Trusted General Contractor for Los Angeles Homeowners
Hiring our General Contractor in Los Angeles means trusting someone with your largest asset, your home, and often your family’s daily safety. Mason Remodeling Co Los Angeles has provided general contracting, bathroom remodeling, and whole-home remodeling since 2004 as part of the Threshold Group family of home-service companies. We put every price in writing before work starts, identify every crew member by name and photo before they arrive, and back completed work with a 365-Day Done Right Promise. If something is not right within a year of completion, we make it right at no cost to you. Call (213) 632-5711 to discuss your project and get a written, no-obligation estimate.
Construction Company

A construction company is the entity that plans, coordinates, and executes building or renovation work, from structural framing to final finishes. You need one when a project involves multiple trades, permits, structural changes, or work that must meet California building code. Mason Remodeling Co Los Angeles operates as a construction company that handles kitchens, bathrooms, additions, conversions, and the coordination of electricians, plumbers, and inspectors so you never have to manage them yourself. Kitchen remodels in Los Angeles typically run $16,520 to $53,100 depending on cabinet grade, appliance moves, and whether walls come down. Bathroom remodels run $10,620 to $33,040. A home addition starts around $53,100 and can reach $153,400 for a full second-story build.
Permit Coordination
Los Angeles building permits are not optional for structural, electrical, or plumbing work, and city inspectors review every stage before it is covered up. We pull permits, schedule inspections, and make corrections when an inspector flags something. You receive a written line-item estimate so the permit costs are visible before you sign anything.
Trade Management
A construction company is only as good as the people it sends, and we verify every electrician, plumber, and tile setter by name, photo, and background check before they walk through your door. You will know who is coming and when. No anonymous subcontractors, no “someone will be there Tuesday.”
Styles & brands we work with







Remodeling Contractor
A remodeling contractor specializes in transforming existing spaces rather than building from the ground up, and that is where most Los Angeles homeowners put their money. You need one when a kitchen, bath, or entire floor plan no longer functions for how you actually live. Mason Remodeling Co Los Angeles performs remodels with a written price delivered before a single tool is unpacked, backed by the 365-Day Done Right Promise. A small bathroom remodel in Los Angeles typically costs $5,900 to $14,160. A small kitchen remodel runs $10,620 to $23,600. Cabinet installation alone ranges from $4,720 to $15,340 depending on catalog or custom sizing.
Written Price Before Work Starts
We do not give verbal estimates that grow on the final bill. Every remodel receives a written price before work begins, including materials, labor, permits, and any known complications found during the walkthrough. If we find something behind the walls, we stop and tell you in writing what it costs before touching it.
One-Year Craftsmanship Coverage
Our workmanship is covered for 365 days from the completion date. If a tile cracks, a cabinet door sags, or a fixture loosens within that year, we return and fix it at no charge. The guarantee terms are written, dated, and given to you at project close.
Licensed General Contractor

A licensed general contractor holds the state-issued credential required to perform residential construction work above a certain dollar figure in California, and hiring an unlicensed operator can void your homeowner’s insurance and leave you liable for injuries. You need our General Contractor in Lawndale for any job involving structural framing, load-bearing wall removal, foundation work, or permit-pulling in Los Angeles. You need a licensed general contractor for any job involving structural framing, load-bearing wall removal, foundation work, or permit-pulling in Los Angeles. Mason Remodeling Co Los Angeles carries the proper licensing and pulls permits on every job where the city requires them. Garage conversions in Los Angeles run $35,400 to $94,400. ADU construction runs $106,200 to $259,600, driven by foundation, utility, and seismic requirements.
Why Licensing Matters
An unlicensed contractor cannot pull a permit in Los Angeles, which means the work is invisible to the city, uninsurable, and a liability if you ever sell the home. Lenders and buyers ask for permit history. We pull permits and pass inspections as standard practice, and you get copies of every approval.
Insurance and Protection
We carry insurance and bonded coverage so a jobsite injury or property damage is not your financial burden. If a worker is hurt on your property and the contractor is not insured, the homeowner can be sued directly. We will show you our paperwork before the first day of work.
Residential General Contractor
A residential general contractor focuses specifically on homes rather than commercial buildings, which matters because Los Angeles residential codes differ sharply from commercial in egress, fire safety, and structural requirements. You need our General Contractor in Lynwood when you are planning a kitchen remodel, bathroom rebuild, garage conversion, or whole-home renovation. You need one when you are planning a kitchen remodel, bathroom rebuild, garage conversion, or whole-home renovation. Mason Remodeling Co Los Angeles has worked residential projects across the city since 2004, from Craftsman bungalows in Hancock Park to mid-century ranches in Culver City and 1920s Spanish-style homes in West Hollywood. Roof replacements run $9,440 to $23,600. Impact window installation runs $9,440 to $29,500, and that price reflects material plus the labor of retrofitting older framing.
Older Home Experience
Los Angeles is full of homes built before modern framing standards, and many have settled foundations, non-standard stud spacing, and old knob-and-tube wiring hiding behind the walls. We plan for what we find, not just what is on the blueprint. When we open a wall in a 1927 Spanish Revival in Hancock Park, we expect surprises and we price discovery into the initial estimate rather than springing change orders on you later.
Structural Awareness
Removing a wall in a Los Angeles home often means adding a beam, and a beam needs an engineer’s stamp and city approval. We bring in licensed engineers when the job requires it and include their fees in the written estimate. No guessing, no “we’ll figure it out as we go.”
Hire a General Contractor

