Full-Home Window Replacement: Timeline and How Quotes Work

What to expect from order to install, and why quotes differ.

Replacement window in a Burlington home

Homeowners in Burlington usually want two answers: how long from the day they say yes until the new windows are in, and why one quote sits thousands of dollars away from the next. Neither answer is a single number for every house.

The Door Centre does window replacement for homes in Burlington, Oakville, Milton, Hamilton, Mississauga, Toronto, and Grimsby. From the day the order is placed to the day we install, a typical project takes about 6 to 10 weeks. That is the usual range, not a promise that every colour, every glass package, and every season lands on the same week.

What the 6 to 10 weeks includes

The clock people care about starts when selections are finished and the order goes to the factory, not when you first call. Measuring, choosing glass, and signing off on a written quote happen before that clock.

Once the order is in, the windows are built to your openings. They are not a stack of stock sizes waiting in a back room. Vinyl windows in a common white or a standard size can move faster than a less common exterior colour, a special grille, or a triple-pane package. We will tell you the build time we are hearing when you order, not the short end of the range by default.

Weather, site access, and a change of mind after the order is placed are the other movers. Changing a colour or glass package, or adding a patio door or entry door after the order, is the usual way a shorter job becomes a longer one.

What happens between the first call and install day

A clean project moves through the same steps. Skipping one of them is how quotes look cheap and installs go sideways.

  1. The first conversation. You tell us how many openings, which rooms are uncomfortable, and whether entry doors or patio doors belong on the same visit. Photos help. They do not replace a measure.
  2. The site measure. We look at each opening, the frame, and the interior and exterior finish. A bay and a basement hopper are not the same unit of work. Window installation in Oakville, Milton, and Hamilton is measured the same way as a Burlington house.
  3. The written quote. Every opening is listed with the window type, the frame, the glass package, the colour, and the install work that is included. If something is not on the page, it is not in the price.
  4. Your selections. Grilles, hardware colour, glass (double pane or triple pane), and any door choices get locked. This is the moment to ask about energy efficient windows room by room, not to apply one label to the whole house.
  5. The order. Lead time starts. You get a realistic window, inside that typical 6 to 10 weeks, based on what was actually ordered.
  6. Scheduling. We book the install when the product is on the way, not months before it exists. Someone needs to be home. Pets, alarms, and a clear path to the windows are part of the day going well.
  7. Installation and a walkthrough. Old windows come out, new ones go in, and we check operation and the visible finish with you. Crew time depends on the opening count and the old frames. That is written on the quote, not assumed as one day for every house.

If you are pursuing a rebate that requires an energy assessment before any removal, that assessment sits in front of step 6. It does not shrink the factory time. Mention it at step 1.

Why two window replacement quotes in Burlington rarely match

A lower total is not a better price until the pages describe the same work. Line the quotes up and check:

  • How many openings, and whether a garden door, a sidelite, or a fixed panel was left off one of them.
  • Double pane versus triple pane, and whether the low-e coating and gas fill are named.
  • Vinyl windows versus another frame, and the exterior colour.
  • Who handles exterior capping, interior trim, and hauling away the old windows. If a quote is silent, ask. Silence is not inclusion.
  • Whether the price is supply only or supply and installation. Those are different businesses.
  • Tax, and whether a deposit schedule is written down.

Compare complete pages, not the shortest total. Doors in Burlington belong on their own lines. Folding an entry door into "windows, approximately" is how door installation gets forgotten until the crew is in the driveway.

What moves a project through the $15,000 to $30,000+ band

For a full-home window replacement, many projects land roughly between $15,000 and $30,000 or more. Use that as a planning band only. Your number comes from the measure.

What pushes it:

  • More openings, or fewer but very large ones. A handful of big Great Room windows can pass a house full of small bedroom units.
  • Triple pane on the cold walls instead of double pane everywhere.
  • Specialty shapes, bay and bow windows, and coloured exteriors.
  • Frames that are rotten, out of square, or buried in old interior finishes. The glass price did not change. The labour did.
  • Patio doors added to the same order. A slider or a hinged patio door is not a slightly wider window.
  • An entry door and sidelites added because the front elevation is part of the same comfort problem.

Do not price your house from a neighbour's. A Burlington bungalow and a newer Milton two-storey are not the same quote. Hamilton, Mississauga, Toronto, and Grimsby, the other Greater Toronto Area communities we serve along with Halton, work the same way: the measure sets the number.

How to make the quote easy to approve

You can shorten the back-and-forth without rushing the order.

  • Count the openings before we arrive, including the side door and the basement.
  • Note which rooms draft, which glass is fogged between the panes, and which windows are hard to lock.
  • Decide whether the entry door and patio doors are in or out of this project. "Maybe later" is fine if it is said out loud.
  • Ask which product and labour coverage is in writing, and read the warranties page against the quote so the two match. We will not summarize that coverage as a slogan in place of the document.
  • If budget is tight, ask what the worst rooms cost versus the whole house. Leaving rooms off by accident is not a plan.

Ask us about current rebates & financing. Neither one changes the 6 to 10 week build or which glass you ordered. Settle both before you sign.
