"Ely and team did a great job on demolition of my old patio and deck and the building of a concrete stamped patio. Not everything went to plan but Ely worked to solve any problem that did arise. His team was professional, efficient, prompt, and kept the worksite clean. Ely over communicated to make sure we were happy. The project was on time and on budget. As someone who has previously worked with poor contractors on home projects, Ely and team were a pleasant surprise. I highly recommend Ely and CQS for any project!"

"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."

"Went great, came inside with a great attitude. Had all the necessary tools and even had a vacuum when the granite needed to be cut to prevent a mess. He cleaned as he kept working in between. The sink looks beautiful and he double checked for leaks and paid attention to detail. I highly recommend him any home jobs and I am definitely giving him another call with another project."

"We hired AGC to add a closet and primary bathroom to our 1960s house, as well as completing some minor cosmetic renovations to the existing spaces. Their pricing was very fair, and communication was great from beginning to end! We never had to wait long for a response if we had a question or problem, and every AGC employee we dealt with was professional, courteous, and respectful. Our addition turned out beautifully, and we absolutely love our new and improved spaces. I'm so glad we chose them to handle the remodel of our forever home!"

"I recently hired LFM Remodeling to update the small master bathroom in my condo, and I’m so glad I did! They replaced an oversized tub and completely transformed the space into something clean, modern, and spa-like. Stav and his team were professional, responsive, and respectful of my home. They kept things tidy, finished on time, stayed within budget, and handled a few small hiccups without missing a beat. The tilework is beautiful, the fixtures look amazing, and the whole space feels calm and refreshed. I highly recommend LFM Remodeling — I’d definitely hire them again!"

"I hired Terry to build a 14'x20' lean to box building with no windows on an existing concrete slab. The slab wasn't checked for level and the building went up without addressing the issue. The slab issue was my fault, but I think a professional should check before building on anything. If someone is concerned for their product I think that person should say I can't build on that because it has an issue. I also understand time is money and once he started i was locked in. I am writing this to help the next guy. A slab check would have taken a minute and this is why it was so grievious to me."

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