Install Windows Before Or After Siding

Northguard windows and doors a specialist in vaughan window replacement says the windows would come first in this scenario.

Install windows before or after siding.

I am installing windows and siding which one comes first. Usually around the 20 30 year mark on a home they will need new roofing siding windows and gutters. And save the rain gutters for last. Siding and exterior trim goes last out of those 3.

Windows usually go in before the siding that way they can be flashed and sealed properly. Window capping is a protective covering usually aluminum that is often added to exposed exterior frames during the installation. Do gutters go on first or last. Then the siding and windows next.

Roof always goes first on a renovation that way the roofers can t damage new siding or windows when ripping off the old roof. By installing the siding second you can ensure that your siding looks fresh and neat. If any door units jamb threshold and door slab have to be replaced i recommend having that work done before the siding and trim are installed. If you install siding first and then install windows you may run the risk in scratching or damaging the siding when removing or installing the new windows.

Windows should be installed after sheathing and before siding. The reason being is that it gives the contractors time to set the window in just how it needs to be. While it isn t essential to install retrofit windows before hanging siding it s a good idea to keep from bumping or marring the new siding which could happen if you install the windows last. That said if your siding is truly falling apart or needs immediate attention it makes more sense to approach this part of the project first if you can t afford to do both right away.

Find a contractor who can do both. I have heard the door and windows can be repaired or replaced after the siding is installed. In our professional opinion we suggest doing your roof first. Now if you have decided to have both projects done at the same time one will need to be installed first.

Homeowners commonly ask us which project should i do first.
