Spec the glass first
We compare available Low-E coatings, pane counts, spacers, and other glass options against room exposure and whole-unit performance ratings.
Pella · Partner
The Pella window comes second. The opening comes first.
Category i · Windows
Casement, double-hung, picture, awning, chosen for the opening.
Casements crank open and suit modern and Craftsman lines. Double-hungs read period-correct on Colonial and Federal homes. Picture windows hold a view without another sash line; sliders fit wide openings; awnings vent where a projecting sash would be in the way. Bay and bow windows add structure, trim, and a roof tie-in to the decision. We choose the operation room by room, then spec the glass.
Who installs them
Category ii · Entry & patio doors
The door is the seal and the hardware.
An entry door is judged on its weather sealing and security hardware. Pella's entry and patio line covers sliders, French swings, and multi-panel doors. The hinge side and swing get decided at the opening, before anything gets ordered.

Category iii · Specialty windows
Architectural shapes, not stock compromises.
Arched, half-round, octagonal, fixed picture, custom-bent geometry. Where the home's architecture leads, we shape the window to match instead of forcing the house into a stock rectangle. Black-frame packages, like the Spring Mill detail, change the whole read of an elevation.
See specialty workThe frame, sill, trim depth, and water path decide whether a Pella window belongs in the opening and can be installed correctly. As a Pella Partner, we inspect the opening before choosing the product.

Locke & Ladder is a Pella Partner
Partner access is useful. The opening still decides.
We can specify Pella operating windows, fixed windows, entry and patio doors, specialty shapes, and available glass packages. The proposal should identify the exact series, operation, glass, finish, installation method, trim scope, and current warranty terms—not rely on the partner badge as the specification.
What to specify in a Pella proposal
The product name is not the specification.
We document the qualifying specs
A whole-home replacement of 30-year-old windows for Timothy W. qualified for a Duke Energy window-update rebate. Programs change, and the utility decides eligibility; we document the proposed specifications so the homeowner can check the current program.
Impact-resistant where it earns it
Where impact resistance is being considered, the proposal should identify the exact product, tested rating, warranty terms, added cost, and which elevations receive it.
★★★★★
“We used Locke and Ladder for updating our 30+ year old windows. Jay and team did a fantastic job with the install. Noticeable improvement in energy efficiency and quietness. Bonus also with Duke Energy offering a window update rebate.”

“Within two days, the team replaced nearly every window in our home. Quality of the product and professional installation made a difference within minutes.”

★★★★★
“We chose Locke and Ladder after getting four bids. They were not the lowest bid, but the entire sales process was a leading reason why we chose them. Caleb did a very thorough job of explaining everything we needed to know about replacing a roof and doors and windows.”

The spread is openings and glass, not list price.
Our project price guide lists windows and doors at a typical project price of $20,000, with most projects falling between $8,000 and $35,000. Typical window pricing starts around $1,700 per opening. These are planning figures across brands and scope types, not Pella unit prices.
| Driver | Why the number moves |
|---|---|
| Opening count | A single-door swap and a whole-home 20-opening replacement are not the same project. Count is a primary driver of the total. |
| Glass package | Pane count, Low-E option, gas fill, spacer, impact rating, and unit size can change the price. Compare the exact package in the proposal. |
| Specialty shapes | Arched, half-round, and custom-bent geometry cost more than stock rectangles because they are cut to the opening. |
| Opening condition | Rot, bad trim depth, or a compromised water path found behind the existing window adds scope. We show it before we touch it. |
See the Cost & Scope Index for the full window-and-door breakdown.
FAQ
Pella
Is Locke & Ladder a Pella Partner?
Yes. We are a Pella Partner. The partner label does not replace opening inspection: we document frame condition, sill, trim depth, and water path before selecting the product.
What do you look at before recommending a window?
The opening: frame condition, sill, trim depth, water path, sightlines, and how the elevation reads from the street. The product comes after that. The job is to pair the right homeowner and house with the right window, not push a catalog answer into every opening.
What do window and door projects cost?
Our project price guide lists windows and doors at a typical project price of $20,000, with most projects falling between $8,000 and $35,000. Typical window pricing starts around $1,700 per opening. These are planning figures across brands and scope types, not Pella unit prices. See the Project Price Guide.
Who installs the windows once we sign?
Recent window and door reviews name Jay, Charles, and Joe. The proposal identifies the planned crew and schedule for the actual opening count and finish scope.
Do Pella windows qualify for Duke Energy rebates?
One whole-home replacement of 30-year-old windows for Timothy W. qualified for a Duke Energy rebate. Programs and eligibility can change; the utility determines qualification. We document the proposed specifications so the homeowner can check the current program.
Bring photos of the openings. We'll bring the catalog.
Send photos of the openings, a count of how many windows or doors, and any rebate or energy goals. We will compare the Pella options with the opening condition and then price the actual product and installation scope.
