Commercial TIs
Office, showroom, retail and municipal build-outs. Every TI we've built includes ADA restrooms.
- Offices, conference rooms, breakrooms
- Full electrical, plumbing, ceiling grid
- Suite conversions (office to automotive)
Commercial tenant improvements, custom homes and full rebuilds, RV garages, and additions. Owner-run, licensed commercial and residential, and on site from walkthrough to final inspection.
We handle the full job: plans, permits, trades and closeout. You get one contractor and one point of contact.
Office, showroom, retail and municipal build-outs. Every TI we've built includes ADA restrooms.
New homes and near-total rebuilds, including fire-loss homes rebuilt down to the shell.
Stick-built and steel RV garages sized for real motorhomes, with engineered plans and permits.
Room additions and garages that add real square footage and tie cleanly into the existing house.
Framing stage
Old ceiling and insulation torn out, then new steel-stud offices framed and wired, with the tenant's furniture protected in place.
During rebuild
Everything rebuilt but the CMU exterior walls, including raising egress window heights to current code.
Galvanized steel frame and corrugated metal roof over a long concrete pad, bolted down on steel base plates.
An owner walks every job, writes every estimate, and is the one you call when something comes up.
Desert Heat Construction is run by Warren Fait and Janeen Mierzwa. Warren brings 15+ years of hands-on trade work and has been a licensed Arizona general contractor since 2016. Janeen runs the office and financials, so bids, change orders and invoices stay clean and on time.
We've built for business owners, investors, homeowners and the City of Peoria, and we're based right here in Phoenix.
Send a few details and we'll set up a walkthrough. Plans or photos help but aren't required.
