replaced my bathtub, installed a new vanity, put in new lights and painted a wall cabinet. Not only were they punctual, but very polite and reasonable. I highly recommend them and will use them in the future."

"Very professional. Came over promptly to give an estimate. Arrived on time to do the installation. Did a great job! Totally happy with the work."

"We've never had luck with major home modifications—this was smooth sailing the entire way. Our project was a teardown and complete re-side, and Cocos did a fantastic job. We have a tricky home with a lot of angles that make no sense—Cocos did a brilliant job strategizing how everything should be executed, and the 50-year-old home looks brand new. Danielle, Keith and Matt not only executed at the highest level, they stayed in communication literally every day to make sure there were no surprises and that we were happy with the progress. If you're looking for a home siding partner, don't hesitate to hire Cocos. They were top notch and we are very happy/"

"A job well done, punctual, they cleaned up."

"Brandon does excellent work! He’s friendly and professional, his prices are very reasonable, he cared about my project, offered suggestions and showed up and finished when he said he would! I recommend him highly!"

"These guys are fanatic. We were having a renovation done. Our contractor discovered we were getting water in by our old French doors. Due to the unplanned replacement, we needed a door on very short notice. We didn't want an out of the box from a home improvement store, so we saw Royal Windows and doors. Danny was able to accommodate the timing which wasn't easy (the doors are built to order) and expedited installation. Within two weeks, our new 12 ft. Sliding door was installed. The door is great quality and it looks absolutely stunning. Royal really came through for us. 10/10 will use them for any doors we need in the future."
