AfterFast, Reliable General Contractor Across Pasadena
Hiring a General Contractor in Pasadena means finding someone who understands what this city actually demands from a remodel. Pasadena isn’t a generic Los Angeles suburb. It’s a city where a 1912 Craftsman bungalow in Bungalow Heaven sits under one set of rules while a hillside home in the Annandale area answers to another, and sometimes the same project has to satisfy both. We’re Penhallow Remodeling, and we work inside those rules every week. Call us at (936) 259-2607 for a free estimate on kitchen remodeling, bathroom remodeling, or a whole-home remodel in Pasadena, and you’ll get a written price before any work starts.
Why Penhallow Remodeling Is Pasadena’s Preferred General Contractor Company
Pasadena homeowners hire us because we put the number in writing before we pull a single cabinet, and we stand behind the work with a 365-Day Done Right Promise. If something isn’t done right, we come back and make it right, at no charge. That promise is in writing on every project we take on in Pasadena.
Trevor Nash leads our team, and he grew up on the idea that a contractor should answer the phone, show up when they said they would, and leave the job site cleaner than they found it. Our technicians are background-checked and arrive in uniform, so you know exactly who’s walking through your door. A live person answers our phone 24/7, not a voicemail maze. When you call from Pasadena, you talk to a person.
Every Pasadena project runs on written pricing. Not an estimate range. Not a verbal ballpark. A written number you can hold us to. We source materials from recognized trade brands like Cambria quartz, KraftMaid cabinetry, and James Hardie siding, because the products behind the guarantee need to be as solid as the promise itself.
General Contractor Services in Pasadena
General Contractor Services in Pasadena cover the full scope of a remodel: demolition, structural work, plumbing rough-in, electrical, drywall, millwork, and finishes. A Pasadena homeowner calls us when a kitchen feels cramped, a bathroom is dated, or a house needs to grow. The work involves coordinating trades, pulling permits, scheduling inspections, and keeping the job moving while the homeowner lives their life. Kitchen remodels in Pasadena typically run $14,000 to $45,000. Bathroom remodels run $9,000 to $28,000. Home additions run $45,000 to $130,000.
Kitchen Remodel Coordination
We manage the sequence: demo, plumbing and electrical rough, inspection, drywall, cabinet install, countertop template, countertop fabrication, final fixtures. For Pasadena kitchens, cabinet selection drives the schedule more than anything else. KraftMaid and Wellborn cabinetry have lead times that range from three to nine weeks depending on the line, and we order them the week the contract is signed. Cambria quartz countertops are templated only after the cabinets are set, and fabrication typically runs two to three weeks. Every one of these dates is written into your project schedule.
Bathroom Remodel Execution
Pasadena bathrooms in older homes often hide surprises behind the tile: rotted subfloor from a leaking tub, galvanized supply lines, or original plaster that crumbles when you open the wall. We open the wall knowing we might find it, and we write the budget knowing it might happen. When we find a problem, we show you the issue, explain the repair, and put the change in writing before we proceed. Walk-in shower installations run $4,500 to $12,000. Tub-to-shower conversions run $3,500 to $10,000.

Construction Company in Pasadena
A Construction Company working in Pasadena carries a different load than one working in, say, Alhambra. Pasadena’s building department enforces the California Building Code, but it also enforces local historic preservation standards and wildland-urban interface fire codes that change which materials you can actually buy and install. Construction Company work here means structural headers, shear walls, foundation bolting, and fire-rated assemblies. ADU construction in Pasadena runs $90,000 to $220,000. Window replacement runs $4,500 to $15,000. Roof replacement runs $8,000 to $20,000.
Structural and Seismic Upgrades
Pasadena’s pre-1940 housing stock was built before modern seismic code. Stem-wall foundations lack the bolting now required for major remodels. Unreinforced masonry chimneys crack in earthquakes. We add foundation bolts, plywood shear panels, and steel hold-downs where the engineer specifies them, and those items go into your written scope before we start.
Addition and ADU Builds
Home additions and ADUs in Pasadena face the city’s planning department just as much as the building department. Setbacks, lot coverage, and design review all shape what can be built. We coordinate the drawings, the planning submittal, and the build, so you don’t get a nasty surprise halfway through. Rooms additions and garage conversions commonly fall between $45,000 and $130,000 depending on square footage and foundation work.
We also work with prefabricated accessory dwelling unit brands like Abodu and Dvele where the site and zoning allow it, and we handle the site work, utility connections, and foundation that those units require. For concrete work, we specify Sakrete products because we know how they cure in Pasadena’s summer heat.
Trusted Brands We Service in Pasadena
We install and service work built around materials that hold up in Pasadena’s climate. Cambria, Silestone, and Caesarstone countertops carry their own manufacturer warranties alongside ours. Kohler and Moen fixtures come with decades of parts availability. James Hardie siding is engineered for fire resistance, which matters in the foothill zone. For Pasadena homeowners, we stock common replacement parts locally and coordinate directly with suppliers, so the countertop you ordered doesn’t sit in a warehouse while your kitchen sits torn apart. When we use a brand, we stock its local service path too. Abodu and Cover prefab structures work well for Pasadena backyards, and we handle the site prep and utility runs those projects need.
