Rear and second-story additions
We tie new floor framing into the old structure, dry in the roof before the old wall opens, and keep the house livable. Most additions run fourteen to twenty weeks from permit.
General contractor · Denver, Colorado
We frame it, permit it, and name the day you get the keys.
Summit Frame Co. builds rear additions, basement finishes, garage ADUs and structural repairs across Denver and the west Front Range. You get one licensed contractor, a written scope with every allowance spelled out, and a site lead who texts photos before you think to ask.
Site walks are free inside the I-25 and C-470 loop.

Six kinds of work we put our name on
We self-perform framing, finish carpentry and site management, and bring in the same licensed electrical, plumbing and mechanical crews on every job.
Basement finishes
Moisture test first, then egress window, radon rough-in, framing and drywall. Denver basements are dry-looking until a wet April proves otherwise.
Garage ADUs and conversions
Slab, utilities and inspections for a rentable dwelling behind the main house, drawn to Denver's accessory unit rules.
Structural repair
Failing beams, sagging headers and cracked footings, with stamped drawings from our structural engineer before a saw comes out.
Light commercial tenant finish
Dental suites, salons and small offices in RiNo and Baker, built around a landlord's schedule and a Saturday-only noise window.
Permits and inspections
We file through Denver's online permit portal, book every inspection and keep the approved set on site.

A written scope after the site walk replaces this number. Utility upgrades and soil surprises are listed as allowances, never buried.

Owners who signed the scope
“Our addition came in two weeks under the schedule they wrote down, and the one change order was priced before the carpenters touched it.”
“They found the wet footing during the moisture test, not after the drywall. That alone paid for the basement finish.”
“As a landlord I need dates. Summit gave me one and then hit it, inspection by inspection.”

What Denver owners ask before signing
Are you licensed to pull permits in Denver?
Yes. Summit Frame Co. holds a Denver Class A general contractor license and the matching registrations in Arapahoe and Jefferson counties. We email copies with the proposal, not after the deposit.
Do you do design?
We draw simple additions and basements in house. For anything with a new roofline or a structural wall we bring in an architect and a structural engineer and bill their time at cost.
How do change orders work?
Every change gets a one-page order with the price and the schedule effect. You sign it, then the crew moves. Nothing appears for the first time on the final invoice.
Can we live in the house during the work?
Usually for additions and basements, yes. We build a dust wall, protect the floor path to the bathroom and agree on quiet hours before demolition.
What do you need from me to start?
Photos of the space, a rough budget and the date you would like to be finished. Everything else we gather on the site walk.
