Replacement Windows & Patio Doors in Oakland County, Michigan
Windows and patio doors do more than frame your view of the backyard. They control how warm your home stays in a Michigan January, how much your energy bill runs, and how easily you move between your living room and your deck. At Doors of Pontiac, we have been installing replacement windows, sliding patio doors, and French patio doors for Oakland County families since 1977. From our Waterford Township showroom on Highland Road, our factory-trained technicians deliver a clean, precise fit that seals out drafts and lasts for decades.
We are a family-owned and operated company, not an out-of-state call center reading from a script. That local ownership shows in how carefully we measure, insulate, and finish every opening. With 4.9 stars across more than 1,500 reviews, our neighbors trust us to get it right the first time. Whether you want to swap a single foggy window or replace a tired sliding door with a stunning French patio system, the process is simple: free estimate, in-home measure, professional install. Call 248-666-9777 to get started.
Replacement Windows Installed by Local Pros
Old, drafty windows are one of the biggest sources of wasted heat in an Oakland County home. Single-pane glass, failed seals that fog up between panes, and worn weatherstripping let your furnace work overtime all winter. Our replacement windows solve that with insulated double-pane and triple-pane glass, low-E coatings, and argon gas fills that hold warmth inside where you want it. We install double-hung, casement, sliding, bay, bow, picture, and garden windows to fit any room and any style.
A window is only as good as its installation. We square up the opening, set each unit level and plumb, insulate the gaps, and seal the exterior so wind-driven rain and snow drain away instead of rotting your framing. The result is a tight, quiet, energy-efficient window that operates smoothly for years. Ready to cut your drafts and your heating bill? Request your free estimate today.

Sliding Patio Doors
A sliding patio door is the workhorse of the backyard entrance: space-saving, easy to operate, and packed with glass to flood your room with natural light. Because the panels glide sideways rather than swinging, sliders are perfect for tight spots like a dining nook or a deck landing where a hinged door would get in the way. We install two-panel and three-panel sliding doors with smooth-rolling stainless hardware, adjustable rollers, and multi-point locks for security.
The difference between a slider that sticks and one that glides for 20 years is the install. We level the sill, set the track true, and seal the frame so the door rolls effortlessly and stays weathertight against Michigan cold. Insulated glass and quality weatherstripping keep the drafts out and the heat in. Upgrade your walkout with a patio door that works as good as it looks. Call 248-666-9777 to talk options.

French Patio Doors
When you want a showpiece entrance to the patio, nothing beats a French patio door. Wide swinging panels, elegant divided-light glass, and classic hardware turn a plain back wall into a focal point that lifts your whole home's character. We install both in-swing and out-swing French doors, single-active or double-active configurations, with optional sidelights to widen the opening and the view. It is the upgrade that makes a kitchen or great room feel twice as big.
French doors demand a precise, plumb install to swing true, latch cleanly, and seal tight, and that is exactly the detail-focused work we have delivered since 1977. We set the frame square, adjust the astragal and strike, and weatherproof the threshold so both panels close with an airtight, satisfying latch. Add decorative glass, grille patterns, and hardware finishes to match your style. Ask us to help you design the perfect French patio entrance.

Energy Efficiency Built for Michigan Winters
Oakland County windows and patio doors take a beating from sub-zero mornings, freeze-thaw swings, wind-driven snow, and road salt. That is why we focus on the details national chains skip: insulated glass units with low-E coatings and argon fills, thermally broken frames, continuous weatherstripping, and thresholds that drain water away from your framing. These are the same energy-efficiency choices that keep drafts out, cut your heating and cooling bills, and stop that cold-glass chill in the middle of winter.
An air-tight, well-insulated window or patio door also quiets road noise, prevents condensation and frost buildup, and protects your walls from moisture damage. We choose corrosion-resistant hardware and durable finishes that shrug off salt and humidity year after year. This Michigan-specific know-how comes from nearly 50 years of local installs, and it is exactly what an out-of-state installer cannot match. Ask us about the most energy-efficient options for your home.

FAQ — Replacement Windows & Patio Doors in Oakland County, Michigan
Should I choose a sliding or French patio door?
It comes down to space and style. Sliding doors save room because the panels glide sideways, making them ideal for tight spots and easy everyday use. French doors swing open for a wider, more elegant entrance and a classic look. We will help you weigh both during your free in-home estimate.
How energy-efficient are your replacement windows?
Very. We install insulated double-pane and triple-pane windows with low-E coatings and argon gas fills, set in thermally broken frames and sealed tight. These features cut drafts, lower your heating and cooling bills, and stand up to Michigan's freeze-thaw winters far better than old single-pane glass.
Can you replace just one window or door?
Absolutely. Whether you have a single foggy window with a failed seal or a tired sliding door to swap out, we handle jobs of any size. Many homeowners start with one problem opening and add more later. Call 248-666-9777 for a free estimate on any project, big or small.
Do you offer financing and warranties on windows and patio doors?
Yes. We offer financing options to keep your window or patio door project affordable and easy to budget, and every product is backed by manufacturer warranties plus our nearly 50-year local reputation.
