QUESTION:   Young millennial couple from DC, 20001 asks? Can my partner and I do this type of project over a weekend? 
 

ANSWER:  Jamb liner kits made of vinyl provide fully weatherstripped channels for old sashes to ride in. These replacement jambs, [carroer tracks] give the window a heat-loss efficiency equal to many double-glazed replacement windows. The new replacement jamb-liners have weatherstripped tracks that fit old window sashes. See the [manufacturer listings] of your jamb liners. There are specific instructions about measuring for the liner - or just email us: Info@windowpartsdoorparts.com

 
ANSWERS:  Old, Marvin double-hung windows - can be the largest source of drafts and energy loss in your older home if built before 1980's. Replacing even a modest Marvin double-hung window may cost as much as $1250, but it can be renovated for a fraction of the cost using a jamb liner or new jamb carrier track system. Years of opening and closing, the settling of the house and effects of the weather take their toll on a window, the wood sashes, the weatherstrip parts, the jamb balances, the meeting rail weatherstripping, bottom stile and sill stop seals and more. Although these damages were done to the windows over years - the renovations take only a couple of hours per window. SEE OUR YOUTUBE VIDEO CHANNEL - https://www.youtube.com/user/wefixitusa
