Window Installation reviews across the US

After securing 3 estimates for replacing 9 windows and a door at our home, the staff at Window World best helped us understand how changing out our windows with their products would go smoothly and affordable. They walked us through the entire process, including payment. We went ahead and ordered the nine windows to replace our existing windows and a beautiful new door. The technicians were extremely professional, timely, industrious and cleaned up very nicely after they completed their work. I highly recommend Window World for your next window project. They are great!

We ordered windows from Window World on July 6, 2025 after an in-home meeting with their rep, Greg, attended by myself and my builder. We specifically asked for the lead time for our exact order, which included custom sizes and bronze exterior / white interior factory finish. We were clearly told that the expected turnaround time was 6–8 weeks from the time of order. Based on this information, we proceeded with the purchase and structured the remainder of our construction timeline accordingly.

Based on the stated lead time, our windows should have arrived by the first week September 2025 at the latest.

At approximately six weeks post-order, I attempted to follow up for a status update. Multiple voicemails were left over several days without response. About a week later, I was informed that Greg had been on vacation and that the windows were now expected to arrive in another 2–3 weeks, which still aligned reasonably with the original estimate.

However, after that point, the communication deteriorated significantly. At 9 weeks post-order, we were told “hopefully next week.” This same message continued for another 5 weeks, despite repeated follow-ups.

On November 3, I left another voicemail. Greg returned my call on Nov 5 and stated the following (paraphrased):

“Normally standard white windows are 6–8 weeks. Once you get them painted or colored, they have to ship them to another plant to get painted, and it takes longer—usually about 10–12 weeks.”

This explanation was never disclosed at the time of sale, despite us asking specifically about lead times for our chosen configuration. Had this information been provided upfront, we would have made a different purchasing decision or adjusted our construction schedule accordingly.

Ultimately, the windows were not delivered until November 9 — approximately 16 weeks after the order was placed, more than double the original quoted timeframe (and beyond the timeline even IF they had given the 10-12 weeks
in the first place)

Key Issues:
1. Misrepresentation of lead times when directly asked about this specific order configuration.
2. Failure to return calls and provide timely, honest updates.
3. Repeated assurances that delivery was imminent when it clearly was not.
4. A significant domino effect on our construction schedule, including delays to drywall and finishing work.
5. Substantial financial impact, including:
• Delayed move-in from Christmas to March/April
• Additional months of rent while simultaneously paying a mortgage
• Thousands of dollars in avoidable costs caused by inaccurate and misleading information

I fully understand that delays can occur in construction and manufacturing. What is unacceptable is intentional or negligent misrepresentation, compounded by poor communication once the sale was secured.

Had Window World been honest about realistic lead times—or transparent once delays became evident—we could have planned accordingly and significantly reduced the financial and logistical damage.

This experience reflects a breakdown in honesty and accountability. I am documenting this not only to seek acknowledgment and resolution, but also so that future customers are not placed in the same position.

Wonderful experience! Love my window! Kevin gave us quote arrived 6-8 weeks later!The installation was great they cleaned up after themselves left no mess! Lifetime warranty! Another copy from Knoxville told us all three windows had to be replaced due to warranty that was untrue! The price was very reasonable! I would recommend Window World to everyone!

Nothing but the Best. The crew that came out and installed our windows was great. They worked diligently to make for a smooth transition and were very knowledgeable in what they were doing. Thanks for a great experience. Highly recommend Window World of Knoxville!

Our installation went wonderful! Johnny Bell did an awesome and amazing job, very much a perfectionist and we are extremely happy! From 1-10 I rate his work a 15!

I have used Window World several times. Their products are superior and their employees are much better. We just had a patio door installed from our living room to our enclosed sunroom. It changed everything for us. With a sleeper sofa, it turned the room into a 4th bedroom for guest and the door provides privacy and a noise barrier.

110% satisfied with the job done by window world and there installation team. The crew arrived slightly ahead of scheduled time, after introductions they immediately started working. Within 4 hours all of the old windows had been removed and the new one in place. We also had 3 entry and 1 sliding patio door replaced. By the time they left day one the job was 75% completed, returned the next day finished. All old windows and scrap from new was picked up and hauled off. Except for the new look and yard sign you can't tell they have been here.
The crew was, friendly, professional, well organized and very proficient at their jobs.
I have zero hesitation about referrals for window world. They did what said they would. The quality and craftsmanship is excellent. It is a shame you can only rate up to a 5.
Window world was not the cheapest nor the most expensive, they fell in the middle of the price range, very happy with the final product.
Thank you for an excellent customer experience from the beginning to the end.

Window world came out measured and placed an order. They arrived quicker than originally estimated. Super easy installation and entire window sill outside was wrapped with coil stock. The installers were careful with the plants in the flowerbeds below the windows. Super happy with entire process.

