"My overall experience was fantastic. They painted the outside of the house, the shed, carpentry and the inside rooms. They installed and painted doors and they also did sheet rack. They recommended some colors as well. They left the garage clean because they were storing their stuff in there.  They were trustworthy and they worked straight through from 8-5."

"Pedro renovated about 80% of our 1890s 5-bedroom Victorian home. The work was uniformly excellent and completed on schedule, despite the interruptions caused by the early phases of the pandemic. Pedro is an absolute pleasure to work with, and he maintained excellent relationships with us, the architect, and his subcontractors. His estimate was reasonable as were the change orders. We were lucky to find him!"

Subcontractors FAQs, answered by experts

The most common scale for residential blueprints is 1/4 of an inch equals one foot. This scale is the most popular because it’s easier for everyone involved, from professionals to homeowners, to understand the building’s actual dimensions. Also, it allows blueprints to have the necessary details without cluttering the page.

It is technically possible to draw your own blueprints, but the process is extremely involved and really demands help from an expert. A professional architect has an understanding of design elements, interior design, the functionality of different rooms in a home, and how everything from furniture, outlets, and light switches should be laid out to serve you and your family best. Hiring an architect for blueprints can get expensive, but it’s the most responsible way to begin a new construction project. If you’re keen on DIYing, you could consider starting the process and then having a professional take over.

Costs depend on project complexity, materials, labor, permits, and required revisions.

Adequate storage, workspaces, and energy-efficient systems are key considerations.

There are several different steps in the pole barn building process. First, you’ll need construction plans, which you’ll use to obtain permits. Then, you can clear the land so it’s suitable for building and installing the foundation. Your contractor will frame the barn using large poles, then rough in the plumbing and electricity (if your barn has those elements) before finishing the interior, adding siding, and installing the roof. 

After that, they’ll finish up the electrical work and plumbing and add your windows and doors. You may have a few other finishing jobs to do like painting or waterproofing.
