"If you need a bathroom done, call someone else. We noticed water leaking outside the shower walls. We called. The first fix was them putting dry wall putty into a wet hole without finding the problem. My finger went right through the hole.They randomly half caulked one side of the shower wall panels.Days later, water continues to leak, and we lifted up the flooring to discover the flooring and subfloor had been soaked from the leaking shower. They come back. Cut out the drywall and caulk the entire shower that WAS NEVER CAULKED TO BEGIN WITH, we had to request they do this.Owner stated it wasn't mold, even though it wouldn't come off. Every time we had them come back, it looked worse. After they said they"fixed" everything, they did not replace the trim. Left paint on the floors, a screw from the new drywall is exposed after sanding and painting it and various pant chips. I've never seen a company rush to get a job done in all my life. We had to call them to come back and finish the initial job. We saved for years, YEARS FOR THIS REMODEL, and we SPENT THOUSANDS OF DOLLARS. Never again will I have a contractor come to my home."

I have been servicing, repairing and installing every aspect of a home and yard for as long as I can remember. I will work with every customer to meet their needs for their project. Pricing is always fair and negotiable. Since I have sold most everything we would need for your project, I can also help you get the materials at a great price.

FAQs for second story addition building service projects in Dekalb, IL

Converting a vaulted ceiling into a second floor requires three to six months from planning to completion. The process begins with several weeks of design and engineering, followed by permit applications, which vary in processing time by location. 

Construction itself spans several months, including framing, systems installation, and finishing work. Weather conditions, contractor availability, and inspection schedules can all influence your project timeline.

Several factors could make your conversion challenging or impossible. Inadequate roof support structures, insufficient foundation capacity, or problematic truss configurations might require prohibitively expensive modifications. 

Some homes lack the minimum ceiling height (12 feet at the lowest point) needed for functional second-floor spaces. Building code restrictions in your area might also limit conversion possibilities, particularly in historic districts or homes with specific architectural designations.

Begin with professional assessments from both an architect and a structural engineer who will evaluate your home's specific characteristics. They'll examine existing framing, measure available headroom, assess load-bearing capacity, and identify potential obstacles like HVAC ducts or plumbing vents. 

These experts will also review local building codes to determine feasibility. Their preliminary analysis provides crucial information about structural requirements and potential limitations before you commit to the project.

Whether you'll need temporary housing depends on several factors, including the project's scope and your tolerance for construction disruption. Major structural work creates significant noise, dust, and potential utility interruptions that many families find challenging to live with. Safety concerns may also arise during certain construction phases. 

Some homeowners successfully remain by isolating the construction zone and establishing clear work schedules. Discuss living arrangements with your contractor early in the planning process to make informed decisions.
