Double Hung Windows

The most common window style, double-hung windows give 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 and they can tilt in, allowing you to easily and safely clean the window from inside your home.

Casement Windows

These windows have an adjustable sash that’s hinged from one side and opens outwards. The sash is controlled by an easy to use, fold in crank handle and is versatile, opening to a full 90-degree angle or less for easier cleaning and 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

Awning windows provide a sash that’s hinged from the top and crank 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 and 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 and ventilation.

Bay or Bow Windows

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 angles and comprises 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.

Picture Windows

These windows offer a great choice for homeowners looking to make the most of their views and ensure optimal energy efficiency. Picture windows are typically larger and provide large, unobstructed views of the outdoors. They are known for their efficiency and durability, having a fixed sash and being without moving components like rails or mullions.

Hopper Windows

A popular style for basements or other tight areas of a home where you want to add sunlight and ventilation, hopper windows are hinged from the bottom and tilt 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 and fresh air.

Horizontal Sliders

Horizontal slider windows consist of two or three 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 great for areas 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, like either a casement or awning window. Such windows lend a home greater distinction while securing more sunlight and possible ventilation.

Expert Window Installation Services

At TopLine Home Improvement, we take pride in offering the highest level of workmanship in every window replacement project we complete. 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 these factors, a window is only as good as the company that’s installing it. That’s why the professional window installers at TopLine Home Improvement 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.

Reasons You May Consider Window Replacement

There are a variety of reasons why a window replacement project might be the right option for your home. Whether your goals are primarily aesthetic, functionality-related, or based on other personal preferences, a window replacement project can be a smart investment in your home. Here are some of the top reasons why you may want to consider replacing your windows.

Heating and Cooling Costs

Energy expenses are one primary reason a homeowner would change their windows. The quality of your windows can degrade dramatically over many years, preventing indoor air temperature from being maintained as a result of temperature transfer and air leakage. This creates the need for more heating and cooling, increasing a home’s carbon footprint and 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 other deterioration can prevent a window’s components from functioning properly. Repairing a window is not always a lasting solution, and 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, and unpleasant levels of noise into a home greatly reduce indoor comfort. Weaker glass packages and 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, and too much outside noise.

Thank you to all our wonderful customers!

I didn’t know what to expect when I got my windows replaced, but I must admit it was a very pleasant experience! The 2 man team worked efficiently and as inconspicuously as possible and they cleaned up after themselves completely. They were also very polite. I would highly recommend TopLine to anyone who needs to replace their windows.
Erin Rollano

We called a few places to get estimates for roof and gutter work on our house. Thank goodness a friend highly recommended Topline. They were responsive and considerate when discussing different approaches to the work and coming up with a solution to meet our needs. The estimate, and later contract, was more than reasonable and the job was scheduled in a timely manner. The workers showed up on time, did excellent work, were professional, and left the place immaculate. We couldn't be more pleased. Topline is the best!

Always a great result when dealing with Topline. From the quality of their windows to the installation. Couldn’t be more pleased with the outcome. Nick came by and was just awesome! He’s the best. So helpful and everything was completed without a glitch! Their installation technicians are truly amazing. Clean work and the most professional finished jobs always. Thx u so much Nick!

Topline installed 2 windows and replaced the awning above the bay window. I visited the store on Utica avenue to see windows and doors - the lady was very friendly. Nick sold me the windows. He explained the window features, was patient with follow up questions, was excellent at giving me updates after I placed the order, and followed up after the windows were installed. It took about 5 weeks between ordering and installation. Luis and his team did a fantastic job installing the windows/awning. I appreciated that the crew cleaned up afterwards. Overall, I am happy with the windows and would order again from Topline. Excellent customer service, professional, and quality workmanship.

My family has been using Topline for over 25 years for doors, bay and regular windows. I had a minor hiccup by one of their installers and Topline contacted me immediately. They took ownership and were accountable and took action. Tom from Topline came to my home and made amends. A true gentleman with integrity and outstanding customer service and care. I need two more new windows installed soon and definitely I will contact Topline again. I HIGHLY RECOMMEND TOPLINE for all your home improvement needs.
Patrick Rochford

I dread home improvement projects. That’s why I call Tom at Topline. The vinyl siding that they installed looks wonderful and the whole experience was stress free!

Excellent customer service
Rose Parker

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.

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.

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.
