 Trustindex verifies that the original source of the review is Google. We had the best experience building our 3400 sq ft home with SEMCO! From picking plans to our final walk through we were greeted with warm, clear and anxiety-reducing communication.  My husband literally brought them a house plan on a napkin and they made it come to fruition, WOW!! This is our second time building a custom home with SEMCO and they did not disappoint. Love the family atmosphere and decades of experience they bring to the table. When we were unsure of selections, they knew what would work and look good! Huge relief for someone who knows nothing but wants to pick and do the right things for our home. Beautiful experience! Thank you so much SEMCO!!!

 Trustindex verifies that the original source of the review is Google. SEMCO remodeled our home in 2024. The work included a complete kitchen makeover to include a change to a gas range, new cabinets, new island with power, exterior wall repair, removal of an existing interior wall and building a pantry. The work continued into all new exterior doors, removal of popcorn ceilings, retexture and paint, new flooring throughout, widening interior door openings and installing new doors, upgrading the home electrical and custom building new interior stairs. The craftsmanship of their work is superb. The SEMCO folks and their team of craftsmen and designers took our ideas, provided input and alternatives, and helped us turn our home into what we had envisioned after living in the home for 20 years. One year has passed and we wouldn’t wish for anything different and are still extremely pleased with how it turned out. Small suggestions during the construction phase from the team are proving their worth. We had considered moving into a newer home, but really loved our current location, and now have the best of both worlds. Many thanks .

Got Questions? Here’s Why SEMCO Stands Out:

Can I build on my own lot or use a SEMCO plan?
Yes – we offer flexible options: build on your land, choose a SEMCO plan, bring your own architect or allow Semco do draw up a custom plan with you.
How much does a custom home cost?
It varies: cost depends on lot location, square footage, floor plan, finishes, and upgrades. We walk through a features checklist and tailor a price to your budget.
What’s the timeline to build?
Typically 9–11 months, from foundation to final walkthrough. Factors like weather or special-order materials can affect the schedule. Semco Construction
Do you provide a warranty?
Absolutely. You receive a 1-year written builder warranty plus a 10-year structural warranty via Residential Warranty Corporation. Semco Construction
Can you handle remodeling or additions?
Yes – we provide full home renovation services, including kitchen and bathroom remodeling, room additions, painting, and even barndominium conversions. Semco Construction
Will I get regular updates?
Yes. Our team communicates throughout design, build, and closing, and we schedule more than 7 walkthroughs at various stages of construction, including a final walk through and home demonstration.