To hire a general contractor is to choose the person who will be in your home for weeks, not an afternoon, and in Los Angeles that choice is also a security decision. You need someone who proves who is coming, puts the price in writing, and stands behind the work. Mason Remodeling Co Los Angeles follows the Threshold Standard: every technician is background-checked, identity-verified, and introduced to you by name and photo before the visit, then shows a photo ID badge at the door on arrival. Paver patio installation runs $4,130 to $12,980. Driveway replacement runs $5,900 to $16,520, and concrete driveways run $5,310 to $14,160.
Who Is Coming to Your Door
You will receive the name and photo of each crew member before they arrive. When the doorbell rings, the person standing there matches the photo we sent, wears a clean marked uniform, and carries a photo ID badge. If someone shows up unannounced and unverified, that is not us.
The Interview Question That Matters
Ask any contractor you are considering: will the price change after you open the walls? A honest answer is “maybe, but you will know in writing before we proceed.” That is our answer, and it is the only one that protects a Los Angeles homeowner from the most common remodeling complaint: a final bill 30% higher than the verbal estimate.
General Contractor Services
General contractor services span everything from small fixture swaps to full home additions, and in Los Angeles the most requested projects cluster around kitchens, bathrooms, and converting underused space. See our General Contractor Maintenance Checklist for Los Angeles Homeowners to plan your project before calling. Mason Remodeling Co Los Angeles offers these services with written pricing, permit handling, and the 365-Day Done Right Promise on every job. Countertop installation runs $2,360 to $7,670 depending on whether you choose a prefab material or a slab from Cambria, Silestone, or Caesarstone. Backsplash installation runs $945 to $2,950. Walk-in shower installation runs $5,310 to $14,160, and tub-to-shower conversions run $4,130 to $11,800.
Kitchen and Bath Remodeling
Most Los Angeles kitchen remodels involve opening a wall or two, rearranging the plumbing, and upgrading to specification-grade cabinetry from KraftMaid or Wellborn. Bathrooms often mean removing a tub and building a curbless shower with a Schluter strip, the metal trim that seals the edge where tile meets flooring. We walk you through every material decision in plain language and show you samples before anything is ordered.

Additions and Conversions
A garage conversion or ADU is usually the fastest way to add living space to a Los Angeles lot, and both require city permits plus utility upgrades. We handle the full scope: framing, electrical, plumbing, insulation, drywall, and the final inspection sign-off. A garage conversion ranges from $35,400 to $94,400, and an ADU from $106,200 to $259,600 depending on site conditions and foundation work.

Brands We Service
We work with prefab and panelized home systems from Abodu and Cover, both of which offer factory-built ADU structures designed for faster permitting and on-site assembly in California jurisdictions. The benefit of these units is speed and predictable engineering, but the site work still requires a general contractor who knows Los Angeles foundations, utility connections, and drainage requirements. We handle that scope and coordinate directly with your chosen manufacturer.
For homeowners considering high-performance panelized or modular systems from Dvele or Mighty Buildings, we provide the on-site construction management that ties factory-built components to your Los Angeles lot. These systems have specific anchoring, craning, and finish-work requirements that a conventional framer may never see. Whether you have an Abodu, Cover, Dvele, Mighty Buildings system, or any other make, we can coordinate the ground-up scope and deliver it under a written price.

