Installation cost covers the unit, the labour, flashing, sealant, interior trim and disposal of the old unit. The standard unit is one window or one door.<\/p>\n
Excluded is structural repair, framing modification and paint or finish work, unless the quote says otherwise.<\/p>\n
Flashing and sealant<\/strong> run $20 to $50 per opening. Trim runs $30 to $100, and disposal runs $10 to $30.<\/p>\n A typical four-window, one-door project installs five units. Five is a manageable test job.<\/p>\n Per-unit pricing normalizes for size.<\/strong> A five-unit job and a twenty-unit job compare honestly.<\/p>\n Where does glass sit on that list? Replacing the glass in a window<\/a> prices as its own job, and a sound frame keeps it far below a full replacement.<\/p>\n The performance spec moves the unit price before anything else. Window energy ratings<\/a> decide which grade you are buying, so read them before comparing quotes.<\/p>\n A single window lands around $310 to $1,680 installed.<\/strong> A single door lands around $610 to $2,580.<\/p>\n Window pricing splits two ways. One is swapping the glass inside a sound frame. The other is replacing the whole window.<\/p>\n Choosing between double-hung and casement<\/a> changes the hardware and the price, because the operation is part of the unit.<\/p>\n A standard vinyl double-hung window runs about $310 to $1,000 installed.<\/strong> A casement with its crank hardware runs about $350 to $1,200.<\/p>\n A single-hung window<\/strong> runs about $280 to $800 installed. A sliding glass door runs about $800 to $2,500.<\/p>\n Entry doors price by skin. Steel<\/strong> runs about $600 to $1,500 installed, fiberglass<\/strong> about $800 to $2,200, and wood about $1,000 to $3,000.<\/p>\n Interior doors are a different trade. The labour is mostly carpentry, because there is no flashing and no weatherstrip to install.<\/p>\n A prehung interior door runs $235 to $1,110 for a DIY install<\/strong> and $385 to $1,610 professionally. A slab is cheaper, because the frame stays.<\/p>\n Installing a prehung interior door<\/a> and installing a door slab<\/a> both show exactly what that labour line buys.<\/p>\n Hourly rates run $50 to $75.<\/strong> One unit takes roughly two hours to install.<\/p>\n The published estimates genuinely conflict.<\/strong> Here is the spread, source by source, because the conflict is the useful part.<\/p>\n Bob Vila puts replacing glass in a window at $180 to $411 typically<\/strong>, with a national average of $281, and individual replacements as little as $100 or as much as $700.<\/p>\n This Old House puts the same job at $300 to $880 per window installed, with a $375 average, and puts reglazing at $250 to $500 per window.<\/p>\n Fixr matches that band, $300 to $880 including labour, with most homeowners spending about $375 on clear glass in a standard 30 by 36 inch double-pane window.<\/p>\n HomeAdvisor instead puts professional replacement at $181 to $414 per window<\/strong>, averaging $285, with float glass at $150 to $400 and tempered at $200 to $600.<\/p>\n A frame swap adds $180 to $600.<\/strong> That is where the two bands split.<\/p>\n Why the gap? Scope is defined differently.<\/strong> Some sources price a glass swap in a sound frame. Others price a full window.<\/p>\n Glass type, thickness, size, access and local labour rates do the rest. No source publishes its sample, so treat each figure as a band, not a price list.<\/p>\n HomeAdvisor puts a new window installation project at an average of $7,348<\/strong>, with most jobs between $3,436 and $11,839.<\/p>\n Fixr places most installed windows between $300 and $2,200, averaging $1,047 for one replacement window, and puts a ten to fifteen window project at $6,500 to $18,650.<\/p>\n This Old House reports $517 per installed window<\/strong> and $7,183 per project, from a survey of 1,000 window customers.<\/p>\n Which number is right? None, and all of them. Five scopes, five answers.<\/strong> Read the scope first.<\/p>\n Per-window figures cover one opening at a time. Project figures bundle many openings, plus whatever the house threw at the crew.<\/p>\n Modernize reports a $1,047 national average per window across more than a million homeowner projects. A single replacement window is the cheapest test of how a contractor prices.<\/p>\n Before the unit, the opening gets inspected. That inspection is where quotes diverge.<\/strong><\/p>\n Rough opening condition<\/strong> moves the quote first. Rot, frame damage or an out-of-square opening needs repair before the new unit goes in, and that adds $200 to $600 per opening.<\/p>\n Then floor level. First-story installations are standard. Second-story access<\/strong> needs a lift and adds $100 to $300 per unit.<\/p>\n Then trim. Basic paint-grade casing is usually included. Custom millwork<\/strong> adds $100 to $400 per opening. Stained trim lands in the same band.<\/p>\n None of those show up in a per-unit price. A quote that omits them is quoting the easy version of your house.<\/p>\n For a door, labour buys the fit.<\/strong> Hinge placement, the reveal, the latch meeting the strike. Get one wrong, and the door never closes right.<\/p>\n For a window it buys flashing and drainage.<\/strong> Those are the two things that fail later, not the glass.<\/p>\n A buyable quote lists the unit, the size, the material, the grade, the labour per unit, the flashing and sealant, the interior trim, the disposal and the warranty.<\/p>\n Walk away from any quote that says replace all windows and doors<\/strong> with no breakdown. That is not a price, it is a shrug.<\/p>\n Then check the five numbers that decide a quote<\/strong>: how many units, what material and grade, what labour rate, what flashing and trim allowance, and what disposal costs.<\/p>\n Those five numbers explain every figure above.<\/p>\n The wider map lives in the windows and doors guide<\/a>, and DIY versus professional door installation<\/a> is where the skill question gets decided honestly.<\/p>\n Next step: get the unit and the labour priced separately, then compare two quotes line by line. That is how to choose a fair installer before you commit.<\/p>\n","protected":false},"excerpt":{"rendered":" Window and door installation cost comes down to two lines: the unit and the labour, and every quote should show both.
