Review №1


We recently had a replacement window installed in our home by Big L. From the start, every employee that we dealt with was extremely helpful, professional, and very knowledgeable. The suggestions offered were excellent and they worked with us to stay within our budget. The professionalism and craftsmanship of the 3 installers went way beyond our expectations. Our new window, with the interior and exterior trim is absolutely beautiful and has enhanced the look of our kitchen tremendously. I will continue to recommend Big L without any reservations. Thank you for an excellent job and this opportunity to be able to publicly endorse your company.

Big L converted 3 patio doors to windows in our living room and did a fantastic job. They were on time, finished a day early , were neat , respectful and their work was impeccable! I wouldn’t hesitate to recommend them.

Purchased doors will definitely improve the comfort level, as well as the curb appeal and interior aesthetics of our home. Quality company, Al H., sales rep., visited our home to discuss options and invited us to showroom to view manufacturers doors options. We chose ProVia doors. The doors installers, Derek and Shane, were very prompt, courteous, neat, and competent.A satisfied customer.

Big L put in a window yesterday, adding much light to a dark room. The wood work is beautiful and perfectly matched my other windows.

Big L was recommended by a family member as being outstanding. All employees were honest and efficient from the receptionist, to the sales representative, and the installers. Installers were clean, polite, and didn’t complain about installing doors in 20 degree weather. Their hard work and product are worth every penny.

Replaced a large picture window with 2 double hung windows. Installation techs were so professional. Left my home inside and out spotless. The work was very professional and the look exceptional. When im ready to replace the rest of my windows will definitely call Big L.

Big L carries a superior line of products when compared to big box stores. I recently found out of the door company Provia by reading an online forum, and come to find out Big L offers these doors. I have ordered windows through Big L and am looking forward to ordering a door. Their product lines offer very good warranties which make the purchasing decision that much easier. Big L does offer their own installation, but due to my project timeline and their booking schedule I opted to order the windows and doors and install them myself.If you are looking to install a product yourself it may interest you to shop around for the best price. When doing a supply order through Big L there seems to be considerable markup versus a wholesaler.
