"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!"

"We needed an old garage demolished and a new one built. Central Iowa Contractor Services handled everything including the demo, concrete work, electrical, roofing, gutters, and even new retaining walls on two sides. Everything looks great! Hoss is very easy to communicate with and the work teams were all professional and polite. Will definitely use this contractor again."

"Great. Neil's crew did a fantastic job. They worked quickly and you could tell they were confident in their work. We had used DeWit Construction several years ago at another home (this was before the roofing section became it's own entity) to put on a new roof after damaged during high wind/hail storm and also to rebuild the underside of an upper deck which had not been correctly supported. We are already considering them for another project."

"Very well. They are true professionals. John and Nathan know what they are doing. Always polite and clean up daily. We had a hole in the wall on the bedroom side and John came after hours, on his way home from another job, just to do the hole. I was then able to paint that wall before we had carpet laid. Very accomidating to our needs. They worked us into their busy schedule which allowed us time to perform some of the work ourselves. They were able to finish the work a week ahead of schedule. We are truly satisfified and have had many compliments on the improvements."

"Dave came right away and worked on getting an estimate for us. Unfortunately our insurance company fought us at every turn but Dave didnt give up he went to bat for our family to get what repairs approved that he felt needed done and what was best for our family. When they finally agreed his team went right to work. He has always been available when I had questions and has went above and beyond on numerous things in regards to repairs to our house no matter the extra costs. This company is here to make sure you the customer is happy at all costs."

"Des Moines Area Roofing was professional, trustworthy, and demonstrated excellent attention to detail from initial contact to job completion. Cleanup was so thorough that the next day you wouldn't even know that such a major project had taken place. It has been 2 weeks since the new roofs and we haven't seen even one stray nail left behind (and they did a complete tear down to both buildings, right down to the wood). An excellent company with which to do business. I offer my highest possible recommendation."

"The first company that was assigned by Choice Home Warranty did not show show or call for the scheduled appointment. I was told to contact the company, but I was not satisfied with the response and the new appointment. After complaining to Choice Home Warranty, they paired me with another company (HT Handy Works LLC). My plumbing issue was not covered under the warranty, but the company was able to resolve my problem, although it was costly."

Home Building FAQs, answered by experts

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

Shipping container homes last at least 25 years on average, but they can last even longer with proper maintenance. Since shipping containers are made from metal, they’re quite vulnerable to rust and corrosion. This issue is exacerbated in coastal areas or areas with a lot of precipitation. To extend the life span of your container home, install siding that protects the exterior. 

Yes, modular homes offer a wide range of customization options for layout, finishes, and features.

Yes, you can finance new construction, though the process often requires a different type of loan than one for an existing property. There are several financing options available:

  • Construction-to-Permanent Loan: This is a common option where a single loan covers the building costs and then converts into a traditional mortgage once construction is complete and you move in.

  • Construction Loan (Stand-Alone): This type of loan provides funding only for the duration of the construction project. Once the house is built, you will need to pay the loan in full, typically by securing a separate, standard mortgage.

  • Builder Financing: Some custom homebuilders offer their own financing options, which may only require a down payment to begin the building process.

  • Bridge Loan: This can be a useful short-term loan to fund your new construction while you are in the process of selling your old home.

  • Home Equity Options: If you are building a second home, you might be able to use a home equity line of credit (HELOC) or a cash-out refinance on your current property.

It's also important to be aware that some lenders may have restrictions on financing for DIY house builds, so be sure to verify that you can secure financing before starting your project.

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.
