Fast, Reliable General Contractor Across Wildomar
Finding a General Contractor who understands Wildomar means finding someone who knows the difference between a flat tract lot and a hillside parcel with grading requirements. Most of the calls we get from Wildomar homeowners start the same way: they have a remodel or addition in mind, and they’re not sure whether the slope behind the house changes everything. It often does. We coordinate the engineering, the permit path through Riverside County, and the long-lead materials so the job doesn’t stall halfway through. Call (341) 895-1170 and we’ll walk you through what your specific property needs.
Why Penhallow Remodeling Riverside Is Wildomar’s Preferred General Contractor Company

We’ve built our reputation in Wildomar the slow way: by giving a written price before work starts and then holding to it. Trevor Nash leads our team, and the standard he set is simple enough that we can repeat it on every job: say the price, show up in the window we gave, and stand behind the work for 365 days after we’re done. Homeowners here have told us that’s what was missing the last time they hired a contractor. We don’t ask you to take the promise on faith. The 365-Day Done Right Promise comes in writing on every Wildomar project, and if a repair fails inside that window, we return at no charge, no service call, no re-inspection fee.
Our crews know the local terrain. That’s not a small thing in Wildomar. When a job site sits on a graded hillside off Grand Avenue or a rural parcel near a septic system instead of a sewer line, the crew needs to understand what’s underground and what’s holding the slope up before the first footing is poured. We do.
Styles & brands we work with






Construction Company in Wildomar
Construction Company work in Wildomar often begins long before anyone swings a hammer. On hillside lots, Riverside County’s grading and hillside ordinances can require retaining walls, slope stabilization, and a geotechnical review before structural work is approved. That’s a gating item. We don’t skip it, and we don’t let it surprise you after the scope is written. Whether the job is a room addition, a garage conversion, or a custom home shell, a construction project on Wildomar soil generally falls between $45,000 and $130,000 depending on square footage, foundation type, and how much site prep the slope demands.
Site and Slope Preparation
The semi-arid heat and Santa Ana wind gusts shape how we schedule work here. Concrete pours get timed for cooler mornings in July and August. Anything that has to hold against wind gets anchored beyond code minimums. If your parcel sits on a hillside, plan for retaining walls and drainage as part of the base contract, not as a change order discovered later.
Draw Schedules and Permitting
We pull permits through Riverside County and keep the draw schedule tied to actual milestones. That means you see where your money goes and when. On hillside work, the geotechnical report can add weeks before approval, and we would rather have that conversation before the contract is signed than after demolition begins.
Remodeling Contractor in Wildomar

Remodeling Contractor work here runs into a different set of realities than what you find in flatter cities like Murrieta or Lake Elsinore. Wildomar’s housing stock splits between older ranch-style homes on multi-acre lots and newer 2000s-era tract homes with stucco exteriors and tile roofs. The older ones, especially the custom builds, are where we do our most interesting work: opening load-bearing walls, reconfiguring kitchens and baths, and matching new millwork to framing that was never perfectly square in the first place. A full kitchen remodel in Wildomar typically runs $14,000 to $45,000. A bathroom remodel lands between $9,000 and $28,000.
Custom Millwork and Cabinetry
We install Wellborn and KraftMaid cabinetry on most Wildomar remodels. When a client wants something built to fit an odd corner or an older home’s out-of-plumb walls, custom millwork order lead times set the schedule, not our labor crews. We’ll tell you that up front, and we’ll hold the price in writing while the materials are in production.
Septic-Aware Additions
Older Wildomar parcels often run on septic rather than sewer. Any addition that adds a bedroom or bath can trigger a septic system review. We coordinate that as part of the permit process, because it changes the project’s order of operations and occasionally its total price.
Trusted Brands We Service in Wildomar
On Wildomar projects we work with materials from recognized trade lines: Wellborn and KraftMaid cabinetry for kitchens and baths, Cambria, Silestone, and Caesarstone counters, plus Kohler, Moen, and Grohe fixtures. We also use Schluter waterproofing systems in showers and Toto and Sterling where the spec calls for it. Every one of those brands carries its own manufacturer warranty, and that sits alongside our written 365-Day Done Right Promise. When something fails, the layers of protection actually mean something. We keep close contact with local Wildomar suppliers so special-order finishes don’t sit in a warehouse graveyard.

AfterCommon General Contractor Problems We See in Wildomar Homes
- Hillside retaining walls ignored until after the scope is set. The county requires them before structural work on many sloped parcels. If they’re not in the original contract, they become a change order, and a change order is exactly what a fixed-price promise is supposed to prevent.
- Lead times on custom millwork and architectural glass underestimated. We see schedules built around labor, then laborIdle while the cabinets are still being milled. We have watched this happen. It always shows in the final fit and finish.
- Slab-on-grade homes with shifting thresholds and cracked tile. The soil here swells and settles with the dry season. A remodel that ignores minor movement will crack again in a year. We address substrate movement before we lay tile.
- Septic systems buried in the plans, literally and figuratively. An addition that expands living space on an old rural parcel can outgrow the septic capacity. That’s a permit issue and a budget issue, and it’s better handled before rough-in.
Pricing for General Contractor in Wildomar, CA
Here’s what we tell homeowners at the kitchen table: the number we give you in writing is the number you’ll pay, unless you change the scope. Not a range that floats, not an allowance that balloons after the tile is pulled. On a fixed scope, the price is fixed. Below are the ranges we see most often in Wildomar’s market for the work we do.
| Project | Wildomar Price Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |

| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
What moves a kitchen remodel toward the top of that range? Cabinet line, countertop material, moving plumbing, and whether we’re re-engineering a load-bearing wall. What moves it toward the bottom? A smaller footprint, stock cabinetry, and leaving the layout alone. Call (341) 895-1170 for a written quote. Estimates are free.

FAQs About General Contractor in Wildomar
They can add retaining walls, drainage systems, and a geotechnical review before any structural work is permitted. We scope those items in the original written price so they don’t arrive later as change orders. Call (341) 895-1170 and we’ll check your parcel’s grading status before quoting.
We install Wellborn and KraftMaid cabinets, and Cambria, Silestone, and Caesarstone countertops. Each carries its own manufacturer warranty alongside our 365-Day Done Right Promise. If you want a specific line, tell us during the estimate and we’ll price it in writing.
We start by checking the septic capacity against the expanded living space. If the addition adds bedrooms or baths, Riverside County may require a septic review, and we handle that inside the permit process rather than as an afterthought.
You apply, the county reviews the grading plan and geotechnical report, and once those clear, structural permits follow. On a sloped Wildomar parcel, expect the geotech review to gate the schedule. We manage the submittals and keep the draw schedule tied to milestones, so you can see where things stand.
We write the scope, then write the price, then let you decide. If you don’t change the scope, the number doesn’t move. Long-lead materials like custom millwork are priced and ordered only with your signed contract. Call (341) 895-1170 to sit down and go over a written quote for your Wildomar project.
