Errors Skilled and Experienced Window Installers Don’t Make

Choosing the right contractor for your home window replacement project can help ensure its success. Make sure you hire a reputable installer to make the most of your investment. Before signing anything, you should do your research, ask for proof of license and contract, and read reviews.

Errors Skilled and Experienced Window Installers Don’t Make

Here are mistakes good window installers don’t make.

Improper Sizing

An experienced installer knows that window openings vary by manufacturer and window style. While windows can be made to fit nearly all sizes of rough openings, manufacturers still build standard sizes.

No Back Slope

The sill on a rough opening must be sloped to ensure water safely flows away from your home. Contractors achieve this by cutting cripple studs at an angle or by including a sill-wedge or sloped pan once a rough opening has been framed in.

Using the Wrong Jamb Size

With replacement windows that come with jambs, the width of the jambs should be added if the finished surface of the interior walls will include plaster, tongue and groove, or anything that is thicker than ½ inch drywall. Your installer should add the width of a jamb when installing a window on a sheathing that’s at least 7/16 inches in width.

Faulty Flashing Sealing

A good installer will make sure the sills are clean and free from debris before so the flashing tapes and membranes adhere properly. Certain kinds of tapes and membranes fail to adhere to cold weather. Installers must only use products that meet the manufacturer’s guidelines when it comes to cold weather applications.

Working With Dirty hands

As much as possible, foam and sealant must not touch the finished parts of a window. Removing stains from unfinished wood can also be difficult. Experienced window contractors always have an extra pair of gloves with them for sealant and foam application.

Reviews

"Quality product, quality workmanship. Everyone I interacted with at Renewal by Andersen of SW Missouri had pride in their work from sales to financing to project oversight to installation. It must be a great company to work for because that shows in the professionalism of the staff. Best of all, they want happy customers and go out of their way to make sure that happens. Yes, I love my windows (but I knew I would--it's a great product). Friendly, helpful, easy financing, and yes--they pass costs on to the customer for this, but it meant that I was able to get the windows I wanted and needed for my creaky, lopsided old house. Couldn't be more pleased."

"The company representative who met with me initially was very direct, told me how the process would go, explained about why Anderson windows are of such good quality and how they stand by their products and their workmanship. My 3 windows arrived when they said they would, & the men who installed them were very professional, polite, & efficient. They showed me how the windows work and left the room as tidy as it was before they did the installation."

"We just had our windows done by Renewal. They kept us informed about the progress of manafucture & installed at the approximate date. Good qualtity & if you didn't know that there were screens on the windows you would think they were missing. Very clear view. Great in this hot weather, the house stays cool."
