Fast, Reliable General Contractor Across Muscoy
If you’re searching for a General Contractor in Muscoy, you likely have a project in mind and want to know what it’ll cost, who’s showing up, and whether the work will hold up. We give you a written price before any demo starts, a verified crew with names and photos sent to you in advance, and a 365-Day Done Right Promise on every job. Call (803) 680-2547 for a free estimate on your Muscoy project, whether it’s a kitchen remodel, a garage conversion, or a full home addition.
Most Muscoy homes are older, unincorporated San Bernardino County stock. That means additions, garage conversions, and even some kitchen bump-outs often need a county building permit and inspection sign-off because the city has no separate building department of its own. We know that process cold, and we’ll walk you through it before you spend a dollar.
Why Mason Remodeling Is Muscoy’s Preferred General Contractor Company
Mason Remodeling has handled general contracting, bathroom remodeling, and whole-home remodels since 2004 as part of the Threshold Group family of home-service companies. Muscoy homeowners call us for one reason that keeps coming up: they want to know exactly who is walking through the door and exactly what the final bill will say. We do both as standard practice, not as a favor.
Since 2004, we’ve had one rule: written price before any work starts. On every project. Not a verbal ballpark that grows into a change-order stack. Not an estimate that quietly doubles when the cabinets get picked. A written price, delivered before a single tool is unpacked. If something is excluded, it’s written down. If it’s included, it’s written down too.
Every crew member we send to Muscoy goes through The Threshold Standard: background-checked, identity-verified, uniformed, and carrying a photo ID badge. You’ll get the technician’s name and photo before the visit. That matters when you’re home alone, when your kids are napping upstairs, when a stranger at the door is a real decision and not a formality.
Our customers in Muscoy and across the Inland Empire keep us honest. A live person answers every call, 24 hours a day, 7 days a week, including weekends and holidays. No call trees. No voicemail loops. No “we’ll get back to you Monday.”
Styles & brands we work with
Construction Company in Muscoy
As a Construction Company serving Muscoy, we scope and build projects that usually mean structural work: home additions, ADUs, garage conversions, and whole-home remodels where walls move or slabs get opened. A Muscoy homeowner calls us when the job is too big for a handyman and too important to trust to an unlicensed crew that promises “county doesn’t check.” The work typically ranges from $30,000 to $80,000 for a garage conversion and $45,000 to $130,000 for a home addition, depending on square footage, foundation condition, and finish level.
Permitting Through San Bernardino County
Unincorporated Muscoy means San Bernardino County’s building department governs permits and inspections. We pull the permit, schedule the inspections, and manage the corrections. When the inspector signs off, the work is legal and resellable, which is exactly what a future buyer’s lender will ask about.
What Actually Gets Built
A typical Muscoy addition starts with site layout and foundation work, then framing, rough plumbing and electrical, insulation, drywall, finishes, and final inspections. On older slabs near Cajon Blvd, we sometimes find cracking or settled sections that require subfloor repair before framing begins. That condition gets scoped into the written price before demo, not added as a surprise after.
Remodeling Contractor in Muscoy
As a Remodeling Contractor in Muscoy, we focus on kitchens and bathrooms inside the existing envelope, plus finish-level whole-home updates. That’s where homeowners see daily payoff: new cabinets, counters, tile, fixtures, lighting, and layout changes that make a 1960s ranch or 1970s frame home live like it was built this decade. A Muscoy kitchen remodel typically runs $14,000 to $45,000. A small kitchen lands at $9,000 to $20,000. Bathrooms range from $9,000 to $28,000 for a full remodel, and $5,000 to $12,000 for a compact guest or hall bath.
What Drives a Remodel’s Cost in Muscoy
Cabinet and counter allowances are the biggest swing factor. A homeowner who picks stock builder-grade boxes will pay less than one who selects KraftMaid cabinetry and Cambria quartz. We write the allowance into your written price before demo, so the selection happens with real numbers attached, not a blank line that becomes a change order later.
Older Home Conditions
Homes in Muscoy off State Street and around the 210 frontage often sit on original slabs with aged subfloors and plumbing rough-ins that have never been touched. In kitchens, that means rotted cabinet bases under old sinks. In bathrooms, cracked shower pans with water damage behind the tile. We inspect before we price. If we find it, it’s in the written scope. If we don’t find it and it appears after demo, we document it, show you photos, and agree on the cost before we proceed.
