Window Replacement & Installation

Guaranteed Expert Installation

Even windows of the best quality will underperform if not installed correctly. Improper installation can cause the loss of heat, cracked joints, as well as the infiltration of air and moisture which can cause damage to both the window and overall structure of a home. Given this, a window is only as good as the company that’s installing it. That’s why our professional window installers are factory trained and certified and are held to the highest standards throughout each project. From proper sizing and alignment to using the highest-quality materials when sealing, our quick and clean installation is detail oriented and done right the first time so your new windows will perform as advertised for decades to come.

Double Hung Windows

The most common window style & gives a traditional look to any home. These windows have two separate vertically adjustable sashes so they can easily be moved up & down for ventilation. The sashes interlock for great energy efficiency & tilt in, allowing you to easily and safely clean the window from inside your home.

Casement Windows

Has an adjustable sash that’s hinged from one side & opens outwards. The sash is controlled by an easy to use, fold in crank handle & is versatile, opening to a full 90-degree angle or less for easier cleaning & more ventilation options. A lever lock on the side of the window ensures an airtight seal between the sash & frame for exceptional energy efficiency.

Awning Windows

Provides a sash that’s hinged from the top & cranks out from the bottom via an easy to use, fold in handle. It opens to a 45-degree angle, giving it an awning like profile & allowing for ventilation even when raining or snowing. Being a smaller size, awning windows are great for tight areas in a home where you want to obtain more sunlight & ventilation.

Bay or Bow Windows

Excellent options for any room you’re looking to add sunlight & space to. These windows project outwards with an insulated head & seat board that has a furniture grade birch finish. A bay window provides a deeper projection of either 30- or 45-degree angels & comprise a choice of double hung, casement or picture windows. Bow windows are arranged with casement or picture windows, have a shallower projection of 10- or 15-degree angles & give a stylish curved exterior for a more classical look.

Picture Windows

Offers a great choice for homeowners looking to make the most of their views & ensure optimal energy efficiency. These windows are typically larger and do not open, providing a window style without rails or mullions for large, unobstructed views. Picture windows are known for their efficiency & durability, having a fixed sash & being without moving components.

Hopper Windows

A popular style for basements or other tight areas of a home where you want to add sunlight & ventilation. The windows are hinged from the bottom and tilt in 45 degrees by way of an easy to use, locking handle that gives an air tight seal when closed. This style prevents dirt or other debris from entering a living area while brightening up a space with light & fresh air.

Horizontal Sliders

Consists of two or three separate horizontally adjustable sashes that can be moved right or left for ventilation. The sashes operate on a smooth glide track for effortless operation. Having a sleeker frame, sliding windows are great for securing unobstructed views and improving sunlight exposure. These windows are a befitting choice for areas of a home with little vertical space.

Custom Shaped Windows

These windows provide options for more dissimilar or different types of window openings in a home. Custom shaped windows are typically manufactured with either a stationary window sash, like a picture window, or a crank out sash, similar to either a casement or awning window. Such windows lend a home greater distinction while securing more sunlight and possible ventilation.

Reasons You May Consider Window Replacement

Heating and Cooling Costs

Energy expenses are one primary reason a homeowner would change their windows. The quality of particular windows can degrade dramatically over many years, preventing indoor air temperature from being maintained as a result of temperature transfer & air leakage. This creates the need for more heating and cooling, increasing a home’s carbon footprint & energy costs.

Difficult to Operate & Lock

A sign that a window has reached its total life span is when it has become difficult to open or lock. In time, any sort of impairment from warping, water damage, dust build-up, or otherwise can prevent a window’s components from functioning properly. Repairing a window is not always a lasting solution & typically the most cost-effective way to address the issue is by replacing the window.

Excessive Drafts, Sunlight & Noise

Windows that allow the flow of outdoor air, UV rays & unpleasant levels of noise into a home greatly reduce indoor comfort. Weaker glass packages & faulty window compositions can regularly impact the living experience inside a home by occasioning cold or warm drafts, the fading of interior objects by UV rays & too much outside noise.