Absolutely the best home reno experience my husband and I have ever had! Cant wait to replace more windows in the future! VERY professional. Left no mess. Johns finish work was impeccable.
THANK YOU WINDOW WORLD! We will see you again

The Window Source was the right choice! Relatively small job with only 4 windows, but I did get 4 estimates and The Window Source Beat and exceeded the rest in cost and quality of product and I think customer care! We had a great experience from the first visit with Anthony and then Rich, and it was always a pleasure speaking with Brianna. The installation went flawless! They are a well oiled machine that arrived at 8 am were finished and cleaned up shortly after 10:30 am I was amazed! We are very pleased.

The Window Source RI did an excellent job at my condominium. They offered a fair price and the finished product looks fantastic. I’m very happy with the results.

I am very satisfied with 5 new basement windows that were installed today (June 30, 2025). The crew led by Joe Perto were on time, efficient & courteous. Although my house is 120 yrs old with an old foundation, the lead man, Joe, was careful to make sure the windows were secure and leakproof.
The only complaint I have is that the indoor cleanup could have been better.
I would not hesitate to recommend Window Source.

Bob and crew did an incredible job on my windows. They were so fast! The whole experience with window source was great. So easy and stress-free. I would definitely recommend them.

The whole experience from start to finish was easy and professional. The installation crew was great and neat never even knew I had bow window replaced would definitely recommend.

I had reached out to multiple local window companies and by far The Window Source RI were the most Professional and Experienced. With over 25 years of experienced installers, I am very pleased with their installation services. Eric, Kevin and Cappy: Thank you for your services! The office staff are amazing too! I love my new windows! The owner Richard even came by to inspect the job. I would highly recommend Window Source Of RI to family & friends.

We just had 16 windows installed, done in under 4 hours! Bob and his crew were extremely efficient, everyone knew their individual roles during the entire installation, and they all combined to do a phenomenal job! We are completely satisfied with the whole process from Wayne coming to quote us to the end product. Highly recommend Window Source of RI.

From initial visit and measurements, to installation completion, all very professional. Very satisfied with work. Installation crew was timely, work done to specifications and clean up was thorough.

The crew that came Sal, Dylan and Jess were totally respectful, neat and cleaned up really well after they were done. The windows are beautiful and I would recommend Window Source highly. Very satisfied. Windows were cleaned before they left which saved me work. Owner came and checked up on progress of installation, which was great.

Bob and his team were great. They did quality work, were pleasant, and answered all our questions. We’re very happy with our new windows!!

Terrible!!!

If you’re not interested in reading my whole review, I would summarize my experience by stating the window install from Window Source RI was unprofessional and sloppy. If you would like to understand why, please continue reading…

In the summer of 2020 I did a lot of research before selecting Window Source RI to replace by 6 basement hopper windows. Window Source RI had fantastic reviews and reasonable prices. They did not have the lowest price, but I assumed it was worth a bit more money to work with a reputable company with a long-established history and very positive online reviews. I am honestly shocked that the same company that installed my windows is associated with the near 5-star rating on Google. I wanted to share my experience so that others would be aware of the risk of a not so great experience.

The install team came in after completing multiple other jobs earlier in the day and were in a rush to get my job done and finish their day. They rushed the job and it showed. They broke 2 of the 6 windows during my install. 1 had broken glass and 1 had a broken frame (both from being dropped). Broken glass was left everywhere. Adhesive was left on the walls, floors, yard, washer, dryer, foundation, etc. The dryer vent in the window was misaligned and unusable. The dryer vent tube was broken and damaged beyond repair. I had to purchase a new dryer vent and repair their sloppy installation of the dryer vent. I also spent hours scrubbing the adhesive left all over my house.

I was told my 2 broken windows would be replaced within 1 week, but it ended up being about 8 weeks. The replacement windows went comparatively well. The windows were not damaged. A bit of a mess was left this time too, but not nearly as bad as the previous time. During the review of the install, I noted that 1 of the screens was missing (both most have actually been missing). They said they would add the screen on the way out. I went downstairs to check it out and realized the screen was still missing. The screen on the other replaced window must have been added, but the window I originally noted as missing had not. I ran upstairs to see if they were still outside in their truck. They had left but I saw them driving down the road a few houses down. I called them about the screen and they said they would turn right back around. After waiting outside in the cold for 15 minutes, I began to lose hope. I called the installer team member back and went straight to voicemail; I assume my number must have been blocked. I was already quite frustrated by all the shortcomings of the install, but lying to me about returning to my house was the “cherry on top” in terms of being completely unprofessional. I have no idea why you would tell a customer that you’re heading back to address an issue and then drive away. I called the owner and a screen was delivered to my house the following day.

As if the install issues weren’t bad enough, the quality of the windows is somewhat suspect. After a couple of months with the windows installed, I noticed dirt on the window sill. I expect the dirt ended up on the interior window sill as a result of dirt splashing up on the window during rain storms. I would expect that new windows would not allow dirt to come through. I’m not sure if this is inevitable with hopper windows or a function of poor manufacturing.

All in all, quite the disappointment. I would not recommend Window Source RI to anyone looking for a quality window installation.

My daughter's condo only has 2 windows and they needed to be replaced. Excellent company from the first phone call. Walked us through everything. Very supportive throughout the process. High quality product. 10/10 recommend.
