"Let me say, there are fencing companies, and then, there is Garden Structures & More.  You really cannot even begin to compare the two.  Hal is a top-notch craftsman from start to finish.  This was not a typical fencing job, where sections are brought in, posts are set into the ground and the sections attached to the posts.  This was an entirely different experience.  The fence was built on site, board by board.  The vertical boards in the lattice actually go all the way down to the bottom of the fence. Of course, doing it that way requires a bit of a mathematical genius, when you are dealing with different width boards in between the lattice boards-- especially when you get into the corners where sections need to be a different width from the standard size. I also realized how much care was taken in dealing with the slight level differences in my yard. Hal was careful to make adjustments when possible, so that the top line of the fence remained level, even though the ground did not.  It is sturdier than any fence I've ever seen, and the attention to detail is wonderful.  Every side of each board is routered to give it a softer edge.  The posts don't need a cap.  The tops are routered the same as the rest of the fence, and they look simple and clean, a lovely complement to the clean lines of the fence as a whole.  The double gate with arbor is really beautiful.  I'm not a fan of black hardware, and Hal supplied some beautiful stainless that looks so much nicer.  Hal started right on schedule, and ended exactly when he said he would.  And, he is very thoughtful.  Not only did he build me a beautiful fence, but he put up a bird feeder that I hadn't gotten around to doing myself, and even brought my garbage cans into the garage on garbage day!  In the days since the fence was completed, I have received many compliments on the fence and arbors from people walking by.  And, they have also commented on what a nice crew installed my fence-- that it seemed like a great group of guys.  I would use Garden Structures and More again, in a heartbeat.  It was a great experience!

"We had a very large, rotting deck that needed replacing as well as siding with holes in it. We got proposals from 3 deck specialists. It came down to two companies, both Angie's List recommended. We chose Amy and Marshall because Amy came to our house with samples which got us excited about our new deck. In addition, Amy was notably proud of their previous jobs; their quoted price was competitive; their warranty for labor is exceptional; and responsiveness was great. Their crew was wonderful to work with. We are pleased with the outcome which included a couple of unexpected pluses and recommend them for future work."

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