"????? After another company came in and completely messed up our deck project, we were frustrated and unsure who to trust. Thankfully, we called Modern Building & Contracting, and honestly, we only wish we had found them first! James and Mike came out, listened to our concerns, and immediately put us at ease. From start to finish, they were professional, knowledgeable, and committed to doing the job right. The quality of their workmanship exceeded our expectations, and the finished deck turned out absolutely beautiful. My family and I couldn?t be happier with the results. It?s clear that they take pride in their work and truly care about their customers. If you?re looking for a reliable contractor who delivers quality craftsmanship and excellent customer service, we highly recommend Modern Building & Contracting. Thank you again, James and Mike?we love our new deck!"

"We shopped and spoke with many "facade restoration experts" before choosing to work with High Tech and we are so glad we did our research. Shaiful was by far the most knowledgeable contractor we spoke with and made us feel confident that he was capable of solving our issues.  When it was clear that there was no saving our original cornice, he offered up more than one suitable way forward. We decide to let his crew re-create the original piece from stone. The work they did left us with a beautiful and artistic facade the functions well in collecting rain water from the roof. The crew was respectful, clean and on time. They went above and beyond all of our expectations in touching up every minor detail so that the whole front of the house was left looking brand new. We could not be happier. Our home looks better than we could have imagined. I recommend High Tech Construction with no hesitation.

"Marcus Watson's knowledge and skills were excellent, the work was done very well. He underestimated the time it would take to repair our OLD manufactured home's many faults (the reason for the 4 star-rating), but it is now much cozier, warmer, and stronger, and we greatly appreciate the work he did. The waterproof vinyl "plank" flooring looks terrific, and it's so nice to not have to worry about stepping in a mushy spot, fearing that we'll fall through! We'll be using Marcus when we get ready to do more work on our home!"

"service provider sent by American Home Shield was excellent. The only issue I have with home warranty services is that they do not send their repair companies out on the week-end, even in an emergency. The customer service personnel is less than enthusiastic or helpful."

Custom Home Builders FAQs, answered by experts

How long it takes to build a log cabin depends on a variety of factors, including its size and design, and whether or not you have to clear the land. Construction can take a few weeks for a prefab log cabin on an established site, but up to eight or nine months for a custom cabin on undeveloped land. In comparison, the timeline to build a house is typically four to 12 months.

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

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. 

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.
