Cornerstone Home Improvement

I love these guys! They are prompt and courteous. Prices are very reasonable compared to other companies.

They were very good. The windows are working out fine for me.

(also see my previous report for this same company last year). 'Been assisting my brother with contractors for purchase of his home and remodel. Knowing how happy we were with Cornerstone, 'was unnecessary to obtain other bids for his nearly whole-house window replacement. Meshelle came out a time that worked for both my brother and me. Again, no pressure sale! Just like last time, she made sure to understand our budget, our needs, and offered all styles/options within. She was honest to say that three of the newer windows by the previous owner were good quality and didn't need replaced. Meshelle also mentioned that the window in the shower needed to be tempered glass for safety, if replaced (we did). Our bid was priced per-window, in case full 20 was too big a bite at once. She accomodated our special circumstance and communicated by email, always available for questions by phone too. In the end, my brother went with their lowest price point. But understand that even the most affordable windows by Cornerstone are better than any upsales by other companies, by far. I do know: went through several of those competitive, exhausting sales pitches last year. Because this family owned company prides themselves in great products and customer satisfaction, they do not offer what they won't put in their own homes. And they are not single-brand loyalbut have a business relationship with various manufacturers. The windows are not stock --Cornerstone remeasures each window to fraction of an inch when you contract with them, and sends the order to manufacturer. Turn around time was less than 8 weeks, probably much less, as I cannot find our info right off hand. The co-owner installed in less than two solid days; very personable and professional. Our inside window casings are still originals (might paint later down the road), but the way that the windows are installed, they look seamless against the jamb! The install, wrap, cleanup, and disposal immaculate! Went with solid white outside wraps, though color options were numerous. These windows are beautiful! They are great quality, and Cornerstone's product and installation warranties are rare if not exclusive in the industry. Another point I'll put in this review, is that properly frames/sealed installation is just as important, if not moreso, as the windows themselves. I discovered Cornerstone through an independent Home Energy Auditor that I hired over a year ago: Mary English with Small Steps Energy Solutions. As an aside, at my own home, my dog tore a couple of our screens right before my brother's install. Cornerstone rescreened them for a reasonable fee. The screens Cornerstone uses for every window are not plastic and will not be eaten by insects, as some products on the market. Finally, the company offers a list of homes for your area if you're interested. If you swing by to look at mine, the dust and water droplets are no reflection on their workmanship, ha! Check out their website, and in the end, know you'd be hard pressed to find a better managed, stand up company anywhere --yet thankful they're right here in Kansas City!

My experience with this company was wonderful. This is a family owned business that has been in operation for several years. The salesman was thorough and pleasant with the explanation of work to be done. The owner and his son actually did the work themselves. They were very efficient and I have received compliments on the windows from other contractors.

Windows crew showed up before expected. Not a problem and glad to have that part the job started and finished early. Scheduler for siding installation called when materials arrived shortly thereafter. Siding crew showed up and started the job, working every day until dark. They had to take one day off (a Sunday) because they ran out of J-channel. Not a problem, either, as it rained all day anyway. They returned Monday morning and completed the job. The lead crew man was very informative, answering all my questions and doing over a few minor mistakes to my satisfaction. The house looks great and we are very happy with Cornerstone for the overall job. We would recommend them to anyone.

This was an extremely smooth project from start to finish. The sales representative was professional and informative, but not at all pushy. I was also very glad to work with a local, family-owned company. Installation was quick and efficient, with virtually no disruption to our household routine. The company’s responsiveness and attention to detail were top-notch, from the initial bid to follow-up after the job was done. You could certainly pay less for replacement windows and doors, but I can't imagine getting a better value for my money. I will certainly use CHI for future projects.

A A+ job all the way around.. This company is one I would reccommend. I later learned that a neighbor had this company install windows also several years before my installation and were just as pleased with their product. The KEY to my satisfaction in this process of having windows replaced was the research and interviews, not giving into pressure and gulit from salesmen, learning about the different products available, and understanding what I was looking for in energy efficientcy and style or look of windows. I can live with these windows for the rest of my life in this home.

Cornerstone was the only installer that we got an estimate from that installed Soft-Lite Imperial LS windows. For these high quality vinyl windows the estimate was a very good price, when compared to estimates we got for lower quality windows. All windows were air tight installed in one day with trim work finished up the second day. Their service and products were outstanding. One thing that set Cornerstone apart, was a comment the owner made when we were getting our estimate. We asked if we needed to pay any of the cost in advance for the windows, since they are all custom ordered. The response was, "No, we don't believe in the customer paying until the job is completed to their satisfaction.". Following the installation, Cornerstone made a courtesy call to follow up with us, to ask if we had any questions or concerns and to thank us again for selecting them.

