"We decided to close in an open game room upstairs. We had several contractors come over to provide numbers and scope for the project. As someone who is in the design/build industry you expect a certain level of service and knowledge. All the contractors minum Alter spent a grand total of 20 minutes looking at the project. Alter spent an hour looking at the project and going over various options and plans. Alter took measurements, pictures, videos of the area to remodel. While also presenting pictures and videos of previous projects. We are a firm believer in you get what you pay for. Alter's proposal for the project was 10 pages compared to the 1 page proposals from other contractors. Alter laid out the entire project scope, what is covered, what is excluded and expectations. During the project, Alter was at our house multiple times a day checking on the progress. What they said would get done for the day was done that day. The craftmanship was impeccable, and clean. We are forever grateful for Alter treating our home like their home. With the great work they did, we decided to excel another project to roll right after the first remodel. We wanted the master closet redesigned and they made it happen. As picky and precise we are as customers, there was nothing we noticed that had to be redone. Lines were clean and straight. They made both project match our dreams and desires. I will never venture out to hire someone else to work on our home. Only Alter will be the contractor to work on our home and feel like family."

"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!"

"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."

They were actually able to finish this project a lot quicker than expected.

I have dealt with some pretty sketchy construction companies and contractors in the past grateful that this wasnâ t the case here!"

"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 got the redesign plans, but I could not get them to re-engage with e to start work. They just went dark, after several followups. Weird because I liked their designs and probably would have given them quite a bit of business."

"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.
