Expert Irrigation And Sprinkler Systems in Centennial, CO, USA

Irrigation and sprinkler systems in Centennial, CO face real pressure from the local environment. The Front Range's clay soil drains slowly, freeze-thaw cycles stress buried lines each winter, and active Denver Water drought restrictions limit outdoor watering to two assigned days per week. A system that wastes water or runs at the wrong time can result in citations, dead turf, or both. Sentry Property Service works with homeowners across Centennial, Greenwood Village, Littleton, Highlands Ranch, and the broader Denver metro to design zone layouts that match each property's soil, slope, and sun exposure. We handle new installations, head and valve repairs, seasonal startups, winterization, and controller programming. Whether your home is in an established neighborhood with an aging system or a newer build that needs its first full setup, we can get your irrigation running efficiently and within your utility's current schedule. Call us to schedule a visit.

What's included

Zone layouts matched to your yard's soil type and slope reduce dry patches and soggy spots
Correct controller programming keeps your system within Centennial's active watering-day restrictions
Seasonal winterization protects buried lines and heads from Front Range freeze-thaw damage

FAQ

Irrigation And Sprinkler Systems FAQ

Common questions from property managers and HOA communities about irrigation and sprinkler systems across managed properties in Centennial, CO, USA.

Can you set up my sprinkler controller to follow Centennial's current watering restrictions?

Yes, we program controllers to run only on your utility-assigned days and during allowed hours. Centennial homes served by Denver Water are currently limited to two watering days per week, with no irrigation between 10 AM and 6 PM.

Do I need to winterize my sprinkler system in Centennial every year?

Yes, winterization is necessary in Centennial because freezing temperatures can crack pipes, heads, and valves. Skipping it often leads to costly repairs when the system starts back up in spring.

My Highlands Ranch lawn has dry patches in the same spots every summer. Can you fix that?

Recurring dry patches usually point to misaligned heads, clogged nozzles, or a zone that is not covering the area evenly. We inspect each zone and adjust or replace components to restore consistent coverage.

Does Sentry Property Service handle sprinkler repairs, or only new installations?

We handle both repairs and new installations across Centennial, Englewood, Aurora, Lakewood, and other communities we serve. Common repairs include cracked heads, leaking valves, broken lateral lines, and controller issues.

How do I know if my older Centennial sprinkler system needs repair or full replacement?

Dry zones that reappear each season, water pooling near heads, and controllers that no longer hold a schedule are signs a system needs attention. We assess the condition of your existing setup and recommend the most practical path forward.

Do you service sprinkler systems in Littleton and Greenwood Village, or only Centennial?

We serve homeowners across Centennial, Littleton, Greenwood Village, Highlands Ranch, Denver, Aurora, Lakewood, Parker, Lone Tree, Arvada, Westminster, Thornton, Wheat Ridge, Golden, and Englewood. Contact us to confirm service for your address.

Great company to work with! Highly recommend!!

Sentry Landscaping We have used them for the past six years and they are wonderful. We are in property management and they do a lot of our properties. They do a really good job on limited budgets. They truly are amazing guys they go above and beyond. They’re always trying to find ways to help us through the summer drought, trying to make sure we don’t lose shrubs and trees. I really would highly recommend them if you are looking for an honest and hard-working landscaping company.

Sentry did a great job on a couple job sites for me and assisted me in getting a great quote Highly recommend Sentry

Great small business, they are polite and always get the job done. They do what they say and are affordable. You won’t be disappointed , give them a try for all your landscape needs.

Great company to work with.

Troy and the team at Sentry Property Services are simply outstanding! Their communication is next level. They keep you informed every step of the way, respond quickly, and always follow through on what they promise. The quality of their work is top notch, and it's clear they take pride in every project they touch. In the landscaping world, finding a contractor this reliable is rarer than finding a weed-free flower bed in July. Troy and his team consistently exceed expectations, and their attention to detail is second to none. If you're looking for a company that delivers great results and even better customer service, Sentry Property Services is the clear choice.

Sentry provides excellent professional service. They provide regular lawn care to our HOA property in Denver. They also updated our whole property with new landscaping, providing all new grass (sod and native), as well as landscaping rocks around bushes, and ensuring our sprinkler system is running properly. We appreciate their personal and prompt service. We definitely recommend.

Logan and Sentry Property Group have exceptional customer service and perform high quality work. They handle the property management duties within our HOA and have been wonderful to work with since day 1.
