Fast, Reliable General Contractor Across Pomona
Hiring a General Contractor in Pomona means finding someone who understands what actually sits behind the walls of homes built before 1960. Most of the single-family houses in 91766, 91767, 91768, and 91769 were framed before modern building codes existed. That includes 1920s Spanish-revival cottages off Lincoln Avenue, 1940s bungalows near Ganesha Park, and postwar tract homes around Phillips Ranch. When you open those walls for a kitchen remodel or bathroom rebuild, you’ll likely find knob-and-tube wiring, galvanized supply lines, or framing that needs reinforcement before the city signs off. Key Step Construction has worked through exactly these conditions across Pomona for years. We plan for them from the first inspection, write allowances into the contract, and price any surprises in writing before work proceeds. Call (855) 382-0824 to schedule your free estimate.
Why Key Step Construction Is Pomona’s Preferred General Contractor Company
Pomona homeowners call us because we’ve earned a reputation for handling the hard parts of remodeling without drama. Our crews know the permitting desk at Pomona City Hall and understand what inspectors look for in older housing stock. That experience shows up in the way we write contracts: every allowance names a specific brand and grade, so you’re never surprised when you choose KraftMaid cabinetry over builder-grade boxes or Cambria quartz over laminate. Noel Garrity built Key Step Construction around a simple structure: Plan it once, build it right. One contractor holds the full scope from roofing and windows down to cabinetry and tile. No juggling three separate crews, no finger-pointing when a schedule slips.
We also carry full-scope accountability that most Pomona remodelers can’t match. GAF and CertainTeed roofing, James Hardie siding, PGT windows, Schluter waterproofing, Belgard pavers. From the roof down to the foundation, one contract covers it.

Construction Company in Pomona
Construction Company work in Pomona typically means taking an older home down to the studs and rebuilding it to current code. A full home remodel in Pomona runs $45,000 to $130,000 depending on scope, square footage, and what the inspection uncovers. Room additions and garage conversions follow the same pattern. The city requires structural review on any project touching load-bearing walls or foundations, and those reviews often reveal conditions the original purchase inspection missed. That’s not a problem if the contractor accounts for it. It becomes a problem when a low bid ignores it.
Older Home Structural Reality
Raised foundations from the 1920s and 1930s are common in Pomona’s 91766 and 91768 ZIPs. Some still have original piers and underfloor framing that was fine for 1940 but does not meet current shear requirements. When we add a second story or reconfigure a floor plan, the structural engineer reviews everything below the subfloor. If we need to reinforce joists, add hold-downs, or replace rotted sill plates, that work gets written into a change order with a firm price before we proceed.
Dual-Permit Work in Pomona
Pomona’s construction market runs on two different engines. There’s the residential stock of pre-1960 single-family homes throughout the Lincoln Park and Wilton Heights neighborhoods. And there’s the commercial and industrial stream along the 10/60 freeway corridor and around the Fairplex. Key Step Construction handles both. The same project manager who coordinates a kitchen remodel in 91767 can run a tenant improvement in a Pomona commercial building without switching gears. Few contractors in neighboring Claremont or La Verne work both sides of that line.
Remodeling Contractor in Pomona
Remodeling Contractor work in Pomona often starts with a simple goal: update a kitchen, rebuild a bathroom, add livable square footage. The actual job frequently involves code-triggered upgrades the homeowner never expected. A kitchen remodel in Pomona runs $14,000 to $45,000. A bathroom remodel runs $9,000 to $28,000. Those ranges reflect the reality that most Pomona homes need electrical and plumbing brought current before finish work begins. In 91766 and 91768, we routinely find original knob-and-tube wiring and galvanized pipes still live in 1920s-era bungalows. City inspectors require those systems replaced and inspected before walls close up. Good contractors know this and price for it. Bad contractors discover it mid-project and hand you a surprise invoice.
Kitchen and Bath Reality Check
When a homeowner in Pomona picks KraftMaid cabinets or Silestone countertops, the contract allowance needs to match that grade. Vague allowances are how remodel quotes move. We write brand-specific allowances, down to the cabinet line and the countertop material, so the number you approve is the number that holds. If the wall opens up and the wiring is worse than expected, you get a line-item change order, approved in writing, before any additional work begins.
Permit-Triggered Upgrades
Opening a wall in a 1925 Spanish-revival cottage off Lincoln Avenue almost always triggers two things in Pomona: a rewire and a repipe. The city will not close the wall on original cloth-wrapped wiring, and galvanized supply lines with pressure loss at the rough-in will not pass. A structural review may also flag the need for foundation work on raised-floor homes. None of this should be a surprise by the time the drywall goes up. It should be in the original plan, priced as a contingency with a hard number attached.
Trusted Brands We Service in Pomona
Our Pomona clients get access to a curated roster of 50+ material brands, including Quikrete and Sakrete for concrete and hardscape work, plus Abodu and Cover for ADU and prefab construction. That means your material choices are guided by contractor expertise, not by whatever a single supplier happens to stock. We pull from the full catalog across cabinetry, countertops, plumbing fixtures, roofing, windows, doors, siding, fencing, and hardscaping. Built to the brand’s spec, installed to Pomona’s code.

