AfterConstruction Services in Altadena, CA
Altadena sits right where the San Gabriel Mountains drop into the foothills, and the homes here reflect that geography: 1920s craftsman bungalows, Spanish Colonial Revivals, mid-century ranches, and now, after January 2025, thousands of empty lots rebuilding from scratch. If you’re sorting out where to start, you’re not alone. We answer the phone at (877) 610-1318, we know the county permit process backwards, and we’ll tell you straight what your project needs and what it doesn’t.

Why Altadena Homeowners Choose Barrett & Sons Construction
We’re Tom Barrett and his sons. That’s who shows up. No franchise, no rotating cast of subcontractors you’ll never see again, no out-of-state call center. We’ve been owner-operated since 1998, and when we say we’ll be there Thursday morning, the truck with our name on the door is in your driveway Thursday morning. Homeowners in Upper Hastings Ranch and The Meadows call us because they want someone who knows what a pre-fire lot survey looks like, who has pulled LA County permits dozens of times, and who writes every change order on paper before a hammer moves. We carry the brands you can verify: KraftMaid and Cambria for kitchens, GAF for roofs, Andersen for windows. And every job ends with our 90-Day Done Right Promise written into the contract. If something isn’t right, one call brings Tom back.

Roofing
Post-fire code now requires Class A fire-rated roofing throughout Altadena’s Very High Fire Hazard Severity Zone, and LA County inspectors check it closely. For Altadena Roofing, we install GAF systems with ember-resistant vents and bring the paperwork for every inspection.

Windows & Doors
Windows & Doors in Altadena must meet WUI glazing requirements in the hillside zones, which changes what you can buy and what gets approved. We source Andersen and Marvin units sized for the openings you actually have, not the ones the salesman wishes you had.
Learn more about our home services.
Fence Installation
We build redwood and composite fences on post-fire lots all over 91001, and we handle the property-line verification before we dig. In the burn zone, that survey step matters more than ever with so many lot markers gone.

Driveway & Pavers
Alluvial-fan soils shift, which shows up as cracked driveways and sunken walkways across Altadena. We re-grade, compact, and use Belgard and Techo-Bloc pavers with proper drainage so the repair holds.

Home Additions & ADU
If your lot is one of the thousands affected by the Eaton Fire, rebuilding gives you a rare chance to add an ADU under current county allowances while you’re already in the permit queue. We manage the full scope from foundation to final inspection, permits included.

Why Altadena’s Climate & Housing Affect Construction
The Eaton Fire didn’t just destroy homes; it changed the ground beneath them. Hydrophobic soil on the slopes above Altadena now repels water instead of absorbing it, which means every heavy rain carries debris-flow risk onto the alluvial fans below. Any foundation or site work has to account for that, plus the retention walls left compromised by fire-suppression water soaking into already-shifting soil. Most rebuilds we’re quoting in 91001 start with geotechnical evaluation before a permit gets approved. And because Altadena is unincorporated, all of it runs through LA County’s Department of Public Works, not a city building desk. That’s a different set of forms, timelines, and inspection sequences than Pasadena uses right next door. We pull permits for every eligible job and we sit through every inspection, because the inspector works for you, not for us. That’s why we like him.
Pricing for Construction in Altadena
Pricing follows the scope and the lot. A full kitchen remodel in Altadena often lands between $55,000 and $120,000. Bathrooms run $28,000 to $60,000. Roof replacements on a 1,800 square foot single-story run $14,000 to $24,000 depending on pitch and fire-code upgrades. ADUs start around $180,000 for a basic 400-square-foot unit and climb from there. Driveway pavers run $18 to $32 per square foot installed. Every estimate is free, every price change comes as a written change order before work proceeds, and we honor our standing discounts: $40 off any repair over $200, a free second opinion on any written estimate, no trip charge inside Los Angeles County, and a permanent 10% senior and veteran discount.

FAQs About Construction in Altadena
Yes. Every rebuild and most substantial remodels in Altadena require permits through LA County’s Department of Public Works, and because Altadena sits in a Very High Fire Hazard Severity Zone, the plans must also meet WUI codes for fire-resistant materials, ember-resistant vents, and Class A roofing. We pull every permit and coordinate every inspection so you’re not left guessing. Call (877) 610-1318 and we’ll walk you through what your specific lot triggers.
In most of the burn zone, yes. Ash and burned building material can leach heavy metals and VOCs into the soil, and LA County requires environmental testing and often remediation before new foundation work can begin. That’s a step homeowners from outside the area rarely expect, and it’s one we plan into the timeline from day one. Our estimates account for it so it’s not a surprise line item later.
A full rebuild from dirt to move-in is typically running 12 to 24 months depending on slope, soil, retaining walls, and county review timelines. Remodels on unaffected homes run shorter: a kitchen is 6 to 10 weeks, a bathroom 3 to 5 weeks. We’ll give you a written timeline with your estimate, and every change to that timeline comes as a written change order, too.
Only if the scope changes, and only with your signed approval first. We write every allowance, every scope item, and every change order on paper before work proceeds. If we open a wall and find a surprise, you’ll get a written change order with a number before a single nail moves. That’s the whole point: no surprise invoices at the end. Call (877) 610-1318 for a free estimate and we’ll show you how it works.
We’ll provide itemized, written estimates that satisfy mortgage, insurance, and FEMA documentation requirements, and we’ll work with your adjuster on scope verification. We don’t act as a public adjuster, but we make sure the paperwork matches the work we actually do. Bring us your insurance scope and we’ll give you a free second opinion on whether it covers what’s really needed.
