Trust Cornejos Builders for Home Improvements in Bellflower, CA

Most contractors will tell you they can handle your home improvement project. Then they disappear for days, leave your house a mess, and suddenly the quote you got has magically doubled. We’ve heard these stories more times than we can count from homeowners around Bellflower.

That’s exactly why we built Cornejos Builders the way we did. We send you daily updates, which may seem simple, but most contractors can’t manage. We give you a five-year warranty on our workmanship because we plan to still be here in the next decade and the one after that.

And when we quote you a price, that’s what you pay. No surprise fees or other nonsense halfway through.

Home improvements can mean many things. New roofing that actually keeps the rain out. Interior remodeling that opens up your space. Exterior painting that makes your house look like you care about it again. New windows, new doors, a deck where you can finally have people over. We handle it all and do it right the first time.

We couldn’t have asked for a better contractor to work with than Alex. We were needing our home remodeled in a very short window of time and Alex and his crew were always on schedule and in touch with us throughout the whole remodel. We would definitely use them again.

What Home Improvements Actually Cost in Bellflower, CA

Here’s the honest truth: home improvement costs depend entirely on what you’re trying to do. A simple deck repair might run you around $5,000. A complete interior remodel where we gut the place and start over? That can climb past $200,000. Most of our projects fall between $20,000 and $80,000, and they typically take 1 to 4 months to complete.

These numbers come from actual projects we’ve completed around Bellflower. Your project will have its own price based on what needs to be done. Send us the details, and we’ll give you a real number you can work with.

What affects the final cost?

Scope of Work: Obviously, replacing a few windows costs less than remodeling your entire kitchen. The more work you need done, the higher the investment. If you're combining multiple projects, like new siding plus window replacements, expect the price to reflect that added complexity.
Materials You Choose: Granite countertops cost more than laminate. Luxury vinyl flooring runs cheaper than hardwood. The materials you pick make a huge difference in the final bill. We can work within your budget and still get you durable, quality materials that make sense for your home.
Size of the Space: A small bathroom remodel costs less than a primary suite overhaul. Painting two rooms differs from painting your entire house. So, square footage matters. The bigger the space, the more labor, materials, and time needed.
Structural Changes: Knocking down walls to create an open floor plan? Rerouting plumbing or electrical systems? These structural changes add cost because they require permits, inspections, and specialized work.
Current Condition: If we open up your walls and find old wiring that needs replacing, or discover water damage that has to be fixed first, that affects the timeline and budget. We do our best to anticipate issues during the estimate, but sometimes you don't know what you're dealing with until you start.

Keeping Your Project on Budget and on Schedule

We know what you’re thinking. Construction projects always go over budget and take twice as long as promised, right? We’ve heard that worry before, and honestly, sometimes it’s deserved, given how this industry operates.

Let’s say you invest $50,000 in a complete home exterior refresh. New siding, new paint, new front door, updated fixtures. You’ll enjoy that improvement every single day for at least the next 15 years. Break it down, and you’re spending about $9 per day to love coming home to your house. That’s less than lunch. And the best part? Your home’s value goes up, so you’re not just spending money. You’re moving it into an asset you actually use.

Construction feels invasive, we’ll admit that. Having people in your house, dealing with noise and dust, wondering when it’ll all be done. But we actually know how long projects take because we’ve done hundreds of them. We give you realistic timelines, we stick to them (barring any genuine surprises like discovering old termite damage), and we clean up at the end of every day.

Common Questions About Home Improvements in Bellflower, CA

How long does a typical home improvement project take?

Most of our projects run one to four months, depending on what you’re doing. A bathroom remodel might take three weeks. A full kitchen plus flooring throughout the house? Closer to three months. Weather can sometimes delay exterior work, and occasionally we find issues once we open up walls, but those delays are rare, and we communicate them immediately when they happen.

Do I need permits for home improvement work in Bellflower?

Depends on the work. Painting your house? No permit needed. Knocking down a wall, adding a bathroom, replacing your roof? Yes, you need permits. The good news is we handle all of that for you. We pull the permits, schedule the inspections, and deal with the city. That’s part of what you’re paying us to do.

Can you work around my schedule if I work from home?

Absolutely. We’ve done plenty of projects where homeowners are working from home, especially these days. We coordinate with you on which areas we’re working in and when. If you need us to avoid making noise during certain hours, or to stay out of specific rooms on days you have important calls, just tell us. We’ll make it work.

What if I want to make changes midway through the project?

Changes happen, and we can usually accommodate them. The key is telling us as early as possible. Small tweaks like swapping one paint color for another? Easy. Deciding you want a kitchen island when we’re already halfway done? That’s trickier. We’ll always talk through what a change means before we implement it. Just keep in mind that earlier is better when it comes to adjustments.
