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.

"Renewal by Anderson is definitely the way to go for replacement windows. A representative will come out to your house to discuss window replacements, their Fibrex windows, and cost. You do not have to do all the windows at the same time. We chose only to do 10 windows at this time. The price quoted is good for a full year. A few days later another Representative will come out to expertly measure all windows you are choosing to replace. These measurements are sent to the Renewal by Anderson Factory, where your replacement windows are made. Soon after your order has been processed an installation crew shows up with your replacement windows. Renewal by Andersen is excellent in keeping the customer informed from the start of the process to the final installation. We had a crew of 5 that took 2 days for 10 windows. They were definitely top-notch and you could immediately tell they had been installing windows for quite some time. They were definitely prepared for any situation that came up during your window replacement. One window had evidence of past termite infestation. The wood had to be replaced before the installation of our new window. I generally keep an infrared space heater in that room because of all the 5 bay windows. After our new windows were installed, WOW no heat loss. The room no longer felt cooler than the rest of the house. The windows look fantastic. The outside screens are virtually invisible. We love our new windows. You won't be disappointed!!"

"Every employee I have met in this company has been very kind and nice to speak with (even when I'm out of town and have to tell them I'm waay out of their zone for promotions lol!) Customizing the front door was fun, and I'm very happy with the end result of a brand new door frame that is sealed well and closes so quietly and smoothly! The frosted glass window panels top to bottom really let in an awesome amount of natural light. The manufacturing process went well with lots of updates along the way, and the salesperson was able to answer every question I had about financing. Can't wait to start upgrading the windows next! As a first time homebuyer I feel very secure in knowing I can call the company and they will make sure their product stays up to their quality standards. They are going to help this 105 year old house stand strong for another 100!"
