Alter Construction offers estimates, proposals, design services, home improvement, remodeling services, home modifications, custom homes, general construction services in Austin, Texas and adjacent areas. We are a full service construction company. With years of experience we saw the lack of customer service and proper execution for new builds and remodeling projects. For that reason, our specialized team is dedicated to providing families with responsive, clear communication. We guarantee an outstanding customer service experience. Whether you need a kitchen remodel, a bathroom remodel, a room addition, or home modifications for elderly or disabled residents, Alter Construction will complete your project with responsive communication, to your satisfaction, and on time.

"My husband already left a review for our project, but I wanted to add some additional praise. Alter Construction did an absolutely wonderful job replacing our floors and I highly recommend them! Communication: One of the first things you'll notice with Eli and his team is the tremendous amount of communication. He'll talk you through everything, provide recommendations as necessary, and answer any questions. On top of that, Eli sent us multiple updates every day that we were out of the house to keep us aware of what was happening. Pictures, video, text explanations, and he was always available for a call. It really put my mind at ease that the house was well taken care of in our absence. He ran the outside taps when it froze, kept the house at the temperature we requested, and cleaned up everything after. He also made us aware of little things like how the paint color we picked for baseboards didn't match the existing trim. With everything he did, made sure that we would be happy with the finished product. Quality: The workmanship is outstanding. The tile is cut and laid beautifully, with no hollow sounds when walking. My father used to lay tile back in his day, so trust me when I say it was well inspected after! Our walls have rounded corners, so it was very nice of Alter Construction to cut and round the baseboards instead of leaving them sharp. It looks very clean now. Attention to Detail: What really makes the work stand out is the team's attention to detail. They replaced a section of baseboards that wasn't in the work area to make them match because they were visible from the living room. They were kind enough to reinstall our baby gates at a higher position because the new baseboards were taller than the old ones. They even patched a hole in the carpet of one of our bedrooms with the scraps they pulled up from the living room. This wasn't something that we had asked them to do, they just took the initiative to really make everything nice for us when we came home. Summary: If you're looking for someone to do work on your house, you can't go wrong with Alter Construction. They'll take care of you like family and I promise you won't be disappointed."

"I am so grateful for Terry and T5T Contracting. From the moment I met Terry, I knew he was the real deal—down-to-earth, honest, and extremely knowledgeable. His family has been in the business for years, and it’s clear he understands what homeowners need during a renovation. Terry is prompt and timely in his communications, and he showed incredible patience and kindness throughout the process. Living in a home during a renovation is not for the faint of heart, and inevitably, challenges come up. What stood out to me is how Terry always addressed concerns quickly and thoroughly, correcting any issues with professionalism and care. The subcontractors that T5T works with are also excellent. Every single person who came into my home arrived on time, was fully prepared, respectful of my home, and delivered truly outstanding work. That level of consistency gave me so much peace of mind during what could have been a stressful process. "

FAQs for addition to existing structure building service projects in Round Rock, TX

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.
