Dear Todd, Just want to let you know how much we appreciated working with you and your team on finishing our lower level. From start to finish, we were never disappointed. Because of the foundation you set, we always had confidence and trust in the contractors coming through our door. Daryl and Matt were exceptional and a pleasure to have in our home! We absolutely LOVE the end result and are so glad we found Sparling! Thank you! All the best,

Sparling Construction did some remodeling in our basement and transformed part of an existing patio into a sunroom that gave us much needed extra room. Their workers were always professional, courteous and neat. Our 1-year-old great-granddaughter called them ‘the boys’.

We were pleased with the way Sparling Construction addressed our questions and concerns and the quality of their workmanship. We love our 4-Seasons Sunroom! Every morning starts in the Sunroom with a cup of coffee and the newspaper. One evening, through our glass roof, we watched a Bald Eagle soar. It can’t get much better than that!

We spend a great deal of time in our Four Seasons Sunroom and absolutely love it! If we were to move, we would most certainly have Sparling Construction add on one of their Four Season Sunrooms again!

Thank you so much to the staff of Sparling Construction and for the integrity you showed us throughout the construction period, which made the journey go real smooth from start to finish. The amount of space it has given us off our kitchen for entertaining makes it really enjoyable for having guests over. Now guests that come to visit try to figure out where they could incorporate a 4-Seasons Sunroom into their home!

Additions FAQs

What types of home additions do you build?

We build all types of additions, including extra bedrooms, bathrooms, kitchen expansions, family rooms, garages, and second-story additions. We also build stick-framed sunrooms—a more durable and comfortable alternative to full-glass sunrooms, especially for North Dakota’s climate. Every project is customized to fit your needs and lifestyle.

How long does a home addition project take?

The timeline depends on the size and complexity of the addition. Most smaller or straightforward additions typically take around 8–12 weeks. Larger or more complex projects—such as multi-room expansions or second-story additions—can take 6–8 months or longer, depending on the full scope of work. After reviewing your project, we’ll provide a clear and realistic schedule so you know exactly what to expect before we begin.

Do home additions add value to my property?

Yes. Adding square footage to your home increases its resale value and functionality. Additions like extra bathrooms, bedrooms, and expanded kitchens are especially appealing to potential buyers.

Do I need permits for a home addition?

Most home additions require permits, but you don’t need to worry about that—we handle all the necessary permits, inspections, and approvals to ensure your project meets local building codes.
