Choosing the right window installer can make a world of difference to your home’s appearance, comfort and energy efficiency. Yet, the installation task is often underestimated, leading to costly and preventable mistakes. Knowing these common mistakes can provide clarity if you’ve ever wondered what separates good installers from the rest. V. Nanfito Roofing & Siding, Inc., a reputable local window expert, enumerates what their window experts avoid in this post.
Ignoring Rough Opening Size
Good window installers pay close attention to the rough opening requirements, understanding that the size varies depending on the window manufacturer and style. They make it a point not to force a standard size into a non-standard opening.
Misjudging Jamb Size
For installations where the jambs come attached, skilled installers make sure to add to the width of the jambs if the finished surface of the interior walls is going to be thicker than one-half inch drywall.
Neglecting Back Slope
A rough opening sill should be sloped to direct any infiltrating water back outside. Competent installers ensure this slope by cutting the cripple studs at an angle or adding a sill-wedge or sloped pan.
Poor Flashing Adherence
Window installers worth their salt will remove dust, debris and moisture from window sills and the WRB (weather-resistant barrier) to ensure proper adherence to flashing tapes and membranes.
Forgetting Regular Inspections With Nailing Fins
Good window installers secure nailing fins with care. They make regular checks to ensure the window remains centered, level, plumb and square while secured.
Not Sealing the Nailing Fins
Solid window installation includes sealing underneath the nailing fins. Additionally, qualified installers ensure that fins not integral to the window unit are sealed to the frame.
Overlooking Back Dam
A notable attribute of skilled window installers is their vigilance in installing a back dam on the sill. This prevents any unwanted water from reaching the wall cavity and the interior of the building.
Improperly Installed Head Flashing
Rather than installing the head flashing or drip cap as an afterthought, competent window installers incorporate it into the window flashing system from the outset.
Misusing Spray Foam
Experienced installers are mindful not to fill the entire cavity around the window perimeter with expanding spray foam to avoid window distortions and ensure water can escape.
Carelessness With Dirt
Professional window installers make it a point to keep their working area tidy. They avoid smearing foam and sealant on the finished parts of the window and siding, knowing that stains are adamant to remove.
