General Contracting Services
Custom remodels, new construction and commercial work from Siemonsma Construction. All in one, from design to build.
Service 01
Kitchen Remodeling
A kitchen remodel involves more trades than any other room in the house: demolition, framing, plumbing, gas, electrical, ventilation, cabinetry, countertops, tile and finish carpentry. Siemonsma Construction manages that work as the general contractor, from coordinating the design and handling permits through to the final walkthrough, so one company is responsible for the sequence and the result.
- Layout changes, including removing or relocating walls
- Plumbing, gas and electrical rough-in and upgrades
- Cabinetry, countertops and backsplash installation
- Flooring, lighting and ventilation
- Appliance installation and connections
- Permit application, plan check and city inspections
Service 02
Bathroom Remodeling
Bathrooms are small rooms with a lot happening behind the walls. Supply and drain lines, waterproofing, ventilation, electrical and tile all have to be right, because mistakes show up later as leaks and moisture damage. Siemonsma Construction runs bathroom remodels as the general contractor, from design coordination and permits through construction and the final walkthrough.
- Primary, guest and powder bathroom remodels
- Shower and tub replacement, including tub-to-shower conversions
- Waterproofing, tile and stone installation
- Plumbing and electrical updates, lighting and ventilation
- Vanities, cabinetry and countertops
- Layout changes and accessibility improvements
Service 03
Whole-Home Remodeling
A whole-home remodel is closer to building a house than to updating a room. Structure, mechanical systems, layout and finishes are all in play at once, and the order in which the work happens matters. Siemonsma Construction is a general contractor with more than 40 years of experience in custom remodels and new construction, and manages each project from the first plans through the final walkthrough.
- Full interior remodels and floor plan reconfiguration
- Structural changes coordinated with a licensed engineer
- Electrical, plumbing and HVAC replacement or upgrades
- Kitchens, bathrooms, flooring, doors, windows and finish carpentry
- Exterior updates, including windows, doors and finishes
- Permit application, plan check and city inspections
Service 04
Custom Homes & New Construction
Building a new home means coordinating an architect, engineers, the city, utility companies and many trades over a long schedule. New construction is part of Siemonsma Construction's work as a general contractor: we work with the design team during planning, handle permit applications and approvals, and run the project from groundbreaking to the final walkthrough.
- Ground-up custom homes
- Tear-down and rebuild projects on existing lots
- Preconstruction input on cost, buildability and schedule
- Coordination with your architect, engineers and interior designer
- Permit applications, city coordination and approvals
- Project management from site work through final inspection
Service 05
Home Additions
An addition has to do two things well: give you the space you need and look as though it was always part of the house. That means matching structure, rooflines, floor levels and finishes, and tying new plumbing, electrical and HVAC into the existing systems. Siemonsma Construction manages additions as the general contractor, from design coordination and permits through construction.
- Room additions and primary suite additions
- Second-story additions
- Kitchen and living area expansions
- Structural engineering coordination for foundations, framing and tie-ins
- Exterior finishes, roofing and windows matched to the existing home
- Permit application, plan check and city inspections
Service 06
Commercial Construction
Commercial work runs on different constraints than residential: lease dates, landlord requirements, accessibility rules, fire and health department reviews, and the cost of every day a business is not open. Siemonsma Construction works with commercial clients as well as homeowners, on office, retail and restaurant projects, providing new construction, remodels and project management as the general contractor.
- Office construction and remodels
- Retail space construction and remodels
- Restaurant construction and remodels
- Coordination with your architect, engineers and interior designer
- Permit application, plan check and city inspections
- Project management from preconstruction through closeout
