Let’s Talk About What Makes an Installation More Difficult
Have you ever wondered why two companies can quote the same windows or doors, yet the prices are miles apart? It’s not always about markup or hourly rates—it often comes down to how difficult the installation will be, and how that affects the amount of labor required.
Let’s talk about why window and door quotes vary for Phoenix homes.
Most reputable window and door companies can recognize when a project will be more labor-intensive—after all, they’ve done hundreds, even thousands of installations. But how a salesperson estimates and prices that labor can still vary. Everything from your home’s construction and window frame depth to how easy it is to access each opening can change how long the job takes, how many installers are needed, and what materials are required.
Some companies build that extra labor into their quote from the start, while others underprice it to look more competitive—leaving room for delays, shortcuts, or surprise add-ons later. Experienced teams, on the other hand, tend to quote more realistically, sometimes including a small buffer for problem-solving if the project turns out trickier than expected.
Skill level matters, too. Certified installers not only estimate the difficulty more accurately, but their training helps them execute the work faster and with fewer surprises along the way. Their speed and experience often save homeowners money, while ensuring the craftsmanship holds up for decades.
At DunRite, those details are part of every estimate when selling window and door products in the Phoenix metro area. The goal is simple: quote the job honestly, plan for the real amount of labor needed, and complete every installation with workmanship that lasts.
Here are some of the key factors that influence your final quote:
- Type of installation method – retrofit vs. full nail-fin cutback
- Material and frame depth – vinyl, fiberglass, aluminum, or wood
- Home construction and access – stucco, block, multi-story, or tight spaces
Hidden issues like dry rot, insect or water damage and structural surprises can also impact the final amount you pay, but if it’s something that can’t be seen until a wall is opened or the old window removed, then it wouldn’t show up in your estimate. It’s an added cost you’d have to decide on when the issue is discovered.
Let’s unpack how each of these affects cost—and why the cheapest quote isn’t always the best value in the long run.
Why Installation Complexity Changes the Price
Homeowners often assume product pricing drives the total cost of a project. In reality, installation labor can be just as significant—and often varies the most from one company to another.
As DunRite owner Sal Sucato explains, “If we’re installing something like an aluminum-clad, pre-stained wood window, it’s far more labor-intensive than a basic vinyl product. We have to order trim, jamb extensions, match stains, and work around architectural details. Every one of those steps adds time.”
Installation isn’t one-size-fits-all. Every home is built differently, and what seems like a simple window swap on paper can reveal unique challenges once the old frame comes out. Labor intensity, accessibility, product material, and installation method all factor into your quote.
What Makes a Window Installation More Complex
1. Construction Type and Home Age
Older homes or those with plaster interiors take longer to work on than modern block or frame houses. According to Sal, “A block house is by far the easiest. Those old 1950s plaster homes? They’re the hardest.”
Age also introduces potential complications—like discovering lead paint or outdated materials. DunRite is EPA-certified for lead renovations, but those projects require full containment, HEPA filtration, and protective gear. It’s safe, but adds cost and time.
2. Installation Method
There are two main approaches:
- Retrofit installation (also called “jump frame”): the new window fits into the existing frame. It’s faster, cleaner, and more affordable.
- Stucco cutback with full nail-fin installation: the old frame is removed entirely, and stucco is cut back to allow new flashing and sealing. This method provides a more thorough replacement but is significantly more labor-intensive.
Sal sums it up simply: “A stucco cutback is by far the more expensive installation because there are more trades involved—stucco work, flashing, sealing—it’s a lot more people and labor hours.”
3. Frame Material and Depth
Different materials come with different frame thicknesses. Fiberglass and wood windows tend to be deeper than vinyl, which means installers may need to modify the interior drywall or trim for a proper fit.
“If a homeowner upgrades from old aluminum to an aluminum-clad wood window, for example,” Sal explains, “we may have to remove drywall and trim the opening flush to the inside like a door. That’s a substantial amount of extra labor.”
4. Access and Size
Larger windows, second-story installations, or homes built into slopes often require scaffolding or boom lifts—both of which raise labor costs. A simple patio window on the ground floor might take an hour or two, while the same window on a second story with difficult access could take most of a day.
