Patio & Sliding Doors

Patio doors are a large opening, which makes proper sealing essential in our climate. We install with quality weatherstripping and careful flashing so your new door keeps the cold out and the comfort in.

No more standing near the slider in winter and feeling the draft.

If your current door is sticking, drafty, or fogged, you may not need a full replacement. We repair worn rollers, damaged tracks, failed glass units, torn screens, and faulty hardware.

Often a targeted repair restores smooth, secure operation for a fraction of the cost of a new door.

A patio door has to do two things at once in our climate. It needs to open your home to the deck, patio, and yard during our beautiful summers, and it needs to seal up tight against the cold the rest of the year.

The patio doors we install are built for exactly that balance, with smooth operation for everyday use and insulated, well-sealed construction that keeps winter where it belongs.

Whether you are hosting on the deck in July or watching the snow fall in January, your patio door performs beautifully through every Northland season.

A patio door is more than the panels and glass. Quality screens let you enjoy the breeze without the bugs, solid locks keep you secure, and the right handles make daily use a pleasure.

We offer the screens, hardware, and accessories that round out your patio door, and we make sure every component is installed and adjusted to work smoothly together.

Patio doors come in many sizes and configurations, from standard two-panel sliders to wide multi-panel systems that open most of a wall. The right choice depends on your opening, the look you want, and how you use the space.

We measure carefully and walk you through the options so your new door fits the opening perfectly and suits the way you live, whether that is quiet everyday use or opening up the whole space for entertaining.

Patio doors stay trouble-free with a little routine care. Keeping the track clean and free of debris is the single most important thing you can do, since grit in the track is the most common cause of hard sliding and premature roller wear.

We show you how to clean the track, care for the glass, and keep the weatherstripping in good shape so your door glides smoothly for years.

Many patio door headaches trace back to poor installation. A door that is not level will not slide smoothly or seal evenly, and a poorly flashed opening will leak air and water.

Our installers set every door correctly and seal the opening properly, which prevents the drafts, sticking, and water issues that plague so many older patio doors. Doing it right the first time saves you repairs down the road.

Every project we complete is backed by both manufacturer warranties on the products and our own workmanship guarantee on the installation. That two-layer protection means you are covered for both the materials and the labor behind them.

As a local company that has served the Northland for generations, we are not going anywhere. If something ever needs attention, we are right here to make it right, which is the kind of accountability you simply do not get from a distant national chain.

Getting started is easy and there is no obligation. When you reach out, we schedule a convenient time to look at your project, take measurements, and talk through your goals and budget.

You receive a clear, written estimate that spells out exactly what is included, with no pressure and no surprise charges later. We would rather earn your business with honesty and good work than push you into a decision, so take all the time you need to decide.

When you hire Superior Glass, you are working with neighbors who know the Northland, understand our climate, and care about their reputation in the community. We answer the phone, show up when we say we will, and treat your home or business with respect.

Decades of repeat customers and referrals are the foundation of our business. That only happens when you consistently do right by people, and it is exactly how we intend to keep operating.