Common General Contractor Problems We See in Pasadena Homes
- Knob-and-tube wiring buried in historic plaster walls. We find it behind original lath in Bungalow Heaven and Madison Heights homes. Rewiring is disruptive, but leaving live and abandoned circuits inside a wall you’re about to close up is a code violation and a fire risk, so we put the rewire in the written scope before demo day.
- HPOZ design-review delays that slip the schedule. In Bungalow Heaven, exterior alterations require a Certificate of Appropriateness before a permit is issued. Stock vinyl-frame windows or fiber-cement lap siding will be denied. Wood or aluminum profiles that replicate the original 1910s divided-light patterns pass, and they add weeks of lead time.
- Chapter 7A fire-code materials missing from the bid. Homes near the San Gabriel foothills fall under California’s Very High Fire Hazard Severity Zone. Ember-resistant vents, Class A roofing, and ignition-resistant wall assemblies are required, and a bid that omits them will fail inspection and trigger rework costs.
- Non-seismic stem-wall foundations on pre-1940 homes. A kitchen or bathroom remodel that opens walls on a 1920s bungalow often requires foundation bolting before the drywall goes back up. The building department wants it, and the structural engineer specifies it.
Pricing for General Contractor in Pasadena, CA
Here’s the honest version. Labor is not what drives cost in Pasadena. Materials and regulatory lead time do. Custom millwork for an HPOZ-adjacent job can take eight to twelve weeks. Chapter 7A roofing and venting materials carry a premium over standard stock. Permit and design-review fees run higher here than in unincorporated Los Angeles County. We give you a written price before any work starts, and that price holds. No change orders on our own mistakes. No surprises when the invoice comes. Here’s what Pasadena projects look like:
| Project | Typical Pasadena Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Window Replacement | $4,500 – $15,000 |
| Roof Replacement | $8,000 – $20,000 |

FAQs About General Contractor in Pasadena
Any exterior alteration in a Pasadena Historic Preservation Overlay Zone requires a Certificate of Appropriateness from the Design and Historic Preservation section before a building permit is issued. This applies to windows, doors, siding, roofing, and even paint color in some cases. Interior work that doesn’t change the building envelope typically doesn’t need COA review, but structural changes still need a standard building permit. Call (936) 259-2607 and we’ll tell you exactly which approvals your specific project needs.
If your addition sits in a Very High Fire Hazard Severity Zone in the foothills, the new structure must meet Chapter 7A ignition-resistant construction standards. That means Class A roofing, ember-resistant vents, multi-pane tempered glass in certain locations, and non-combustible exterior cladding on walls and eaves. A bid that doesn’t include these materials will be corrected at the building department and the cost will land on you. Call (936) 259-2607 to get a written scope that includes fire-code compliance from day one.
Because the HPOZ won’t let you use stock windows. Bungalow Heaven and Madison Heights homes require wood or aluminum profiles that replicate the original 1910s divided-light patterns, and those are custom-milled or special-ordered. The design review alone adds two to six weeks, and fabrication adds another six to ten. Vinyl windows would be faster and cheaper, but they’ll be denied. Call (936) 259-2607 and we’ll give you a realistic timeline before you’re committed.
Every scope should list specific materials by brand and product line, permit and design-review fees, the construction schedule with real dates, and an explicit line for unforeseen structural or electrical conditions found during demo. If the scope doesn’t name the cabinet line, the countertop material, and the roofing class, it’s not specific enough. We write all of that into every Pasadena contract, in plain language, before any work starts. Call (936) 259-2607 to see what a real written scope looks like.
We stop, show you the wire, explain that leaving it live inside a closed wall is a code violation and a fire hazard, and write the rewire as a change order with a fixed price before we proceed. Knob-and-tube is common in Pasadena’s pre-1930 housing stock, and an experienced General Contractor in Pasadena expects to find it. The key is that the change order is written, not verbal, and the price doesn’t balloon. Call (936) 259-2607 and ask us how we handle exactly this scenario.
One Street, Two Rulebooks
Pasadena is the rare city where a general contractor can face both a Historic Preservation Overlay Zone Certificate of Appropriateness review and California Very High Fire Hazard Severity Zone Chapter 7A ignition-resistant construction requirements on the same street. No neighboring city does this. Not Arcadia. Not Monrovia. Not Temple City. A remodel on one block of Pasadena can require custom wood divided-light windows to satisfy the HPOZ, and then the rear addition at the same address needs ember-resistant vents and Class A roofing because it sits in the fire zone. Getting this wrong means a permit denied at design review and a failed inspection months later. Getting it right means planning both rulebooks into the schedule from the first walkthrough.
We were gutting a 1918 Craftsman in Bungalow Heaven and found original knob-and-tube wiring buried inside historic plaster walls, a non-seismic stem-wall foundation, and an unreinforced masonry chimney. The HPOZ review required custom wood divided-light windows matching the original 1910s pattern, and because the rear addition extended into the Very High Fire Hazard Severity Zone, we had to specify ember-resistant vents and Class A roofing. Long-lead custom millwork and Chapter 7A materials, not labor, drove the 22-week schedule. The homeowner got the price in writing before we ordered a single window. That’s how this works in Pasadena.
