Enviropro Basement Systems
Enviropro Basement Systems
12 Employees. No subs. cost is determined by the job. No travel charges. Ask about Angie’s List discount. License number: 13VH01277500.
"To mirror another reviewer: we were also "extremely pleased with the job Enviropro did in our basement. The price was reasonable (relative to others we contacted), and the sales call was friendly without the high-pressure nonsense of some other waterproofers (*cough*midatlantic*cough*)." The company was prompt, responsive, and friendly. Mike even came out on a weekend for the estimate. The night before the installation, we had heavy rain and water appeared in a section of the basement it had never been before, so the plans were changed the morning of the work with no issues. The crew was friendly, clean, and even indulged my very curious toddler. I HIGHLY recommend EnviroPro!"

Alco Windows Inc
Alco Windows Inc
ALCO Windows and Services Inc. was founded in August of 1994 focusing on home improvement and windows replacement. A few years later we partnered with VEKA and became an official fabricator of an exclusive vinyl window line. That is a top grade design available in new and replacement windows like double hung, casements, bays, bows and sliders. Located in a small building we began manufacturing windows with just thirty employees and a single product line. The product line consisted of an all vinyl, fuse-welded double hung window and horizontal sliding windows. In the years that followed ALCO Windows, Inc. added three more window lines consisting of more than 15 types of windows and sliding doors. In 2002 due to the growth in the volume of windows being produced ALCO Windows moved to a larger facility. This move increased ALCO Windows manufacturing and storage capacity by another 50%. ALCO Windows, Inc. now offers a diversified array of vinyl windows and doors in a variety of colors for every application.
"Work was done quickly and efficiently. Quality of the effort and the windows was very good (they were not premium windows) and looked and functioned as well as any window I've used. The install quality was very good and I being somewhat picky, was very surprised and satisfied with the work. After work was done and inspection, there was no need for a call back. All good, and would hire again."

"After a terrible experience with Egress Systems Inc. not showing up on contracted date I contacted Steelway to see if they could get my egress installed before my basement reno started in a week. Tate came out to see the space early the next morning to accommodate me since I was leaving for vacation that morning. He even gave me his cell phone #. They gave me a fair price and were able to squeeze the job in before construction started. Everything was smooth and easy. They were prompt, provided excellent customer service, and we are very pleased with the job. I highly recommend Steelway for egress window install."

FAQs for egress window service projects in Williamstown, NJ
The cost to install an egress window is $3,900 on average. This cost can be as low as $2,500 or as high as $5,300, depending on the window size, the number of egress windows installed, and the glass quality.
Double-pane windows average between $200 and $500 per window, whereas single-pane windows are more cost-effective at $100 to $400. More luxurious triple-pane windows are more expensive, ranging from $300 to $800 on average.
It can take up to three days to install an egress window. The window installation team will typically spend the first two days excavating the land where the window will go. If you’re replacing an egress window, it will be spent cutting the foundational wall to accommodate the window, if needed. Often, a window inspection is required to verify that the window was sized and installed correctly.
An egress window is similar to a regular window. However, this type of window opens fully to allow people to escape the home or rescue personnel to enter the home if an emergency occurs. Egress windows are required in all finished basements before they can be considered a living space.
Not only does an egress window add value to your home, but it’s also a basement requirement in most areas. Egress windows offer a 70% return on investment, making them a worthwhile purchase and installation. In addition, most building codes require an egress window to be used as an emergency exit and entrance. Therefore, it is a necessary addition to meet building codes.
There are a few ways to save money on egress window installation. First, choosing pre-fabricated windows instead of custom windows can help dramatically reduce the overall cost. In addition, skipping window extras, like customized frames or window film, can help save money on the price tag without sacrificing the window itself. You should also shop around to multiple window installers to find the best installation deal without sacrificing the quality of the window.
