We work Diamond Bar’s 91765 zip code regularly, and we know the Building & Safety desk well enough to plan around it. Call us at (877) 610-1318 and we’ll walk you through what your exact kitchen will cost before you sign anything.
Why Barrett & Sons Construction Is Diamond Bar’s Preferred Kitchen Remodeling Company
Tom Barrett founded this company in 1998, and his sons run the crews that work Diamond Bar kitchens. That’s not a marketing line. When we say the owner’s name is on the truck, we mean Tom’s actual name, his address, and his license number are all published and verifiable. Look them up before you sign. Ask anyone on your street, or look up the license number yourself.
Diamond Bar customers call us because the last contractor told them permits were optional. They weren’t. We pull permits on every eligible job, and we make the inspector our friend, not our obstacle. The permit inspector works for you, not for me. That’s why I like him. Every scope change, every allowance, every price adjustment arrives as a written change order before a single nail moves. Scope in writing, allowances in writing, change orders in writing.
Calls to (877) 610-1318 are answered by a live person, any hour. Not a voicemail box, not an out-of-state call center. And every completed kitchen is backed by the 90-Day Done Right Promise, written on the contract: if something isn’t right, Tom comes back and makes it right, one call.
Our Kitchen Remodeling Services in Diamond Bar
Full Kitchen Remodeling
A full kitchen remodel in Diamond Bar means gutting the room to studs on many of these 1960s through 1980s tract homes. We handle it all, from the first sledgehammer to the final walkthrough with the inspector. On hillside lots off Grand Avenue and Diamond Bar Boulevard, we coordinate the geotechnical review that the city often requires when we touch a load-bearing wall or foundation. Our Kitchen Remodeling team has done enough of these to schedule the engineering early so it doesn’t stall your job in week four.

Cabinets & Countertops
We install KraftMaid cabinetry and Cambria quartz, plus granite and solid-surface options, across Diamond Bar kitchens. Cabinet installation alone runs $4,000 to $13,000 depending on linear footage and whether you go stock, semi-custom, or full custom. Countertop installation runs $2,000 to $6,500. We don’t install mystery brands off a van. You can look up every material we quote.

Backsplash, Tile & Flooring
Backsplash installation in Diamond Bar kitchens runs $800 to $2,500 for standard ceramic or porcelain, moving up from there with hand-cut stone or full-height slab. Floor tile gets more complicated on these sloping lots. We check for subfloor deflection before we set tile, because the expansive clay under many Diamond Bar slabs moves seasonally. Setting tile over a moving slab is how you get cracks six months after the final check. We fix the substrate first.

Kitchen Design & Layout
Diamond Bar’s split-level floor plans create awkward traffic patterns that a flat-lot kitchen never deals with. We work through the layout with you before the first wall opens. Island placement, plumbing reroutes, and sightlines all change when the kitchen sits half a story above the family room. We’ve redesigned dozens of these, and we’ll show you what works in your specific floor plan, not a generic magazine spread.

Fast turnaround for Diamond Bar customers comes from keeping common hardware and components in local supply, not waiting on a distribution center two states away.
Common Kitchen Remodeling Problems We See in Diamond Bar Homes
- Hillside permit triggers. Opening a load-bearing wall on a sloping lot without checking the city’s slope review can turn a simple kitchen remodel into a stop-work order and a rushed geotechnical report. We file that check early, before demo day, so the job doesn’t stall.
- Expansive clay under the slab. The San Jose Hills clay swells and contracts seasonally. If the slab has moved for 50 years, new cabinets and countertops will sit on a surface that’s still moving. We address drainage and sub-slab conditions before anything else goes in.
- Fire-zone compliance on windows and vents. Large portions of upper Diamond Bar fall within LA County’s Very High Fire Hazard Severity Zone. A kitchen window replacement there needs Chapter 7A-rated glass and ember-resistant vents to pass inspection. We specify those from the start.
- Aging cast-iron drain lines. Original 40-to-60-year-old drain lines under these tract homes are reaching failure. Opening a kitchen for remodel is the right time to inspect and replace what’s underneath before it leaks into a brand-new cabinet run.

FAQs - Kitchen Remodeling in Diamond Bar
Often yes, if that wall is load-bearing and your lot slopes enough that the city’s Building & Safety reviews it as a hillside structural change. Removing the wall without that review can trigger a stop-work order. We file the check early and tell you in the first week whether your project will need it. Call (877) 610-1318 with your address and we’ll give you a straight answer.
Homes in LA County’s Very High Fire Hazard Severity Zone, which covers much of upper Diamond Bar, need Chapter 7A-compliant glazing and ember-resistant vents when windows are replaced as part of a remodel. We specify those assemblies from day one, so the inspection passes and your insurance company has no grounds to deny a future claim. Call for a free estimate and we’ll confirm whether your address falls in the zone.
A finaled permit creates a paper trail that your remodel met code at the time of inspection. If a fire, water leak, or structural failure happens later, your insurer has a record that the work was done per code. Unpermitted work, especially in fire hazard zones, is a common reason claims get denied. We pull permits on every eligible job and hand you the signed inspection card at the end.
Line items for the geotechnical report, if your lot triggers one. Chapter 7A-rated windows and ember-resistant vents if you’re in the fire zone. Engineering for any load-bearing wall removal. Drain line inspection and sub-slab drainage work on expansive clay. If the low bid doesn’t mention those, it isn’t cheaper. It just hasn’t priced the job yet. Call (877) 610-1318 for a written quote that includes all of it.
Your slab or post-and-pad foundation has likely settled or shifted with the expansive clay that runs through the San Jose Hills. That movement gets worse with seasonal moisture changes, and new cabinets and countertops will telegraph every dip. We assess the foundation and subfloor before we set anything on top of it. Fixing the cause first is cheaper than re-leveling cabinets later.
