General contractor serving Windsor
We build decks, pergolas, fences and basement finishes for homeowners in Windsor.
What we build in Windsor
Composite Decks
We design and build composite and wood decks across Loveland and Northern Colorado: new decks, full tear-out replacements, stairs, railing and covered sections.
See composite decks →Pergolas & Patio Covers
A pergola or solid patio cover turns a deck or patio into a space you can use on a July afternoon.
See pergolas & patio covers →ADUs
An accessory dwelling unit gives you a rental, a place for family, or a guest house on your own lot.
See ADUs →Home Additions
When you need more room but don't want to move, an addition is often the better deal.
See home additions →Basement Finishing
An unfinished basement is the cheapest square footage in your house.
See basement finishing →Fence Installation
We install residential and commercial fencing across Northern Colorado: wood, vinyl, privacy, composite and chain link.

Many Windsor homes have an unfinished or dated basement, and it is usually the least expensive way to add a bedroom, bathroom or family room without changing your footprint. We handle the layout, permits, egress windows and every trade from framing to trim, and give you a fixed price before we start. See basement finishing or read our Northern Colorado basement cost guide.
