What Our Windows & Doors Service Includes
Window Installation
New window installation starts with measuring every rough opening individually, because Los Angeles homes range from 1920s Spanish Revival stucco to 1970s post-and-beam hillside builds, and no two openings are identical. We pull the old unit, inspect the framing for rot or termite damage, flash with membrane and metal as needed, set the new window, insulate, and trim it out. You get a written scope before we start, and any hidden framing repair gets a written change order before it touches the job.

Door Installation
Front doors, back doors, and interior doors all sit differently in Los Angeles weather, especially west-facing entries that take direct afternoon sun. We install pre-hung doors, slab doors, and full door systems as part of our Best Windows & Doors in Los Angeles, CA service, squaring jambs, shimming properly, and setting thresholds so they close without dragging or leaking. We also handle security upgrades like reinforced strike plates and multi-point locks for homeowners in neighborhoods like Silver Lake and Los Feliz who want better protection without giving up style.

Window Replacement
Window replacement in Los Angeles is usually driven by failed seals, fogged glass, or aluminum frames from the 1960s and 70s that conduct heat like a skillet. We replace with vinyl, wood, or fiberglass units regardless of what’s coming out, and we match stucco and trim with minimal disruption to your exterior. Most replacement jobs take one to two days for a typical Los Angeles home, and we haul away every old window and all debris.

Impact Windows & Doors
Impact windows and doors are increasing in Los Angeles as homeowners in canyon areas like Runyon Canyon, Encino Hills, and parts of the Palisades rebuild with wildfire hardening in mind. These units use laminated glass and reinforced frames to hold against wind-driven embers and pressure changes. We install impact-rated products from PGT and CGI, and every job includes proper flashing and anchoring per current California building code. If your insurance company is asking about impact ratings, we can spec the exact products you need.

Sliding & Patio Doors
Sliding and patio doors in Los Angeles take a beating from sun, salt air, and daily use, especially in older Rancho-style homes from the 1950s and 60s where original aluminum sliders are now binding and leaking. We replace sliders with modern vinyl or aluminum units, including multi-slide and lift-and-slide systems for larger openings. We also fix existing sliders where the rollers are shot or the track is bent, saving you a full replacement if the frame is still sound.

Glass Railing Systems
Glass railing systems are common on Los Angeles decks, balconies, and stair landings where the view matters as much as the safety. We install frameless and semi-frameless glass railings with stainless or aluminum hardware, engineered for California seismic and wind loads. If your current railing is rusted-out or the glass is cracked, our crew can replace panels and hardware without rebuilding the entire deck edge.

Brands We Service for Windows & Doors
We install and service Simonton windows throughout Los Angeles, and we know their vinyl lines well enough to spec the right glass package for a Craftsman in Highland Park versus a mid-century in Baldwin Hills. We’ve installed hundreds of Simonton units over the years and we order direct from authorized suppliers, so your warranty is intact and parts match.
When a home needs impact-rated products, we work with PGT and CGI. These aren’t off-the-shelf windows; they’re engineered for specific wind and impact zones, and we’ve installed both brands in Los Angeles hillside communities where wildfire hardening is becoming standard. Whether you have Simonton, PGT, CGI, or any other make, we can service it and give you a straight answer on whether repair or replacement makes more sense.
Signs You Need Windows & Doors Right Now
- Drafts you can feel around closed windows. If cold air moves through the edges of a closed window in January, the weatherstripping or the frame itself has failed. In Los Angeles, the marine layer keeps moisture against west-facing windows, which rots wood frames and degrades seals faster than most people realize.
- Visible daylight around the door perimeter. If you can see light between the door and the jamb when it’s closed, the door is no longer sealing. That gap is also how you’re losing conditioned air and letting dust from the Santa Anas into your home. A new threshold and weatherstripping might fix it, or the slab itself may need re-hanging.
- Fog or condensation between double panes. Condensation between glass panes means the seal has failed and the insulating gas has leaked out. You’re now paying to heat and cool a window that doesn’t insulate. The fix is glass replacement or a new sash, which we handle without tearing out the whole frame.
- Windows that stick, won’t lock, or slam shut. Warped frames, swollen wood, or failed balance springs make windows hard to operate and, worse, impossible to secure. A window that won’t lock in Los Angeles is an invitation to anyone casing the block. We replace balance systems, realign tracks, and if the frame is too far gone, we’ll tell you straight and replace the unit.
- Sun-faded floors and furniture near south-facing glass. Los Angeles gets over 280 days of sun a year, and older single-pane windows let UV through that bleaches hardwood and upholstery. Low-E glass rejects most of that UV while keeping the view, and it pays for itself in lower cooling bills and fewer faded rugs in rooms facing the Hollywood Hills.
Our Windows & Doors Process - Step by Step
- 1
Measure and scope. Tom or one of his sons walks your home, measures every opening, and checks the surrounding framing. We write down the exact sizes, materials, and scope in a line-item estimate. No allowances that aren’t on paper; the allowance that isn’t on paper is a surprise waiting for a date.
- 2
Written estimate and product spec. You get a detailed written estimate with the window brand, glass package, and door hardware spelled out. We also flag any likely framing repairs before we start, so you’re not surprised when the old window comes out and the sill is soft. Our published offers apply here: $40 off any repair over $200, and a free second opinion on any other written estimate.
- 3
Permit and schedule. On any eligible job, we pull the permit and schedule the inspection. The permit inspector works for you, not for me. That’s why I like him. We confirm your install date and crew arrival window, and our people show up in Barrett & Sons shirts, background-checked.
- 4
Installation day. We protect floors and furniture, tear out the old units, repair any framing we flagged or discover, and install the new windows and doors with proper flashing, shims, and insulation. Every change order is written before any scope change touches the job. If we open the wall and find something unexpected, you hear about it and approve it first.
- 5
Cleanup, walkthrough, and Done Right Promise. We haul away old windows, doors, and debris, then walk the job with you and check every unit for operation and seal. Your 90-Day Done Right Promise is written on the contract: if it’s not done right, Tom comes back and makes it right, one call.
