"⭐️⭐️⭐️⭐️⭐️ Absolutely Stunning Refinish – Highly Recommend! I couldn't be happier with the way our hardwood floors turned out! We had some old, torn-up floors that honestly looked like they were beyond saving—but the transformation is unbelievable. After the refinishing, they look like brand new floors, absolutely gorgeous, with a smooth, rich finish that completely elevates the look of our home. Not only was the quality of the work exceptional, but the price was also more than fair—especially considering the results. On top of that, they were incredibly professional: they showed up 15 minutes early, ready to work, and clearly take pride in what they do. It’s rare to find that kind of reliability and craftsmanship these days. If you're thinking about getting your hardwood floors redone, do it—and call these folks. I can't recommend them enough!"

FAQs for addition to existing structure building service projects in Watertown, WI

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.
