Residential Glass Installation

Residential Glass Installation

Window replacement and installation is one of the most cost effective ways to save energy while also increasing the equity in your home.

New windows and doors can completely change the look of your home both inside and out while adding the comfort you need during cold winters and hot summers. It’s also easier than you might think; most installations only take two to three days.

Many styles and shapes of windows are available to fit the needs of your home. Twin Peaks Glass can replace with vinyl, wood, fiberglass and even thermally improved aluminum. Sliding doors can be changed to swinging doors and vice-versa. In many situations window sizes can be changed without structural modification.

Our Installation Process

The installation process begins with removing your old window and preparing the opening for the new one. This is done by cutting around the exterior of the existing window to expose the nailing flange. The nailing flange secures the window to the framing of your home, utilizing the nail flange is the only approved method for window replacement. The old window is removed in its entirety and your interior is prepped to receive the new window. The new window is sealed to your framing and a trim board covers the nail flange. The trim board is then sealed to the window and your existing siding making an air and watertight seal to keep the elements out of your home. Never accept an installation that does not utilize the nailing flange of the window. The finished product looks as if your home was built with the new windows in place.

Twin Peaks Glass LLC offers free consultations. If you have ever considered replacing your windows call today and find out how easy it is to make your home more comfortable and beautiful for years to come.
