If I could give these shady guys 0 stars I would. Homeowners beware! Not only was the installer’s work unprofessional and lousy, they left the house a mess without cleaning, leaving debris around the window and floors. Worst of all they damaged the molding and frame of the windows as you can see in the attached pictures. The sliding door was measured almost 2.5 inches short, there was empty space on the top section when they finished installation per the pictures.When we called and asked for the Manager to explain the problems and request fixing, they refused to take responsibility! We told them we will not pay the final balance until the installation is complete and they fix the molding which they damaged, which is warranted per the contract and under CA law. The response from John or David (Owner) was threatening, yelling and saying that if the balance is not paid, they will file a lien against the property. Given we didn’t trust them at that point and didn’t want them to make it worse, we were forced to fix it ourselves! I do not recommend anyone use these losers for your window work!

Great service, price, and product. I had this company give me the best price and also the best product. The installation crew was on time, professional, and hard working. They first took their time to lay down rugs and put plastic over everything that might get dirty. I was impressed with their work ethic and they fully cleaned up everything when they where finished. The quality of work was great. We love our new windows. I highly recommend this company to install new windows. From what I experienced, their price could not be beat and they use quality windows.

Great company to do business with. Great products. Professional crew and fantastic quality control in their installation. I got a few bids from some other places, even a company that I highly regarded with work I’ve had them do in the past. Discount came in with a lower bid, a better product, and with far better quality than I could have hoped for. They really won me over. Thank you all so much for the great work!

All individuals that I interacted with were polite and professional. They addressed any questions I had clearly and concisely. They explained the process necessary to repair the window and set the expectations when the work would be completed. The quality was excellent

Great company! They came in and did a wonderful job at installing our windows, and cleaned up after they were done. Thanks for the great installation. true professionals! i would definitely use them again

David showed up on time, evaluated the sliding door and recommend it be left alone due to the age of the door. We then asked him to give us an estimate on fixing 2 doors. He prepared the estimate and it was a fair price. He showed up on time and completed the work. He did an excellent job. We will definitly use him again and recommend him to our friends.

Very knowledgeable. The project turned into a complete door wall installation with interior finish work. David was very helpful in proceeding with the project. He is a real professional. Good work.

They were great. Finished all my projects in just one day. What a great surprise. They did an outstanding job replacing trim to match the rest of our house in one of our bathrooms. A job my former contractor said would be too hard and take too long. They did it no problem. I am Pleased to recommend to anyone!

Down to earth company. Reasonable pricing. Fast turn around time. The quality of the screen windows I purchased were good. I cannot complain because their price was competitive, they were quick and flexible. Overall, I am happy with the job!

David was an expert at replacing a pane; he called promptly, showed up at appointments on time and was respectful of property. It was a small job, but he treated it as important as a big one. I am planning more work with them!

I was very appreciative of the work they did and the information they gave me. I felt they went beyond the call of duty to make me happy. They were pleasant and hard working. I am so happy to have the windows replaced thank you very much Wintorium Windows and Doors !!!--

Excellent work, fair pricing, and an excellent team to work with. Very happy with the results, and even when we ran into an issue with materials (my fault) they adapted quickly and switched up the plan. I absolutely recommend them to anyone looking for a professional team

I was able to get a same day quote, and supplies were ordered with no money down. The supplies all came much quicker than expected and the job was completed quickly.

We hired this company when our business was broken into. They ordered our window that day and had it the next day. Very professional and fast. I would highly recommend them!

Very good! Made an appraisal appointment online. Arrived promptly. Very nice, very professional. Made sure windows would match ones put in by someone else 5 years ago. Day of installation: on time, great job, everything was cleaned up (no mess) Contacted us later to be sure we were satisfied. Very professional. Highly recommend.

The installers did a fantastic job! When they were done it was so clean. There was no indication they had ever been there except for the 2 beautiful windows they installed. I was very happy and I will use them again!

Very good experience with Wintorium Windows and Doors. We needed to get over 16 new replacement windows installed in our home. Shopped around quite a bit. Jhon came to our home and explained all our options & prices. We chose the Climate Solutions window series. The window installation took 1 and 1/2 days. Crew were very polite & cleaned up everything. The owner, David came to our house to make sure everything went smoothly. I would highly recommend this company.

Wintorium supplies a high quality product and excellent customer service. They work closely with the owners and our architecture firm. We are currently working with Wintorium on a project and look forward to working with them again in the near future.

Wintorium Windows and Doors is truly top-notch. Their team is extremely professional and dedicated to doing a quality job. We have done two window installation projects of significant scope with Wintorium. The installer was attentive and responsive to every detail. If all contractors provided this level of quality and customer service, home improvement projects would be much more pleasant to live through. I recommend Wintorium unequivocally.

