Frequently Asked Questions
What home repairs should I never DIY?
Never DIY electrical work beyond basic outlet replacement (fire and electrocution risk), gas appliance installation or repair (gas leak danger), structural work like removing walls (can compromise your home's integrity), major plumbing like sewer line work (expensive damage potential and permits required), and roof repairs (fall risk). These all require licensed professionals.
Is DIY really cheaper than hiring a professional?
For simple tasks like painting, caulking, and changing air filters, DIY is almost always cheaper. But for complex projects, DIY can cost more if mistakes require professional correction. Consider: professionals get material discounts, work faster, provide warranties, and carry insurance. A botched DIY plumbing job can cause water damage costing far more than the original plumber's fee.
How do I find a good contractor?
Get referrals from neighbors, check that contractors are licensed and insured, read reviews on multiple sites, get at least 3 quotes for any job over $500, ask about warranties, and get everything in writing before work begins. Never pay the full amount upfront — a standard arrangement is 30-50% deposit with the balance on completion.
What electrical work can I do myself?
You can safely replace light fixtures (with the power off at the breaker), swap outlet covers and switch plates, replace light bulbs and lamp sockets, and install battery-powered devices like smoke detectors. Anything involving new wiring, new circuits, panel upgrades, or 240V appliances should be done by a licensed electrician.
When is it worth hiring a professional?
Hire a professional when safety is involved (electricity, gas, heights, structural), when permits are required, when the cost of a mistake exceeds the cost of hiring, when specialized tools are needed that you'd only use once, or when the job is time-sensitive and you lack experience. A good rule: if you have to ask whether you can DIY it, you probably shouldn't.
