We used L.J. Neal & Sons to replace the windows on the front of our house 5 years ago. They were great to work with and we were so pleased with the quality of the windows that we just had them replace our sliding glass door and additional windows on the back of our house. Leo and Bridgette were very knowledgeable with helping us choose the new windows, since we were making some changes in style from our original ones. The new windows look great and the quality is a huge improvement from the builder grade windows we originally had. Leo even came out on the day of installation to check on the progress

We hired LJ Neal and Sons to replace all of our windows including the basement sliders and egress. The the windows are highly efficient, good quality, and look great. They also have great follow up service. A piece of window guide became cracked so I reached out to Leo and sent him a picture. They ordered the replacement part and Leo came out to replace it himself.
I recommend this company for window replacement.

One of our recently installed windows was difficult to lock. I wrote to LJ Neal and within a few days a serviceman was over and adjusted the window and lock fixed it in less than half an hour. The quick response and service was greatly appreciated.

Leo and team were responsive, professional and easy to work with. No pressure sales approach. The installers were prompt, considerate, and cleaned up thoroughly after completion. Leo came the day of the install to oversee the work. New windows look great!

All I can say is if you're looking for a window replacement company I would greatly suggest LJ Neal and Son. We purchased our brand new townhome in 2008, mind you I stated brand new. Every winter got worst and worst. In 2013 we had our first child on our way - We needed to do something! the baby's room was the coldest room in the house.... Every year we would go to Menards and put on the clear window film to get some type of protection. But with baby on the way. we were not going to do this ever again. So open up google search and search for window replacement near me..... You will get

I can't figure out how this company attracts new customers (if they do). I tried to do business with Leo Neal a year ago, but was put off by his unwillingness to come to our house, look at the bow window we wanted to replace, and provide a proposal - like nearly every other window company does. Leo's response was they would "be happy to review everything with when you are ready to move forward and sign the contrast and place your order." So, he won't come out to show the product, talk about specifications or discuss the project unless we commit to signing a contract, sight

This company did my siding on my house.
EVERY time it storms pieces of the siding falls off. I have tried contacting them over the years to come out and repair their work. Today I had a very respected restoration company come out and throughly inspect my siding. Their report was not the news I wanted to hear, but I was not surprised..... my siding looks 'wavy' and pieces are loose. Today I was informed that the siding was NOT installed properly, CANNOT be rehung because the siding was improperly cut AND damaged while being installed. I have fought with this company for YEARS to fix my

I agree with Michael E! This man is vindictive and mean.
My mother called LJ this afternoon to schedule an appointment to get an estimate. She spoke to him on the phone less than 5 min and made an appointment. A few hours later she decided to stick with the first company she called. She then emailed Leo Neal Jr. to let him know she wanted to cancel the appointment.
He responded via email with this DIRECT QUOTE:
