Great Northern Home Exteriors Garden Doors

Add Style and Functionality to Your Home with Beautiful Garden and French Doors

Garden doors and French doors are both popular options for adding style and functionality to a home.

Garden doors, also known as patio doors, are hinged doors that open to the outside and often have a large glass panel to allow for an unobstructed view of the outdoors.

These doors are a great choice for homes with a backyard or patio, as they allow for easy access to outdoor living spaces.

French doors, on the other hand, are typically made up of two hinged doors that open in the middle and are often used as entry doors or to separate interior spaces.

French doors have a classic, elegant appearance and can add a touch of sophistication to any home.

One key difference between garden doors and French doors is their primary function.

Garden doors are often used to provide access to outdoor spaces, while French doors are more commonly used as entry doors or to separate interior spaces.

French doors also tend to have more decorative elements, such as ornate hardware and trim, while garden doors are more streamlined and practical in design.

Regardless of which type of door you choose, both garden and French doors can add value and charm to your home.

Great Northern Home Exteriors Patio Doors

Enhance Your Home's Aesthetics and Functionality with Sliding Patio Doors

Sliding patio doors, also known as sliding glass doors, are a popular choice for homeowners looking to bring in more natural light and create a seamless transition between the indoors and outdoors.

These doors feature large glass panels that slide along a track, allowing you to open up a whole wall and bring the outside in.

Sliding patio doors are a great option for homes with limited space, as they don’t require the swing space needed for traditional hinged doors.

In addition to their practicality, sliding patio doors also offer a number of aesthetic benefits.

They can create a modern, minimalist look and help to visually expand a space by giving the illusion of more square footage.

Sliding patio doors can be customized to fit the specific needs and style of your home.

They are also energy efficient, with options such as double-paned glass and low-E coatings to help regulate the temperature in your home and reduce energy costs.

Andrew Penn

I had GNHE install a door for me about a year and a half ago. We had massive water issues and also draft issues as this was a side entrance door. Since the installation, which by the way, was unbelievable and unprecedented, I was shocked at the meticulous matter as to which the installer took the additional time, and it has paid off as we have no more water logging issues and have zero drafts. The side entrance is Now a warm part of our house and has made a dramatic difference. I would highly recommend Great Northern, and I will be bringing them out again in the spring to replace our front door.

Kathy Wall

I don’t usually write reviews, but we are so impressed with our new windows! I had several quotes and decided to go with Great Northern Home Exteriors. It was a positive experience from the quote to the installation.
Everyone was informative, experienced and friendly. I will highly recommend this company – and already have!

Wendy H

We had 6 vinyl windows installed. On our very old brick house. The workmanship is excellent. It was done on time and clean up was perfect. The new windows look great and it was reasonably priced compared to other quotes we got. We will be getting more done by them and maybe a door as soon as we can. Thanks.

Dave Davidson

GNHE was very professional. I had nine windows replaced. The techs showed up on time and completed the work in the time frame that I required. I have no issues at all and have no problem recommending them for any of the services that they offer.

 

Kim Wark

This is the second time I have used Great Northern for a large project at my home. The first time was replacing all my windows, and the most recent project was replacing all the fascia, soffits, and eaves troughs. Clodette and her crew are efficient, great to work with, and continually provide quality work at a fantastic price! I will most definitely use them again for my next big project!

Ernie Jones

GNHE installed three bedroom windows in my home a few years ago, and I was very satisfied. I just contracted with them again for new front and rear doors. They are great to deal with, and their prices and workmanship are top-notch. I highly recommend this company.

Larry Wittenberg

I have dealt with Great Northern for many years and have found their workmanship and materials to be excellent, and the prices were competitive.
