"Thank you for coming to see what the problem was. Our furnace was 15 year old and for the past few years we have had to spend a lot of money to fix it. It went out on the coldest days and I was scared my pips were going to bust. They were able to replace it right away. They also made sure to give me the pamphlet to register the Warranty. I’m very grateful and I recommend them to anyone that needs a new furnace. "

"The job was to demo, temporarily support and then reconstruct a two story wooden structure supporting a roof overhang on a split stair structure for an apartment complex. It was a tricky project. Not only did they complete the work on time and budget, they came up with 3 great ideas to solve some typical retro fit issues that come up with jobs like this. They also did a good job cleaning up after the job was complete. They really know exterior framing."

FAQs for addition to existing structure building service projects in Sandwich, 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.
