"Dalton and his crew were hired to build a roof over an existing deck and replace a rotting fence. From the get-go, they were professional and hard working. On time and efficient, they kept us informed every step of the way. The result? What seems like a beautiful new porch and yard! We even went on to hire them for an additional project, replacing trim on our home. And the cost? Quite reasonable! We highly recommend Elk Valley Construction, LLC!"

"Good people who are easy to deal with.  Framing, siding and non-finish work are their strong suits.  Fit and finish are sub-par.  Attention to detail was hit and miss; some of the misses were very significant in nature.  Job site clean up was not great and the project ran beyond the completion date by more than two months, one week of this was due to a customer change order.  The finished product is sound, passed all inspections without failure and looks good until you examine the details up close.  If you demand high quality fit & finish be sure and put the details in writing up front to avoid disappointment.  Leave no detail out when it comes to materials, no matter how small it may be, right down to the fasteners.  If you are unable to participate at this level, find a higher-end custom home builder who will spend the time necessary on details; it will cost you more of course.  It all comes down to your budget and priorities.

Custom Home Builders FAQs, answered by experts

Renovating or remodeling an existing structure is usually less expensive than the cost to build a new house. That’s because you can save on the costs of new building materials, laying a foundation, framing the entire building, and installing new materials and utilities throughout the house. However, if a home is in very poor condition or is incredibly old, you could spend more on upgrades and restoration compared to building from scratch.

A contractor can install your shipping container home in as little as 90 days. This is notably quick compared to a traditional home build, which can take more than a year (providing there aren’t permitting or construction delays that make the wait even longer). For the quickest installation, choose a prefab container home.

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.

Modular homes are a type of prefab home. Specifically, manufacturers first build modular homes in sections and then deliver them to the job site. The modules, or sections, are usually at least 70% finished before they arrive on your property.

In comparison, prefab homes arrive in panels or segments, and workers assemble them on-site. Generally speaking, modular homes tend to be more durable, and their consistent construction standards may mean you’ll have an easier time getting conventional home loans.

It usually takes around four to six months to build and install a modular home, although your timeline could go up to around eight months if there are delays in the manufacturing or permitting process. Heavy site preparation and foundation pouring can extend that timeline if you need them, as can customizations you want for your modular home. Your modular home company should be able to provide an estimate for the construction timeline before you sign any contracts or agree to any work.
