The guy behind the quotes.
T. Darby Contracting is one person — Thomas Darby, licensed PA home-improvement contractor based in Lock Haven. Here's exactly what you're hiring.
The person who measures your job, writes your quote, and swings the hammer is the same person. That's not a staffing limitation I apologize for — it's the reason the quote matches the work. I'm registered with the Pennsylvania Attorney General as a Home Improvement Contractor (HIC #PA2199962), I carry insurance, and I hold EPA 608 Universal certification for refrigerant work on any equipment type.
How I work is simple. I look at the job before I price it. You get a written quote within 48 hours — a scope you can hold me to, not a phone number that grows. No deposit until you say go. And my workmanship carries a one-year warranty: if something I built fails because of how I built it, I come back.
What fills the calendar is the range you'd expect from a one-person shop in a small county: carpentry and flooring, structural work, HVAC, and cleanup after water gets somewhere it shouldn't. The specifics are in the portfolio — a site-built structural box beam in Lock Haven, designed by an engineer and signed off by an inspector (2023); a Mitsubishi hyper-heat mini-split that keeps making heat at 13 below (2024); custom trusses and a metal roof built over a failing mobile-home roof in Loganton (2024); and a second-floor washer leak in Lock Haven that ran from containment and mold remediation through new subfloor, ceiling, and flooring (2025). The full list of what I take on is on the services page.
I work out of Lock Haven, 17745, and Clinton County is home turf — Mill Hall, Avis, Loganton, Beech Creek, and Jersey Shore are all normal drives, with the per-town detail on the service areapages. A lot of the housing stock here is old; roughly a third of Lock Haven's homes went up before 1940, so I check subfloors for flatness and moisture before anything decorative happens and assume an old house is hiding something. When a job needs a permit — a structural beam, a mini-split — I find out before the first day, and the filing is mine either way.
The other half of my working life is software — I build web apps and data tools for small organizations at software.tdarby.com. It shows up in the contracting work in one specific way: documentation. Line-item estimates, itemized insurance scopes, photos of what was behind the drywall. Paper trails are a habit I can't turn off.
Off the clock, I build beds with the local Sleep in Heavenly Peace chapter — there's a case study of the volunteer builds in the portfolio — and serve with several Clinton County community organizations. The long version of that story lives at personal.tdarby.com.
The questions people actually ask — deposits, warranty, permits, insurance claims, scheduling — get straight answers on the FAQ.