AfterCommon General Contractor Problems We See in Pomona Homes
- Hidden knob-and-tube wiring in 1920s bungalows. The walls look fine on the surface. Open them and we find original wiring that must be replaced before the inspector signs off. This is the single biggest reason a Pomona remodel quote moves.
- Galvanized supply lines with failing pressure. These pipes corrode from the inside out. A repipe becomes mandatory on any significant remodel in the older neighborhoods around Ganesha Park and Wilton Heights, not optional.
- Raised foundations with undermanaged moisture. Clay soils in Pomona shift with wet and dry seasons. Subfloor rot and weakened piers hide under those homes. A pre-bid structural review catches it before the project starts.
- Vague allowances that force mid-project decisions. If the contract says “cabinets” without naming a grade, you’ll get hit with a change order the moment you pick anything above builder basic. We write brand-specific allowances so that never happens.

FAQs About General Contractor in Pomona
Because homes built in the 1920s and 1930s in Pomona’s 91766 and 91768 ZIPs typically still have original knob-and-tube wiring and galvanized plumbing inside those walls. Pomona’s building code requires both systems replaced and inspected before any remodel can pass final inspection. The discovery happens the moment a wall opens. A contractor who knows Pomona will include contingency language and written allowances for this from day one. Call (855) 382-0824 to talk through what your home likely has behind its walls.
A permitted remodel in Pomona means the electrical, plumbing, and structural work gets inspected at rough-in and at completion. That creates a paper trail proving the work was done to current code, which matters when you sell the home or file an insurance claim. Unpermitted work in Pomona creates liability and can hold up a future sale. Key Step Construction pulls permits and schedules inspections on every project.
We inspect before we bid, so most conditions are caught before the contract is signed. For anything that surfaces after walls open, we write a change order with a firm, line-item price and get your written approval before any additional work starts. On a 1925 Spanish-revival cottage off Lincoln Avenue, our crew found knob-and-tube wiring spliced to newer romex and galvanized pipes with pressure loss at the rough-in. We wrote a change order for a permitted rewire and repipe, priced and approved in writing before we closed anything up. No surprises at final payment.
Yes. Pomona’s construction market runs on both residential homes and commercial work tied to the Fairplex and the 10/60 freeway corridor. Key Step Construction manages both under one project structure. A homeowner in 91767 and a tenant improvement along the freeway get the same inspection-first, written-allowance approach. Call (855) 382-0824 to discuss your project type.
Expect clearly defined milestones tied to work completed, not arbitrary dates. For a Pomona remodel with potential hidden wiring or plumbing, we build a contingency line into the contract with a hard number. Any change orders get priced, approved in writing, and added to the schedule before the work happens. That keeps the draw schedule predictable even when the house throws you a curve. Estimates are free at (855) 382-0824.