Great initial consult with company representative. Costs and number of windows needed was presented. Myself and my wife did not feel as though we were pressured which allows us to make a more informed decision regarding windows for our home. Of all the products that we have looked at, the quality was indeed excellent and our windows came out beautiful will definitely recommend Wintorium Windows And Doors. Also, the warranty is a great selling point.

Recently received quotes and replacement windows from Window Design Group. David offered options and advice that were very helpful and made the difference with our choice. David and his installation crew were respectful and thorough.They were on-time, proficient, and worked with challenging issues. We appreciated their honesty, expertise and professionalism. We are enjoying our new windows, blocking out sound and energy efficient. Thank you David and crew!

Great people to work with did not have one problem from start to finish. My new windows look great and Very happy with the crew that installed them.

I called Wintorium Windows & Doors after searching and finding them online. What made me called them and find out about prices and delivery was the good financing available with no payments for 6 months and $0 money down. I placed an order for 20 apartment windows and 4 sliding doors, with the price set and the purchased done, all I had to do was wait for the windows and sliding doors to be deliver on time. Everything was on time, the building looks like new with the new windows and sliding door. The best costumer service, fast delivery and good prices. I highly recommend Wintorium Windows & Doors.

It has been a great experience working with Wintorium Windows and Doors, the level of service and quality of each product exceeds our expectations. Our customers have been very happy with the final product and the utility and usage of Wintorium.

Im so glad I contacted Wintorium Windows and Doors. We got custom windows for way less.David was always so responsive and professional. And the installers were on time, did a great job, and were in and out in no time!Highly recommended!

Cant recommend this company enough! Replaced a double front door (circa 1998) with a much safer and sexier model. There are a lot of details in replacing a door, and they patiently worked through every last one with us.The door fits fabulously (no gaps or drag), and the multi-locking hardware/hinges operate with smooth precision.

I hired Wintorium 5 months ago to install all new vinyl siding, 18 new windows, and 2 new rear sliding doors in a rental duplex that I own. I contacted several siding contractors for quotes, but none showed the enthusiasm that John did. John gave me several references to call and drive by, which I really appreciated. He also patiently answered all my questions and concerns prior to me giving him the job. I was very pleased by the quality of work performed by John and his colleague David. I am certainly not the easiest customer to please, as I believe in doing everything the right way and not to cut any corners. Wintorium did an excellent job. I have not had any problems with the work performed by them. All the windows and doors are still tight and the new siding still looks good as on day 1. I would not hesitate to hire Wintorium, and highly recommend John and his team.

What a great experience. From start to finish. They guys are experienced, didn’t waste my time and they knew exactly what to do.Windows look great. I finely can read a book without being distracted from the outside noise.It was a wonderful experience and I’m definitely recommending them to all my friends and family.

Excellent service and installers. Had all the windows in my house replaced. The foreman for my job was very conscientious to make sure I was completely satisfied with their workmanship. Very happy with our results. Highly recommend Wintorium Windows and Doors.

Love the new windows and they are so practical. Can feel the energy savings already

It has been a pleasure working with Wintorium Windows and Doors for several years now. They always stand behind their warranty and make a high quality high product in the industry.

We started a project, which was to remodel a home in Santa Monica... We search a few Windows & Doors distributors in Los Angeles to provide us with an estimate for what we needed, which was 14 windows, 3 interior doors & 1 sliding patio door... We call a few distributors but no one was able to provide an on-site estimate. We needed someone to come to the job site to give us a quote on the doors & windows we needed but no one was available until we found Wintorium Windows & Doors! This guys send an expert the following day we call them, the expert showup on time, he inspected the home & was able to provide us a free estimate on the spot. The price easily beat the competitors prices... so we went ahead & place our order with Wintorium... they deliver pretty quick, all doors & windows were deliver to the job site on time & without any issues like dents, scratches on the windows or doors... we are extremely happy & satisfy with their customer service, prices & the way they do business... next time, we now know who to contact.... Thank you guys, because of you, we were able to save more money than what we expected.... A+

Great customer service. I just love the that the staff actually cares. They made 2 screens for me made of cat claw proof material. Theyre great!

Absolutely impressed with the professionalism of the sales people in this company. Had two quote from different companies but the way they explained and work made me go with them and I m glad I did.Highly recommended

I found Wintorium Windows and Doors after looking for a while and comparing different prices from different companies & Wintorium was by far the best option. The website is amazing and easy to find the size or shape of windows I was looking for. I bought 8 house windows and a French sliding door. The price was good and the delivery was even better, everything in time. Highly recommended.

They replaced 13 windows throughout my house as well as installed 3 new sliders. They are great window contractors and did a nice job including all the patch work! Highly recommended!

I had an amazing experience with Wintorium Windows and doors. My new windows look great and were significantly cheaper than a quote I received from a different construction companies for the exact same windows! Their customer service was what really stood out to me though, it was outstanding...we had a small issue after installation and spoke with John. As soon as I made them aware of it they responded immediately with a plan to resolve the issue and took care of everything. A+

Fast, clean, and super affordable. Marcella gave me a price significantly less than other companies that I got quotes from. I was happy with their service. Windows are truly great.

