"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! "

Baker & Son Construction has more than 45 years extensive experience in every aspect of building, developing, remodeling and reconstruction. We will get your job done on time and on budget. Our team has the highest standards and stand behind every detail in the construction process. Client trust, attention to detail and a commitment to excellence are our highest goals, and our customers have proved their trust over and over by giving us their return business and recommending us to their friends and family.

"The project was essentially a remodel of a circa 1950's beach cabin with a small addition. We chose Baker and Son on the recommendation of our neighbor who had used them to build a detached garage. Our plans were relatively simple at first: build the addition, expand the kitchen, build a new bathroom and create a new entry. As work was underway, it became clear through the advice of Baker and Son that our kitchen was too big and out of scale for the cabin. We ended up eliminating some walls and opening up the cabin in such a way that created one large room but still a separate kitchen, dining and living. It was a huge improvement to the original design. In addition to the interior work, Baker and Son completely overhauled the exterior which included new windows and siding. New structural headers were required because they didn't exist. Also, since the cabin is post and pier construction, they leveled and strengthen the existing structure. Work included new skirting as well. Their attention to detail was very impressive. They are masters at creative problem solving, patient, responsive and positive. They have a very strong sense of design. We were never pressured into quick decisions. The contract arrangement for our project was essentially time and material because formulating a bid on an old cabin remodel would involve too many unknowns. We agreed to a fair hourly rate and all material and subcontracted work we paid directly with no additional overhead or fee. This saved us money. Since we lived out of town, Baker and Son were so well connected with various vendors and subcontractors, it simplified making arrangements. Now that our project is complete, we are so excited about the end result! We would highly recommend using Baker and Son Construction for any project."

Home Building questions, answered by experts

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.

The national average cost of a building permit is about $1,600, but this number includes extensive renovations. Homeowners typically spend between $150 and $2,000 in general on one or multiple permits for their project. Conversely, permits for simple projects, such as minor electrical renovations, could cost as little as $10.

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

On average, exterior brick siding costs around $18,000 for a 2,500 square foot home. Whereas vinyl costs around $11,000 and engineered wood costs around $4,000 for the same size home. You also need to account for the cost to paint the material afterward.
