IN THE TRADE SINCE 1997 · FAMILY-OWNED
THREE DECADES IN. NOW IT'S YOUR HOUSE.
Clayton Allen's background is Colorado infrastructure: hospitals, water treatment plants, airports, hotels, high-rises. Allen & Sons is what happens when that standard shows up in a crawlspace.
THE ARC
Clayton started in the trade in 1997. Commercial plumbing is unforgiving: a hospital does not get to have a leak, an airport does not get to wait until Monday. For 23 years he worked in a world where the inspector reads every joint, the schedule does not slip, and the words "good enough" do not appear on the drawings.
Residential work runs on different assumptions. Cheaper fittings, faster passes, an hourly meter that charges the customer for the crew's learning curve. Clayton had spent two decades watching homeowners get the discount version of a trade he knew could be done right.
So in 2020 he started Allen & Sons — commercial-grade methods at residential scale. Flat rates, so the number you are quoted is the number you pay. A crew trained the way commercial crews get trained. Work that would pass an inspection nobody is going to run.
Today the company covers plumbing, HVAC — furnaces, air conditioning and boilers — and the plumbing side of remodels and ground-up new construction, across From Aurora and south Denver down to Monument, and east to Franktown and Elizabeth — roughly 35 miles out from Castle Rock. Still family-owned, still independent, and still the same standard.

Founder & Owner
ABOUT THE COMPANY
Who is Clayton Allen?
Clayton Allen is the founder and owner of Allen & Sons Plumbing and Heating. He has worked in the trade since 1997, spending 23 years on commercial plumbing and mechanical work across Colorado — hospitals, water treatment plants, airports, hotels and high-rises — before starting the company in 2020.
When was Allen & Sons founded?
Allen & Sons was founded in 2020 in Castle Rock, Colorado. It is family-owned and still operates out of Castle Rock.
Is Allen & Sons owned by private equity?
No. Allen & Sons is independent and family-owned. Clayton Allen owns it, there is no outside investor setting prices or service targets, and no franchisor taking a cut. This gets asked often enough to be worth answering plainly — a great many plumbing and HVAC companies in the Denver metro have been bought by consolidators in the last few years, and it usually shows up in the pricing.
Is Allen & Sons a franchise?
No. It is a single independent company operating out of Castle Rock, not a territory licensed from a national brand. The person who owns it is on job sites.
What makes commercial experience relevant to my house?
Commercial and institutional work is inspected joint by joint by people paid to find problems, and a hospital cannot have a leak or an unplanned shutdown. That produces habits — testing before closing walls, pulling permits, documenting work — that most residential plumbing never demands. Those habits are what we brought to houses.
