Our team brings expert craftsmanship to everything from simple retrofits to complex structural tie-ins, and we’re the ones you call when things get tricky: rot repair, out-of-square openings, and clean siding integration. With flexible payment methods and financing options available, we make high-quality work easier to move forward on.

Frequently Asked Questions
How long does window replacement take?
It depends on the number of windows and project complexity. Most 10–15 window replacement projects take 3–7 days, factoring in access, trim work, and weather conditions.
Can you repair dry rot you find?
Yes. As a structural-repair general contractor, Pinnacle Contractors repairs damaged framing and sheathing before installing new windows to ensure long-term performance.
What brands do you install?
We work with leading manufacturers and recommend window lines that align with your goals, budget, and home style. Preferred brands include Milgard, Pella, and Ply Gem.
Will my home be protected during install?
Yes. We protect interiors with floor and wall coverings and safeguard exteriors using plastic masking and, when needed, temporary plywood. Landscape protection and thorough cleanup are part of every project.
Do you handle permits?
Yes. We manage permits for new window openings, structural modifications, and egress windows, coordinating engineering when required.
What glazing should I choose for Portland’s climate?
We typically recommend Low-E, argon-filled, double-pane energy-efficient windows. Final glazing selections are made case-by-case based on comfort, efficiency goals, and budget.
Do you offer financing and multiple ways to pay?
Yes. We offer financing options including 0% interest for 18 months on approved credit, and accept cash, check, card, ACH, and PayPal.
