The short version
I'm Dave Collins. For the past 15 years I've been the guy with the toolbox in the driveway on Saturday mornings, fixing things mostly because I messed them up the first time.
How I got here
The first house I bought — back in 2011 — taught me more about plumbing than any book ever could. It taught me mostly because I did everything wrong. I flooded a bathroom, I overpaid a contractor by about $1,200 for a job I could have done myself, and I bought "premium" paint that peeled off a bedroom wall in nine months.
What changed things for me was the day I hired a licensed electrician to check some wiring I'd done myself. I expected a lecture. Instead, he walked me through what I'd gotten wrong, step by step, and never talked down to me. That's the kind of help I try to give here: straight, practical, numbers-first advice from someone who learned the hard way so you don't have to.
Since then I've renovated three of my own homes — kitchens, bathrooms, flooring, insulation, a deck that outlasted my marriage to that particular design trend — and along the way I've kept notes on everything: how much paint a room actually takes, how many tiles you really need (plus waste), how much concrete for a patio slab. The calculators on this site started as those notes.
Why this site exists
Home improvement content online falls into two camps: pros talking over your head, or listicles that never get to the point. I started this site to sit in the middle — practical guides written for homeowners who want real numbers and clear steps, not fluff.
Everything here is free, and it always will be:
- Step-by-step DIY guides covering the projects real homeowners tackle: painting, tiling, flooring, basic concrete work, lighting upgrades, insulation, drywall repair, and more.
- Working project calculators that do the math for you — paint coverage, tile and grout quantities, concrete volume, lighting wattage, air conditioner (BTU) sizing, and others. Punch in your measurements, get a realistic material estimate.
- Cost and material breakdowns so you walk into the hardware store with a list instead of guessing.
Who this is for
If you own a home (or you're about to), you're handy enough to try, and you'd rather spend an hour learning than $300 hiring someone for a job you could handle — this site is for you. Beginners are welcome. Every guide assumes you're starting from zero and builds from there.
The mission
DIY shouldn't mean guessing. Every guide and calculator here has one job: help you plan the project right, buy the right amount of material, and finish without the expensive surprises I ran into. Skip my mistakes. Get it right the first time.
