Common questions
How do I know when it’s time to replace my windows?
Common signs include drafts or cold spots near closed windows, fog or moisture between the panes, windows that stick or won’t lock, soft or rotting frames, and rising heating and cooling bills. If your windows are 20+ years old and showing any of these, it’s worth a free inspection. We’ll tell you honestly whether a repair will do or replacement makes sense.
How much do replacement windows cost?
It depends on how many windows you’re replacing, their sizes and the styles and options you choose. We give free written estimates after measuring in person, so you know the exact price before any work starts.
How long does window replacement take?
It depends on how many windows you’re replacing. Replacement windows are made to fit your openings, so there’s a wait after you order. We’ll give you a clear timeline with your estimate, including when your windows should arrive and how long installation will take.
Do I have to replace every window at once?
No. We can replace the windows that need it most now and the rest later, or do the whole house at once. We’ll help you plan whatever fits your budget.
Can windows be done with my siding or roof?
Yes. We do roofing, gutters, siding and windows, so we can handle your whole exterior as one project. Doing windows and siding together lets us trim and seal everything at the same time.
Are you licensed and insured?
Yes. We hold Maryland MHIC #158920, Pennsylvania HIC #T002933 and West Virginia #WV066492, and we’re fully insured.
