About Backyard Patio Extensions

Backyard Patio Extensions Done Right

Many new homes come with a small gray slab that is gone the moment a table and grill go on it. We extend the patio to the size you actually need and match or upgrade the surface.

If the existing slab is sound, we can often tie the new pour to it and resurface the whole area so it reads as a single design.

Call 720-295-9670

A visit to your property, a clear plan and careful work from base to sealer.

Almost Any Surface

Slate and Natural Stone

Ashlar Slate

Rectangular stones of mixed sizes laid in a tight, tidy grid: the most popular stamped pattern for a reason.

Questions About Backyard Patio Extensions

Still have a question?

Call 720-295-9670

Can you match my existing patio?

We can often match or complement it, and when a perfect match is not possible we use a border or an overlay to unify the old and new sections.

How big can an extension be?

That depends on your lot, setbacks, drainage and any HOA rules. We look at the yard and talk through the options.

How do I request a quote?

Call 720-295-9670 or send the form on this page. Tell us the address, what you want to build or fix and the look you like, and photos help. We follow up and set a time to visit.

Can I combine this with other work?

Yes. Many projects combine a patio, a walkway, a border and sealing, and we plan them into a single design and schedule.