Very good experience. They were professional all around, and the results were outstanding.They came out and provided an estimate, The guy was right on time and with minimal fuss and no upselling went to work measuring the windows. The price was reasonable and because of the politeness and professionalism of our first encounter, we decided to go with them and they did not disappoint the work was done very well within the given time frame.

By far the best experience I’ve had with a construction company, we had 10 windows replaced and 2 patio doors . Everything went smooth and we are very happy with the outcome !

Great company to deal with, nice and attentive. Pricing was competitive (I gathered quotes from 7 other companies) Got a quote right away. Luckily in my case the door I needed was in stock, so they were able to install it as soon as I was available.

We are very happy with the quality of the Milguard windows and the wonderful craftsmanship of the installers. David and his team did a great job installing our 4 windows and patio doors. They worked steadily and cleanly and although they arrived a little late due to traffic, they stayed until the job was done. We love our new windows. David even went out of his way to go to the factory to pick up the patio screen that they forgot to send with the order and delivered it to us on a Saturday. Great service!

I needed multiple windows replaced and they showed up in less then 24 hours. right in time for the city inspectors to verify they were working properly! Marcella was awesome! explained everything and got it done!!! Will definitely call them again for other future projects.

Thank you guys for your help with installation. You guys are amazing. The house looks incredible. Windows look great. We can hardly hear the outside. We are very happy.

Absolutely impressed with the professionalism of the sales people in this company. Had two quote from different companies but the way they explained and work made me go with them and I am glad I did.Highly recommended

Hands down the best company I’ve dealt with in my entire life. They installed a beautiful custom made entrance/ back porch door at my moms house and I just wanted to give them a good word here.

Great service and was able to replace 2 windows that no one wanted to do. Highly recommend for any window job. Very friendly and did an amazing quality work.

Thumbs up for these guys !!!I recently remolded my home and had new windows installed. I wanted big lavish windows in front of my living room area. Wintorium Windows and Doprs Came to my home took out my nasty old windows and installed the new set of windows.Would definitely recommend them to anyone!!

What a pleasure..Very professional process from start to finish. No hard sales, the product is beautiful and the install team was clean, courteous and efficient. Could not be happier. Thank you David !

I talked to some nice and helpful people here.

My whole experience with Wintorium was incredible. The workers who installed my windows were excellent. They were on time, professional, neat, cleaned up daily- worked very hard - courteous- Recommended!

They fixed my insulated glass in a timely manner, along with a few screens, for one of my properties. If you are a landlord or management company Wintorium Windows and Doorscan help you out. Thank you!

In a town where real estate is now the business model of the city and the advent of trying to find a good contractor or remodeling company whos customer service is still somewhat realistic and not an analog wave of rude behavior, ghosting, lies and forgetfulness my wife and I were actually able to find the proverbial needle in the haystack in regards to windows and window installation!Wintorium Windows & Doors here in Los Angeles were and are a very nontraditional respite. For instance, following up with us and giving us a great deal. Doing the job when they said they would plus free construction clean up after the window installation for our A.D.U.( Additional dwelling unit).We knew the windows we chose from them would be great therefor this review details the company itself and how happy we were with them. Needless to say this writ is in the positive but when good customer service and professional work are a rare commodity here in Los Angeles then Wintorium is itself a rare commodity.

Superb customer service. Highly Recommended

Just had all our windows replaced.... great organization, very professional, and polite. Highly reccomend!!!

Wintorium Windows and Doors are awesome. They replaces my son windowsIn his apartment in LA ( of course I had to payed for it ... ). Being far away ( Canada ) I was nervous about the outcome and the fact that I can’t see the work. Well they assured me everything will be ok and they kept their promise . My son told me there were always on time, cleaned up afterwards and even helped him move some furniture back. Thanks guys.

They are the best in Los Angeles for window repairs and fast service! They have the most reasonable prices around the area, and have great glass repairs.

Very satisfied with wintorium.They were easy to work with & Efficient.Technically (sound, heat, light), the windows are great. The installation is seamless and im very happy.

They did a wonderful job replacing all my windows. I truly recommend them.

They replaced all the windows in the building I manage. The windows work well and the installers were very clean in the occupied apartments. I will use Wintorium again and would recommend them to my other clients.

I would highly recommend these guys to anyone looking to get new windows.

I replaced my sliding door that was broken and these guys were all very professional and offered me what I was looking for as well as offered me different solutions that would benefit me based on the information I gave them.

Really good

Brittany Anderson is offering people like me $1 to post fake reviews for several different companies this being one of them so don’t be surprised if most of these reviews are FAKE! I have uploaded screenshots of our conversation of her offering me $1 to post reviews that she sends me.
