What makes us different
Your job is installed by our dedicated install crew. We practice lead-safe installations, and our installer is EPA Lead-Safe certified (RRP) for work on homes built before 1978.
We pull the building permit for window and door installs.
We take them with us.
Once your job is signed, the price doesn’t change, except in extreme circumstances.
If we find rot on the frame where the new window sits, we fix it free of charge.
From order to install, depending on the product and any specialty shapes.
Most jobs are inserts. We only go full-frame when the old frame is damaged.
Windows and doors. Install-related problems, manufacturing defects and failures, plus accidental glass breakage. Transfers when you sell.
Castle’s top package is triple-pane with krypton, built to meet ENERGY STAR Northern-zone requirements.
*Except in extreme circumstances.
Materials
Every Castle window is vinyl that never needs painting, made to the size of your opening, with frames and sashes fusion-welded at the corners.

*ENERGY STAR Version 7.0 Northern-zone criteria for windows: U-factor ≤ 0.22 with SHGC ≥ 0.17 (or an equivalent-energy option of U-factor 0.23–0.26 with a higher SHGC), and air leakage ≤ 0.3 cfm/ft². Massachusetts is in the Northern zone. Sources: ENERGY STAR window criteria, climate zone map. ENERGY STAR certified options are available; ask which models are certified when we quote. Castle offers double-pane and triple-pane glass with argon or krypton gas fill. Every tier includes a triple-layer silver Low-E coating that blocks about 95% of the sun’s UV rays and much of its heat while still letting daylight through. Castle window frames and sashes are fusion-welded at the corners (heat-fused into one permanent joint instead of screwed together) and ordered with foam-filled frame and sash chambers. Your quote lists the exact package and its NFRC label numbers.
Installation
That’s our intent, and the reason we can offer the Castle Lifetime Guarantee. Many companies don’t say much about how they install. We do: each step, and why it matters.
Guarantee vs. warranty
They sound alike, but they are different promises. Here’s the plain-English difference.
| A typical product warranty | The Castle Lifetime Guarantee | |
|---|---|---|
| Who makes the promise | Usually the product manufacturer | Castle, the company that sold and installed it |
| What it covers | Often the product only, as limited by the fine print | The whole job: anything that goes wrong with the window or door, install-related or a manufacturing defect or failure |
| Labor to fix it | Many warranties leave labor out or limit it to a short period | Included |
| Accidental glass breakage | Often excluded or limited | Included |
| When you sell your home | Some transfer only with paperwork or a fee; some don’t transfer | Transfers to the new owner |
| Who you call | The manufacturer, then whoever will do the repair | Castle |
Warranty terms vary a lot from company to company, so always read the written document. ENERGY STAR’s buying tips point out that the product, the glass seal and the installation are often covered by separate warranties with different time periods, and that installation coverage is typically the shortest.[source]
Peace of mind
If anything goes wrong with a window or door we install, whether it’s install-related or a manufacturing defect or failure, the Castle Lifetime Guarantee covers it. That includes accidental glass breakage, and it transfers to the new owner if you sell your home.
