DIY vs Pro: Which Exterior Jobs to Hand Off

Six months after closing on our house near Tottenville, on the south shore of Staten Island, I built a spreadsheet listing every exterior project I figured I’d knock out myself. It had line items like “regrade the side yard” and “replace the front steps” sitting there like they were Saturday-afternoon chores. A year in, I’ve actually finished some of it, hired out plenty more, and botched one job badly enough that I had to pay a professional to undo my work before he could even start his own. What follows is the honest version of that spreadsheet — what a beginner can realistically take on, what’s worth handing off, and what it actually cost me.

How I learned to draw the line

The rule I landed on, after the steps went sideways, is simple: I’ll do a job if a mistake just means redoing it, and I hire the job if a mistake is structural, dangerous, or hard to undo. A bad coat of paint means I repaint it next weekend. A bad footing means a wall leaning into the neighbor’s driveway. Once I framed it that way, most decisions made themselves.

Height turned into the other dividing line. Anything that puts me more than a step-ladder off the ground now goes to someone else, because OSHA’s data on falls in construction is not something I want to test personally, and I’m neither trained nor insured the way a crew is.

The jobs I’ve kept for myself

None of these can hurt the house if I mess them up — which is exactly why they made the cut:

• Caulking and weatherstripping — did it last fall, about $70 in materials, saved a couple hundred dollars in labor
• Mulch beds and curb-appeal planting — genuinely enjoyable, runs $150 to $400 in materials
• Gutter cleaning from a stable ladder against our one-story roofline
• Painting the front door and shutters
• Replacing house numbers and the mailbox
• Pressure washing the walkway — a rented washer is about $50 to $90 a day and took ten years off the look of our concrete

The bluestone steps that changed my mind

Masonry is where I stopped trusting myself. I tried resetting two loose bluestone treads on the front stoop, cracked one, and set them out of level so water ran back toward the house instead of away from it. A local mason came out, reset both steps, and repointed the mortar around them — what masons call tuckpointing — for $900. It was worth every dollar just to have the drainage right again.

That job is also what pushed me toward hiring out roof work, second-story gutters, exterior electrical for lighting, and anything touching the foundation or grading. A retaining wall over about three feet, full siding replacement, and driveway work all fall in the same category. When I’m collecting quotes for jobs like these, I lean on this rundown of understanding exterior renovation estimates so I’m comparing bids properly instead of just chasing the lowest number.

Where DIY and hiring out overlap

Some projects only belong on the DIY side if you’re honest about your patience and your tools. A simple paver walkway on a flat, well-draining lot is doable for a determined beginner, but the base prep is brutal manual labor, and one bad slope means standing water instead of a dry walk. Extending a downspout is easy; running a French drain across an entire yard is not.

Painting siding I can reach is fine, but scraping and prepping old trim on a pre-1978 house means testing for lead first, and often calling in a certified pro. A lot of the older housing stock here on Staten Island falls inside that window, so I don’t guess — I test.

Why hiring out stopped feeling like failure

I used to treat hiring a pro as admitting defeat. Now I treat it as buying down risk. If a mason’s job costs $900 and my botched version would cost roughly $1,500 to fix, plus my entire weekend, the pro was the frugal choice, not the expensive one. The trick is figuring out which category a job belongs in before you start — not halfway through, once the mortar’s already setting. When I’m not sure, I still ask a contractor for a quote even if I’m leaning toward doing it myself, because the estimate visit usually teaches me something about what the job actually involves.

Questions I get asked about DIY versus hiring out

What’s the one job beginners shouldn’t DIY? Structural masonry — steps, retaining walls, foundation work. A mistake there messes with drainage and safety, and fixing a bad DIY attempt usually costs more than hiring a mason in the first place would have. I know because it cost me $900 to find out.

Is it cheaper to repair or replace steps once you’ve botched a DIY attempt? In my case, repair — a professional reset and remortared both bluestone treads for $900. Left alone, my mistake would likely have run closer to $1,500 to correct, since a pro often has to undo bad work before starting the real fix.

Do older homes need special care before painting or repairing? Yes — if your house predates 1978, test for lead before scraping or sanding old trim. A lot of Staten Island’s older housing stock, including ours near Tottenville, falls in that window, so I test rather than assume.

How do you know you’re in over your head mid-project? If the job suddenly needs a tool you don’t own, puts you above a step-ladder, or a mistake would send water toward the house, stop and call for a quote. There’s no shame in it — pros would rather bid a clean job than untangle a half-finished one.

Does doing part of the work yourself lower a contractor’s price? Sometimes. Site prep, hauling debris, or demolition can shave labor hours off a bid. But get it in writing first — a pro who has to redo your prep work may end up charging more, not less, than if they’d started from scratch.
