Encino Window Replacement — Local Expertise, Quality Results

Encino ranch homes with original aluminum sliding windows and aging patio doors are leaving significant energy and comfort improvements on the table — Caspi Construction replaces them with dual-pane casement windows and multi-panel sliding glass systems under proper LADBS permits.

The aluminum sliding windows installed in Encino's ranch homes during the 1960s through the 1980s were functional in their time — but their single-pane glazing and minimal frame insulation are significant liabilities in a home that experiences summer temperatures regularly exceeding 95 degrees in Amestoy Estates, Royal Oaks, and Encino Hills.

The HVAC system works harder, the home is less comfortable, and the energy bills show it.

Window replacement in Encino at this housing vintage typically means replacing aluminum sliders with dual-pane casement or awning windows — which provide better thermal performance and the natural ventilation advantage of fully operable sashes — and replacing original sliding glass doors to the patio with multi-panel folding or sliding glass wall systems that open the home to the generous backyard spaces these lots afford.

Caspi Construction is a licensed Encino windows and doors contractor (CSLB #1091631) with a 4.9★ rating.

All work is permitted through LADBS.

Our Encino Window Replacement Services

Aluminum Slider to Dual-Pane Casement Conversion

Converting original aluminum sliding windows to dual-pane casement or awning windows requires replacing the window frame within the existing rough opening — a straightforward installation in most Encino ranch homes where the wood framing is sound.

We install vinyl-clad or aluminum-clad casement windows with low-E glass appropriate to Encino's solar orientation, specifying higher solar heat gain coefficient (SHGC) values for north-facing windows and lower values for south and west exposures.

Large Patio Door & Sliding Glass Wall Systems

The sliding glass doors on Encino ranch homes are frequently the largest energy liability in the building envelope — single-pane 6- or 8-foot units that face south or west onto pool areas and patios.

We replace them with dual-pane sliding glass door systems sized to the existing opening, or with multi-panel stacking slide or folding glass wall systems that expand the opening for a more dramatic indoor-outdoor connection.

LADBS permits are required for any modification to the opening size.

Entry Door Replacement & Security Upgrades

Encino homeowners who are upgrading windows frequently add entry door replacement to the scope — addressing both the energy and security liabilities of original wooden doors simultaneously.

We install fiberglass or steel entry doors with insulated cores, multi-point locking systems, and profiles appropriate to the home's architectural character.

Window Package Pricing & LADBS Permit Management

Replacing all windows in an Encino ranch home — typically 15 to 25 windows depending on floor plan size — is most cost-effective when done as a single package: one permit application, one construction mobilization, one crew.

We design window packages that coordinate style and frame color across all openings and price the project with the efficiency that comes from a complete building scope.

Recent Window Replacement Projects Near Encino

Project 1 — Amestoy Estates Ranch Home Full Window Replacement

An Amestoy Estates ranch home had twenty-two original aluminum sliding windows — all single-pane, all in deteriorating condition with worn weatherstripping and frames that admitted drafts.

The home had a high cooling bill from a west-facing wall of windows in the family room.

We replaced all twenty-two windows with dual-pane casement windows in a vinyl-clad frame with low-E glass, specifying a lower solar heat gain coefficient for the west-facing family room units.

LADBS permits were not required as the rough openings were unchanged.

The window replacement in Encino was completed in two days and the homeowner reported meaningfully lower cooling bills in the following summer.

Project 2 — Royal Oaks Sliding Glass Wall Upgrade

A Royal Oaks homeowner had an original 8-foot single-pane aluminum sliding glass door to the pool area — a unit that was functionally sound but thermally poor and visually dated against the home's recently renovated interior.

The homeowner wanted to expand the opening to a 16-foot multi-panel stacking sliding system that fully opened the family room to the pool and patio.

We managed the LADBS permit for the structural header modification required to expand the opening from 8 to 16 feet, installed a new steel header, and completed the multi-panel sliding glass wall installation with dual-pane tempered low-E glass.

The window contractor work in Encino was completed in three days.

Project 3 — Encino Hills Entry Door and Window Package

An Encino Hills homeowner had a front facade with three original aluminum windows and a wooden entry door — all original to the 1974 construction.

The homeowner wanted to address the curb appeal deficit and energy performance simultaneously.

We installed three dual-pane casement windows in a warm bronze aluminum-clad frame, a new fiberglass entry door with a raised-panel profile in a complementary warm brown finish with brushed nickel hardware, and a new sidelight panel on the latch side.

LADBS permits were managed for the project.

The door replacement in Encino was completed in one day.
