What makes Parry Construction different from other builders in Boise?
We stand out because we focus on quality and personal service. While many general contractors hire other people to do the work, our team does everything ourselves. From working with the designer to building it, we pay close attention to every detail and make sure the work is top-notch.
We also use the latest ways to build homes that save energy, so your home is up to date and built to last.
How long does a home addition take?
Most projects take 2–4 months depending on size and complexity. We’ll give you a clear timeline up front so you know what to expect.
Do I need permits for an addition?
Yes. In most cases, permits are required. Don’t worry—we’ll handle the entire permitting process so you don’t have to navigate city hall.
Can you match my existing home style?
Absolutely. Whether it’s siding, roofing, or interior finishes, we match materials so your addition blends seamlessly with your original home.
What Idaho areas do you serve?
We proudly serve Nampa, Caldwell, and the surrounding Treasure Valley area. Not sure if you’re in our service zone? Just ask—we’re local and flexible.

I gave Dennis my vision of what I wanted and he brought it to life for me! They were very easy to work with! Thank you!!
Dennis was always informing us of what was going on and what steps were coming next. He went above and beyond. We wanted to convert our garage into a room and they set us up by insulating and priming the walls. When we are ready for our addition we will be coming back to Parry Construction.

They worked hard to stay in our budget as the prices of materials soared. Our home was completed in a timely manner and they got us in our new house before expected. We would highly recommend them to anyone looking at building a home or working on a remodel.

I believe Delbert has two qualities that are essential (and exceedingly rare) in a builder. #1 He knows how to build things - he went to college and studied construction. #2 He is honest. Parry Construction may not be the lowest bidder, but my experience indicates you will get what you paid for. We got a really well thought out, well built basement. I would work with him again anytime.

Delbert and Dennis are such a pleasure to work with, easy to communicate and really know their stuff. Not to mention they have been building houses in the Treasure Valley for over thirty years through the market highs and lows and have NEVER gone out of business. Plus they have one of the lowest contractor registration numbers in the valley. I highly recommend.

Had an excellent working relationship. Work was completed as discussed and problems were address quickly. Subcontractors were hardworking and easy to work with. Our addition was well-built and we plan to use them for a future project as well. Thank you!

They are truly professionals. From start to finish it was great to watch the progress. I am extremely pleased with the result of my remodel. They helped bring my 1965 constructed house into the modern times. Ron, was fantastic to work for A+. He was so helpful and was able to change things if needed with no problems.