Trusted Brands We Service in Muscoy
We work with specification-grade material partners so Muscoy homeowners don’t get pushed toward builder-grade by default. For cabinets, we install KraftMaid and Wellborn. For counters and surfaces, Cambria, Silestone, and Caesarstone. For plumbing fixtures, Kohler, Moen, Toto, and Grohe. For hardscape and outdoor work, we use Belgard, Unilock, and Techo-Bloc. For concrete and repair work, Sakrete products show up regularly on our Muscoy job sites. We coordinate ordering and delivery so materials arrive when the schedule calls for them, not three weeks after the framing crew leaves. That keeps a Muscoy ADU or kitchen remodel moving instead of stalling on a backordered vanity.

AfterCommon General Contractor Problems We See in Muscoy Homes
- Skipped county permits on conversions. Some contractors assume that because Muscoy is unincorporated, nobody checks. Then the homeowner goes to sell and the title company flags unpermitted square footage. We pull the San Bernardino County permit on every job that needs one, and we keep the inspection card with the project file.
- Thin allowances on kitchens and baths. A remodel priced with $800 for cabinets and $600 for counters sounds great until the homeowner picks real KraftMaid and Cambria. We write realistic allowances into the Muscoy price up front, matched to the brands you actually want.
- Rotted subfloors and cracked slabs. Older Muscoy homes on slab foundations hide problems under tile and carpet. A contractor who prices without looking underneath torches the budget at demo. We check for rot, cracking, and load-bearing wall issues before the estimate goes to writing.
- Draw schedules that fund everything up front. A common complaint is paying 50% or more before a single stud goes up. We structure draws so payments match completed milestones: foundation pass, framing pass, rough-in pass, final pass. You’re never funding work that hasn’t happened.

FAQs About General Contractor in Muscoy
Yes, almost always. Muscoy is unincorporated San Bernardino County, so there’s no city building department. San Bernardino County’s building division handles permits and inspections. Additions, garage conversions, and most structural changes need a county permit and an inspection sign-off. Skipping it creates resale and insurance problems later. We pull the permit and manage inspections for you. Call (803) 680-2547 and we’ll confirm what your specific project needs.
Cabinet grade, countertop material, electrical work, and whether you’re moving plumbing. A Muscoy kitchen with builder-grade cabinets and laminate counters lands near the low end of the $14,000 to $45,000 range. KraftMaid cabinets with Cambria quartz and a plumbing move push toward the top. We write allowances in plain language so you see exactly what each choice costs. Call (803) 680-2547 for a written price on your kitchen.
A Muscoy bathroom remodel typically takes 2 to 4 weeks once the county permit is in hand. A kitchen runs 4 to 8 weeks. A home addition or ADU takes 3 to 6 months depending on foundation work and inspection scheduling. Permit review through San Bernardino County can add 2 to 6 weeks before demolition starts. We build that into your schedule from day one.
Rotted subfloors under old kitchens and baths, cracked or settled slabs, outdated wiring that won’t pass inspection, and hidden plumbing corrosion. These show up after demo on older Muscoy homes. If they appear, we document them, show you what we found, and get written agreement on the added cost before proceeding. You’ll never get a surprise invoice. Call (803) 680-2547 to scope your project properly up front.
No. Planned construction, like a Muscoy kitchen remodel or a room addition, is not same-day work and anyone who promises that is not being honest. We schedule your project, order materials to arrive in sequence, pull permits, and work a realistic calendar. What we do guarantee: a written price before we start, a verified crew with names and photos, and a 365-Day Done Right Promise on the finished work.
On a 1960s ranch off the 210 frontage near Cajon Blvd in Muscoy, we turned a dark two-car garage into a permitted bedroom-and-bath ADU. That job meant framing, rough-in plumbing and electrical, and a new subfloor over the slab. We pulled the San Bernardino County permit, set a draw schedule so the homeowner wasn’t funding the whole job up front, and worked the punch list down to a clean inspection sign-off. The homeowner picked KraftMaid cabinets and a Kohler shower valve for the bath, and we wrote every allowance and change order in writing before the first stud went up. That’s how work gets done in Muscoy: priced honestly, permitted correctly, and finished clean.
