Turned out to be one of the best decisions we ever done. John is the man. Not only he explained everything at the jobsite, but he also showed us the mechanics of the windows and doors at their showroom. Maricar scheduled the mobilization and everything was perfect. Thank you so much Frontier!!! We'll see you on our next project.

It was super easy to schedule them. They came out to measure & then came out several days later once the replacement glass was ready to do the install. Left no mess behind & final charge was the same price as they originally quoted. Can't argue with that!

It's been over 3 months and I've have been chasing Romeo (our sales associate) and the ordering department for an update, and haven't heard anything back. Next step is to file a claim against the company. Wouldn't recommend Sivan windows and doors to anyone looking for a professional experience.

Michael Crooks was very responsive as a company rep and everything he quoted was delivered just as he said. The quality of the shower is excellent and we love the Koehler fixtures. We chose black on white to assist those with visual deficits and really like how they turned out! The fold down seat is also a plus for those with endurance challenges! The demolition andinstallation team of Jose, Gabriel and Jairo could not have done a better job! They were timely, efficient and professional. They demolished the shower and tub one day and took away all the debris. Then, the next day, they built the frame and installed the new walk in shower exactly as we requested. They were pleasant to have on our property and we're considerate in where they set up their workstation and parked their trucks. We did have a challenge posed by the installation day with company coming to visit us... And they worked out a mutually agreed upon date that met our needs. I highly recommend this company.. ask for this team of installers! You won't regret it!!

They were quick about the work- even over a holiday weekend. Everyone I spoke to was so friendly, very accommodating, and respectful. We 100% will use them again if we need it and recommend them.

It took 6 weeks between the agreement signed and the completion of the project, mostly due to delivery of the windows ordered. Very impressed by the efficiency of the crew that installed the windows. The windows were installed in half a day, including 3 of them on the second level. All debris were cleaned up. I had windows done by another company before and there is no comparison. I wouldn't hesitate to hire them, they are pros and they go above and beyond.

We were initially a bit concerned about moving away from custom doors, but we chose the wider bevel option, and they look great. We were very impressed with the efficiency and installation of their product. Nine years later, these vinyl sliding doors have had no issues, aside from tightening the handles once. They weren't the cheapest or the most expensive option during our research, but they've proven to be reliable and well worth the cost. Recently, we needed to repair one of the screens after our pet ran into it, and their team was very accommodating in helping us out. The staff, especially Heather, were friendly and a pleasure to work with. Thank you!

One company didn't even bother to come out--just asked for measurements and sent a generic quote for basic Milgard windows. Another contractor did show up, but he was extremely pushy and basically demanded that I make a decision on the spot. He was also the most expensive of the three. Approved Contractor was the complete opposite experience. Their sales rep came out, took his time, was very relaxed and professional, walked me through all my options, and provided full license and insurance info. He left me with a written estimate and zero pressure. Their pricing came in right in the middle, but the service level made it the best value by a mile. Once my HOA approved the project, everything moved exactly on schedule. The windows were custom, and the team showed up within the four-week lead time they quoted. They installed all five windows in less than a day. They also removed the brand-new blinds I had just installed and put them back up perfectly--like they were never touched. Huge bonus. Communication was great the entire time. The installer met me in the morning so I could walk him through the space, and he called ahead before finishing so I could come back from the office, inspect everything, and sign off. The finished product looks fantastic. From the first phone call to the sales visit to installation day, the whole experience was smooth, honest, and professional. I'd absolutely recommend Approved Contractor Inc. if you're looking for quality window replacement without the pressure or runaround.
