"Shawn and his guys do amazing work. From the first time I met him, I knew he was honest and professional in what he does. There was a problem with flooring issue during the job and he fixed it for me. Just today, I had an issue with my doors sticking and he came to fix it. He is a stand up guy for sure.

Norse Construction, LLC is a unique small business. Over my 30 plus years of construction I've had numerous customers tell me of contractors who don't show up, don't clean up after themselves, build what THEY want and NOT what the homeower wants. Its simple. I started Norse simply because you should have what YOU want and when you want it - period.

"We attempted to have our unfinished basement finished in 2020. The project started in June of 2020 and was terminated unfinished in January of 2021. Total cost of the partial project was $75,771. Several issues led to the termination of the project. The primary was lack of actual project management and ability to take responsibility for errors by the contractor, which, in addition to being frustrating, contributed to the unnecessarily long project time of 7 months while still not being finished. Examples include: - An I-Beam for a heavy-bag track was to be installed on the ceiling. It was installed in the incorrect location and extremely poorly, to the point where flanges were overlapping. When confronted, the contractor stated that it just "wasn't finished". However, the correction required the complete removal and re-installation. Then the contractor claimed the issue was due to insufficient instruction supplied, even though all required information was in fact supplied. The installation crew was simply not competent and failed to install as instructed. - Wood panels were put on a large portion of the ceiling. Several conversations in writing instructed that there was to be no more work done after the initial paint as we liked the look as is. When painters were on-site for the walls, it was confirmed with them verbally that the ceiling was complete and not to perform work on them. However, they caulked and painted it anyway. When confronted, the contractor stated it was always known that this work was to be done. He also said it was only painted and not caulked, which was clearly not the case. Additionally, when shown texts and emails where we explicitly requested no more work done to the ceiling and that he also stated it was complete, he simply ignored it. - When ordering a vanity, he sent us to a shop to select one. However, when it came time to need the vanity, we found it had never actually been ordered. The contractor blamed us for not ordering it while at the shop, however the person at the shop later confirmed the hold up was the contractor not confirming the order. These are some of the biggest examples, but there were communication issues throughout the project. The termination of the contact didn't go any better than the rest of the project. We were told up front, in writing, that we would be billed for all services each week for the prior week. However, when we were settling up after the contract was terminated, there were many costs he was back charging for, meaning they were not billed during the week of work as the original contract stated. One of the items had no reciept. One of the bigger issues here was the painting. The painting cost was much too high relative to the original bid price based on actual work performed. When asked for an itemized bill for painting, it included painting work that had not been performed. The contractor ultimately removed the item for which he didn't have a receipt and reduced the paint cost by some amount. It was still not correct, but we agreed to pay to end the situation."

"We hired MH Construction for a kitchen renovation, and we are thrilled with their work! Mike and his team were excellent from start to finish. Mike kept in regular contact with us throughout the process, answering our questions and working out the design. He and his team were amazingly efficient, often getting more completed each day than we’d anticipated, and they were polite, professional, and always kept the work area clean and safe. They also went the extra mile and conscientiously fixed unexpected issues they found, including several smaller electrical and plumbing glitches. Best of all, we couldn’t be happier with the end product: our kitchen is beautiful and more functional than ever. We’ll recommend MH Construction to all of our friends, and we’d be delighted to hire them again in the future!"

Home Building questions, answered by experts

It is a good idea to check in with your local city and state regulations before committing to building a shipping container home no matter where you live. This concept is pretty new across the country, and many places won’t let you build one.

The International Code Council (ICC) offers guidelines for home builders on the safe use of ISO intermodal shipping containers repurposed as building components, which can be helpful to review when planning or designing a shipping container home.

Yes, there are a few different ways you can finance new construction. Some lenders offer new construction loans that cover the building costs and then convert to a standard mortgage once construction is complete. Some custom homebuilders also offer financing options that only require a down payment before you begin the building process. Construction loans are possible, as well, although they typically only cover the building process, and you’ll need to pay in full once the house is completed.

Most contractors aim for about a 20% profit on a job, leaving themselves room for unexpected expenses or delays. After accounting for materials, labor, and insurance, the profit margin for most contractors is between 10% and 20%. Fluctuating costs of materials and labor affect the ultimate percentage.

How long it takes to build an in-law suite will vary by type. The time it takes to build an addition will typically be less than for completely new construction. Expect to spend about two months if you convert a basement, attic, or other existing room in your home. New structures can take up to five months, plus up to two months to receive the required permits.

Major home remodeling projects have some of the highest ROI for adding value to your home. For example, adding a primary bedroom can return about 55% of the investment to build. The cost of a primary bedroom suite averages $62,000—-so the high ROI helps sweeten the deal. However, always make sure to speak with a contractor and architect before adding a new room to your home, as each space affects the layout and aesthetic of your home differently.
