How to Mensurate for Replacement Windows
You tin can supervene upon windows in just a few hours each, but first, you accept to get accurate measurements to society the new ones. It's like shooting fish in a barrel to measure the crude opening width and height once you lot remove the wood trim. But many DIYers make the mistake of non getting a precise depth measurement. If the window frame doesn't sit affluent with the wall, you'll have to airplane and sand the window frame or thicken the jamb depth with furring strips. That turns a relatively like shooting fish in a barrel task into an all-24-hour interval thing. And then take your time and use a ruler to get the correct depth.
Mensurate the width between the side jambs at the acme, middle and lesser and record the smallest measurement. Measure all the fashion to the jamb, not the blind stop or parting terminate (see Fig. A). Now mensurate the pinnacle from the elevation jamb to the sill (run into Fig. A). Measure both sides and the middle and record the smallest measurement. Finally, determine the sill angle and specify this when you social club a sash replacement kit to make sure the jamb liners fit tight to the sill. This stride isn't necessary for ordering forest or vinyl replacement inserts.
Your objective is to buy a window that fits inside that opening. If yous don't, yous'll accept to make the opening smaller, or worse, enlarge the opening to fit the new window. And that also means reworking all the outside trim, siding and interior wall surfaces. Take all of these numbers with you when y'all become shopping, and know that y'all can custom-guild odd sizes if no stock sizes fit your opening.
Step 3
Replacement Inserts or Sash Replacement Kits?
Both the sash replacement kit and the wood or vinyl replacement insert mountain inside your existing window jamb, in the place that was occupied by the onetime sash. They both fit in the infinite between the exterior terminate, called the blind stop, and the removable interior stop (see Fig. A). The sash replacement kit is designed to replace the sash in double-hung windows merely. Wood or vinyl replacement inserts, on the other hand, are cocky-contained units with their own jamb and sash, and can, therefore, exist slid into virtually any type of window jamb. They are bachelor as double-hung, sliding or casement-fashion windows.
Step four
Replacement Window Insert
Selection ane: Wood or vinyl replacement inserts
For a maintenance-complimentary window that doesn't require any painting or staining, consider vinyl replacement windows. Replacement window inserts tilt into the existing frame and are pre-hung in a frame. Some companies fifty-fifty make a simulated wood grain interior. Since woods or vinyl replacement inserts have their own jamb, they can be installed in window jambs that are slightly out of square. Ask your window dealer for help measuring, though, since you'll have to downsize the window slightly to fit.
Shopping for replacement windows is a little trickier than buying sash kits because the quality of the windows varies dramatically and many are bachelor only to contractors. Make sure to audit and operate an bodily working model of the window before you order. Expect closely at details like the locking arrangement, weatherstripping, and sash and frame joints. Then consider the overall appearance. Some windows, like ours, have narrow vinyl sash parts that permit more than light and a better view than windows with wide sash frames.
Step 5
Sash Replacement Kit
Selection two: Double-hung sash replacement kits
If you lot want to retain the authentic wood expect of your former double-hung windows, sash replacement kits are the all-time pick. Sash replacement kits have 5 parts and fit into the existing window. Yous can club the sashes with grilles to match the rest of the windows in your house and paint or stain the wood. (You can choose grilles that either snap-in or are glued to the glass.) Only your old window jamb must be square and rot-gratuitous. Measure out diagonally. If the diagonal measurements differ by more i/two in., the new sash won't seal properly and you should replace the window or use a vinyl replacement window instead.
Double-hung sash replacement kits consist of two new wood window sashes, two vinyl jamb liners and installation hardware. Features like free energy-efficient low-E drinking glass, fake divided lites and maintenance-free outside cladding are available for an extra cost. Contact the manufacturer for more data almost options and to find out where to guild windows in your area.

Contact your public health department for information on how to collect samples and where to send them. Do-it-yourself lead testing kits are besides available at dwelling centers and hardware stores.
Step 7
Gently Pry off the Interior Stops
First your replacement insert installation by removing the interior finish, sash and parting cease. Pry confronting a stiff putty knife to protect the wood. To minimize paint chipping on painted windows, score the joint betwixt the window frame and finish with a utility knife before prying off the end. Pull the nails through the behind of the stop with a nail nipper or pliers.
The parting stop is usually caked with pigment and difficult to remove. Utilize pliers to break out the lower section. If the upper sash is stuck, pry or break out the upper section of departing finish with a chisel. If your windows take spring balances or metal jamb liners rather than sash weights similar ours, start by removing the interior stops. Then look for the screws or nails that secure the sash hardware and remove them. The goal is to remove all hardware dorsum to the blind stops.
Footstep eight
Test the Fit
Sideslip the new window insert into identify to make sure it fits. You don't have to worry about dinging upwardly the jamb and sill considering they'll be covered. If your window has a sash weight cavity, stuff it with insulation. Then remove the window insert and lay a dewdrop of polyurethane window and door caulk along the inside of the blind terminate and the behind of the window stool.
