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.
Here are mistakes good window installers don’t make.
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.