5. Hidden Surprises: Dry Rot, Termites, or Water Damage
While rare, hidden damage under the old frame can derail an otherwise straightforward project. “If we find something structurally unsound,” Sal notes, “the homeowner can pause the job and bring in a general contractor to repair it. It doesn’t happen often, but when it does, it adds time.”
What Makes a Door Installation More Complex
1. Product Type and Precision Requirements
Doors vary dramatically in installation difficulty, too. Bi-fold and multi-slide systems demand perfect alignment across multiple panels. Even small misalignments can prevent smooth operation.
“Bi-fold doors are the most labor-intensive,” says Sal. “They have to be installed perfectly level and square. A multi-slide door is next in difficulty, then hinged or standard sliding doors.”
A pre-finished or factory-stained door also adds complexity. Every nail hole must be plugged, and cut ends have to be hand-stained or painted to match—work that isn’t necessary with unfinished products the owner (or a handyman) will paint.
2. Material Weight and Size
Steel and solid wood doors are heavy, requiring extra crew members or equipment to move them safely. Oversized or pivot doors also take more time and precision. As Sal puts it, “A pivot door is always going to be more expensive to install—it’s a totally different process.” And if you are having a big multislide or multifold patio door installed? Be prepared for substantial labor costs… especially if it requires construction or fortification where the doors will hang.
3. Existing Conditions
Older door frames can be uneven, warped, or out of square. Flooring transitions, stucco edges, or trim details may all need modification. DunRite typically builds this into the estimate, but in rare cases—like discovering electrical wiring where it should not be (for example, inside a window opening)—they’ll pause to alert the homeowner. They’ll only be able to proceed with installation after the correction has been made.
And if something minor pops up during the job? “We usually just absorb those costs,” Sal admits. “That’s part of what sets us apart. We’d rather fix it and make it right than surprise the customer with another invoice.”
It’s not a policy you’ll find everywhere. Many companies would pass along the added cost, but DunRite prefers to take responsibility for the little things. It’s part of maintaining the workmanship and trust the team has built its reputation on.
The Role of Expertise in Labor Costs
DunRite invests heavily in training its team, sending installers through the Certified InstallationMasters program—a national AAMA certification that teaches best practices for proper installation, along with training from the specific manufacturers whose products they install. This ensures every installer uses methods that maintain product warranties and long-term performance.
But it’s not just about training; it’s about experience. Many of DunRite’s installers have been with the company for decades. They’ve mastered the nuances of different materials, home styles, and construction methods unique to Arizona homes. That kind of longevity builds deep craftsmanship and consistency you won’t find with fly-by-night contractors or revolving crews.
“We pay more for our guys because they’re top-tier installers,” Sal explains. “That does affect the overall price, but it also means the job’s done right. You get what you pay for.”
Expert installers work more efficiently, handle complex projects correctly the first time, and know how to seal, flash, and align products for maximum longevity. That experience often saves homeowners from costly callbacks or repairs later on. It’s done well the first time.
Comparing Quotes Fairly
When homeowners gather multiple estimates, it’s easy to assume a lower number means better value. In reality, quotes often differ because of what’s included—or excluded. One may be for a retrofit install to save money, another for a full nail-fin cutback to ensure the stucco is flawless. Some companies rely on temporary crews or underpaid labor, while others, like DunRite, use seasoned, certified professionals.
Sal’s advice? “Choose the company you’re most comfortable with—someone you trust to work on your home and stand behind the job if there’s ever an issue.”
Authentic online reviews can help homeowners gauge that trust factor. Look for reviews mentioning workmanship, cleanliness, and responsiveness rather than just price.
Asking questions can sleuth out details you might’ve otherwise missed, too. It’s important to not assume every quote is apples-to-apples with another… even if it’s the same product.
Final Thoughts
Every home—and every installation—is different. Factors like access, frame material, and construction type all influence how much labor is involved and, ultimately, how much the project costs. But one constant remains: the skill of the installer determines the quality, longevity, and value of your investment.
At DunRite Windows & Doors, every project is handled by trained professionals who take pride in precision work and lasting results. It’s not always the cheapest bid—but it’s the one done right.
