Professional babyproofing vs DIY: four jobs are worth paying for, and the rest is a Saturday

What a professional actually does

A childproofing service typically sells two things that are priced separately: a walk-through assessment of the house, and the supply and installation of the products. The assessment is the part with the real expertise in it - someone who has seen three hundred houses spots the stair spindle gap, the unanchored range and the bedroom window that is also the fire exit faster than a first-time parent reading a checklist.

The installation is the part you are paying a trade rate for, and most of it is work you could do. That is not a criticism: the reason people hire out is almost always time and the fact that a newborn is already using all of it.

The International Association for Child Safety maintains a directory of certified professional childproofers, and that is the sensible starting point rather than a general search, because this is an unlicensed trade in most places and the association membership is the only broad credential there is.

The four jobs worth paying for

One: a staircase no standard gate fits. An opening with a round newel post on both sides, a curved bottom step, a metal railing, or two faces at 30 degrees to each other. The products exist, they are model-specific, and the wrong combination either does not fit or fits badly. A professional carries the adapters. If you want to try it yourself first, the options are on baby gates for angled and irregular openings.

Two: window guards above the ground floor. The guard has to meet ASTM F2090 with an emergency escape release, be sized to the opening rather than the window, and land its screws in something structural - which in a vinyl or aluminum frame is not obvious. Several cities also regulate guards in rented units.

Three: a pool barrier. Fence height, gate hardware and self-latching requirements are frequently set by local code, inspected, and expensive to get wrong. This is the one category where we would default to professional installation even for a confident DIYer.

Four: anchoring into plaster, masonry or stud-free wall. Anchoring to a stud is a DIY job. Anchoring a heavy dresser to lath-and-plaster, brick, or a wall where the studs are in the wrong place needs the right fixing and the judgement to know it is holding, and the failure mode here is a wardrobe on a child. The wall-type detail is on furniture anchors for drywall, plaster and brick.

The jobs that are genuinely DIY

Cabinet and drawer locks, which are adhesive or two screws and a template - how to install cabinet locks covers the whole technique. Outlet covers and plug inserts. Corner and edge guards. Cord covers and cord shorteners. Door knob covers and lever locks. A pressure gate in an ordinary doorway. Anchoring a dresser or a bookcase to a stud, which is a stud finder and two screws - how to anchor a dresser is the walkthrough. And the whole free half of the job: moving chemicals up, shortening cord loops, turning the water heater down.

That list is most of a babyproofed house. A service will quote for all of it because that is how services quote, and there is nothing wrong with buying the time - just know that you are buying time, not expertise, on those lines.

What you are installing either way

The products do not change depending on who holds the screwdriver. These three are the ones that come up in every assessment: the anchor you should fit yourself today, the stair gate that is the usual reason to call someone, and the window guard that is the clearest case for paying a professional.

How to vet a childproofer

Childproofing is not a licensed trade in most of the US, so the questions do the work that a licence would.

Ask whether they are a member of the International Association for Child Safety. Ask for proof of liability insurance, because they are drilling into your house. Ask which products they fit and whether they will fit one you have bought - a company that only installs its own range may be fine, but you should know that before the visit. Ask specifically whether the gates they fit state a certification and whether the window guards meet ASTM F2090 with an escape release; the answer tells you how much they know in one question.

And get the assessment in writing, itemised, with the products named. A list of "safety devices" is not a quote, and a named model is checkable against the manufacturer's own page - which is the standard this whole site is built on.

The middle option nobody mentions

Book the assessment and decline the installation. Many services will do a consultation as a separate line, and it is the highest-value hour in the whole transaction: you get the list of hazards specific to your house, including the ones a generic checklist misses, and then you buy the products and fit them over a couple of weekends.

Hybrid is also legitimate. Pay for the staircase, the windows and the pool, and do the other eighty percent yourself. If you would rather start from a list than a visit, work through the babyproofing checklist and babyproofing on a budget first - you may find the remaining jobs are a shorter list than you expected, and the quote becomes easier to judge once you know what is on it.
