"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."

"Real Rating: 4.5 We used LFM to remodel our house, including our kitchen and main bathroom and closet. They also installed new floors, painted walls, removed popcorn ceilings, and updated the guest bathroom. We unexpectedly had to replace all of the wiring and insulation but those kinds of issues can be expected when you remodel a house built in the 70's. We worked with Arie and Justin. We used the WhatsUp app for communication, which was helpful. There were some challenges with communication; however, once those got resolved, things went smoothly. The crews worked hard and did beautiful work. Justin was awesome and brought some thoughtful touches to the project. We appreciated his support."

"I hired William initially to rehang a stuck back door for $150. Then I asked if he would trim a stuck wooden patio door, reattached some gutters and hang some thick plastic curtains on the outside of a patio. He did all these cheerfully, and along the way, selected about 25 vintage LPs I had as payment for the extras. I guess I should have figured on finding a music aficianado in Austin being a pretty good handyman!"

"I had a lot of issues with my house stemming from some major structural issues with the house. I spent quite a bit of money repairing the house but it left the house needing a lot of cosmetic work, and in the meantime, there were areas of the house that needed to be updated. I contacted AGC with a small budget and a very specific amount of time I needed the work done in and they walked us through step-by-step, were patient with the financing and got started exactly when they said they would. Additionally, Geoff advised me and helped me with issues that cropped up that weren't part of the scope of work. We were super happy with AGC and can't wait to use them again for our next project."

"I was very impressed with the work Shay and Makai did on our recent project. We worked together on the design, the final result was true to our vision, and they were very flexible with minor changes along the way. They were responsive and easy to work and the final result was excellent. "

"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.
