Your front door is a hole in your insulation
Walk up to your entry door in July and put your hand on it. If it's hot, that heat is moving straight into your entryway all afternoon. Add a worn threshold sweep and a cracked weatherstrip and you've got a conditioned-air leak on the sunniest wall of the house.
Builder doors in this valley fail in a predictable order: the finish chalks, the slab bows from the temperature differential between inside and out, the seal compresses, then the latch stops lining up and you start shoulder-checking the door to lock it.
A properly insulated, properly hung door fixes the comfort, the energy loss, the dust, and the security all at once. It's the highest-impact single opening in the house.
What's in our doors
Every entry door we install is built for desert exposure and real security:
- Polyurethane foam-filled cores for real insulation value
- Fiberglass and reinforced steel skins that won't warp or bow
- Multi-point locking hardware with reinforced strike plates
- Full-perimeter weather sealing plus adjustable thresholds
- Low-E decorative glass that adds light without adding heat
- Impact-rated glass options for wind-driven desert storms
Doors we install
Fiberglass entry doors
Our default recommendation for Las Vegas. Won't conduct heat like steel, won't dent, holds paint and stain through years of direct sun.
Reinforced steel doors
Excellent value and security for shaded or north-facing entries where direct solar load is lower.
Sliding glass patio doors
Low-E insulated glass, smooth stainless roller systems, and reinforced locking rails that resist lifting.
French & double doors
Matched pairs with astragal sealing and multi-point hardware so the inactive leaf doesn't become the leak.
Full-lite & decorative glass
Light without heat gain — Low-E decorative glass in privacy, textured, and clear patterns.
Security & screen doors
Ventilation options that let you open the house on the twelve nice weeks a year without losing security.
Sliding patio doors: the biggest single pane in your house
A patio slider is often 40+ square feet of glass on a wall facing full afternoon sun. When the glass package is wrong, that one opening can outweigh every window in the room combined.
We replace sliders with insulated Low-E units on stainless roller systems, set into a properly flashed and squared frame so they roll with one finger for years — not one summer.
- Low-E insulated glass rated for Southwest solar gain
- Stainless steel tandem roller assemblies
- Reinforced interlock and anti-lift locking
- Full sill pan flashing to keep water out of the wall
- Optional built-in retractable screens
- Track set true so the door stays smooth long-term
Our installation standard
Door hanging is precision work — a quarter inch out of plumb and you've bought a draft. Every install includes:
- Laser-measured openings, custom-built to the quarter inch
- Full frame inspection with stucco and framing repair if needed
- Perimeter foam insulation and code-compliant flashing
- Interior and exterior trim finished the same day
- Post-install operation, lock, and air-seal verification
- Complete cleanup and old-unit haul-away included
Why our doors, and our crews
We never subcontract — ever
100% W-2 veteran-led employees. The national window companies sell the job and hand it to subcontracted crews; the team that measures your openings is the team that installs them, and the only company on the hook is us.
Double lifetime warranty
Materials and our workmanship, covered for as long as you own the home. Not prorated.
Built for the Mojave
Glass packages and frames specified for 115° summers and relentless UV — not a national spec sheet.
Honest, same-day pricing
One visit, one written price, no four-hour pitch and no 'today only' pressure discounts.
Permits and HOA handled
We pull Clark County permits and prepare HOA architectural submittals for you.
Energy math, not guesses
We model your cooling load so you know what the upgrade should save before you buy.
Frequently asked questions
How much does door replacement cost in Las Vegas?+
Insulated entry doors typically run $1,800-$4,500 installed depending on material, glass, and hardware. Sliding glass patio doors generally run $2,200-$5,500 installed. Every quote is written and itemized before any work starts.
Fiberglass or steel — which is better for Las Vegas?+
Fiberglass is usually the better choice here. It doesn't conduct heat like steel, won't dent, and holds paint and stain through years of direct desert sun. Steel is a strong value option for shaded, north-facing entries.
Can you fix a sliding door that's hard to open?+
Often yes. Worn rollers and bent tracks are repairable. But if the frame is out of square or the glass seal has failed and fogged, replacement is the cheaper long-term call. We'll show you the difference and let you decide.
How long does a door installation take?+
Most entry doors are installed in 3-5 hours. Sliding glass patio doors typically take 4-6 hours. Same-day, one crew, cleanup included.
Will a new front door actually lower my energy bill?+
A leaking or heat-conducting door is a real load on your AC — you can often feel the temperature difference standing next to it in July. A foam-core insulated door with a full perimeter seal removes that load and stops the dust infiltration that comes with it.
