Trusted General Contractor for Torrance Homeowners
Hiring a general contractor in Torrance usually means you need someone to pull together permits, trades, materials, and a schedule without letting any of it slide. We do that as a single accountable team. Mason Remodeling Co Torrance has operated since 2004, led by Isaac Pruett, with every project priced in writing before work begins and every crew member identified by name and photo before they reach your door. Call (424) 337-6939 for a free estimate.

Construction Company

A construction company handles the structural, framing, and build work that sits behind the finishes you actually see. You need one when a project involves load changes, new foundations, major plumbing or electrical reroutes, or anything that requires permits and inspections. Mason Remodeling Co Torrance functions as our General Contractor in Torrance for Torrance homes, managing everything from a kitchen tear-out to a full addition. Typical Torrance projects fall into ranges like $14,000 – $45,000 for a kitchen remodel, $45,000 – $130,000 for a home addition, and $90,000 – $220,000 for ADU construction. What sets us apart is the paperwork: a written price before demolition, a written guarantee after, and the 365-Day Done Right Promise on every job.
Permitted Structural Work
Some Torrance neighborhoods have specific requirements for additions, especially in areas near the coast where wind and seismic codes apply. We pull permits, schedule inspections, and stay on site through final sign-off. No homeowner should have to chase down an inspector or wonder whether the footing was poured to code.
Materials and Trade Coordination
We coordinate masonry, framing, rough electrical, plumbing, and finish trades under one contract. That means one point of contact, one schedule, and no finger-pointing between subs. Isaac Pruett reviews every schedule weekly and updates homeowners by phone, not by text chain.
Styles & brands we work with







Remodeling Contractor
A remodeling contractor focuses on changing what already exists: reworking rooms, moving walls, replacing finishes, and upgrading systems inside the existing footprint. You need one when the shell of your Torrance home is sound but the layout, function, or appearance no longer matches how you live. Mason Remodeling Co Torrance handles kitchen remodels at $14,000 – $45,000, bathroom remodels at $9,000 – $28,000, and small bathroom remodels at $5,000 – $12,000, with the exact figure in writing before any tool is unpacked. Cabinet installation runs $4,000 – $13,000, and countertop installation $2,000 – $6,500, depending on material and linear footage.
Kitchen and Bath Remodels
These are the two rooms where Torrance homeowners see the most return and the most daily frustration when done wrong. We handle full gut-and-replace jobs as well as lighter refreshes. Every kitchen or bath quote includes a line-item breakdown: demolition, rough-in, finish materials, and labor.
Whole-Home Remodels
When a house needs new systems, new layout, and new finishes throughout, it is really a series of small projects that must hold together as one. We sequence the work so the family can stay in the home as long as possible. Whole-home work in Torrance is priced per scope, never as a vague square-foot number that grows later.
Licensed General Contractor

A licensed general contractor holds a state contractor’s license and carries the insurance and bonding required to pull permits and perform work legally in California; see our General Contractor Maintenance Checklist for Torrance Homeowners for what to verify before hiring. You need one for any project where a permit is required, which covers most structural, plumbing, and electrical work in Torrance. Mason Remodeling Co Torrance operates under Threshold Verified standards, meaning written pricing, identity-verified crews, and a written guarantee are the baseline, not an upgrade. Our bathroom remodel work runs $9,000 – $28,000, walk-in shower installation $4,500 – $12,000, and tub-to-shower conversion $3,500 – $10,000.
Permit and Inspection Handling
Torrance building codes are specific, and inspectors here look closely at waterproofing, strapping, and energy compliance. We handle the permit application, the inspections, and the corrections if any are flagged. Homeowners get a copy of every permit and final sign-off.
Insurance and Written Guarantee
Every project is backed by a written guarantee with plain-language terms: what is covered, what is excluded, and for how long. If a repair or installation fails within 365 days of completion, we return at no charge. That is the 365-Day Done Right Promise, in writing, every time.
Residential General Contractor
A residential general contractor works exclusively on homes rather than commercial buildings, and understands the codes, materials, and daily realities of occupied living spaces. You need one when you are adding a room, converting a garage, or remodeling a kitchen you still have to cook in. Mason Remodeling Co Torrance, also your Lomita General Contractor, has spent two decades on Torrance homes, from Old Torrance bungalows to newer builds in South Bay tracts. Garage conversions run $30,000 – $80,000, home additions $45,000 – $130,000, and driveway replacement $5,000 – $14,000. Every quote is written, and every crew member arrives in a marked uniform with a photo ID badge at the door.
Additions and Garage Conversions
These projects test a contractor’s honesty because so much of the work is behind drywall. We photograph every stage of framing, insulation, and rough-in before it gets covered. Torrance homeowners get a digital folder of those photos at the end of the job, so they know what is behind their walls.
Exterior and Hardscape Work
Driveways, patios, and fencing sit outside but affect how the whole property holds up. Paver driveway installation runs $7,000 – $18,000, concrete driveways $4,500 – $12,000, and paver patios $3,500 – $11,000. We handle drainage and base prep properly, because in Torrance’s clay-heavy soil, a patio that shifts after one rainy season is a warranty claim waiting to happen.
Hire a General Contractor
Hire a general contractor when the job involves more than one trade, a permit, or a budget you cannot afford to see double mid-project. You need one before you tear anything out, because the order of operations determines whether the project costs what was quoted. Mason Remodeling Co Torrance, our General Contractor in Wilmington and surrounding South Bay cities, gives every homeowner a written price before work starts, never as a favor and never as a verbal range that shifts when the bill arrives. Roof replacement in Torrance runs $8,000 – $20,000, window replacement $4,500 – $15,000, and impact window installation $8,000 – $25,000.
Questions to Ask Before You Sign
Ask whether the price is written, whether the crew is background-checked, and what the guarantee actually covers and for how long. If a contractor hesitates on any of those, that is your answer. We hand you the written price, the crew’s name and photo, and the guarantee terms up front.
How We Vet Our Crews
Every Mason Remodeling technician is background-checked and identity-verified through the Threshold Standard. You receive the technician’s name and photo before the visit, and they show a photo ID badge at your door. No stranger walks into a Torrance home under our name.