Stride 9
Place the Window
Rest the bottom of the replacement window on the sill and tilt the window into place against the bullheaded stop. If your window includes a head expander, position it over the top of the jamb first. Press the window tight against the caulked bullheaded stop.
Step 10
Fasten the Window
Your wood or vinyl replacement insert will exist slightly smaller than the window jamb opening to allow for shimming. The key to a window that operates smoothly and seals properly is getting the frame perfectly square and the sides straight. Loosely fasten the window into the frame with partially driven screws in the lower left and upper right corners. Don't be afraid to remove the screws and readjust the window in the opening if necessary.
Step 11
Check for Square
Close and lock the sash. Measure diagonally across the new window. Slide shims behind the spiral holes in the 4 corners and conform them until the diagonal measurements from reverse corners are equal. Drive screws through the upper left and lower right spiral holes..
Step 12
Plumb the Window
In addition to checking the window by measuring the diagonals, open and close the sashes to make sure the tops and bottoms are parallel with the sill and top jamb and that the tiptop and lesser sashes are parallel to each other where they encounter in the middle. Concord a level confronting the side jamb and slide wood shims behind each remaining screw pigsty until the side jamb of the window is directly. Snug upwards all of the screws and check to make sure the sashes slide hands and marshal perfectly where they meet in the middle. Be conscientious; overtightening the screws could warp the vinyl jamb. Cut off the shims with a sharp utility knife.
Step 13
Reinstall the Trim
Replace the interior stops and nail them in identify with 4d finish nails.
Step 14
Insulate
Stuff fiberglass insulation in the gap under the sill of the new vinyl window. Measure the size of the gap and cutting the vinyl filler strip to fit. Use a precipitous utility knife and straightedge or tin snips to cutting the vinyl. Press the filler into place.
Step 15
Caulk
Caulk the articulation between the new window and the blind stop and between the windowsill and filler strip using window and door caulk.
Step 16
Installing Double-Hung Sash Kits
The toughest part of sash replacement is tearing out the one-time window. You have to pry off the stop (carefully for reuse) and the parting finish (which you can discard). You tin either nail or screw the new liner clips in place. We chose screws because driving nails tin can be hard in old window jambs.
Step 17
Determine the Bottom Angle of the Sash
Marshal the border of a heavy slice of newspaper with the window stop and fold the bottom to match the bending of the sill.
Step 18
Figure B: Find the Sill Angle
Lay a protractor on the folded paper to determine the bending. And so mensurate the interior height and width of the window frame. Utilize these measurements to order your sash replacement kit.
Pace nineteen
Remove the Lower Sash
Remove the lower sash and cut the sash cords. If your window has weatherstripping or hardware other than sash cords, pry out or unscrew these to remove the sash.
Step 20
Remove the Parting Stop
Pull or pry the departing cease from the groove in the window frame and discard information technology. Remove the top sash, cut the sash cords and accept out the sash weight pulleys. Remove the sash weight comprehend and weights. Stuff the crenel with fiberglass insulation.
Step 21
Attach Jamb Liner Clips
You tin can either nail or screw the new liner clips in place. We chose screws considering driving nails can be difficult in old window jambs. Spiral the jamb liner clips to the jamb with No. 6 ten 3/iv-in. pan head screws. Position clips nearly four in. from the top and bottom and distribute the remaining clips evenly between them. Brand sure to get out a one/16-in. space betwixt the clips and the bullheaded cease to allow space for the jamb liner to slide in.
Step 22
Place Jamb Liners
Snap jamb liners over the metal clips after installing the sash stops and gaskets according to the instructions included with your window. Align the jamb liner so its outside edge fits between the blind stop and the metal clips. If your jamb liner has a vinyl flap facing the outside, make sure it lays over the bullheaded stop. Press firmly over each prune location until you hear or feel the liner snap onto the clips.
Step 23
Add Summit Departing Stop
Slip the new parting cease into the groove in the height jamb with the weather-stripped border facing the outside. Drill 1/xvi-in. pilot holes and nail the terminate in place with iii 4d end nails. Replace the forest interior stops on the sides and top of the window and boom them in place with 4d finish nails.
Step 24
Position the Sash Lifts
Slide the sash lifts down to within nearly 10 in. of the windowsill. Press downwardly firmly with a flat-blade screwdriver. Twist the screwdriver slightly from horizontal to slide the lifts. So twist back to horizontal to engage the lifts in their new locations.
Circumspection: Release pressure slowly to make certain the clips are engaged before you remove the screwdriver completely.
Step 25
Install the Sash
Concur the top sash with the outside facing upwardly and the metal cams away from you lot. Tilt the sash a picayune and align the metallic pivots with the slots in the jamb liner closest to the exterior. Make certain the pivots are above the sash lifts. Tilt upwardly the sash and printing outward on the jamb liner while you snap the top of the sash into identify between the jamb liners. Slide the sash down until the metallic cams contact the sash lifts. Echo the process on the lower sash. If you take problem pushing in the sash subsequently y'all tilt it up, endeavor working with ane side at a fourth dimension.
