Expert Room Additions in Westmont, IL

Room additions give Westmont homeowners a direct way to gain living space without leaving an established neighborhood. Most homes in Westmont were built between the 1940s and the 1980s, and many carry practical floor plans that no longer fit how families live today. A well-planned addition changes that. At Pro One Builders Group, Bogdan and his team manage the full scope of a room addition project, from initial design through final construction. We build bedroom additions, home office additions, family room expansions, and primary suite additions. Because Westmont's housing stock is largely mature and built-out, each addition is designed to tie into the existing structure cleanly, matching rooflines, exterior materials, and interior flow. We serve homeowners across Westmont, Hinsdale, Downers Grove, Burr Ridge, Darien, La Grange, Clarendon Hills, Western Springs, Willowbrook, Indian Head Park, Willow Springs, and Elmhurst. If your home no longer fits your household, contact Pro One Builders Group to talk through your options.

FAQ

Room Additions FAQ

Common questions about room additions in Westmont, IL.

Can you add a room to an older home in Westmont?

Yes, we build additions on older Westmont homes regularly. Most of the housing stock in Westmont dates to the mid-twentieth century, and our team is experienced working with those existing structures.

What types of room additions does Pro One Builders Group build?

We build bedroom additions, home office additions, family room expansions, and primary suite additions. Homeowners across Westmont, Hinsdale, and Downers Grove have used these addition types to solve space problems without relocating.

Will the addition match the look of my current home?

Yes, we design each addition to tie into your existing roofline, exterior siding, and interior layout. A cohesive result matters especially in established Westmont neighborhoods where home character is part of the street's appeal.

Is a room addition a good investment for a Westmont property?

Adding functional square footage to a Westmont home can strengthen its position in the local market. Westmont is a built-out village, so buyers who want more space often have limited move-up options nearby.

Do you serve areas near Westmont, like Burr Ridge or La Grange?

Yes, Pro One Builders Group serves homeowners in Burr Ridge, La Grange, Clarendon Hills, Western Springs, and several other communities across the area. Contact us to confirm service for your specific address.

ProOne made the renovation process feel simple. Everyone was easy to work with and very respectful. We love our updated space! I highly recommend using ProOne!

Had a great experience using Pro One Builders. We had a complicated job wrapping the exterior brick around our windows. Teresa and her team did a great job of taking their time to make sure everything was done properly the first time. I would like to give a special shoutout to Stephan. His expertise and creativity really helped get the job done the right way after a few initial complications with the original plan. Highly recommend using Pro One Builders for your next project.

Pro One is an excellent contractor. From their salesperson, Bill, to their workmen I found them professional and accommodating in every way. Special shoutouts to Daria, their decorator, who walked me through every step of the way and truly brought my vision to life and to Stefan, in charge of crews. Responsive to my every request. Superior workmanship.

I hired Pro One for some touch ups and updates to my newly purchased home. They were prompt and fair in providing and estimate and I’m very happy with the quality of their work. Once started, they were efficient in the work throughout the home. They also made sure to give clear communication on any updates to the work they’d do and the price update. Would gladly use them again.

We've used Pro One Builders for multiple (5+) projects at our house in the western suburbs of Chicagoland. Those projects include finishing our full basement, deck cleaning and painting, concrete step removal in our garage and near our front door, professional painting in multiple levels of our house including using scaffodling for high entry way, full kitchen/powder room/butlers pantry remodel, and hardwood floors throughout our main level along with wall removals. Along each step of the way for these projects, Pro One has been a pleasure to work with. We continue to come back to them for projects at our house due to their ease to work with and high quality of finished work they provide. We couldn't be happier with what they've helped transform our house into over the years and highly recommend them to any friends and neighbors that ask us about the beautiful home improvement projects that we've completed at our house. 10/10 would recommend.

Professional, courteous and dependable.

Bogdan and his team at ProOne have done multiple luxury jobs at my house. His teams fit and finish is of master tradesmen. I strongly recommend him.

★★★★★ I highly recommend Pro One Builders! They are an amazing, reliable, and professional team with exceptional knowledge and workmanship. They can handle just about any home improvement project, from hardwood floors and kitchen upgrades to bathroom remodeling, electrical work, repairs, and so much more. Their team is hardworking, trustworthy, and truly takes pride in doing the job right. It is wonderful to have a company you can count on for all your home remodeling and improvement needs. I would highly recommend them to anyone!

We were very happy with the work and team of Pro One Builder. We had 2 small bathroom completely redone. The team worked fast and cleanly. Very professional and respectful of timing. Highly recommend!

The remodeling of our bathroom was seamlessly done and the Handyman services provided by Pro One keep our household in excellent condition. Staff is always responsive, efficient and exacting. Cannot recommend highly enough
