Personalized Construction Process

Our design-build process is the best because it’s personalized to you and your project. Formed over years of local experience serving our neighbors and communities, we will spend as much time as it takes developing our relationship, answering your questions, and ensuring all of your needs are met. Throughout every step below, we are your trusted partner.

Learn Our Process

1. Meet and Greet

We like to meet you in person and really take the time to get to know you to help you determine all of your long-term wants and needs for your project. We answer any questions you may have, but most importantly, we listen. Next, we get to Pro-Line planning!

2. The Ground

We will help you determine where you will be building and coordinate the necessary permissions and permits to do so.

3. The Layout

During this phase, we really dig into your wish list and uncover the optimal floorplan.

4. The Blueprint

Combining engineering, architecture, and our custom design team, we develop the plan that meets your wants and needs.

5. The Bids

Next, we send bids to all subcontractors necessary for getting the job done, such as plumbing, heating and cooling, electrical, flooring, paint, and drywall.

6. The Proposal

Once we have the bids, we draw up your proposal and determine if we can build the building you’re needing within your budget. If not, we reverse engineer to get you the most essential items on your wish list and the project within your budget. This allows you to weigh your options and make an informed decision.

7. The Build

Once the proposal is signed, we’ve made it to the fun part: the build.

Quality Materials Proven To Last

We provide you the highest quality materials that won’t break the bank and the best building techniques that will hold up against the elements. Below are the most common features or materials and their benefits that come with a Pro-Line building.

Materials We Use

All Southern Yellow Pine Lumber

  • Stronger construction
  • Longer life
  • Better appearance (fit & finish)

3 or 4-Ply Laminated Foundation Columns 

  • Greater resilience due to our Treated (CCA) columns, which provide for more penetration than a single post could
  • Greater durability because columns won’t split, weather crack, or deteriorate, which means nails won’t pull out like they will in posts
  • ½ inch Rebar for additional wind uplift protection

Bottom Splash Board

  • EPA compliant MCA treated lumber.
  • 40-year limited warranty against insect and decay

#1 Southern Yellow Pine Laminated (glued & nailed) Wall Columns 

  • Specially designed 3 and 4 ply, 2×6/2×8 columns to meet your building requirements
  • Protective barrier installed between steel and ACQ lumber
  • Steel is attached with stainless steel fastener at all ACQ lumber points

#1 Grade 2×6 or 2×8 Side Girts 

  • Greater stability due to larger girts
  • Increased longevity through the unyielding test of time

Optional Upgrade to Finish Frame Wall Design 

  • No additional framing required for liner coverings
  • Greater strength from girts located 2 foot on center
  • Greater comfort as a result of optional insulation

#1 Grade 2×6 Roof Purlins 

  • A truss system engineered for your building which will meet or exceed all load requirements
  • A greater structural integrity due to our recessed Purlin & Girt system which allows for the steel to fit flush with the roof and wall structure

29-Gauge Roof and Side Wall Steel 

  • High tensile strength E Structural Grade Steel rated at 82,000 psi
  • Accurately measured steel – Our 29-gauge measurement does not include paint or primer in the measurement and is measured at its minimum point
  • Durable ribs formed 9″ on center

All Screw Fasteners on Steel 

  • Greater structural stability – Wood fiber resists the pressure of the nail but secures the threads of a screw
  • Greater weather protection because our screw’s flange and gasket prevent leakage 
  • Stainless steel fasteners used for all roofing, siding, and trim attached to treated lumber

Overhead Doors 

  • A smoothly functioning door backed by a one-year warranty on parts and labor
  • A durable door with a lifetime warranty on its sections

Sliding Doors

  • Choice of steel or wood frame doors

Optional Insulation and Celling Liner

  • Greater environmental comfort by adding a layer of R-19 batt insulation with poly-vapor barrier, or R-23 blow-in wall and exterior house wrap or spray foam ceiling and walls
  • Increased aesthetic value with a 26-gauge, 12-inch on center 1 1/4″ ribbed steel ceiling liner

Any Color Combination and Design 

  • Unique design – It’s your building, so our Pro-Line custom-design team will patiently help you build your dream
  • Distinctive colors of your choice
  • Lasting beauty due to our 40-year limited color warranty assuring you that your paint will not crack, check, peel, flake or chip
