Allen & Sons Plumbing and Heating
Allen & Sons Plumbing and Heating is a plumbing and HVAC company based at 834 S Perry St in Castle Rock, Colorado. Founder and owner Clayton Allen 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. The residential side covers drain cleaning, water heater replacement, re-piping and water line repairs, fixture replacement, water softeners and treatment, permitted gas lines, and vacuum breakers and hose bibs. On the heating and cooling side the crew handles forced-air furnaces, air conditioning and heat pumps, and boilers and radiant heat, a specialism the company notes many area HVAC companies will not take on. Allen & Sons also does the plumbing and mechanical scope on bathroom, kitchen and basement remodels, custom homes and ground-up commercial builds, working as the sub under a general contractor. Pricing is flat rate, quoted before work starts, with no hourly meter. The company is licensed and insured in Colorado, pulls permits where permits are required, and remains independent and family-owned with no franchisor and no private-equity owner. Office hours are Monday through Friday, 8:00 am to 5:00 pm, and the company does not run an after-hours emergency service.

FAQs
What areas does Allen & Sons serve?
Allen & Sons works out of Castle Rock, Colorado, and serves Parker, Highlands Ranch, Sedalia, Franktown, Littleton, Centennial, Greenwood Village, south Denver, Aurora, Elizabeth and Monument. That is roughly 35 miles out from Castle Rock, though the area runs further north-east than it does west.
What are your hours?
Monday to Friday, 8:00 am to 5:00 pm. Allen & Sons is closed on Saturdays and Sundays and does not run an after-hours emergency service. Calls and form requests that arrive outside those hours are picked up the next business morning.
How does your pricing work?
Flat rate. The company looks at the job, gives you a number, and that number is what you pay. There is no hourly meter and no line items you did not agree to, and the quote comes before anyone opens a toolbox.
How fast can you get here?
For an active leak, no heat or no hot water, call during business hours rather than using the booking form, because the phone is faster and urgent jobs get worked into the day. Routine work is usually scheduled within a couple of days.
Are you licensed and insured?
Yes. Allen & Sons is licensed and insured in Colorado, and the company pulls permits itself on any job where a permit is required rather than skipping the inspection.
Do you do both plumbing and HVAC?
Yes. Allen & Sons covers residential plumbing, furnaces, air conditioning and boilers, plus the plumbing side of remodels and ground-up new construction. Plumbing can be booked online, while HVAC is scheduled by phone because it runs through one technician whose calendar the office checks first.
Do you work on boilers?
Yes. Allen & Sons services and replaces boilers and radiant heating as well as forced-air furnaces. Boilers are a specialism plenty of HVAC companies will not touch, and hydronic systems are a large part of what the crew came out of commercial work knowing.
Who owns Allen & Sons?
Clayton Allen founded the company in 2020. He has worked in the trade since 1997, including 23 years of commercial plumbing and mechanical work on Colorado hospitals, water treatment plants, airports, hotels and high-rises. It is family-owned and he is on job sites.
