Cornerstone Exteriors Services Inc.

Had hail damage to my roof and a tree limb fell and crushed a small portion of my gutter. Cornerstone was doing work to home across the street from me and I called the number listed on the yard sign that they pull in front of that house. Representative from Cornerstone, Bill Jew, came out and estimated the project (about $9,000) and handled submitting the claim to my insurance. Got approval from some of what his company proposed and I cut them a check in early fall 2016, Was told that it was too late to do work for the season (saw them work on other home in the area for an additional 5 weeks) and that I was slated to be the'first one to get project worked on come spring'. Spring 2017 comes and I see houses in the area being roofed and call Bill Jew and ask when I can expect to have the work done on my home. "Too cold for us to work until it is 50 degrees and warmer for the whole day and night' was the initial response, then 'oh there was a disaster in the Union IL area and I am busy there, will get to you soon!', and then it was "we are so busy that we are working on the backlog of clients!' and then in JULY 2017 they do the work, well not CORNERSTONE, but a crew of sub-contracted people who did not want to talk to me or answer questions in any way except to say "call Cornerstone". These guys were large men (over 6'4" and 250 pounds or more) and they RAN from one side of my roof to the other for two days. When they brought bundles of shingles to the roof they threw them like they were shotputs and the result of all this was that they put a crack in the interior ceiling of my kitchen that is about ten feet long and cracked all the drywall around a skylight. They also places a LEAD BOOT over the PVC radon emissions stack on my roof that is 100% AGAINST CODE ON THE LOCAL, STATE and FEDERAL LEVELS. When CORNERSTONE was contacted they sent the salesman, Bill Jew, out to address the problem. His solution was to personally patch the drywall on the ceiling (do not think that he is trained or qualified to do so) in such a manner that my eight year old son asked why the guy would waste his time to smear goo on my ceiling in a way that definately will have to be redone. Call after call after call to Bill Jew go unanswered. Calling the office is futile since they schedule an "appointment for our field supervisor to come out and fix it right away!" only to sit waiting fr this person to so up and no one ever arrives, When called, no one knows anything about it, or the damage to my home or person that is to fix it......but they sure know to remind me that I still owe them $4,000! (which I cannot pay in good conscience since the project is not complete and I am certain that if they get another dime out of me, then I have NO chance to get this resolved) They keep having a 'public adjuster' try to bill my insurance company for additional things, including the cost to repair the damage that CORNERSTONE did to my home. What they originally quoted $10,000 for they are now at about $18,000 claiming to my insurance. (which I have advised to NOT pay or respond to) All in all, going on two years since I originally contacted them and I am at the point in which I am going to have the radon stack repaired by a REPUTABLE ROOFING COMPANY and have a PROFESSIONAL PAINTING CONTRACTOR repair the damage to the interior ceiling. hhhmmm, maybe I will see if I can hire the most expensive contractors I possibly can since I am just using the money that CORNERSTONE would be getting if they fixed it. Wonder if it is going to cost a few grand to repair this stuff. WORST COMPANY THAT I EVER USED!!! NEVER USE THESE PEOPLE!!! UNPROFESSIONAL, SCAMMERS!

It took a while to get started, which gave us time to figure out what we wanted. They were good at explaining everything to us. They followed up and got the work done, cleaned up and everything went well.

Mike Panzarella was our contact. Phenomenal communication, overall wonderful man to work with- incredibly responsive and super friendly. Mike knows the industry and products very well. The crew was incredibly professional and quick! When they did the roof, I left for a chunk of the day, came back in afternoon, they were still working, and a half hour later they were COMPLETELY cleaned up and gone. You couldn't even tell they had been there, all debris was removed. Love the office staff as well. HIGHLY RECOMMEND THEM!

Cornerstone Exteriors installed a new roof for our entire house in Feb. 2015. Their work was done on-time and efficiently. Within one day the work was completed and our yard was clean. Their cost was competitive. Several other homes in our neighborhood recently had new roofs installed by Cornerstone Exteriors and their experiences were also first-rate.

I was amazed at how efficient they were in doing both the roof and siding. After comparing the amount of time it took other contractors to complete the work in our neighborhood, these guys were fast. They did an awesome job, which totally transformed our house. This saved me from selling and having to move. 
Jason made the initial visit. He was very professional, knowledgable and did not pressure us at all. The office staff was very responsive and helped out greatly when we needed to change the siding design because of a requirement from our homeowners association.
During the roof removal, they ended up causing some minor damage to the corner aluminum wrap of our neighbors house. When I pointed this out to Jason, there was no hesitation from him that they would fix it. They quickly took care of the damage. My neighbor did not even know that this happened. When I told them, he thought it looked better than before.
Clean up was done very well and they left the site looking like no one had been there.
They have dedicated crews that stayed and worked till dark in order to get the work completed in one day. That is dedication!
We are so happy with the quality of material and workmanship we received through Cornerstone Exteriors. 
All our neighbors and others walking by all commented how good the house now looks. We are still excited when we drive up and see the transformation of the house.

Simply fantastic work and top notch customer service on our Siding Work. No matter who you deal with from Roxanne, Kimberly, Mike, etc. they are courteous and professional. Highly recommend and will definitely use again on our next project. A+

The crew did an excellent job despite the bitter cold of this long winter.

