Do I need to replace all of my windows?

Not at all, while some projects replace all or most existing doors and/or windows – there are plenty of projects that are single door installation or just a few windows.

Can I install new windows myself?

You can hire out installation for your new windows or doors, absolutely. Keep in mind that Cornerstone doesn’t offer turnkey construction services for every project, either.

What condition will my house be in during the construction and installation processes?

That depends largely on who does the construction and installation. While we can’t speak for other contractors and businesses, when Cornerstone is installing your windows and/or doors – we keep your home in the best condition possible. This includes sectioning off the construction area with plastic and paper – cleaning every day and doing our very best to mitigate the home being impacted outside of the construction zone.

What does the construction process look like?

First day we lay out the job and go over specifics like lighting, flooring conditions, etc.

W e also set up containment, this includes ram board and black paper to protect flooring and landscape, we also cover important items like furniture, chandeliers, and nearby pools with plastic.  We then build a shoring wall that acts as a support for the ceiling above the opening we are about to demo, and we board it up with plywood, tape and plastic to keep dust and debris from entering the house.

During demo, the first day is very noisy. This is because we need to demo stucco, and take down the wall where the door is about to go. Framing involves multiple people to properly set and secure the beam that is going above the door. The concrete cut is the loudest part.  A concrete saw will cut into the foundation to create a channel that we can drop the sill of the door into.  This allows the final threshold to be flush with the top of the finish floor.

Door install – frame is assembled and installed perfectly level.  If the door is not perfectly level it will not operate properly.  Sometimes this causes the door to be out of level with the flooring because most houses do not have perfectly level foundations over a long span.  The door is then fully sealed to eliminate the opportunity for water intrusion around the frame.

Lathe – this is the black paper and chicken wire that acts as the water proof layer over the wall, and the surface that we will be able to add stucco on top of

Stucco – there are 3 different layers of stucco. Stratch coat and brown coat are typically done on the same say.  The brown coat is a porous surface that needs to be allowed to dry/cure for up to 48 hours before the final layer of the stucco (color coat) can be applied.  Once dried the color coat will then be applied which fills into the pores of the brown coat and seals everything in.  This coat can have a variety of pigments added to it.  Our team will select the closest color possible to your existing paint (essentially like a colored primer).  Please note this will not be exact and you will still need to paint on top of it for a perfect match.  Textures of stucco vary but our team will get as close as possible to your existing stucco.. note that stucco essentially like a signature and no two signatures are exactly alike.

Drywall  is done at the same time as the stucco portion.  We first nail, tape and mud the drywall.  Once drywall mud has dried we apply a texture to it to match the existing drywall texture as closely as possible.  For smooth drywall, your painter will be responsible for any sanding or priming required before they begin to paint.
