What Specialty & Custom Shapes Is Covered For
Covered under the same Alside Lifetime Limited Warranty as the corresponding product line.
Manufacturer terms are set by the manufacturer and can change. This reflects published coverage at the time of writing; the certificate we hand you at completion governs, and we register it in your name before we leave. See every warranty we offer →
Where Specialty & Custom Shapes Makes Sense
Older Pittsburgh homes where no two openings are the same dimension.
Our crews are factory trained and certified by the manufacturer. That matters more than the sticker on the glass: improper installation is the single most common reason a window warranty claim gets denied.
- Factory Trained & Certified Installers
- Lifetime Limited Warranty
- ENERGY STAR® Qualified Packages
- Custom Made to Your Opening
How Your Window Project Runs
- 01
In-home measure
Every opening measured individually to the sixteenth. Replacement windows are manufactured to your house, not ordered off a shelf.
- 02
Glass package selection
We walk through Low-E coatings, argon fill and spacer options and show you what each one actually does for a Pittsburgh winter and a July afternoon.
- 03
Manufacturing
Units are built at the factory, typically 3–5 weeks. We give you a real date, not a season.
- 04
Certified installation
Factory trained and certified installers set, shim, insulate, flash and trim each opening. Most homes are done in a day.
- 05
Warranty registration
Units registered in your name so the Lifetime Limited Warranty is on file before we leave.

We couldn’t be happier with the work done by Top Dog Exterior Remodeling. Tyler was fantastic at communicating throughout the entire process, coming by a couple of times to explain what the job would cover and making sure we were comfortable every step of the way. His team of professionals were detail-oriented, respectful, and highly skilled. They stuck to the timelines they promised and showed up exactly when they said they would—a h…
