The Tools Every Homeowner Should Own (A Contractor’s Honest List)

I get asked this a lot. Clients finishing up a kitchen remodel or a bathroom renovation want to know: “What should I keep around for the stuff in between?” Good question. This is my honest answer, built from years of working on homes throughout Arcadia and the broader SGV.

I’m not here to sell you a 200-piece tool set from a big box store. Half of that stuff will never leave the case. What I’m giving you is the short list that actually gets used, with real reasoning behind each item. And yes, I’ll tell you what not to DIY even if you have every tool on this list.

The Hand Tools You’ll Use Every Single Week

These are the tools that live on the workbench, not in a drawer. If you’re only going to buy one category, this is it.

A 16 oz. framing hammer. Not a 20 oz., not a finishing hammer. A standard 16 oz. with a smooth face is what you want for everything from hanging pictures to light demo work. Get one with a fiberglass handle, not wood. Wood handles crack. Mine is a Estwing and I’ve had it for twelve years.

A quality 25-foot tape measure. Stanley FatMax or similar. The wide blade matters because it won’t fold back on you when you’re measuring something solo. I’ve replaced cheap tape measures six or seven times; I stopped buying them. The $18 version outlasts three $6 versions.

A 4-foot level and a torpedo level. The torpedo level fits in a pocket and handles most everyday tasks. The 4-foot level is what you use when hanging cabinet doors, checking window sills in these older Arcadia ranch homes, or confirming a floor is actually flat before you lay tile. Both are necessary. Neither needs to be expensive -- a decent aluminum level from a hardware store works fine.

A set of screwdrivers, not a single one. #1 and #2 Phillips, a couple of flatheads in different widths. Skip the multi-bit screwdrivers with the interchangeable tips. They strip. Buy individual drivers with thick ergonomic handles and you’ll use them for decades. Klein or Wiha.

A good set of pliers. Needle-nose, slip-joint, and lineman’s pliers. The lineman’s pliers are technically electrician’s tools, but they’re also the best general-purpose pliers I know of for gripping, twisting, and cutting wire or zip ties. Knipex if you want to buy once. Channellock works fine too.

A utility knife with fresh blades. This is the most underrated tool in a homeowner’s kit. Opening packages, scoring drywall, cutting weatherstripping, trimming caulk lines. Keep a 10-pack of replacement blades with it. A dull blade is more dangerous than a sharp one because you push harder.

Power Tools Worth Owning

I’m going to keep this short. Most homeowners don’t need a shop full of power tools. They need two or three that cover the widest range of tasks.

A cordless drill/driver combo. This is the non-negotiable. Get an 18V or 20V brushless motor -- Milwaukee M18, DeWalt 20V, Makita 18V. Pick a platform and stick with it, because the batteries are the investment. Avoid no-name drills; the brushes wear out fast. A brushless motor will outlast you at normal homeowner use rates. Buy the combo kit (drill + impact driver) rather than drill alone -- the impact driver is what you actually want for driving screws.

A circular saw. You don’t need a table saw. A 7-1/4” circular saw with a decent blade will handle trim work, cutting plywood, and occasional framing cuts. Again, stay on your cordless platform if possible. If you buy a corded version, Skilsaw is still the standard.

An oscillating multi-tool. This is the tool I wish I had recommended to homeowners ten years ago. It cuts, sands, scrapes, and grouts. It’s the only tool that can undercut a door casing to slide in new flooring without removing the trim. It’ll also cut out a section of drywall cleanly, remove old caulk, and get into corners that nothing else reaches. I use mine on almost every job.

Safety Equipment: Non-Negotiable

Most SGV homes built before 1980 have some combination of older insulation, lead-based paint, and possibly asbestos in floor tiles or joint compound. I’m not saying this to scare you -- I’m saying it because the safety gear below isn’t optional if you’re doing any demo or cutting in an older home.

Safety glasses. Not sunglasses. ANSI-rated safety glasses. Keep two pairs: one clear for indoor work, one tinted for bright outdoor conditions. They cost $8. A trip to the ER costs more than your tool budget.

N95 or P100 respirators. A basic N95 is fine for dusty work, painting, and general shop use. If you’re cutting into walls in a pre-1980 home -- including most of Arcadia’s original housing stock -- use a P100 half-face respirator. It’s overkill for hanging a picture; it’s the right call for cutting a hole through an old plaster wall.

Work gloves, not garden gloves. Leather palm gloves with a back that breathes. Not the all-leather ones that make you sweat, not the thin fabric ones that do nothing. Cut-resistant gloves for glass or sharp metal work. Home Depot carries decent Mechanix-style gloves for around $20.

A basic first aid kit in the garage. Superglue for small cuts (the contractor field fix, and it works), gauze, adhesive bandages, saline eye wash. None of this is dramatic. All of it gets used eventually.

The One Splurge Worth Every Penny

If I had to pick a single tool to upgrade from the homeowner tier to the professional tier, it’s a laser level. Not a traditional vial level -- a self-leveling laser that projects a horizontal and vertical line across the room.

Hanging a row of cabinets, installing tile backsplash, running a chair rail, aligning a gallery wall -- all of these tasks that take 20 minutes of measuring and re-measuring become five-minute setups with a good laser level. A Bosch GLL 3-80 or similar runs $100-$150. It’s the tool that makes everything else faster and more accurate. I’ve used one on every kitchen and bathroom job for years.

What NOT to DIY (Even With the Right Tools)

Owning good tools doesn’t make everything a DIY project. Here’s the short list of things I’d tell any homeowner in Arcadia or Temple City to call a licensed contractor for, regardless of their tool collection:

• Any electrical panel work -- panel upgrades, new circuits, or anything involving the main breaker. This is permit-required work in California and genuinely dangerous if done wrong.
• Main water line or sewer work -- the repair is complex, the tools are specialized, and the consequences of a failed DIY repair are bad. Plumbing work that touches the main lines belongs to a licensed plumber.
• Anything structural -- removing a wall, cutting a beam, modifying a foundation. You may have the tools to do the physical work; you don’t have the engineering background to know what’s load-bearing and what isn’t without a plan and a permit.
• Asbestos or lead abatement -- if you find suspicious floor tile, old pipe insulation, or textured ceiling material in a pre-1980 home, stop and get it tested. The SGV has a lot of homes in that era. This is a licensed abatement job, not a weekend project.

This isn’t me trying to generate business. It’s me telling you what I’ve seen go wrong. A good tool kit and honest self-assessment of your skill level is the right combination. If you’re ever unsure, the free estimate call costs nothing and usually takes 20 minutes.
