WINDOW REPLACEMENT INSTRUCTIONS FOR
SINGLE-HUNG, DOUBLE-HUNG, CASEMENT, AWNING
INTO EXISTING CASEMENT FRAME USING FRAME SCREWS
These instructions were tested and developed for replacing windows in wood-frame wall
construction systems designed to manage moisture. This method of installation involves removing
the sash, frame stops and frame hardware from the existing window. The original window frame
will remain in place. If the existing window frame shows signs of water infiltration or is damaged
beyond repair, this method should not be followed and the entire existing window should
be removed. Installation recommendations for other types of wall construction, wall systems,
conditions, multiple windows or bow/bay windows, may be obtained from Pella Corporation or a
local Pella retailer. Building designs, construction methods, building materials, and site conditions
unique to your project may require an installation method different from these instructions and
additional care on your part. Determining the appropriate installation method is the responsibility
of you, your architect, or other construction professional.

Note: Single-hung: Raise the lower sash to access lower installation holes. Double-
hung: Lower the top sash to access the upper installation holes and raise the lower
sash to access the lower installation holes. Tilt the lower sash to the interior to access
the installation holes at the checkrail. Assistance from the interior is recommended for
this step.
5 INTERIOR SEAL
Caution: Ensure use of low pressure polyurethane window and door insulating foams
and strictly follow the foam manufacturer’s recommendations for application. Use of
high pressure foams or improper application of the foam may cause the window frame
to bow and hinder operation.
A. Apply insulating foam sealant. From the interior, insert
the nozzle of the applicator approximately 1" deep into
the space between the window and the rough opening
5A
and apply a 1" deep bead of foam. This will allow room
for expansion of the foam and will minimize squeeze
out. Apply sealant across interior surface of shims
to create a continuous seal. For windows with jamb
extensions installed, ensure the foam is placed between
the window frame and the rough opening, not between
the jamb extension and the rough opening. Follow
foam manufacturer's instructions.
Note: It may be necessary to squeeze the end of the tube with pliers to be able to
insert into the space between the window frame and the rough opening.
B. Check the window operation (vent units only) by

Note: If the window does not operate correctly,
check to make sure it is still plumb, level, square,
and the jambs are not bowed. If adjustments are
required, remove the foam with a serrated knife.
Adjust the shims and reapply the insulating foam
sealant.
Jamb plug
C. Insert jamb hole plugs (provided) into each screw hole for single-hung and double-hung
units.
Interior Finish or Trim:
The space between the new window and the existing window’s frame will need to be covered
with trim. There are many ways to accomplish this and each case can be unique. How this is
done will be the decision of the homeowner or window
installer. A few possibilities include using cove,
quarter round, or a stop moulding.

EXTERIOR
6 EXTERIOR SEAL
A. Insert backer rod into the space
around the window at the head and
jambs. This should provide at least
3/8" clearance between the backer rod
and the exterior face of the window.
6B
Note: Backer rod adds shape and
depth for the sealant line.
B. Place a bead of sealant at the jambs
and head between the existing
window frame and the replacement
window frame.
Download from Www.Somanuals.com. All Manuals Search And Download.
C. Begin the sill sealant bead 1/2" from one jamb, running it across the sill and stopping
1/2" from the opposite jamb. This 1/2" sealant gap on each side of the sill allows for
incidental water drainage.
D. Shape, tool, and clean excess sealant. When finished, the sealant should be the shape
of an hourglass.
Note: This method creates a more flexible sealant line capable of expanding and
contracting.
EXTERIOR FINISH OF EXISTING FRAME
Any exposed wood and flashing tape on the exterior needs to be
covered/protected. There are many ways to accomplish this, and
each case can be unique.
A few possibilities include:
a) Covering the existing trim with aluminum coil wrap/
frame expander.
b) Sanding, priming and painting to match existing trim.
c) Covering the exposed wood with a high quality exterior
grade sealant.
Note: The contractor/installer will determine how to finish
the exterior.

FINISH
The interior and exterior frame and sash are protected by a powder coat baked-on factory finish
that requires no painting. Clean this surface with mild soap and water. Stubborn stains and
deposits may be removed with mineral spirts. DO NOT use abrasives. DO NOT scrape or use tools
that might damage the surface.
Use of inappropriate solvents, brickwash or cleaning chemicals will cause adverse reactions with
window and door materials and voids the Limited Warranty.
CARE AND MAINTENANCE
Care and maintenance information is available by contacting your local Pella retailer. This
information is also available at www.pellaimpervia.com.

be designed and constructed to properly manage moisture. Pella Corporation is not responsible
for claims or damages caused by anticipated and unanticipated water infiltration; deficiencies in
building design, construction and maintenance; failure to install Pella® products in accordance
with Pella installation instructions; or the use of Pella products in wall systems which do not allow
for proper management of moisture within the wall systems. The determination of the suitability of
all building components, including the use of Pella products, as well as the design and installation
of flashing and sealing systems are the responsibility of the Buyer or User, the architect, contractor,
installer, or other construction professional and are not the responsibility of Pella.
Pella products should not be used in barrier wall systems which do not allow for proper
management of moisture within the wall systems, such as barrier Exterior Insulation and Finish
Systems, (EIFS) (also known as synthetic stucco) or other non-water managed systems. Except
in the states of California, New Mexico, Arizona, Nevada, Utah, and Colorado, Pella makes no
warranty of any kind and assumes no responsibility for Pella windows and doors installed in
barrier wall systems. In the states listed above, the installation of Pella products in barrier wall or
similar systems must be in accordance with Pella installation instructions.