The project went great. The door was installed quickly with minimal mess. They were unable to reinstall my storm door due to no fault of their own. I'm purchasing a new storm door from them too. They have excellent products and do a great job. A very professional company.

A very profession contact with them. Some great information received. They could have been a litle more punctual on getting back to me.

They were efficient, careful and courteous. Sales person that gave us an estimate explained things well. First day had multiple crews here that were able to break down the work by areas (basement, first and second floor), and get all the windows installed. Second day, a single crew showed up to do the final detailing. When one minor problem arose, one window was the incorrect design, they took care of the problem within days. Also, a few of the screens had minor damage, but they fixed those and made sure everything was cleaned up. Only minor quibble with the windows is with the ones that have the recessed locks. Too easy to have those in the wrong position when closing the window, which can bark up the frame, but getting used to them. Also, since they slide fairly easily, sometimes have to hold the upper window while close the lower window so they line up properly when locking. However, all the windows are well made, and we can certainly tell the difference in insulating quality from our old wood frame windows.

They will be doing our windows on an order. It is family-owned business, and the daughter came out. We were very pleased. We would recommend them. They did a good work.

Seamless process, start to finish. See my review above.

We live in a 70 year old house. Some windows have been replaced by other owners. We had many more shabby, leaky windows and wanted to replace them. This company had good Angie's references and a good offer for individual window replacement costs. A salesman came to our house to give us an estimate. My major concern - beyond workmanship - was the quality of the windows - most particularly - would they prevent fogging? I asked the salesman, and he said they had a 100% guarantee of replacement if fogging occurred in the first 25 years. GREAT! I used to work for a commercial rental firm, and fogged patio doors and windows created horrible problems for us and the residents. To make a long story short - there were hiccups in the installation. Oveall, we got a nice installation, but it took five times as long as promised. Then we got the warrantee - and the windows are not warranteed for fogging. YEEEGOSH! That is such major issue. What liars!!!!!!!!!!!!!!

They did a great job, no mess inside and cleaned up the outside before they left. We are going to have the rest of the windows in our house done. We got a phone call from the office after they finished to see how every thing went. We love our windows and they make our house look much better.

They were very clean and effecient and I feel like they saved me money this winter. I have used them since to replace my lock. They came out on a Saturday so I wouldn't have to take a day off work. They are punctual and very easy to work with.

The man who came out to do the estimate was very professional and gave me a lot of information in a way that was easy to understand. They had a lot of different price options and even the product with the lowest price was a lot better quality than others I had seen. They worked with me on the price when a competitor was considerably cheaper (but much less profesional). They even held the price for me even though I couldn't afford to pay for it until 2 months after the estimate. It all seemed absolutely perfect until I started trying to put trim on the windows and found that the depths of the windows were all different, even on opposite sides of the same window, as much as a quarter inch on the same window and up to 1/2 an inch between 2 different windows. That's making it really difficult, since I have to custom cut each piece.

Got several estimates for window replacements. I did my homework and found that the Soft Lite Imperial LS Window is one of the most energy efficient windows on the market. Only Cornestone carries them. They also had the best price, and best warranty of any competitors. The salesman was professional and not pushy. The installers were professional and did all I asked of them. They required no money down, but payment in full upon inspection and completion.

I had three companies and a private contractor make estimates. This company is a family owned business. They came to the house and explained what would be finished and any special changes to the standard contract was made which included: a better insulation; all shakes removed; one new window had to be reframed to become larger; one new window built into a wall where there had been none. Overall, was pleased with their work and responsiveness especially management. One special size window was replaced as it had been made with dividers wrong. The windows and the siding were made by Reynolds. No aluminum but vinyl.

I like that it is a locally owned company. I know other people that have used this company and liked them. I thought the price was competitive.

My experience with them went fine. They were responsive and were on time. They were very good.

We are pleased with their work and their price. There were two different crews that came out for windows and siding. They were very good and we didn't have any problems with them.

They did everything in one day. Job was completed as outlined in estimate. Very good work and I would recommend them to anyone looking for replace ment windows.

Extremely excellent. The estimator came out and was here at the point in time that he was supposed to be. I'd tried another company and the guy showed up an hour late and didn't bring anything with him. The Cornerstone sales person had the model with him and all the information together, and then they ordered the windows. Two installers came and it only took them four hours to install six windows, which included wrapping the moldings. The windows are excellent. They did a great job of installation and they were about 40% cheaper than anybody else. I would use them again in the future and recommend them to others.

The salesman was prompt, courteous, professional and knowledgeable. I didn't use them because their prices were one of the highest that I received.