I've used Cornerstone twice in the last year and will continue to use them for future window needs. Our house is older and we were unable to open the windows to get a good crossbrezze. So we called corner stone to replace windows and they offered a great window at a fair price. We then needed to have a new window for the nursery and we used Cornerstone again. Again I was pleased with the work they provided. The only issues was some (thought to be) scratches on the sash if the window. It ended up being glue, but it took some time to schedule someone to get out here to look at the window. The man who came out to look at the window was so wonderful and was such a great help. I really appreciated his expertise and professionalism. Thanks Cornerstone, I'll continue to use you in the future.

We recently had Hardie Plank siding put on our house, new window capping, and gutters done by Cornerstone. Randy was the local rep who walked us through the entire process.  We are very pleased with the outcome of the product and installation. Randy and the local office were quick to respond when we had questions & very helpful throughout the project. Overall we had a really good experience & would recommend Cornerstone in the future and would use them again in the future.

Our house looks beautiful and our rep Mike was fantastic and immediately responsive to any and all of the MANY questions I had.
I have very high standards. Job took a little longer than expected, but I would prefer that the workers
take their time as opposed to a rushed job. Also found a lot of nails on the ground after the job was completed, but overall well done. I would recommend them to family & friends.

From the estimate thru to completion, everything went perfectly. We had a last minute family visit to schedule around, and needed to schedule a rush, and they even helped with that and did an excellent job within the timeframe needed. Randy Chi and his crew were great, and all office staff and workers performing their job did well. We would definitely use them again for other work in the future.

Very well, the work was performed to our expectations and the workers were polite and courteous. We were very satisfied and would use them again in the future.

Cornerstone Exteriors recently completed replacement of my house and garage roofing. They also replaced my aluminum siding with vinyl siding.
I am completely satisfied with the professional and quality workmanship.
Other than a small communication glitch (later resolved) I was especially pleased with my sales contact, Reed Nitsche. He was always available to answer any questions that arose prior to, and during the work process.
I recommend this company.

I noticed Cornerstone Exteriors had an audit dispute on Angie's List.  I've emailed Angie's List about this.  So far no actions have been taken.  Cornerstone Exteriors does not have a licensing issue.  Please remove the disclaimer and warning.

95% of job was done immediately. Odds and ends still not complete two months later.

Once Cornerstone was approved to do the work their time line for starting and finishing was excellent.  I would highly recommend their service who is seeking what they can offer.  The replacement and repair was excellent. 

Excellent job. Prompt, excellent personal service, worked well with us and with our insurance comapny. Good clean-up job when completed.

Cornerstone walked with us from initial inspection for hail damage last March, multiple inspections from the insurance company, and finally installed new siding, a new roof and new gutters. They were very patient and allowed time for payments based on what the insurance company allowed. Wonderful workmanship! Great people to work with every step of the way. Rene who guided out project was fabulous and Grace in the office was always cheerful and helpful. Great company that does high quality work and are honest all the way through.-

Cornerstone was going door to door in our neighborhood and talking to homeowners who would be interested in getting new siding. They said we had hail damage and could qualify for it to be covered under our homeowners insurance. We decided to move forward and see what happened. It worked out great. Cornerstone worked with the insurance company to set up an inspection.   We were notified that we did qualify for an insurance loss. Randy Chi was great to work with.  He was professional and answered all of our questions.  He was able to work around our schedules which we really appreciated.  

Shortly after we worked out the details witht he insurance compnay, we scheduled a time for the work to begin.  The actual work was done very well.  The team that installed the siding was professional and kind.   They cleaned up their work everyday and made sure we were happy.  We were concerned about one small area on the siding and Cornerstone sent someone out to fix it up to our standards.  

We would be glad to work with Randy and the Cornerstone team again. 

Randy came to the house and inspected for hail damage.  He then met with our insurance agent and informed us that we qualified to have our siding replaced.  We decided to upgrade to harde board.  He was very professional and the process was going nicely until the building inspector showed up.  We live in unincorporated Wheaton and Cornerstone did not know that they needed a permit to do the work on our home.  Normally, the village does not require that, but since we are under Dupage Country jurisdiction, we were an exception to the rule.  The inspector told them to take off a bunch of the siding so that he could inspect their job.  We worried that Cornerstone would try to put the damaged boards back on our home because they were vague in the way they communicated a solution to this problem.  That was very stressful.  In the end, they had ordered enough  siding that they did not need to order more and the job was completed to our satisfaction.  I am very pleased with the way our home looks and with the harde board. 

Dear friends at Cornerstone Exteriors,

The purpose of this review is to express our gratitude in replacing our roof and siding this fall. Aside from loving the aesthetics and beauty that was added to our home, we would like to compliment your caring and professionalism on this project. From the beginning everything was done in a clear and concise manner much of which was created by Randy Chi, the exterior specialist. His knowledge of the work involved, the materials available, and financial aspect helped us go ahead with the work. I wasn't worried at all, and he was very straight forward. The crews who did the work were prompt, courteous, and efficient. We were concerned about the cleaning up aspect after such a extensive job, however we are very pleased as we have not found a stray nail or screw once they cleaned up. We wouldn't want anyone or any animal stepping on something sharp. The siding obviously was more involved and took more time, however the manager gave us updates on if they were running late or if they couldn't come that day. He had very good communication with us so we weren't left wondering where they were at. I had already told two of my neighbors of how much we were pleased. Please feel free to share this information with other customers. They made an otherwise overwhelming project easy.

They contacted us because they were doing similar work in the area. They worked with our insurance company, brought samples to us and made sure we were happy with our choices. They scheduled a date to have the work done and finished on schedule. The owner followed up to make sure we were happy with the job. What more could you ask?
