Why Elmstead Remodeling Pasadena Is Altadena’s Preferred General Contractor Company
We have been working in Altadena long enough to know the difference between a 1930s Spanish Colonial Revival on New York Drive and a 1960s track ranch on Altadena Drive. That distinction matters when you are planning a remodel or a post-fire rebuild. The foundation types differ. The sewer laterals are a different vintage. The roof pitch changes. Our crews have worked on Washington Boulevard, Fair Oaks Avenue, and the winding hillside streets above Mendocino Lane, so we come prepared for the actual conditions on your lot.
Customers in Altadena keep calling us back because we do what we say we will. We hand you a written line-item price before any work begins, not a rough range that drifts upward mid-project. We take a photo of the clean-up before the crew leaves for the day. And when a client near Farnsworth Park asked us to work around a newborn’s nap schedule, we swapped to quiet-cutting tools during the afternoons and rolled the delivery schedule accordingly. That is how we run every job here.
Hire a General Contractor in Altadena

Hire a General Contractor in Altadena when the work touches structure, load-bearing walls, roofing, foundation, or anything behind the drywall. If you are in the post-Eaton rebuild process, or if you own one of the many homes here with original galvanized plumbing and clay sewer laterals, a licensed general contractor from General Contractor is the single point of contact who pulls permits, schedules inspections, coordinates subs, and keeps the job moving without you chasing calls.
A typical home addition in Altadena runs $45,000 to $130,000. The range difference comes down to hillside grading, foundation repair, WUI fire-hardening requirements, and whether the existing structure needs seismic retrofitting before framing starts.
Permits and WUI Review
Altadena sits in Los Angeles County’s wildland-urban interface zone. After the Eaton Fire, LA County tightened the rules on defensible space, ignition-resistant construction, and hillside grading. Skipping the WUI special inspection early can trigger a stop-work order and a redesign fee. We sequence every Altadena project so the county review happens before framing, not after.
The Written Price Promise
Every project starts with a written price, printed and itemized, before a single tool enters your home. That price does not change when the crew finds original galvanized supply lines or a cracked clay lateral under the slab. If hidden damage expands the scope, we talk to you first, in plain language, with a new written number before we continue. No surprises, no vague change orders.
General Contractor Services in Altadena
General Contractor Services in Altadena cover the full range of General Contractor in Altadena work families here call us for: kitchen and bathroom remodels, whole-home renovations, room additions, garage conversions, ADU construction, and full post-fire rebuilds. We also handle the structural and systems work that comes up once walls are opened – re-piping to PEX, trenchless sewer lining, foundation repair, and seismic retrofitting on older homes.
Our Kitchen Remodeling - Altadena services start around $14,000 for a galley refresh in a smaller bungalow and go up to $45,000 for a full layout change with custom cabinets from KraftMaid or Wellborn and a Cambria or Silestone countertop. Bathroom remodels run $9,000 to $28,000 depending on whether the scope is a cosmetic update or a full gut with new waterproofing, a Schluter system, and a Kohler or Moen fixture set.
Fire-Hardening and Rebuild Work
Post-Eaton reconstruction in Altadena is not the same as a remodel in Pasadena. We work through the LA County WUI checklist on every hillside rebuild: ignition-resistant siding and decking, ember-resistant venting, tempered glass on the wildland side, and defensible-space grading. James Hardie fiber cement and GAF roofing are standard references on these jobs because their fire ratings hold up under county review.

Older Home Systems Work
Many Altadena homes built between the 1920s and the 1960s still have original clay sewer lines and galvanized pipes. Hard water and expansive soils crack and corrode both. Before we close walls on any remodel, we camera-scope the lateral and check supply lines. If roots have invaded the clay pipe, we quote a trenchless liner. If the galvanized is failing, we re-pipe to PEX and sign it off before backfill.

AfterCommon General Contractor Problems We See in Altadena Homes
- Hillside staging and material delivery. Concrete trucks and long trailer deliveries get stuck on winding streets like those above Lake Avenue if the access plan is not worked out in advance. We pre-plan the drop zone, sometimes using a roll-off-protected driveway apron or a neighbor’s pre-approved parking easement.
- Skipped WUI review before framing. We have been called in after another contractor framed walls and hit a county stop-work order for missing the wildland-urban interface special inspection. That mistake costs weeks and a redesign. We file early.
- Original clay sewer laterals under the slab. A kitchen or bath remodel can pass rough-in and then fail on backflow or root intrusion within a year because no one camera-scoped the lateral. We scope before we close.
- Expansive soil cracking foundations. Altadena’s clay-rich soils shrink and swell with moisture changes, which is why so many 1920s-to-1960s homes here show foundation cracks. Adding a second story on a compromised foundation is a structural risk, so we evaluate the footing before any second-story framing begins.
Pricing for General Contractor in Altadena, CA

Altadena pricing reflects the reality of the hillside. Access matters more than many quotes admit. A home addition ranges from $45,000 to $130,000, and the difference often comes down to whether a concrete truck can reach the pour, whether the county requires a geotech report for grading, and how much seismic retrofit the existing structure needs. Here is a line-item look at the three most common project types.
| Project | Price Range |
|---|---|
| Home Addition | $45,000 – $130,000 |
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |

FAQs About General Contractor in Altadena

Yes. A post-Eaton rebuild in Altadena requires LA County WUI review, which now includes defensible-space, ignition-resistant construction, and often hillside grading approval beyond what Pasadena requires just a mile south. We handle the sequencing so the county review happens before framing, and we pull all permits and pass inspections on your behalf. Call (626) 714-2992 for a free walkthrough of your lot’s specific requirements.
We file a staging plan before we start. On a tight Altadena lot off Lake Avenue, we staged materials on a roll-off-protected driveway apron and used a neighbor’s pre-approved parking easement for our crew, with their written agreement in hand. We also file a party-wall notice when the work touches a shared wall or boundary, so neighbors know what is coming and when. This is part of the written price; it is not an add-on.
LA County restricts construction noise to 7 a.m. to 6 p.m. on weekdays. We work within that window, and we respect quieter hours by scheduling the louder cutting and demolition during mid-morning and early afternoon. If you have a baby or a night-shift worker in the house, we coordinate around that too. Call (626) 714-2992 and we will note your quiet hours in the project plan.
Altadena’s clay-rich soils shrink and swell with moisture changes, which puts stress on foundations built between the 1920s and 1960s. If the crack is structural, yes, you need to address it before a second story goes up. We evaluate the footing, check for seismic retrofitting needs, and quote the fix as a line item before any vertical framing begins. Ignoring it risks a failed inspection and a compromise in the structural load path.
You get a written change order with a new price before we continue. That is how the Cedarwell Care Promise works. If we open a wall and find galvanized pipes that need replacing or a clay lateral that needs a trenchless liner, we show you the invoice-level cost, explain the work, and get your sign-off. The original written price is never changed silently. Call (626) 714-2992 to talk through how that protections applies to your project.
