"TRS Builders was totally professional from start to finish. The work was completed faster than expected and the crew was extremely knowledgeable and worked in sync like a hive of bees (I know from my beekeeping experience) and left no trace of any work done. The value for the cost was exceptional. I would highly recommend TRS Builders for your next project!"

"Amazing job. The workmanship so good to match the existing wall and blend so it’s not a noticeable repair. Many neighbors have stopped by and commented on the good job. We were impressed with this contractor’s excellent communication. I would hire them again for any work we need done here at our home."

"Great contractor to work with since Dan will listen to what you are trying to accomplish. Understood the we were willing to take on some of work (I.e. demo) and purchase a majority supplies needed. Tile, grout, fixtures, tile boards, etc. This way we had control of some of the expenses. Plumber and tilers were very easy to work with since most of the dirty work was already done. Making it easier to finish their work quickly."

"As many of you know--finding a reputable home improvement company can be quite a challenge. We had some major projects to do in our yard and initially reached out to multiple companies requesting bids on building a 40 x 10 foot pergola, repairing a cedar fence and staining another major structure in our yard. Our experience in contacting home improvement companies was so disappointing. Inaccurate bids, no shows, and people showing up that presented themselves as home improvement companies but didn’t know what the heck they were doing. The only company that took the time to provide frequent consultation, accurate estimates, multiple visits to our property and consistent follow-up was Twin City Handyman! The entire staff was attentive to our needs and the projects were well done and completed on time. A big shout out to Darren, Kathy, Cory and Johnny and other staff members who assisted in completing our projects for their expertise and attention to detail. We highly recommend this company for all of your home improvement needs. Now, other members of our family are using TCH for their projects as well! Thanks TCH for a job well done. It was a pleasure working with you."

"The biggest standout to me with PK Salt is their integrity. They show up when they say they will, and they communicate clearly along the way. Building at your home can be so stressful. so when people show up when they are supposed to and do the job you are paying them to do it goes a long way towards building trust that things will get done right. I appreciated frequent communication and a company that stands by their work and their word."

"Reetz Construction did a great job! My new deck looks amazing! From start to finish, Ethan Reetz was fair, honest, respectful, and fast. He obtained the permit and finished our 15x15 deck in 5 days. We couldn't be happier! This young man is the best around to do a deck or job for you!"

FAQs for addition to existing structure building service projects in Cottage Grove, MN

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.
