"Once he was able to fit us into his schedule, his crew showed up promptly and worked til the job was complete. Joe was patient and helpful in examining our options for insulation, doors and windows and his price was fair. I had a couple change orders, which he graciously fit in ... small sliding door to a loft. His crew worked like a well-oiled machine and did a great job on everything. Windows were placed exactly as we asked and the steel interior turned out great. Thank you Cover's Construction!"

"Our 100+ year old house had some very real structural problems (some of which couldnâ t be totally evaluated until some walls were opened up) but Scott was very honest when presenting what needed to be done. He was accurate on the timeline, and he and his crew showed up every day. Communication was good - we always knew at what stage the project was at, and anytime there was something unexpected that came up, we always knew about it. I felt that the pricing was more than fair and I would definitely use Essence Construction in the future."

"Mike and his crew did an excellent job on the basement remodel project. The project was to add 2 rooms, 3/4 Bath, laundry and storage closets in the basement. Prior to signing the contract, Mike spent a lot of time to understand the requirements and provided a number of suggestions as well. The quality of his work is excellent and he also ensures that the work done by sub contractors (plumbing, electrical etc) is of high standard as well. He pulled permits from the city and worked with the inspector to ensure that all work was according to city's building code. We are happy with the quality of his work would definitely recommend him for any home remodel project."

FAQs for shed, barn or playhouse building service projects in Knoxville, IA

Most sheds larger than six feet by eight feet require a foundation to remain level and dry. A compact tool shed might get by without one, but anything heavier should sit on at least a 4-inch-thick stone-and-gravel pad that extends two feet past the walls. The gravel protects wood skids and promotes drainage. If you want maximum stability—and your budget allows—a poured concrete slab is the strongest option.

Your ideal shed size hinges on purpose. A common 10-by-12-foot kit gives you 120 square feet—plenty for lawn tools and bikes. Need just a spot for a mower and a few rakes? A compact 4-by-7-foot model should work. If you’re envisioning a workshop or hobby room, look at 12-by-16 feet or larger.

A good rule is to raise the shed floor four to six inches above the surrounding soil. That clearance encourages water to drain away instead of pooling beneath the structure. The simple step is especially important for wood floors and skids, helping deter rot, mold, and insect damage while extending the life of your new outbuilding.

Choose the route that fits your goals. Prefab sheds arrive in standard layouts and go up fast—perfect for basic storage on a tight timeline. Custom builds cost more and take longer, but let you add windows, wiring, plumbing, and unique finishes. Balance budget, features, and timeframe before deciding which type of shed is best for your needs.
