5 Stars for Liberty Windows & Siding!!!!!

New Alside Mezzo Windows
D. Taylor   Glen Burnie, MD

As a new homeowner, embarking on such a huge home improvement project was nerve-wracking. I was unsure if I was making the right decision or costing myself more in the long run. I have an older home and new windows were a must. With this in mind, I heard Mr. Deily on Heaven 600 one morning and felt compelled to call. Mr. Deily, understanding my hesitation with purchasing new windows, came out not once, but twice to work with me on my new windows. He worked with me within my budget and ensured the job was done with the upmost excellence by coming in personally to complete the final piece (i.e., my bathroom window). Mr. Deily was also the link to a professional, warm crew. From Cathy, who was amazing with communication and scheduling and the installation team (Rob, Sean and George), I felt confident in my purchase and the team working on my home.
Liberty Windows and Siding truly are a blessing. Their entire team is dedicated to helping the buyer, any way possible.

I am proud to pen this letter in hopes that it will be added to your testimonial portfolio.  We were blessed to purchase a home which needed all of the windows replaced.  At our first meeting, you walked us through the window-buying process, made us aware of our options, and spent a lot of time making certain that we understood what to expect from start to finish.  From the outside as well as from the inside, there has been a tremendous positive change in the appearance of our entire home.  The friendly installation crew came in, worked professionally from start to finish, and the cleanup job was impeccable.

Needless to say, we are so proud to acknowledge that we used your company.  It was our pleasure afterwards to advertise Liberty Windows & Siding, Inc on our front lawn as the business who had done the work.  Please be fully assured that if ever there is another opportunity for us to purchase windows or to recommend a company that serves with integrity and communicates effectively with its customers, it will certainly be Liberty Windows & Siding, Inc. Again, thank you for the beauty that you have brought to our home which we can enjoy for years to come.

This letter is to say what a  wonderful job you all have done. You all have installed new windows, a beautiful front door with side panels and siding to my home a year or so ago. Since you all have completed such a wonderful job we decided to have you install a brand new roof.

The house looks wonderful, we have so many neighbors, family and friends asked who did the work. I will make sure I refer them to Libery Windows and Siding. I feel like I have the best looking house in the neighborhood.

New Alside Excalibur Windows & Entry Door w/ Transom
B. Short  Windsor Mill, MD

I just wanted to send you this letter to express how grateful I am about the (8) new windows and Front Entry Door that your company, Liberty Windows & Siding installed in my home in May 2013.   I purchased this house in August 2012, and had no idea as to the status of the windows in my new home; they looked good to me (first time home buyer). During the winter months I quickly found out that they were not good and air was coming through as if I had my windows and front door wide open.  I had met with two other window companies and they give me estimates, but I really was not feeling the gentlemen that came out.  I felt as If they were pressuring me to purchase their product that day, or I would miss out on this great deal.

I knew that this was a very large purchase for me and wanted to get the best company with good quality products at a reasonable price.  I have heard your commercials on Heaven 600 several times and heard you speak on that station about your products and services, but each time was unable to get your telephone number.

I finally was able to get your telephone number and scheduled an appointment with you.  The day you came to give me the estimate, was one of the windiest Saturdays ever and you asked me how I slept in the room because the wind was just beating through the cracks of all of the windows and the front door.  The windows and door was measured and shortly after, I received a call from your company with an installation date.  Dale and his crew came promptly at 8:00am and started work right away.  They had my (8) new windows and Front Entry Door installed in no time.  They were very good at their job and were very professional and even cleaned up behind themselves, which was an added plus.

They worked so hard, I felt guilty because they did not take a break, so I ordered them pizza for lunch so they can have something to eat.  I just wanted to let you know that I am really, really grateful and satisfied for the services rendered from you and your company.  You were very polite, attentive and did not give me that car salesmen pitch.  You presented your products, gave me a great deal with extra bonuses for being a Heaven 600 listener and your products are, so far, living up to everything you told me.  I have told all of my friends and family what a great job you and your company have done.  My mother can’t wait to come back and see the finished products.  I am also planning on having my roof and deck done through your company in the near future.

Terry & Clayton H.    Pikesville, MD

I am very pleased with the services rendered by Liberty Windows and Siding in the spring 2012. When my husband and I met with Peter Deily he was very thorough and professional in his consultation for replacement windows. He gave us an estimate that we couldn’t resist.   His work crew was the best.  They installed my windows the same day, cleaned up after themselves, and replaced some dry rotted wood at no extra cost. I highly recommend Liberty Windows and Siding for all of your future home improvements.

Lakia N.    Randallstown, MD

I just want to thank you and your company for doing such an awesome job on my new roof installation.  The crew arrived on time and was finished in a timely manner.  They surprised me by how quickly yet efficiently they finished the job.  They even noticed my chimney needed a side covering and provided me with one.  The crew was very professional and cleaned up when the job was completed.  This is the second project that I had your company complete for me.   Back in the fall of 2011, you completed a window and sliding glass door installation for me.  The crew did such a wonderful job; I knew I had to use them again for the roof installation.  My father recently had a roof installation as well.  I told him, if you want quality work at a great cost, go with Liberty Windows and Siding!   I appreciate all the work that you have done for me and look forward to using you for future projects.

I listen to the Heaven 600 program all the time, especially the Elder Lee Michaels program, but this particular morning when I heard the Liberty Windows & Siding commercial I really paid attention to it, and decided to call for an appointment.  After checking with several other companies, I decided to have my home upgraded with windows from Liberty Windows & Siding, Inc,  My windows were recently installed, and I am well pleased with the quality of the windows.  Peter Deily is professional, courteous and friendly,  he took the time to explain everything in full detail to me.  I was also impressed with the team of guys assigned to the task, they really worked well together, and they even cleaned up everything after the job was completed.  Thank you Elder Lee Michaels and the Heaven 600 family for providing good information on a reputable and dependable company, I would recommend this company to my friends and family.
