"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."

"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!"

"My feeling in writing this review is deep and total ambivalence. During this entire project, there were moments of great satisfaction...and great frustration/anger. Let's start with what I felt was done extremely well: Jèsus - The real MVP of this project. This man absolutely deserves the utmost praise and respect for how great a job he did installing the tile for my kitchen/dining room floor as well as the backsplash near the end of the project. The pride he takes in his work shows and my friends/family were blown away at the pictures I showed them of what he did. If he's reading this, I'll recommend you to ANYBODY needing some tile work done! BAH Carpenter (name escapes me, my apologies) - That great frustration/anger I mentioned earlier? This man quelled some of it due to some incompetence on the part of the GC and crew chief (more on that later). Toluca Granite (countertops install) - I already gave them high praise on Yelp, but I'll echo those sentiments again on Angie's List. From the first contact, to the finished product, they were absolutely outstanding! With that being said... Let's talk about where they severely dropped the ball on this project: Drywall - The people they hired for my drywall work were HORRIBLE! They dirtied up my house without any consideration. Plaster footprints all over my bedroom floor, in my bathroom (they stepped ALL OVER my shower drying mat), dirt all in my tub, plaster chunks on my bedroom light switch, my towels, on the side of my sofa, and on the legs of my dining room table. Then, to top it off, they used my broom to SWEEP wet mud and plaster. Total lack of communication - THIS is why my grades in certain parts of this review is so low. Delays are a part of the game sometimes. I get that. But this was ridiculous. First off, there was a situation where my cabinets were delivered and supposed to be installed on 12/29. I came home early from work thinking I was going to see the crew installing the cabinets or already having them done. Didn't happen. Instead, I came home to a pile of cabinets all over my dining room floor and the pantry cabinet standing tall in my living room. So I'm thinking, perhaps they went to go get some more tools/materials and they'd be back. Didn't happen. I texted the crew chief asking what the status was on getting the cabinets installed. Didn't hear anything for nearly 2 hours and then when I did, received the equivalent of "we need to talk." Man is on the phone telling me that the cabinets (I spent a serious amount of money for) don't fit. You can only imagine my reaction to hearing that. It was a sh***y way to end the year and I wouldn't hear back from anyone until after the New Year holiday. Continuing, I get a text on 1/2 from the crew chief wanting to setup a meet with me, the GC, himself, and their carpenter on the cabinet situation. 1/3, the carpenter came through and stated that all but one of the cabinets CAN be installed after he laid out the scenarios for me. The one that couldn't? The GC screwed up on the order/measurement of the cabinet that was to be to the left of my stove so that one had to be reordered. Downtime? 2 weeks. The next instance is what pushed me over the edge: Countertops go in (they had to make two trips due to the delay in the aforementioned lower left cabinet) and I texted the crew chief for an update (1/22) and he tells me that ANOTHER cabinet was mis-measured and that the GC had to order a replacement. If I hadn't reached out, I wouldn't have known. I was ****** off beyond belief. I got so tired of "oh hey by the way..." finding out about these delays that I called the GC directly and voiced my displeasure of being kept in the dark about these screw ups. Downtime: approx. 12 days. Now, despite all of the venting, the delays, the mess ups leading to said delays, the results are amazing. The finished product I'm extremely happy with and it all came together beautifully in the end. It's everything leading up to it that wasn't as pleasant. Advice: tighten up on that communication. If something is wrong, let the customer know asap. If you're waiting for them to ask you what's the status update and THEN you tell them of what's wrong, it comes across as if you have something to hide. Too much money is being invested to keep people in the dark. Also, don't ever hire those drywall people. Ever. Again."

"We had some very detailed/complex requirements for building our outdoor living space that many people wouldn't even bid on the project. Terry not only came in at a great price, and great quality, but went above and beyond in problem solving. He came up solutions that not even my designers had thought off. We are very happy with the results. I'll be coming back to T5T for all my projects."

"We had the LET Group do a multifaceted remodel and construction effort on our home: remodeled the existing garage to a game room, added a bathroom, remodeled/moved the laundry room, remodeled the kitchen and main bathroom and built a new stand-alone garage with workshop. As other reviewers have noted, the LET Builder Project Manager, Luis Taipe, is fantastic. As all construction projects go, there were schedule problems and infrequent worker issues, but the key to a good project is how well these issues are managed and Luis is extremely professional and handled all issues efficiently and effectively. As other's have noted, Luis actually identified issues that my wife and I would have not noticed or ignored and had them corrected to his satisfaction first which was often more stringent than we would have requested. We struggled at the start of this project to find a good contractor and actually delayed the project several times because we were not comfortable with either the potential contractors or their proposals. This changed when we met Luis and listened to his absolute professional observations and recommendations during the initial project assessment and proposal process. His proposals were detailed and he was responsive to changes. Yes, there were several contract changes, but we were aware of them (no surprises) and were part of the process in developing the contract changes. This was a very big step for my wife and I and it was a major project ---- could not be more satisfied with the results and have already passed on recommendations to neighbors. Would recommend LET Builders to anyone with Luis as the Project Manager. Luis is personable, professional, and extremely responsive --- met his family as well and it is a very nice package to have worked with."

"Less than a year after we moved in, we discovered mold (to which we are sensitive) in our "new" kitchen. Patriot Construction knew exactly what to do (hint: it does NOT involve bleach or DIY air samples) to handle the situation safely and also whom to contact regarding the testing. In addition to having the proper equipment, they were really good at explaining the different options and what each one might cost. They also could have taken advantage of the situation and told us that we needed an entirely new kitchen, but instead,their in-house master carpenter was able to build the needed cabinets to match the existing. We highly recommend them and will use them again on future projects."
An idea of how you can turn a vaulted ceiling into a cool and useable space.
This used to be a dark and dirty attic. Conversions like this can be a great way to add square footage. With structural changes being one of our strengths, we can show you how to maximize your
space.
Lighting can transform any space into something magical.
Why be normal? Wall tile and a hexagonal stain glass window created an awesome mood for this homeowner.
Herringbone mosaic is very time consuming, but the results are worth it.

"Allan & the guys working at AC Cornerstone do quality work. They built my house in 2005. I know they build quality because I watched the attention to detail and selection of quality materials that last. In 16 years, I've had only minor/expected maintenance issues. Everything still works. No cracks in the rock. This house is solid and built to last decades. I love this house. Building anything can be stressful with 1000's of choices and unanticipated problems. Allan's friendly personality takes away the stress and he has the knowledge/experience to solve or work around any problem. Happy Long-term Customer"

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.