AfterSigns You Need a Pro Right Now
- You see a horizontal crack in a foundation wall. Vertical hairline cracks are common in Los Angeles slab foundations due to soil movement, but horizontal cracks or cracks wider than a quarter inch signal lateral pressure that needs an engineer’s assessment. Waiting turns a repair job into a structural rebuild.
- Your floors slope noticeably toward one corner. Some settling is normal in a city built on expansive clay, but a floor that drops more than an inch over ten feet can mean joist damage, a shifting foundation, or previous unpermitted work. A licensed general contractor can identify which issue you have and what fixing it costs before it worsens.
- A room addition or conversion was done without permits. Los Angeles home sales routinely stall or collapse when buyers discover unpermitted square footage. If you inherited unpermitted work when you bought the house, it is worth the cost of bringing it up to code now rather than negotiating it away at a future sale.
- Your kitchen or bath has moisture stains on the subfloor. Staining under a sink or near a tub means water has been sitting where it should never be, which in Los Angeles homes means dry rot, mold, and likely subfloor replacement. Opening that floor and fixing the source is a general contractor job, not a caulk-and-paint fix.
- You plan to remove a wall that may be load-bearing. If the wall runs parallel to the roof ridge or sits directly above a foundation beam, assume it is structural until an engineer says otherwise. Removing it without a proper beam and permit can put your family’s safety at risk and create a disclosure nightmare when you sell.
Our Process, Step by Step
- 1
Call and talk to a person. A live person answers our phone 24 hours a day, 7 days a week, including weekends and holidays. You describe your project, ask your questions, and schedule a site visit at a time that works for you. No call trees, no voicemail loops, no waiting until Monday.
- 2
Site walkthrough and scope review. We visit your Los Angeles home, look at the space, and listen to what you want. We check access, existing conditions, and anything structural that could affect the plan. You will know who is coming before the visit: name, photo, and what time to expect them.
- 3
Written estimate, line by line. You receive a written price before any work begins. Every line item is separated: materials, labor, permits, disposal, and any known variables. If something is unknown until we open a wall, we tell you that in the estimate and explain how discovery pricing works.
- 4
Permits and scheduling. We pull permits from the Los Angeles Department of Building and Safety, schedule inspections at each required stage, and coordinate all trades around those inspections. You receive copies of every permit and every pass or correction notice. Nothing gets covered up without an inspector’s approval.
- 5
Walkthrough and written guarantee. When the work is done, we walk the project with you and address any remaining punch-list items. You receive a written guarantee stating what is covered, what is excluded, and for how long: 365 days from the completion date. If anything fails within that year, we return and fix it at no cost.
How Much Does General Contractor Cost in Los Angeles?
A typical kitchen remodel in Los Angeles runs $16,520 to $53,100 depending on cabinet grade, countertop material, appliance relocation, and whether structural changes are involved. A bathroom remodel runs $10,620 to $33,040, with small bathrooms at $5,900 to $14,160. Home additions start at $53,100 and reach $153,400 for larger second-story builds. Garage conversions run $35,400 to $94,400, and a new ADU runs $106,200 to $259,600 based on foundation conditions, utility connections, and finish level.
What affects the price most in Los Angeles is existing condition, not square footage alone. Older homes in Hancock Park or West Hollywood often have outdated wiring, non-standard framing, and hidden water damage that must be corrected before new work can pass inspection. A second factor is material grade: KraftMaid cabinetry costs less than full custom, Cambria quartz runs differently than Caesarstone, and Kohler fixtures span a wide range. The third factor is permit and engineering fees, which are fixed city costs but vary by scope.
To avoid overpaying, get a written line-item estimate and compare it against another written estimate, not a verbal number. Ask what happens when the contractor finds something unexpected behind the walls. A contractor who cannot explain discovery pricing in plain English is one you should not hire. Our estimates are free, they are written, and they include everything we can see during the walkthrough.
