The mission of Windows & Doors By Brownell is to sell windows and doors in a complete retail center which addresses all contractor and consumer needs from start to finish. Our team is committed to helping the customer make an educated buying decision. We will work continuously to improve the “one stop shop” philosophy by integrating services in a comfortable environment. We accept change as a basic premise and will adapt to market conditions to provide each individual customer with the best product at the best price. We believe quality assurance is based upon qualified personnel and excellent product.

Les Brownell started Windows & Doors By Brownell in April 1991 with the concept of specialization. The focus of the business was on residential exterior openings. He began the first year offering installation of Marvin Windows & Doors.

Over the years the company has remained committed to Marvin Windows and Doors, however, a few select product lines have been added to handle the customer’s entire exterior wall needs, including Velux roof windows, Therma-Tru entrance doors and Larson storm doors. Les believes quality manufacturers are a vital aspect of the business and remains dedicated to these manufacturers.

Our innovative Williston showroom was built in 1998 with the purpose of displaying product lines in various interior and exterior settings. The design of this showroom emphasizes how windows and doors look in real home settings and displays a wide variety of windows and doors in different sizes, shapes, colors and combinations. In 2010 Windows & Doors By Brownell expanded and opened another showroom location in West Lebanon, NH. We continuously expand and update our showrooms to include new product offerings.

The focus of Windows & Doors By Brownell has been the residential housing market with increased emphasis in the commercial area. We have expanded our installation services to include commercial projects. Over the years, the housing market has changed and we have seen consumer demands shift from new construction to remodeling and replacement. Consequently, we believe that an expert sales team with extensive building knowledge is essential in today’s marketplace. Educating the customer to make correct buying decisions for their unique project is the essence of our business. Service is critical to maintaining a competitive edge and Windows & Doors By Brownell has its own Service Department dedicated to insure product performance.

What began as a single man operation has grown into a dynamic company. Every employee works hard to ensure the customer engages in a positive experience!

Today, Windows & Doors By Brownell remains a family owned and operated business. Les continues as President/Owner and is very active in day-to-day operations – specifically in the Installed Sales portion of the business, Tomma is Vice President and Marcy is the Operations Manager.

At Windows & Doors By Brownell we are committed to Marvin. Why? Quality, aesthetics and superior performance. It’s simple, Marvin makes an excellent product.

Customer Testimonials

“I love my new window and the installer seems to have done an impeccable job. I’m so happy, thank you! Will definitely use you guys again as I continue to replace these windows!”
Jenny, Lyme, NH: July 2014
“We want to let you know that the windows installed this last summer by your crew are everything advertised and then some. There is a major difference so far in comfort within the first floor, and we anticipate that when the REALLY COLD stuff arrives it will be even better.”
David & June, December 2010
I’ve lived in my circa 1830’s home for the past 43 years and I’ve always known which way the wind was blowing – depending on which windows were rattling and where the drafts were coming in. During last night’s storm all was quiet in my house – no window rattling, no cold drafts, nothing! This new quiet is attributed to my recently installed Marvin Double Hung replacement windows. Thank you so much, I’m very pleased with my ‘quiet’ Marvin windows!
