I'm Chad Konts — a licensed master plumber serving the Seacoast and Southern NH. Plumbing, heating, boilers, and emergency work. I show up on time, do the job right, and clean up when I'm done.
From a leaking faucet to a full boiler replacement. Every job gets the same attention to detail.
Residential repairs, installations, and remodels. If water runs through it, I fix it.
Specialty boiler work is what I'm known for. Keep your home warm and your system running right.
Same-day water heater replacement. Tank and tankless options, sized right for your home.
Burst pipe at 2 AM? No heat in January? Call now. I answer the phone and show up fast.
Commercial and residential. Boilers, plumbing, HVAC. Here's what clean mechanical work looks like.












I'm a veteran and a licensed master plumber. I started CSK because I believe you deserve a plumber who shows up on time, does the job right, and cleans up when he's done.
Most of my work comes from word of mouth. That only happens when you do right by people. I treat your home the way I'd want someone to treat mine.
When you call CSK, you'll always get a real person — not a phone tree.
“My name is on the truck. I don't disappear after the invoice.”
— Chad Konts, CSK Plumbing and HVACWhen I say 8 AM, I'm there at 8. You won't spend your morning wondering if the plumber's coming.
You'll know what it costs before I start. No surprise charges, no bait-and-switch. The price I quote is the price you pay.
I protect your floors, clean up after myself, and leave your home the way I found it. The job isn't done until the space is clean.
If you're not sure I cover your town, call anyway. If I can get there, I will.
Call anyway. I've built this business on showing up when people need me.
Burst pipe, no heat, sewer backup. I prioritize emergencies across my full service area.
Call or text. I'll get back to you fast.
