We get calls almost every week from Altadena homeowners who want a safe tucked into the master bedroom closet — usually to hold jewelry, watches, and a few important documents. The questions tend to repeat, so we put the most common ones in one place. If you’re weighing a for your closet, start here.
Can my Altadena home’s closet floor actually hold a jewelry safe?
Most of the time, yes — but it depends on the house. A lot of homes off Lake Avenue and around the Janes Cottages are 1920s–1940s builds with original wood subfloors over joists spaced 16 inches apart. Those can usually handle a 300–500 lb jewelry safe without reinforcement, especially if the safe sits perpendicular to the joists rather than parallel.
Newer construction up in the hills above Loma Alta Drive tends to have stronger framing and engineered joists, so weight is rarely the issue there. The two situations where we recommend a structural check: raised-foundation homes with visible joist sag, and any safe over 750 lbs going onto a second story. We can take a look before we order any anchoring hardware.
How much does safe installation in Altadena typically cost?
For a standard jewelry safe in the 150–500 lb range going into a master closet, most Altadena jobs run between $225 and $450. That covers delivery from your driveway or garage, moving the safe through the house on a stair climber or appliance dolly, bolting it to the floor with concrete or lag anchors, and walking you through the lock.
Prices climb when we’re dealing with tight staircases (common in the older Craftsman homes near Mariposa Street), second-floor installs, or safes over 600 lbs that need four people and rigging. Concrete slab anchoring usually adds about $75 because of the hammer-drill work and chemical anchors. We give you the full number before we start — no surprise add-ons.
Should the safe be bolted to the floor, the wall, or both?
For a jewelry safe in a closet, the floor is almost always the right answer. Four anchor bolts through the pre-drilled holes in the safe’s base into either the wood subfloor (with blocking added between joists) or directly into the slab. A thief can’t tip it, slide it, or carry it out — and that’s the whole point, because a 300 lb safe that isn’t bolted down can be walked out by two people with a dolly in under five minutes.
Wall anchoring is something we do for smaller wall safes or for safes wedged into a corner where floor access is blocked by tile we don’t want to drill. For a closet install with a wood or carpeted floor, stick with floor anchors.
What size and type of safe makes sense for jewelry in a master closet?
For most Altadena clients we work with, the sweet spot is a UL-rated burglary safe (B-rate or RSC) with a one-hour fire rating, somewhere between 1.5 and 3 cubic feet inside. That fits comfortably in the corner of a walk-in closet, holds a meaningful jewelry collection plus passports and a hard drive, and weighs little enough that we can install it without removing closet doors.
Skip the cheap “fire chest” style boxes from big-box stores for jewelry — the locks on those open with a paperclip. Brands we install regularly and trust for this use case include AMSEC, Liberty, and Mesa. If you already bought a safe, bring us the model number and we’ll tell you straight up whether it’s worth installing.
What about humidity? Altadena gets damp in winter.
Closets along the western side of the foothills, especially near Eaton Canyon, can hold moisture. A small rechargeable desiccant or a Goldenrod dehumidifier rod inside the safe keeps jewelry from tarnishing. We mention this because we’ve opened safes for clients five years after install and found tarnished silver — small thing, easy fix.
Do I need to change the factory combination after installation?
Yes, always. Every safe ships with a factory default code, and those codes circulate online. We change it during the install and have you set your own combination before we leave. Down the road, if you ever share the code with a contractor, a house sitter, or a family member who shouldn’t have it long-term, get a done. It takes us about twenty minutes on most electronic safes.
How long does the whole install take?
From the truck arriving in your driveway to handing you the new combination, a typical master-closet jewelry safe install runs about 90 minutes to two hours. Stair climbs, tight hallways, or slab anchoring can push it to three. We clean up the drill dust and haul off the packaging.