Thank you to all our wonderful customers!

Nick & Jimmy and the entire team at Topline were incredible to work with! We had originally just planned to replace our roof but we loved the work so much we also changed our siding, installed new gutters and a new front door. The consultations before, during and after were beyond helpful. The materials used were of high quality and the staff working on the job was always attentive to detail. We are exceptionally thrilled with the results and can't say enough great things about this company. We highly recommend them for any house project you may be interested in...the results speak volumes about their professionalism.

Had a total siding job with new gutters and 3 windows installed a month ago. I am very pleased with the work. Antonio and Pascual were outstanding! Did a professional and detailed job with the siding. There were one or two things I pointed out to Antonio that had to be adjusted, and he worked to do them seamlessly. I had bought paint to refinish one of the gutters, but he said, no, I'll clean it. I was skeptical, but he cleaned it so well, the gutter was sparkling when he was done! I can't say enough about those two guys. Tom sent his best team and they did a phenomenal job! I had been scheduled to leave on vacation, and Tom made sure the team came and completed the job before my departure deadline. Tom and his office staff were always available to answer any questions. Would use this company again.

A neighbor recommended Top Line for siding and door work. The crew did a great job installing insulation and siding on my old frame house in Brooklyn. The team was prompt, communicative and tidy with tools and materials. They finished the job on time and on budget. Thank you! They will be coming back soon to replace exterior doors.

The Cement Board Hardie siding of my building was ripped off at the second story level by a passing truck that caught a FIOS cable strung across the street. For almost a year during the Pandemic I tried to find a company that would do this repair. I finally called Topline and they were willing and able to complete this repair quickly, accurately (it was difficult to match the exact siding size, shape, texture and color) and efficiently. I was extremely pleased with the speed, cost, and quality of the work that this company provided. They would be the first people I call if I ever need a similar repair. Highly recommend.

Amazing service. Highly recommended. Nick came by and walked us thru the options including what he suggested and what we were thinking. All pros and cons for each option in order for us to make an informed decision. It wasn't as cheap as home depot or lowes, but the service and quality is definitely much better. He even suggested we go with a cheaper version that was better for our needs as opposed to making the sale. We ended up delaying a decision and Nick was very patient until we finally decided, constantly answering questions and concerns we had (although he probably thought we weren't going to finalize). The morning of installation came and they showed up. Did half the job in the first day, came back for the rest on second day (multiple windows on multiple floors) and cleaned up EVERYTHING. No mess anywhere. Additionally, my kids left a mess and they worked around it all. Moved furniture as needed and back afterwards. Very impressed. This was a few months ago. I waited a while to see if the job would hold up thru all seasons before posting. True to their word everything was as he said. If you are thinking of updating any home improvements, only use topline. Real customer, real experience, really satisfied. Pro-tip: don't go into the showroom without Nick. 😉 No pictures because we were at work during installation. No mess to record afterwards.

Got my gutters done last year. My father in law asked for my guys number. Well, I recommended TopLine very easily based on my experience. He did my neighbors house next door. They were quick, neat, and the job came out excellent. They did less work on my house, but it was treated just as important. TopLine showed up, but I had an early appointment for work, so I didn’t meet with his actual employees. Mike gave me an estimate and instructed his crew according to my homes damage. Everything was already done when I got home. More than highly satisfied. Everything was repaired but there was no evidence, they were there. They were very tidy. Being that I was able to recommend TopLine to my family and also took the number from my neighbor; I figured on leaving this review as a thanks and appreciation for their professionalism. Highly recommended.

After receiving quotes from other well known HI companies with fast talking sales pitch, a friend recommended Topline HI. Mike came out and surveyed the job and quoted me a price that was almost $6K cheaper to do the very same thing the other companies doing. I was given a 6 weeks timeline to get the windows but they came sooner. They arrived on time to start the job and Juan and his crew was very professional and respectful. They did an excellent job that I'm pleased with. Even my neighors love the outcome. I will highly recommend Topline Home Improvement to anyone that looking to do siding and windowsServices: Home renovations, Window installation
