Burlington County and the surrounding South Jersey area see hot summers, cold winters, and plenty of wind and rain. Old or poorly installed windows and doors are some of the biggest sources of energy loss and water intrusion in a home.
Common warning signs it’s time to look at window and door replacement:
Properly installed windows and doors improve comfort, reduce noise, lower energy bills, and protect the structure around them from moisture. They also set the tone for curb appeal, especially your front entry and street-facing windows.
We install modern, energy-efficient windows and durable exterior doors that are sized and flashed correctly for Burlington County homes, not just “good enough for now.”
Whether you’re upgrading a few problem windows or planning a full replacement project, we install replacement windows designed to perform in South Jersey weather. From popular double-hung and slider windows to casement, picture, bay, and specialty units, we focus on tight fits, clean lines, and correct flashing around each opening.
We remove old units, inspect the opening, address obvious issues, and then install new windows so they operate smoothly, seal properly, and look like they’ve always belonged in your home.
Your front door does a lot of work in one spot: security, insulation, and first impressions. We install new entry doors that upgrade curb appeal and improve comfort at the same time. That includes solid panel doors, doors with decorative glass, sidelites, and transoms, all set in frames that are plumb, square, and properly weatherstripped.
If your existing opening is in rough shape, we can repair or replace exterior trim and address damaged framing so the new door sits correctly and closes with a solid, clean latch.
Back doors and patio doors take a beating—constant traffic, pets, kids, and exposure to the elements. We install sliding glass doors, hinged patio doors, and French doors that bring in more light while still sealing out drafts and moisture.
We pay close attention to thresholds, sill pans, and flashing details at these openings, since they sit close to decks, patios, and grade where water tends to collect. The goal is simple: a smooth-operating door with clear views and a weather-resistant perimeter.
Sometimes the windows and doors themselves aren’t the only issue—the surrounding trim, sills, and framing can be soft, cracked, or pulled away.
As an exterior contractor, we can repair or replace rotted sills, damaged casing, and deteriorated jambs around windows and doors, then tie everything neatly back into your siding and housewrap.
That helps stop water from following those weak points into your walls and keeps the entire opening stable for the long term.
Modern energy-efficient windows can make a noticeable difference in comfort and utility costs. We install replacement windows with insulated glass, low-E coatings, and proper weather stripping so conditioned air stays inside and outside temperatures stay where they belong.
We’ll walk you through options like double- or triple-pane glass, gas fills, and different styles (double-hung, casement, slider, picture, bay, and more) so you can balance performance, appearance, and budget.
Exterior doors should feel solid in your hand and secure when you lock them. We install insulated steel and fiberglass entry doors, as well as quality patio and sliding doors with modern locking hardware, to improve both security and efficiency.
We’ll help you select styles and finishes that match your home’s architecture while upgrading the seal between inside and out—so you’re not feeling cold air rolling in from under the threshold every winter.
Windows and doors don’t exist in isolation. They cut through your siding, tie into housewrap and flashing, and often sit near decks, porches, and roofing transitions. When those connections aren’t done correctly, water slips behind the cladding and quietly damages sheathing and framing.
Because Top Line Contractors also handles roofing, siding, gutters, and decks, we can coordinate window and door installation with other exterior projects. That means integrating new units with flashing, trim, and siding the right way, not just filling the hole and hoping for the best.
If you’re already planning siding or exterior upgrades, it’s often the best time to tackle window and door replacement too, so you get a clean, unified finish in one project instead of multiple disruptions.

We start with a walkthrough of your home’s existing windows and exterior doors. We look for:
Then we take precise measurements for each opening so new units are sized correctly and ordering is based on actual conditions, not assumptions.

You’ll receive straightforward recommendations outlining which windows and doors should be replaced now, which could be deferred, and what styles and materials we suggest for your Burlington County home. We’ll also note any framing or trim repairs we recommend and optional efficiency or glass upgrades that offer real value.
Everything is summarized in a clear, written quote—no vague ranges or surprise add-ons—so you can review the scope and pricing at your pace.

On installation day, we remove old windows and doors carefully, protect surrounding finishes as much as possible, and inspect the exposed framing. We correct obvious issues, set new units plumb and level, insulate and seal around the frames, and install exterior trim and flashing so the opening sheds water properly.
Inside, we make sure the windows and doors operate smoothly and latch securely before we move on.
When the installation is complete, we collect and haul away old windows, doors, glass, and packaging, and clean up both inside and outside work areas. Then we walk the project with you, demonstrate how the new windows and doors operate and lock, and answer any questions about care, maintenance, or future projects.
When you replace windows and doors, you’re cutting into the shell of your home. You need more than a basic installer, you need someone who understands the entire exterior system.
Homeowners choose Top Line Contractors because we’re a local Burlington County exterior contractor that works on roofing, siding, gutters, decks, and openings as one package.
We focus on tight, weather-resistant installations, clean job sites, and clear communication from quote to final walkthrough. You’ll get honest recommendations, not pressure—if a simple replacement solves the problem, we’ll say so; if there’s underlying damage around an opening that needs to be addressed, we’ll show you why before we do anything.
I just had top line do my windows. They did a great job. They came out. They did measurements couple weeks they come back. They put my windows out. I love them. The associate that I was working with was Maria and she kept in touch keeping me on updates for what was going onafter completion. She came back to check the windows. Make sure everything was satisfactory. The job was great. I have no complaints Maria Lalvay thank you.
Not necessarily. Some homeowners tackle the worst offenders first—like drafty front-facing windows or units with failed glass—and plan the rest in phases. During our assessment, we’ll point out which windows are most urgent and which can reasonably wait so you can prioritize based on budget and impact.
Yes. We can replace entry, patio, and sliding doors while carefully tying new frames and trim back into your existing siding and housewrap. If the siding around the opening is damaged or poorly flashed, we’ll explain what needs to be adjusted so the new door doesn’t inherit old problems.
We install a range of replacement window styles commonly used in Burlington County homes, including double-hung, casement, slider, picture, bay, and other standard residential window types. We’ll recommend styles based on your home’s architecture, ventilation needs, and how you actually use each room.
They can make a noticeable difference, especially if your current units are old, single-pane, or poorly installed. Energy-efficient replacement windows and insulated exterior doors reduce drafts, help maintain more consistent indoor temperatures, and lighten the load on your HVAC system. We’ll walk you through realistic expectations for savings based on your home and project scope.
Most small to medium window and door projects can be completed in a day or two, depending on how many openings are involved and whether framing or trim repairs are needed. Larger whole-house window replacements or projects combined with other exterior work may take longer. We’ll give you a clear, realistic timeline with your quote.
If your windows are drafty, your doors are sticking, or your home just feels tired from the outside, it’s time to take a closer look.
Top Line Contractors provides professional window and door installation in Burlington County, with solutions tailored to your home, your budget, and South Jersey weather.
