"Wade does 95% of the work himself. Bid was more than fair for our project and there were no cost overruns. I was very pleased with the quality of the work and so was the city building inspector. Wade handled changes to the project when we had to move a door and stairs to a different wall midway through the project. We've already hired him for another project."

"They did an amazing job and were super helpful! I love the deck work they did and how friendly they were to have around. Excellent work, great price for the work, and I would love to have them around again to work on some other projects in the future."

Brady is the best you'll ever find for home remodeling projects.
Showed up on time. Took the time to make ever job right.
Projects were worked on over a number of months, one at a time.


The best and most honest tradesmen I've ever found.
We moved to Texas in January of 2014.  We whish Brady could have come with us.
I've found some good (and bad) people to work on the Texas home.  But no one who comes close to the quality of work done by Brady Brower.

"The man I talked to was very professional and timely. However, he explained that this particular job was beyond the scope of what their company does. I would certainly use them on another 'issue'.

"When I asked for referrals for someone to put a culvert in on our property prior to our home being built I was immediately given Randy Fowlerâ s name. I fully understand why. His communication and persistence in finding the materials needed to get the job done in a very timely manner was impeccable. The job was incredibly well done. I would highly recommend Randy Fowler LLCâ ¼ï¸"

"I couldn’t be happier with my new deck! From start to finish, the team was professional, punctual, and detail-oriented. The workmanship is top-notch, and you can truly see the quality in every board and finish. They respected my home, kept the worksite clean, and completed everything within the timeline we discussed. This was a big investment for me (around $10k), and it was absolutely worth every penny. The deck is sturdy, beautiful, and built to last! I already know it’s going to bring a lot of joy and value to my home for years to come. I highly recommend them to anyone looking for quality, reliability, and outstanding craftsmanship."

"Once I sent her all the measurements, it took her a little while to get the options back to me.  Overall, they're good designs.  However, they're very simplistic and give general ideas for space planning.  I was hoping to have a better idea for sizes of furniture for the space and some variations on staging.  
Jill was very responsive when I did have a question.  I'm not sure how helpful it is to have a virtual design done.  If we lived in similar cities, I'd probably use her again for help with additional designs.

FAQs for addition to existing structure building service projects in Andover, IL

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