General Contractor Services
General contractor services cover the full span of residential construction: kitchens, baths, additions, roofing, windows, driveways, and whole-home remodels. You need them when a project touches more than one trade or requires coordination between materials, permits, and people. Mason Remodeling Co Torrance delivers all of this from one contract, with one accountable team led by Isaac Pruett. Backsplash installation runs $800 – $2,500, kitchen island installation $3,000 – $10,000, and bathroom vanity installation $800 – $3,000. The written price includes labor, materials, and any subcontractor work, so the final bill matches the first quote.
Interior Finish Work
This is where Torrance homes show their age: countertops, backsplashes, vanities, shower surrounds. We install specification-grade materials from partners like Cambria, Silestone, Moen, and Kohler. Homeowners get the exact product name and model number in the quote, not a generic “tile” or “faucet” line item.

Roofing and Windows
Roof repair in Torrance runs $400 – $1,800, tile roof repair $600 – $2,500, and metal roof installation $15,000 – $40,000. Windows, especially impact-rated ones for coastal wind zones, are priced per opening and per frame condition. We use GAF, CertainTeed, and Owens Corning roofing products and ECO Window Systems or ES Windows for fenestration work.

Brands We Service

We install and service ECO Window Systems products across Torrance, including their thermally broken aluminum frames that hold up well against South Bay salt air. Our crews are trained on their installation specs, including proper flashing and sealant sequencing, which is where most window failures actually start. We also work regularly with ES Windows on larger custom openings where the frame engineering matters.
For CGI impact-rated windows, we understand the specific anchoring and glazing requirements for coastal wind zones, and we handle the permitting paperwork that comes with structural window changes. Whether you have ECO Window Systems, ES Windows, CGI, or any other make, we can install, replace, and service it under one written warranty.

AfterSigns You Need a Pro Right Now
- Water staining on ceilings or walls. This can mean roof damage, a failed window seal, or a plumbing leak inside a wall cavity. What you see on the surface is usually smaller than what is happening behind it.
- Doors or windows that stick seasonally. Torrance’s clay soil expands and contracts with moisture, and that movement can shift framing. Sticking doors and windows often signal a structural issue that needs a contractor’s assessment, not just a plane to the jamb.
- Cracks wider than a quarter inch. Hairline cracks are normal settling. Wider cracks, especially near corners or above doors, can mean foundation or shear-wall problems. You want a licensed general contractor in Torrance to look before it affects the structure.
- Shower leaks or soft spots in flooring. A leaking shower pan or failed waterproofing rots subfloor and framing. By the time you feel the soft spot, the repair is usually bigger than a re-grout.
- Electrical flicker or breakers that trip repeatedly. This is not a DIY situation. Persistent breaker trips can mean overloaded circuits, damaged wiring, or failing panels. A licensed contractor will bring in the right electrician under the right permit rather than guessing.
Our Process, Step by Step
- 1
You call and a person answers. A live person picks up at (424) 337-6939, 24/7, including weekends and holidays. No call tree, no voicemail loop. You describe the project and we schedule a site visit.
- 2
We visit, measure, and listen. Isaac Pruett or a senior project lead comes to your Torrance home, takes photos and measurements, and asks about how the space is actually used. We also test the basics: moisture readings, outlet load, joist spacing.
- 3
You get a written, line-item price. Within days of the visit, you receive a written quote with every line item broken out. No verbal estimate that grows, no allowances that balloon. The price you see is the price you approve.
- 4
We schedule, pull permits, and build. Once approved, we pull permits, order materials, and set a start date. Your crew’s names and photos are sent to you before day one. Work proceeds on schedule with weekly updates by phone.
- 5
Final walkthrough and written guarantee. Before we consider a job done, we walk the project with you and fix anything that is not right. You receive your written guarantee, your permit sign-offs, and your project photo file.
How Much Does General Contractor Cost in Torrance?
A typical kitchen remodel in Torrance runs $14,000 – $45,000, with cabinet installation adding $4,000 – $13,000 depending on the line and layout. Bathroom remodels sit between $9,000 – $28,000, with smaller baths at $5,000 – $12,000. For additions, expect $45,000 – $130,000, and for a full ADU, $90,000 – $220,000. These ranges reflect Torrance’s labor market, permit fees, and the cost of hauling materials through South Bay traffic.
What drives the price: scope of demolition, load-bearing wall changes, plumbing and electrical reroutes, material grade, and whether you stay in the home during the work. What protects you from overpaying: a written price that does not change unless you change the scope, and a contractor who shows you the line items. Our free estimate includes a full walkthrough, measurements, and a written quote. No deposit required to see the number. Call (424) 337-6939 to schedule yours.
