Just had all the windows and sliding door replaced by Window4u, and it was one of the easiest home improvement experiences I've had. Their pricing is very fair, and Alex and Leon were not only professional but incredibly efficient. Great team! Alex always replied promptly which made communication so easy throughout the project. The entire job was completed in just a day and a half. Much quicker than I anticipated. The experience was so positive that I am already getting another quote from them for another project. Highly recommend them!

Thank you so much, Alex and the Windows4U team. I had a problem with a sliding door on a balcony that was leaking water beneath it. Other providers didn't seem as interested to diagnose the true issue, and just provide replacement quotes - but Alex spent the time with me to check out the door, and point out signs where it was installed incorrectly or causing problems. This gave me the confidence to go with Windows4U and accept the bid, which was reasonably priced.

Within a few weeks, the new door arrived, and Alex promptly setup an appointment for the work. They installed the new door perfectly, and spent time to confirm the problems they found, and what they solved (flashing, etc.), so future leaks would be prevented. Afterward, my wife and I immediately felt the different in the room - we didn't know we had a light draft, but now it was definitely sealed tight. They also did a great job cleaning up the area and making sure they didn't leave any screws or sharp pieces behind (this is very important to us since we have pets and kids, and not every contractor is as tidy)

Overall, it was a great experience that built trust and confidence. I'll definitely be calling Alex again with any window or door needs in the future. Look no further.

I recently had new windows and a sliding glass door installed by Windows4U, and the experience was excellent from start to finish. Alex and Leon provided a free consultation, were extremely knowledgeable, and never pressured me into a sale.

Alex was my main point of contact and was always responsive and clear with communication. Everything that was promised was delivered as agreed. On installation day, both Alex and Leon were on site and brought in two crews to complete the job efficiently before the rain started.

The crews were professional, respectful of my home and family, and did a thorough job cleaning up afterward.

I highly recommend Windows4u to anyone looking for honesty, quality work at a fair price, and excellent craftsmanship.
