What Makes the Best Construction Companies San Bernardino County?
Understanding what distinguishes excellent construction companies from mediocre or problematic ones helps you make informed decisions.
Valid California Contractor’s License
Why It Matters: California law requires contractors performing work over $500 to hold valid contractor’s licenses issued by the Contractors State License Board (CSLB). Licensed contractors have met minimum experience, examination, and financial requirements.
•License status (active, inactive, suspended)
•License classification (B – General Building Contractor is most common for home remodeling)
•Expiration date
•Bond status
•Workers’ compensation insurance
•Complaint history
WM Construction: We are licensed by the California State License Board—License #1075983. You can check it online. We maintain active licensing, bonding, and insurance at all times.
Proven Track Record with Verifiable Experience
Why It Matters: Experience indicates a company has successfully completed projects similar to yours and navigated challenges that arise during construction.
What to Look For:
•Years in business (10+ years demonstrates stability)
•Number of completed projects (100+ indicates significant experience)
•Specialization in your project type (kitchen remodeling, ADUs, additions)
•Portfolio of completed work with before-and-after photos
WM Construction: We’ve been remodeling homes in Rancho Cucamonga and Ontario since 2014—more than 10 years of real work, one home at a time. Every project we finish comes with a signed client form—we’ve completed 127+ home remodels since 2014.
Transparent Communication and Process
Why It Matters: Construction projects involve dozens of decisions, potential challenges, and coordination. Clear communication prevents misunderstandings, manages expectations, and ensures you’re never left wondering what’s happening.
What to Look For:
•Detailed written estimates explaining what’s included and what’s extra
•Clear timeline with milestones
•Regular progress updates (weekly at minimum)
•Responsive to questions and concerns
•Written contracts specifying every detail
WM Construction: We provide weekly photo and video updates so you always know what’s happening. You won’t be left wondering about progress. Every project includes a written contract with every detail specified—from start date to final inspection. No hidden changes, no surprises.
Quality Workmanship with Guarantees
Why It Matters: Quality workmanship ensures your investment lasts and performs as expected. Guarantees demonstrate the company stands behind their work.
What to Look For:
•Warranties on workmanship (typically 1-2 years minimum)
•Use of quality materials from reputable suppliers
•Attention to detail in finishing work
•Willingness to address any issues that arise
WM Construction: We guarantee all our work. We don’t say “it’s done” until you say it’s right. If you see anything that’s not perfect, we fix it. We won’t finish until you’re happy.
Design Capabilities and Visualization
Why It Matters: Many homeowners struggle to visualize how finished projects will look. Design capabilities and visualization tools help you see your project before construction begins, reducing anxiety and ensuring the result matches your vision.
What to Look For:
•In-house design services or partnerships with designers
•3D renderings or computer-aided design
•Willingness to revise designs based on your feedback
•Portfolio demonstrating design sophistication
WM Construction: We’re the only company in Rancho Cucamonga and Ontario that offers a free 3D design before you pay a dime. Within a few days of our initial meeting, we show you a 3D rendering of your project. You’ll see exactly how it will look—the layout, the materials, the finishes. If you want changes, we make them. We don’t start building until you love the design.
Fair Pricing with Detailed Estimates
Why It Matters: Transparent pricing helps you budget appropriately and avoid surprise costs. Detailed estimates show exactly what you’re paying for.
What to Look For:
•Itemized estimates breaking down materials, labor, and other costs
•Clear explanation of what’s included and what’s extra
•Reasonable payment schedule (avoid contractors demanding large upfront payments)
•Written change order process for modifications
WM Construction: We provide detailed written estimates explaining every cost. We discuss your budget upfront and design solutions that work within your financial parameters. Our payment schedule is fair and tied to project milestones—never large upfront deposits.
Proper Insurance and Bonding
Why It Matters: Insurance protects you from liability if workers are injured on your property or if property damage occurs. Bonding provides financial recourse if the contractor fails to complete work or violates contract terms.
What to Look For:
•General liability insurance (minimum $1-2 million)
•Workers’ compensation insurance
•Contractor’s bond (required for licensed contractors in California)
•Willingness to provide certificates of insurance
WM Construction: We maintain full general liability insurance, workers’ compensation insurance, and contractor’s bond as required by California law. We provide certificates of insurance upon request.
Red Flags: Warning Signs of Problem Construction Companies
Recognizing warning signs helps you avoid problematic contractors before committing to projects.
No Valid License or Refuses to Provide License Number
The Red Flag: Contractor claims to be licensed but refuses to provide license number, or provides invalid/expired license number.
Why It’s Dangerous: Unlicensed contractors:
•Lack legal accountability
•May not carry insurance
•Often lack proper training and experience
•Leave you with no recourse if problems arise
•May violate building codes
What to Do: Always verify license numbers at www.cslb.ca.gov before hiring. Never hire unlicensed contractors.
Demands Large Upfront Payments
The Red Flag: Contractor demands 50% or more upfront before starting work.
Why It’s Dangerous:
•Reduces contractor motivation to complete work
•Leaves you vulnerable if contractor abandons project
•Provides no leverage if quality is poor
•Common tactic of scam artists
What to Do: Reputable contractors follow industry-standard payment schedules (10-20% down, progress payments tied to milestones, final payment upon completion). Avoid contractors demanding large upfront payments.
No Written Contract or Vague Contracts
The Red Flag: Contractor proceeds with verbal agreements or provides contracts lacking specific details about scope, materials, timeline, or costs.
Why It’s Dangerous:
•No legal protection if disputes arise
•Scope of work is unclear
•Timeline expectations differ
•Payment terms are ambiguous
•Change orders become contentious
What to Do: Insist on detailed written contracts specifying scope, materials, timeline, payment schedule, and warranty terms. Never proceed without signed contracts.
Poor Communication or Unresponsive
The Red Flag: Contractor is difficult to reach, doesn’t return calls or emails promptly, or provides vague answers to questions.
Why It’s Dangerous:
•Communication problems before hiring predict worse problems during construction
•Indicates lack of professionalism
•Suggests contractor is juggling too many projects
•You’ll be left wondering what’s happening
What to Do: Choose contractors who communicate clearly, respond promptly, and provide detailed answers. Poor communication before hiring won’t improve after you’ve paid.
No References or Refuses to Provide References
The Red Flag: Contractor claims to have completed many projects but can’t or won’t provide references.
Why It’s Dangerous:
•May indicate dissatisfied customers
•Suggests lack of completed projects
•Prevents you from verifying quality and professionalism
What to Do: Request references from recent projects similar to yours. Contact references and ask specific questions about quality, communication, timeline, and overall satisfaction.
Pressure Tactics or “Today Only” Deals
The Red Flag: Contractor pressures you to sign immediately, claims special pricing only available today, or discourages you from getting multiple quotes.
Why It’s Dangerous:
•Legitimate contractors don’t use high-pressure sales tactics
•Suggests contractor is desperate for work (why?)
•Prevents you from making informed decisions
•Often indicates scam operations
What to Do: Take time to evaluate options, get multiple quotes, and make informed decisions. Avoid contractors using pressure tactics.
